Summary: The integration of information systems, or of data sources, is an urgent need. The quantity of industrial projects and experiences about this subject is evident. While the integration problems on the technical or system level can be considered as solved, the semantic level still needs a substantial amount of research. This thesis aims to tackle this problem area. It is focused on the integration of spatial data sources in order to achieve a solution as solid as possible. Many previous approaches on integration of heterogeneous data sources show that too generic solutions are often impossible to pass from the theory to the practice. Therefore, focusing on a specific application domain this solution may be closer to concrete results. In the first two chapterstwo chapters an overview on the problem of database integration is given and the relevant literature is reviewed. Then on the third chapter three the integration approach, which works on the conceptual level, is introduced, thus the way how to model geographic information is shown and some additional characteristics in a spatial data model are introduced. Chapter four presents theA Variable-Depth and -Level Spatial Ontology (VDLSO), has been designed as part of the Semantic Integration Tool for Spatial Data (SIT-SD) project. In Tthis ontology has been determinesd the main spatial characteristics to be used in the work with spatial objects. A multi level approach on the ontology is considered for facing multi-resolution and multi-representation problems. This is achieved It is getting by means of defined- in- advance views, which could be looked like a pruning process in order to âexpand' or âcontract❠the knowledge in agreement with application needs. Thereforeus, the ontology depth should change from abstract knowledge towards more detailed concepts. Chapter 5 is devoted to the proposal of The a framework proposed on for integration of spatial data sources, a framework whichapproach, on fifth chapter, is based on the BLOOM Federated Database architecture (developed in the TechnicalPolitecnic University of Catalonia)unya), which is based on Federated Database Architecture. This The ontology is used on the integration level of the software application designedin (SIT-SD). Since this work is focused on spatial sources, it takes advantage from spatial characteristics explicitly represented in the applicationâs schema. Thus Therefore in the software application designed (SIT-SD), profits from lot of the additional semantic information present in this kind of systems. A semi-automatic strategy for integrating based on semantically similar object classes across different spatial database schemas is used. This is done by mapping classes of export schemas onto the ontology, and with a set of similarity functions (Word Matching, Feature Matching and Neighborhood Matching), and by identifying a common super class that is able to subsume classes to be integrated. In the last partIn chapter six some important issues are discussed by means of a mobile applications scenario is discussed. Thus the possibility of implementing other tools that can use this ontology and the assessment process of semantic similarities among spatial object class is kept open

Summary: There are many situations in the real world in which data we can observe and quantify only have a certain relationship unfamiliar with the data that actually are the subject of interest. Moreover, it is evident that marked trend in the scientific community to trust the solution of real problems paradigms based on biological models. Somehow, it is imitating the reasoning or human behavior observed in nature. Such is the case of techniques based on neural networks, fuzzy logic or reasoning by the paradigms mimicking the process of natural evolution. In the latter category fall genetic algorithms, implementing procedures for search and optimization on space solutions based on the principle of âsupervivencia of more dotadoâ (Darwin 1859). This dissertation work focuses on solving the problem of blind separation of signals for different types of mixtures linear and nonlinear, using techniques based on evolution, more specifically genetic algorithms. We present two algorithms called GABSS and PNL-GABSS for the separation of mixtures of signals linear and non-linear mixing (model post-no-lineal), respectively. In the first case (linear mixing) solution to the problem is limited to finding a matrix coefficients of linear coefficient multiplied by the mixed signals we return the original signals. The solution proposed in this dissertation on this case, based on genetic algorithms, is to find a solution that corresponds to a separation matrix that maximizes a certain function that evaluates the independence of a set of estimates. As for the situation in which the mixture is not linear, find the components without more independent is not a sufficient condition for finding a solution to the problem of the separation of signals and need additional information. In this investigation we have assumed that the model is the post-no-lineal. This model imposes the constraint that the mixed signals are generated from sources following a linear mixing followed by a nonlinear transformation in each channel. Thus, the separate components that are obtained coincide again with the sources sought. The proposed algorithms have been rigorously validated by simulations and statistical analysis of experimental results, demonstrating the effectiveness of this new approach to the problem of blind separation of signals.

