Well designed thesauri can represent seman-tic/conceptual knowledge so as to reveal relationships among diierent elements in documents, thus serving as a critical tool in intelligent text retrieval systems and document analysis systems. In this paper, we present a thesaurus system, referred to as TheSys, which can be used as a tool for users to build thesauri according to their own requirements...

Bootstrapping semantics from text is one of the greatest challenges in natural language learning. We first define a word similarity measure based on the distributional pattern of words. The similarity measure allows us to construct a thesaurus using a parsed corpus. We then present a new evaluation methodology for the automatically constructed thesaurus. The evaluation results show that the the...

We propose a method for expanding the entries in a thesaurus using a di erent thesaurus constructed with another concept. This method constructs a mapping table between the concept codes of these two di erent thesauri. Then, almost all of the entries of the latter thesaurus are assigned the concept codes of the former thesaurus with the mapping table between them. To con rm whether this method ...

Documentation and retrieval processes at the Netherlands Institute for Sound and Vision are organized around a common thesaurus. To help improve the quality of these processes the thesaurus was transformed into an RDF/OWL ontology and extended on basis of implicit information and external resources. A thesaurus browser web application was designed, implemented and tested on future users.

This paper describes the work done in the TIPS project about the construction of a thesaurus base. This construction is a merge from a thesaurus manually built and one automatically extracted from large text corpora. Several manually built thesaurus have been semiformatted to be merged in a consistent common base. The automatic extraction is based on both syntax and statistics. We present in th...

--This paper describes an attempt to explain various characteristics of Punjabi language. The origin and symbols of Punjabi language are presents in this paper. Various relations exist in thesaurus and role of thesaurus in natural language processing also has been elaborated in this paper. Keywords---Thesaurus, Punjabi, characteristics, relations

Corpus-based thesaurus construction for Morphologically Rich Languages (MRL) is a complex task, due to the morphological variability of MRL. In this paper we explore alternative term representations, complemented by clustering of morphological variants. We introduce a generic algorithmic scheme for thesaurus construction in MRL, and demonstrate the empirical benefit of our methodology for a Heb...

In the paper we present description of Thesaurus on Sociopolitical life, which was constructed as a tool for automatic text processing of large text collections. Specific features of the thesaurus in comparison to conventional information-retrieval thesauri for manual indexing are described. Evaluation of thesaurus-based information retrieval for short queries showed considerable improvement of...
