- Abstract
- An important aspect of information retrieval systems is domain independence, where the subject of the information is not restricted to certain domains of knowledge. This should be able to represent any topic and although the text representation does not involve any semantic knowledge, lexical and syntactic analysis of the text allows the representation to remain domain independent. Reports research at Dublin City University, Ireland, which concentrates on the lexical and syntactic levels of natural language analysis and describes a domain independent automatic information retrieval system which accesses a very large database of newspaper text from the Wall Street Journal. The system represents the text in the form of syntax trees, and these trees are used in the matching process. Reports early results from the stuyd