Summary: Every day more health care for a patient is the shared responsibility of a group of professionals from different disciplines and institutions. As a result, it is vital that health care institutions can share health information about patients, a simple, safe and preserving the original meaning of the data. The challenge is to provide any health professional involved in the care of a patient clinical information they need to do their jobs, that is their medical records electronically. This thesis addresses various aspects related to the integration of clinical information distribuidad. The aim is to provide a comprehensive and integrated view of clinical information distribuidad across multiple heterogeneous information systems and autonomous. The proposed solution considers the latest developments in the field of electronic medical records, specifically the approximation based on the dual model of information architecture for communication of the electronic medical record and the rule prEN13606 European Committee for Standardization (CEN). The most notable contributions of this thesis are:-Using dual model information architecture for communication of the proposed electronic medical record in European Standard EN13606 CEN a system of federated electronic medical record, where the scheme managed by Land the system consists set of concepts clinical formalized as archetypes. - Proposal of a data model based on trees tagged for the representation of clinical information consistent with EN13606. - Proposal for a mechanism based on the types of data model as previous formalism of the definition section data of the archetypes. - Development of a method for the publication of clinical information already existing in accordance with the European standard EN13606. - Design and implementation of PANGEA: an information system based on EN13606 that Land offers a comprehensive, unified view of clinical information from patients in a number of distributed heterogeneous information systems and autonomous.

Summary: Currently, there is a strong interest in information systems to facilitate the process to companies making strategic decisions. The Data Warehousing (Data Warehouses, DW) contain important historical information, which usually comes from various sources of operational data, to make these decisions. DW These should be supplemented by analysis tools that extract data from a fast, in a format that is easy for the analysis. Probably the most frequently used tools so far for this purpose are the tools of online analytical processing (On-Une Analytical Processing, OLAP). In recent years, there have proposed various approaches to address the conceptual and logical design of the DW. Normally, the conceptual design of a DW has been approached from the perspective multidimensional (MD). However, none of these proposals has been widely accepted as a standard method to tackle the design of a DW. Given the wide variety of models used in the different phases of the design of the DW, it is absolutely necessary to develop a standard method as possible to provide design guides for creating and transforming these models during the analysis and development of a DW. Moreover, so far, most research in the area of modeling of DW has focused on end users (front), while few proposals have focused on the modeling of the internal processes of DW ( back stage). On the other hand, lenguajede modeling UML (Unified Modeling Language) has been widely accepted as the standard language for object-oriented modeling. Along with UML, has developed the method of development UP (Unified Process) specific to be used with UML.EI main aim of this thesis has been to define a comprehensive approach object-oriented (00) that integrates all phases of the design DW from the sources of operational data to the final implementation, including the definition of ETL processes and user requirements. The proposed method provides a balance between power of expressiveness, ease of use and ease of understanding by end-users of DW. The method we propose organizing the design of a DW into five phases and three levels: 'Phases design: Design or sources datos.o design level of integration between data sources yel DW.o design DW.o Design of level adaptation between DW and structures of clients employed by users finales.o design structures customers. "Levels of design: apply three levels typical data modeling: or conceptual level. Physical or Nivellógico.o level. Since the five phases and the three levels, provides an array of fifteen diagrams that are offered to the designer. According to the particularities of each project facing, the designer chooses to use diagrams that need. Of the fifteen diagrams method, the most important and which are considered essential are:. The conceptual framework of DW: For this we propose an extension of UML for the conceptual design of DW according modeling MD. Our proposal allows represent major properties MD at a conceptual level, as are the relationships muchos-a-muchos between facts and dimensions, warped dimensions, hierarchies and multiple alternative path, and so on. This model has three levels: Level 1: Definition of the model, consisting of schedules stars. Level 2: Definition of a star schema consisting of facts and dimensioneso Level 3: Definition of a fact or dimension. The diagram mapping between data sources yel DW: related data sources with the DW, in a way that allows to know the provenance of a figure in the DW.El diagram of ETL processes.

