Title

Effective retrieval in hospital information systems : the use of context in answering queries to patient discharge summaries

Abstract

Adequate information retrieval in electronic storage of medical records in hospital information systems will have to rely on the exploitation of the conceptual knowledge in those records rather than superficial string searches. This course of action is dependent on the development of natural language processing techniques and on retrieval systems that can exploit semantic/conceptual knowledge. Presents a retrieval system CONIR which attempts to realise the second of these developments which operates in the domain of patient discharge summaries on coronary illness. CONIR uses flexible retrieval techniques, that exploit conceptual context information, over a database of elaborated semantic records. Outlines the sorts of knowledge structures that are required to do this type of retrieval and indicate how they are constructed
