The process of building and maintaining thesauri, especially in corporate settings, quite often cannot be justified due to its unfavourable cost-benefit ratio. Combining different approaches to build thesauri like text-mining, machine learning, expert driven thesaurus modelling and linking open data seems to be a promising methodology to overcome this obstacle. This paper gives an overview over...

In this paper, we are interested here in paper enrichment of a thesaurus using a terminology extracted from a dictionary. The thesaurus is structured and the terminology brings definitions. The merger of both resources in an onto-terminology is intended to contribute to the semantic tagging of texts of speciality. We examine the difficulties related to structuring of a terminology in an onto-te...

The paper describes representation and use of variable and nontypical relations of concepts in the Sociopolitical thesaurus constructed specially as a tool for automatic text processing. The variable and non-typical conceptual relations are described in the simplest way by marking of relations by modifiers. The simplicity of notation facilitates representation of such relations for large number...

We advance a method of thesaurus enrichment, based on the extraction coordinations in domain-related corpus. Our hypothesis is that there semantic homogeneity between conjuncts located coordination. conducted an experiment allowed us to evaluate effectiveness our method. This aims enrich concept hierarchy French agricultural named Crop Usage (FCU), thanks texts Plant Health Bulletins (PHB). The...

This paper revisits the lattice-based thesaurus models which Margaret Masterman used for machine translation in the 1950’s and 60’s. Masterman’s notions are mapped onto modern, Formal Concept Analysis (FCA) terminology and three of her thesaurus algorithms are formalised with FCA methods. The impact of the historical and social situatedness of Roget’s Thesaurus on such algorithms is considered....

What is a thesaurus and what is its purpose? Describing the functions of a thesaurus in a nutshell will provide the background for a critical examination of the AAT. A thesaurus is a structured collection of concepts and terms for the purpose of improving the retrieval of information. A thesaurus should help the searcher to find good search terms, whether they be descriptors from a controlled v...