Summary: The classical models of the transmission of information com Shannon and Weaver still are generally regarded as the only possible scenarios in which signal processing applications can be formally modeled. Meanwhile, other disciplines such as Information Technology have developed different paradigms that provide an opportunity to look at the same problem from a different perspective des. One of the most commonly used approaches for the analysis and design of software is the Object Oriented paradigm, which proposes a system modeling objects and relationships between objects. An object is an instance of an abstract concept or the real world consists of an identity, a state and behavior. Thus an object-oriented system is described in terms of its internal objects, messages that are passed between them and the way that these objects respond to incoming messages implementing a specific method. Although object-oriented technologies have been applied to signal processing systems, no previous attempt to move all the advantages and implications, both practical and formal, this paradigm to the domain of signal processing. This paper defends the thesis that a system of signal processing generic can be described completely and effectively using the object-oriented paradigm. To do this, Metamodelo of Signal Processing Oriented Object offers a classification of objects according to their role in a system. The objects are classified into two main categories: processed objects and objects that act as containers of data. This meta-OO happen to be very close to the Networks Process Flows data with a computer graphic model that has already demonstrated its utility model system for signal processing. In our study highlight the similarities of the two models to conclude that object orientation is actually a set of above-oriented models in the process and that, therefore, the object-oriented paradigm can be proposed as a generic approach to modeling systems. Furthermore, it appears that today the environment destination for many applications of signal processing is the computer and its associated software and object-oriented paradigm is an environment where diverse natural conceptual stages of development suited. CLAM (C + + Library for Audio and Music) is an environment for developing applications for audio and music that has been designed bearing in mind this conceptual model. CLAM is both the origin and proof of concept Metamodelo. On the one hand the design process has led to the definition of the metamodel. On the other hand, demonstrates that the proposed metamodel is more than a wish list abstract and can be used to model applications and efficient in the specific domain of audio and music. The meta-core signal processing Oriented Objects can be extended to include the idea Processing Based on the Content. OOP Concepts like Hierarchies Inheritance, and Polymorphism the Late Link can be used to model classification at runtime objects middle or to manage information in the signal semantics, rather than just treating the signal in itself . This leads us to define a new metamodel transmission of the information, unlike their predecessors, they are concerned about the meaning. Finally, the OOP paradigm can also be used to shape new domains symbolic highest-related signal processing. For example, music (everything in its power) can be modeled in an effective manner using OOP paradigm. It proposes an OOP model of music as meta-analysis of the basic signal processing, i language MetriX is presented as proof of its concept.

Summary: In this thesis we present the COSTUME method aimed at the construction of COTS-based system quality models. The method describes a set of activities which allow the construction of system level quality models, by composing individual quality modes of its constitutive system actors. The method is supported by a set of knowledge repositories, which are intended to abstract and store several of the deliverables obtained in the process and allow for their future reuse. The method proposes four main activities to drive quality models construction with a well defined rationale which increases the efficiency of the process whilst improving the reliability of the deliverables. Resulting quality models include quality features that have been proposed in the literature and also refine some of them. Quality models are constituted by a set of high-level quality characteristics (the ones proposed in the ISO/IEC 9126-1 quality standard), and hierarchies of subcharacteristics and quality attributes (basic and derived), for which COTS systems can be evaluated using the appropriated metrics. Relationships among quality features (other than hierarchical ones), are also included in the quality models to improve their applicability. The first activity of COSTUME is intended to define a model of the system and its environment; to do so, agent modeling techniques are used, namely Yuâs [Yu95] i* modeling approach. In the second activity, five steps are used to explore and detail the insides of the system. An i* SR system model is constructed and the goals and sub-goals included in the model are grouped into system actors. System actors define atomic COTS domains for which COTS components can be identified. System actors are not expected to be mapped in one-to-one base to COTS components; the main purpose for their identification, in our case, is that they define the domains for which individual quality models are to be constructed. Activity 3 of the COSTUME method describes the IQMC method for the construction of individual quality models of the identified system actors. This seven step method is used to explore the domain defined by a single system actor and departing from the ISO/IEC 9126-1 catalogue, construct a quality model aimed at the evaluation of COTS components in the domain. In a preliminary step 0, information relevant to the domain is retrieved, analyzed and a conceptualized into a UML conceptual model of the domain. Using this model as reference, the additional six steps of the method can be iterated or intertwined to obtain all the appropriated quality features of the quality model (characteristics, subcharacteristics, attributes, metrics and relationships among them). In activity 4, the individual quality models resulting from activity 3 are composed into a single COTS-based system quality model, by systematically applying several quality models composition rules identified in our research. The resulting model collects the elements of the individual quality models, but also incorporates some relevant only to the system as a whole. In this way the final deliverable becomes a reliable and understandable framework, which can be used for the evaluation of the resulting COTS-based system as a whole. Artifacts to store refactored deliverables of the process have been incorporated to improve knowledge reuse. Theses artifacts define an experience base similar to the one outlined in Basiliâs experience factory approach. The first layer of this two layered experience base includes four main repositories: an attribute patterns repository, a COTS domains taxonomy, an environmental patterns repository and an environmental models repository, aimed to support the four main activities of the COSTUME method. The second layer includes final models resulting from the process which can be reused as departing base in similar future experiences.

