The Use of Extended Boolean Logic in Information Retrieval

Author
Salton, Gerard
Abstract
An extended Boolean retrieval strategy has previously been introduced in which the individual Boolean operators can be treated more or less strictly, depending on the perceived strength of association of the query terms. The extended Boolean system is illustrated by examples and evaluation output is used to demonstrate the effectiveness of the operations.
