Title: Evaluating the effectiveness of an on-line, natural language retrieval system
Abstract: An evaluation of an on-line retrieval system known as EARS (Epilepsy Abstracts Retrieval System) has been performed. The system, which permits the free text searching of approximately 8000 abstracts drawn from Epilepsy Abstracts, is supported by the National Institute of Neurological Diseases and Stroke (NINDS). Specialists in the field of neurology, at six medical centers in the United States, conducted on-line searches to satisfy their own needs for information. Parallel searches were conducted on the same search topics by a neurologist at NINDS who was highly experienced in using the system. The results of the original searches were evaluated in terms of recall, precision, and general user satisfaction. A detailed analysis of factors affecting the success and failure of the on-line searches was carried out.