Summary: The estimated project deadlines is a critical task, which could lead to failure of the project, due to the lengthening of the duration or a bad estimate of the effort needed to run it. You need a tool that will help us to have more knowledge about the project to select variables influential on departures of the project and to provide estimates more tight. This paper discusses the feasibility and advantages of developing a system based on artificial intelligence techniques, able to select the variables that affect the duration of the project and the effort required to do this from a set of historical data, compared with current techniques. It takes as a data set from the closing of projects compiled by the ISBSG, which apply the steps of the methodology of data analysis to examine the quality of information finding joint projects anomalous in relation to the other, and missing values and the presence of large number of categorical variables. To that end, we propose a method for the analysis of existing data preprocessing and to get a model that fits the needs of the project manager. They apply data mining techniques to solve these problems preparing the data for the modeling method using MARS multivariate adaptive regression splines. With which have exceeded the targets set at the beginning of the work.

Summary: Failure to file and ineffective management of the working papers generated in each project has a negative impact on time-to-market for a new product at its cost, in the motivation of workers and customer satisfaction. In other words, the knowledge gained by teams working in the design process are only as individual knowledge and not become part of the general knowledge of the company and are therefore hardly transferable to new engineers, designers, etc.. After studying the characteristics of the development of a vehicle in the current situation, we can say that it is necessary to move towards a cooperative future, starting with an initial collaborative stadium that has led to the development of the system âMERIDAâ for the specific case of Audi AG MERIDA (Multipurpose Engineering Resources for Information and Development of Automobile) enables tracking of decisions during the development process as well as knowledge management and the experience gained in the development of a vehicle. Through MERIDA get the following uses and benefits:-Reduction in the cost of redundant search for solutions, through transparency and reasoning of decisions. - Improving the monitoring of problems maintaining the history of the evolution of the problems during the process of finding solutions. - Improving the quality through a single source of information for developers argued pieces. - Reducing development time through the automatic generation of standard reports and custom definition of other reports by the user, without implying any loss of time. - Reducing costs through the sharing of monitoring decisions by individual departments, as well as the unification of reports and analysis of competition.

Summary: In the information society and knowledge is essential to eliminate all those obstacles that may prevent people's access to any kind of technology. The Geographic Information Systems (GIS) are software tools that combine geographic knowledge, digital mapping and the potential for management of information technology to enable the management and analysis of all the information component with a "space". As it is estimated that 90% of databases (in digital format), the potential number of users is very high. But many of them do not use these programs, despite the great potential that can bring, because of its difficulty of use and a certain "elitism" caused by the complexity of Science and Geographical Information Technology. To manage spatial information is necessary conceptualizarla and modelizarla, but to do so must provide a minimum level of training not available to anyone. To this should be added difficulty learning long and costly on utitilización a GIS. Besides the development of Geographic Information Systems is mainly due to commercial pressures and the needs of some very specific users. It has generally lacked scientific thinking able to provide a solid theoretical basis and consistent. This deficiency increases the difficult access and the definition and development strategies and design training courses. Moreover, after any process of analysis or management with GIS, it is often necessary to generate a series of issue papers by which to communicate the results. The thematic map thus becomes a real means of dissemination to convey ideals. But increasingly, most of these maps have been created by people with no knowledge of the semantics used for the graphic language is called "Semiology. This is a specialty born in the sixties, combined with the possibilities of graphic current computers, has come a new specialty called "Scientific Visualization." This thesis focuses on the development of a theory (TCTF-SIG), which combine components of the Geographic Information (conceptualization), the functionality of treatment of GIS (modeling) and the attributes and associated data. Besides proposing an adaptation of the graphic Semiology to Scientific Visualization for the automatic creation of thematic papers using GIS in the search for a unified proposal and a common, universally applicable, in creating these documents. As a result of these proposals are fixed a set of goals aimed at the removal of barriers to access to this technology which may include: facilitating learning and use of these programs, to avoid mistakes in the management with GIS, and facilitate the conceptualization model building, develop a methodology for assessing programs, avoid mistakes semiológicos in creating documents and allow the development of training using cutting-edge learning methodologies.

