A Review on Information Accessing Systems Based on Fuzzy Linguistic Modelling

This paper presents a survey of some fuzzy linguistic information access systems. The review shows information retrieval systems, filtering systems, recommender systems, and web quality evaluation tools, which are based on tools of fuzzy linguistic modelling. The fuzzy linguistic modelling allows us to represent and manage the subjectivity, vagueness and imprecision that is intrinsic and characteristic of the processes of information searching, and, in such a way, the developed systems allow users the access to quality information in a flexible and user-adapted way.European Union (EU) TIN2007-61079 PET2007-0460Ministry of Public Works 90/07Excellence Andalusian Project TIC529

A multi-granular linguistic model to evaluate the suitability of installing an ERP system

The use of Enterprise Resource Planning (ERP) has shown clearly useful and economically profitable in most very large organizations which manage a great deal of data in their information systems. Nevertheless, the decision of installing an ERP system is not easy and it depends on the size, future profits and other features of the companies. The assessments of the parameters (features, aspects) used to evaluate the suitability of the ERP may be vague and imprecise because they are usually perceptions of the experts. We propose the use of linguistic information to assess these parameters due to the fact that it is very suitable to model and manage human perceptions. In addition, it may be that each expert has a different knowledge about each parameter and prefers to express his/her preferences in his/her own linguistic term set. Therefore, to manage the evaluation problem of installing an ERP, in this contribution we present a multi-granular linguistic evaluation model that covers these necessities

Visualization and evolution of the scientific structure of fuzzy sets research in Spain

Introduction. Presents the first bibliometric study on the evolution of the fuzzy sets theory field. It is specially focused on the research carried out by the Spanish comunity. Method. The CoPalRed software, for network analysis, and the co-word analysis technique are used. Analysis. Bibliometric maps showing the main associations among the main concepts in the field are provided for the periods 1965-1993, 1994-1998, 1999-2003 and 2004-2008. Results. The bibliometric maps obtained provide insight into the structure of the fuzzy sets theory research in the Spanish community, visualize the research subfields, and show the existing relationships between those subfields. Furthermore, we compare the Spanish community with other countries (the USA and Canada; the UK and Germany; and Japan and Peoples Republic of China). Conclusions. As a result of the analysis, a complete study of the evolution of the Spanish fuzzy sets community and an analysis of its international importance are presented.Introducción. Presenta el primer estudio bibliométrico sobre la evolución del campo de la teoría de conjuntos difusos. Se centra especialmente en la investigación llevada a cabo por la comunidad española. Método. Se utiliza el software de CoPalRed, para el análisis de red, y la técnica de anñlisis de co-palabras. Aná;lisis. Se proporcionan mapas bibliométricos mostrando las principales asociaciones entre los principales conceptos en el campo para los períodos de 1965-1993, 1994-1998, 1999-2003 y 2004-2008. Resultados. Los mapas bibliométricos obtenidos proporcionan conocimientos sobre la estructura de la investigación sobre teoría de conjuntos difusos en la comunidad española, visualizan los subcampos de investigación y muestran las relaciones existentes entre los subcampos. Ademñs, se compara la comunidad española con otros países (Estados Unidos y Canada; Reino Unido y Alemania; y Japón y República Popular China). Conclusiones. Como resultado de los análisis, se presenta un estudio completo de la evolución de la comunidad española en conjuntos difusos y un anñlisis de su importancia internacional.This work has been supported by the Spanish project FUZZY-LING, Cod.

Histocarto project: Application of GIS tools (georeferencing and geolocation) to improve the retrieval of graphic historical documents

Se presenta el proyecto Histocarto, cuyo objetivo es la creación de un geoportal donde los potenciales usuarios puedan disfrutar, de forma fácil, cómoda e intuitiva, de parte del patrimonio histórico cartográfico y fotográfico de la ciudad de Granada, centrándose principalmente en lo referente a urbanismo y paisaje. La recuperación de este tipo de documentación hoy en día no es efectiva en otras webs institucionales, en perfiles de redes sociales o en webs personales. A través de la metodología adecuada que incluye: localización, selección, digitalización, descripción, georreferenciación (cartografía) y geolocalización (fotografía), teselación y publicación web, se ha obtenido como resultado un geoportal o visualizador cartográfico donde poder hacer búsquedas textuales tradicionales mejoradas con filtros, búsquedas geográficas más intuitivas, comparar el pasado y el presente entre los documentos, y poner en relación unos documentos con otros.The Histocarto project aims to create a geoportal where potential users can enjoy in an easy, comfortable and intuitive way, part of the historical cartographic and photographic heritage of the city of Granada, focusing mainly on urbanism and landscape. The retrieval of this kind of documents nowadays is not effective in other institutional webs, in profiles of social networks or in personal web sites. Through the appropriate methodology that includes: location, selection, digitization, description, georeferencing (cartography) and geolocation (photography), tiling and web publication. As a result we have obtained a geoportal or cartographic visualizer where we can carry out traditional textual searches improved with filters, more intuitive geographic searches, past-present comparison of documents, and link documents.Este trabajo ha sido financiado por la Universidad de Granada, ayuda al Contrato Puente.

A Fuzzy Linguistic Multi-agent Model for Information Gathering on the Web Based on Collaborative Filtering Techniques

Information gathering in Internet is a complex activity. A solution consists in to assist Internet users in their information gathering processes by means of distributed intelligent agents in order to find the fittest information to their information needs. In this paper we describe a fuzzy linguistic multi-agent model that incorporates information filtering techniques in its structure, i.e., a collaborative filtering agent. In such a way, the information filtering possibilities of multi-agent system on the Web are increased and its retrieval results are improve
