Challenging Conventional Assumptions of Automated Information Retrieval with Real Users: Boolean Searching and Batch Retrieval Evaluations.

Peer reviewed

Hersh, William; Turpin, Andrew; Price, Susan; Kraemer, Dale; Olson, Daniel; Chan, Benjamin; Sacherek, Lynetta – Information Processing & Management, 2001

Describes research conducted at the TREC (Text Retrieval Conference) interactive track that compared Boolean and natural language searching, showing they achieved comparable results; and assessed the validity of batch-oriented retrieval evaluations, showing that the results from batch evaluations were not comparable to those obtained in…

Query Evaluation: Strategies and Optimizations.

Peer reviewed

Turtle, Howard; Flood, James – Information Processing & Management, 1995

Discusses two query evaluation strategies used in large text retrieval systems: (1) term-at-a-time; and (2) document-at-a-time. Describes optimization techniques that can reduce query evaluation costs. Presents simulation results that compare the performance of these optimization techniques when applied to natural language query evaluation. (JMV)