Summary: This work is part of the research field of online hypermedia applications in the educational context To this end we refer to the interactive computer programs that show digital information (text, graphics, audio, video, animation) via online , in order to facilitate the teaching-learning process. Many empirical studies that show the benefits of hypermedia applications in education so their development is critical and requires theoretical and practical references to ensure a process of proper development of quality products for this purpose, work and innovation research Lab Multimedia Applications at the Universitat Politecnica de Catalunya has been aimed at improving the processes of design development and exploitation of these products result of this investigation, it has expanded the knowledge base and has been given any solution to the problems of item on;) but also new issues have emerged that affect the development process and that, once again, have led us to seek solutions adapted to the new technological resources in which society is immersed As regards the development of applications one of the problems identified was the mixture of content with the presentation format it difficult recovery content items and generally managing them. In the best case, after reviewing the codes and files applications designer getting locate the object to be updated or reused too often resorted to the reprinting and thus caused delays and cost in the development process Another problem no less important was that the number of files generated depended on the number of times each template was used in the editing of the content, making it difficult managing them, even though they had a modular development and independent In this thesis presents the development of WED (Structured Information Model), as an alternative model for organizing the content in the development of educational applications hypermedia (AHEs), with a focus on the structure of the information WED The proposal defined from a frame of reference teórico-tecnológico and analysis of multimedia content that has served as the basis for improving the design of the applications. This framework integrates diverse areas of knowledge engineering hypermedia, educational technology, instructional design and technology XML (Extensible Markup Language). The WED was designed and implemented following the steps of the construction process of Structured Information model proposed in this thesis. It also, in this thesis assessment tool MIEX (Structured Information Model with the support of technology XMI), which implements the MIE, editing AHEs. The assessment includes an empirical study conducted in the framework of DESMET (Methodology for the evaluation of methods and tools in software engineering. This evaluation was conducted by applying the methodology of the case study for product replicated in which a portion of an existing product was reimplementada using MIEX The objective was to compare the effects of variables effort, number and size of files l 8 os same 469 s results show that, using MIEX, the time of publication of multimedia educational materials was much minor and increased productivity in uro I%. The study shows that the use of structured information also includes other benefits, including the generation of fewer files and a clear separation between content and presentacíón, which implies better organization of the files, and better management of content

Summary: This thesis considers the definition and implementation of a software architecture that conforms to the new model using the multimedia standard MPEG annotation. The creation of applications that take advantage of the metadata required to devote a considerable effort to develop a layer of compatibility and achieve a proper synchronization with the rest of tasks present in the life cycle. These tasks concurrently working document using metadata, a common resource shared by all processes. In the definitions of the standard metadata annotation lack a paradigm of efficient application development. The proposed architecture offers support for the development of applications at any stage of life cycle through a multimedia approach that facilitates distributed concurrent processes and maximizes performance. They are defined and implemented, also, a number of basic services whose aim is to provide the architecture of a layer of functionality that is sufficient to resolve common issues and to enable to focus development in the real purpose of the applications. These services include facilities for access to distributed multimedia content and metadata, for the acceleration of local processes based on the use of the graphics processor (GPU) for access to key components of multimedia content (frames and samples) and for reuse results between components locally. The biggest effort has been devoted to the creation of a core layer of automatic analysis of all the tasks of the life cycle can benefit. It also proposes to use examples of architecture in the process of developing real applications. Two applications are described in this context. The first deals with the production of metaproducciones derived from existing content. The second application is concerned with the identification of digital video issued by entities distribution.

Summary: Since the beginning of the information age reuse has made a practice for the development of software applications. Currently, the reuse of software remains a key component in existing information systems by the use of software components, viewed as collections of reusable code that facilitates the development of applications software. The emergence of web services has provided a different model for application development, offering the ability to access different services in a unified and interoperable via the Internet. New web applications are created by combining Web services composing or heterogeneous. Unfortunately, current developments pay little attention to the reuse of compositions of services, as a mechanism to facilitate and reduce the existing complexity grows, the number of web services involved in a composition. The most important contribution of this thesis has been to provide an approximation for the composition of web services in order to facilitate the development of web applications based on flexible and reusable. On the one hand, the proposed approach introduces the concept of integrated component, seen as a basic unit reusable, which integrates the most important characteristics of this reuse based system software components and in the area of workflow. Moreover, this approach describes a methodology for the creation of composition, composition, reuse of components to transform finally executable processes.

