A contribution to indexing in legal information retrieval

Ongoing research in information retrieval offers new approaches, demonstrating that the traditional methods may have reached their limitations. In fact, actual results to date have shown that advanced systems will demonstrate effectiveness at combining multiple text and user need representations. The paper suggests supplementing the traditional conceptual abstracts with a syntactical description designed to improve retrieval performance. This choice is carefully motivated and examples are given. Without attempting to reason about the document contents, a domain specific knowledge representation is used to form clusters of concepts. The point is to represent the joint structure of the component concepts involved in a composite concept. This approach extends the reach of key concept assignment to: interactive query elicitation; multiword phrase search; finer grained thesaurus relationships. The paper emphasizes that intellectual assignment of features is part of an artificial intelligence approach to information retrieval. The principles of implementation are also described
