Practical enhanced Boolean retrieval: Experiences with the smart and sire systems

摘要

During the last decade, studies with the SMART and SIRE systems have pioneered new techniques for improving the effectiveness of Boolean retrieval. Extended Boolean logic, automatic Boolean query construction, and Boolean feedback yield significant improvements according to a variety of experiments with SMART. Ranking of the output of Boolean queries has been shown to be of value with SIRE.Recent efforts have aimed at adapting SMART to allow large scale testing of these advanced retrieval methods. SIRE has been enhanced to include the p-norm scheme for extended Boolean query processing. Implementation and performance details about SMART and SIRE illustrate how commercially available retrieval systems can be improved to use the fruits of these research efforts.