Summary: This dissertation provides an innovative model processes for the adoption of engineering-based Family Systems. We have analyzed the situation that characterized the adoption of the Family-Based Engineering Systems, as well as the situation in terms of models for improving current processes with greater overall impact. Then, has developed a new model of CMMI processes r -SFE extending the model r CMMI processes for dealing with the adoption of the Engineering Building on Family Systems. The empirical validation of this model has been carried out in two contexts business, telecommunications and aerospace technology. This validation has been done in TELSA and Eros in which the model has been evaluated. Both organizations have described the model as an appropriate mechanism to establish and clear what practices were to establish an organization towards institutionalizing Engineering Based on Family Systems. At the same time has enabled them to establish the strategy for improving the organization should continue both to achieve a desired maturity, to take the dome Engineering Based on Family Systems without the need to establish two parallel improvement programs. The previous findings by the organizations in which we have conducted the validation of the model allows us to conclude that the hypothesis raised as a point of departure for this investigation, "By integrating the practices of the Engineering Building on Family Systems model processes used globally, the adoption of the Family-Based Engineering Systems will be identified by the industry as a process of improvement. " True, since the CMMI model r -SFE integrated into the model r CMMI Process Engineering Based on Family Systems, and is seen by the organizations evaluated as another improvement process in the integrated model CMMI r

Summary: One of the main requirements of the digital rights management on the Web is a shared language for the representation of copyright. The current estimates are based on purely syntactic solutions, simple and difficult to implement. The contribution of this dissertation is to implement an approximation semantic web ontologies in the digital rights management. It develops a Ontology copyright whose pieces are a model of creation, copyright and actions that can be conducted on the contents. Ontology This facilitates the development of rights management systems. It has been applied the semantic approach to the main languages of expression rights. Have been integrated with the ontology to evaluate and yet have enriched their base semantics. Finally, all this has been implemented in a system semantic management rights.

Summary: The budgeting project as software programmers or telematics, is still a major challenge to the profession, despite the fact that especially since the decade of 1970 have been proposing methods, techniques and tools that pose significant contributions Research, Development and Innovation. The budget process for software projects data processing and data transmission begins with the stage of "Measurement of budgeting," which is the basis of the budget process, which still stages of resource estimation, budget costs for the supplier, and Price supply to customers.

Summary: The conceptual modeling techniques are an essential component in a large number of ways to develop information systems. However, normally spend very little -- or ningunaâ attention to the problem of validating the conceptual framework. This paper explores a technique that, based on the conceptual scheme, allows specification of the information system that are formal and comprehensible to users. The technique is proposed that is based on axiomatización of the forms business. To do so, defines a grammar that allows voice using formulas and forms company is a procedure that allows transform the conceptual framework of formulas that grammar. The conceptual framework and transformed represents the set of axioms of the calculation, using a set of inference rules that are being proposed, yields, as theorems of calculus, the forms used for the user. Thus, the user can validate the conceptual framework through the forms to be used, and also get a formal specification of the system to build that programmers do not malinterpretarán. To compare the proposal with other approaches to the problem, is studying specific proposals in the areas of software engineering, ontological engineering, design ontological, conceptual modeling, standardization of databases and the methods of formal specification of systems. It shows that the positions that keep these proposals with respect to the notion of information are different and sometimes contradictory. To show this, we study the different positions they have maintained throughout the history of various philosophers compared to the notion of information. A deeper understanding of the philosophical assumptions that are taken, usually by implication, in different ways, it may help the choice of appropriate method for each type of problems occurring during the development of information systems and can also help to understand the genesis of the different philosophical development techniques. Keywords: engineering requirements, validation, conceptual diagram, Method formal Form enterprise information.

Summary: Beating some of the obstacles to make the Semantic Web a reality has motivated this thesis, which addresses three key themes. Firstly, it introduces a methodology for the extraction of bodies ontological complex texts (and web documents) based on the information provided by ontologies domain. Secondly, it formalizes a multidimensional model that allows use in instances ontological analysis processes such as those proposed in the model data stores, and describes a mechanism to infer multidimensional interesting patterns. Finally, it is the problem of analyzing the information contained in web pages or in a collection of papers on topics of general or domain on which it is impractical to extract and analyze instances ontological by the methods previously proposed. Instead, it is proposed to use text mining techniques and lexical resources to rebuild external conceptual multidimensional spaces that allow analysis of such collections. All proposed solutions obtained satisfactory results.
