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)

Evaluation of e-learning web sites using fuzzy axiomatic design based approach
High quality web site has been generally recognized as a critical enabler to conduct online business. Numerous studies exist in the literature to measure the business performance in relation to web site quality. In this paper, an axiomatic design based approach for fuzzy group decision making is adopted to evaluate the quality of e-learning web sites. Another multi-criteria decision making technique, namely fuzzy TOPSIS, is applied in order to validate the outcome. The methodology proposed in this paper has the advantage of incorporating requirements and enabling reductions in the problem size, as compared to fuzzy TOPSIS. A case study focusing on Turkish e-learning websites is presented, and based on the empirical findings, managerial implications and recommendations for future research are offered
A Linguistic Recommender System For University Digital Libraries To Help Users In Their Research Resources Accesses
The Web is one of the most important information media and it is influencing in the development of other media, as for example, newspapers, journals, books, libraries, etc. Moreover, in recent days people want to communicate and collaborate. So, libraries must develop services for connecting people together in information environments. Then, the library staff needs automatic techniques to facilitate that a great number of users can access to a great number of resources. Recommender systems are tools whose objective is to evaluate and filter the great amount of information available on the Web. We present a model of a fuzzy linguistic recommender system to help University Digital Library users in their research resources accesses. This system recommends researchers specialized and complementary resources in order to discover collaboration possibilities to form multi-disciplinaryy groups. In this way, this system increases social collaboration possibilities in a university framework and contributes to improve the services provided by a University Digital Library
Integrating Quality Criteria in a Fuzzy Linguistic Recommender System for Digital Libraries
Recommender systems can be used in an academic environment to assist users in their decision making processes to find relevant information. In the literature we can find proposals based in userâ profile or in itemâ profile, however they do not take into account the quality of items. In this work we propose the combination of itemâ relevance for a user with its quality in order to generate more profitable and accurate recommendations. The system measures item quality and takes it into account as new factor in the recommendation process. We have developed the system adopting a fuzzy linguistic approach.Projects TIN2010-17876, TIC5299 y TIC-599
URBANO: A Tour-Guide Robot Learning to Make Better Speeches
âThanks to the numerous attempts that are being made to develop autonomous robots, increasingly intelligent and cognitive skills are allowed. This paper proposes an automatic presentation generator for a robot guide, which is considered one more cognitive skill. The presentations are made up of groups of paragraphs. The selection of the best paragraphs is based on a semantic understanding of the characteristics of the paragraphs, on the restrictions defined for the presentation and by the quality criteria appropriate for a public presentation. This work is part of the ROBONAUTA project of the Intelligent Control Research Group at the Universidad PolitĂ©cnica de Madrid to create "awareness" in a robot guide. The software developed in the project has been verified on the tour-guide robot Urbano. The most important aspect of this proposal is that the design uses learning as the means to optimize the quality of the presentations. To achieve this goal, the system has to perform the optimized decision making, in different phases. The modeling of the quality index of the presentation is made using fuzzy logic and it represents the beliefs of the robot about what is good, bad, or indifferent about a presentation. This fuzzy system is used to select the most appropriate group of paragraphs for a presentation. The beliefs of the robot continue to evolving in order to coincide with the opinions of the public. It uses a genetic algorithm for the evolution of the rules. With this tool, the tour guide-robot shows the presentation, which satisfies the objectives and restrictions, and automatically it identifies the best paragraphs in order to find the most suitable set of contents for every public profil
Proceedings of the 15th Conference on Knowledge Organization WissOrg'17 of theGerman Chapter of the International Society for Knowledge Organization (ISKO),30th November - 1st December 2017, Freie UniversitÀt Berlin
Wissensorganisation is the name of a series of biennial conferences /
workshops with a long tradition, organized by the German chapter of the
International Society of Knowledge Organization (ISKO). The 15th conference in
this series, held at Freie UniversitÀt Berlin, focused on knowledge
organization for the digital humanities. Structuring, and interacting with,
large data collections has become a major issue in the digital humanities. In
these proceedings, various aspects of knowledge organization in the digital
humanities are discussed, and the authors of the papers show how projects in
the digital humanities deal with knowledge organization.Wissensorganisation ist der Name einer Konferenzreihe mit einer langjÀhrigen
Tradition, die von der Deutschen Sektion der International Society of
Knowledge Organization (ISKO) organisiert wird. Die 15. Konferenz dieser
Reihe, die an der Freien UniversitÀt Berlin stattfand, hatte ihren Schwerpunkt
im Bereich Wissensorganisation und Digital Humanities. Die Strukturierung von
und die Interaktion mit groĂen Datenmengen ist ein zentrales Thema in den
Digital Humanities. In diesem Konferenzband werden verschiedene Aspekte der
Wissensorganisation in den Digital Humanities diskutiert, und die Autoren der
einzelnen BeitrÀge zeigen, wie die Digital Humanities mit Wissensorganisation
umgehen
Language-based multimedia information retrieval
This paper describes various methods and approaches for language-based multimedia information retrieval, which have been developed in the projects POP-EYE and OLIVE and which will be developed further in the MUMIS project. All of these project aim at supporting automated indexing of video material by use of human language technologies. Thus, in contrast to image or sound-based retrieval methods, where both the query language and the indexing methods build on non-linguistic data, these methods attempt to exploit advanced text retrieval technologies for the retrieval of non-textual material. While POP-EYE was building on subtitles or captions as the prime language key for disclosing video fragments, OLIVE is making use of speech recognition to automatically derive transcriptions of the sound tracks, generating time-coded linguistic elements which then serve as the basis for text-based retrieval functionality
