Abstract

New business information services are being launched for network markets and end users. Accuracy will be at premium. Accuracy in information systems is a combination of precision and recall. Discusses the general conditions within which accurary is required. There is a growing awareness of the need to test the accurary of text retrieval tools as evidenced by the Text Retrieval Conference. Discusses the value of accuracy and its cost
