Digital libraries relating to particular subject domains have invested a great deal of human e ort in developing metadata in the form of subject area thesauri. This e ort has emerged more recently in arti cial intelligence as ontologies or knowledge bases which organize particular subject areas. The purpose of subject area thesauri is to provide organization of the subject into logical, semanti...

In our ongoing project we develop a tool which provides domain engineers with a facility to create fuzzy relational thesauri (FRT) describing subject domains. The created fuzzy relational thesauri can be used as knowledge base for an intelligent information agent when answering user queries relevant to the described domains, or for textual searching on the web. However, the manual creation of (...

As audiovisual archives are digitizing their collections and making these collections available online, the need arises to also establish connections between different collections and to allow for cross-collection search and browsing. Structured vocabularies, made available as Linked Data, can be used as connecting points by aligning thesauri from different institutions. In this paper, we prese...

This paper introduces a distributional thesaurus and sense clusters computed on the complete Google Syntactic N-grams, which is extracted from Google Books, a very large corpus of digitized books published between 1520 and 2008. We show that a thesaurus computed on such a large text basis leads to much better results than using smaller corpora like Wikipedia. We also provide distributional thes...

As part of the publication of the AGROVOC thesaurus as Linked Data (LD), AGROVOC is now mapped with six well-known thesauri in the agricultural domain, i.e., EUROVOC, NALT, GEMET, STW, TheSoz, RAMAEU. To find matching candidates, known matching algorithms discussed in the literature and available from public API were used. Results were evaluated by a domain expert, and almost total precision ob...

Various lexical resources are being published in RDF. To enhance the usability of these resources, identical resources in different data sets should be linked. If lexical resources are described in different natural languages, then techniques to deal with multilinguality are required for interlinking. In this paper, we evaluate machine translation for interlinking concepts, i.e., generic entiti...

AUTINDEX is a bilingual automatic indexing system for the two languages German and English. It is being developed within the EU-funded BINDEX project. The aim of the system is to automatically index large quantities of abstracts of scientific and technical papers from several areas of engineering. Automatic indexing takes place using a controlled vocabulary provided in monolingual and bilingual...

The availability of central reference information as thesauri is critical for correct intellectual access to distributed databases, in particular to digital collections in international networks. There is a continuous raise in interest in thesauri, and several thesaurus management systems have appeared on the market. The issue, how to integrate effectively such central resources into a multitud...

User interfaces to information retrieval systems play a major role in assisting users to search, browse and retrieve information relevant to their needs. This paper provides a review of a category of information retrieval interfaces that are enhanced by incorporating standard thesauri as part of their searching and browsing facilities. A brief account of the rationale behind the integration of ...
