- Abstract
- Thesaural relations have long been used in information retrieval to enrich queries; they have sometimes been used to cluster documents as well. Sometimes the first query to an information retrieval system yields no results at all, or, what can be even more disconcerting, many thousands of hits. One solution is to rephrase the query, improving the choice of query terms by using related terms of different types. A collection of related terms is often called a thesaurus. This chapter describes the lexical-semantic relations that have been used in building thesauri and summarizes some of the effects of using these relational thesauri in information retrieval experiments

- Abstract
- This experiment, focused on the users behaviour, aims to study the search topic representation they build and to highlight the role of a graphical thesaurus on their mental models and searching behaviour. The users expertise in the field is considered. The results show how difficult it is to structure a field; they also point out how much a graphical thesaurus could contribute to such a task, but also its restricted role in the query task. They urge us to think over which shape is proper to the conceptual interface and the variety of links that have to be taken into account

- Abstract
- Automatic identification of semantic relations in text is a difficult problem, but is important for many applications. It has been used for relation matching in information retrieval to retrieve documents that contain not only the concepts but also the relations between concepts specified in the user's query. It is an integral part of information extraction-extracting from natural language text, facts or pieces of information related to a particular event or topic. Other potential applications are in the construction of relational thesauri (semantic networks of related concepts) and other kinds of knowledge bases, and in natural language processing applications such as machine translation and computer comprehension of text. This chapter examines the main methods used for identifying semantic relations automatically and their application in information retrieval and information extraction.
