Abstract

The National Library of Medicine is supporting a research project on full-text search and retrieval. In addition to the research aspect, the project includes a fully deployed system, known as HSTAT, to provide access to health information. The information is all government-supported and includes practice guidelines, reference texts, evidence-based reports, clinical trial information, treatment protocols, and technology assessments. The search system depends on the SGML-encoding of the documents to provide context to the user and supports specific retrieval of pertinent sections or paragraphs of large, complex documents. The retrieval system is an object-oriented client-server model and the data is stored in an object-oriented database management system. This is a probabilistic retrieval system, providing ranked results from a natural language query. It also provides browsing and downloading capabilities, in addition to searching the entire collection or specified documents in the collection. The type of data and the perceived needs of the users have driven the development of the project. The results are measured by observation of participation and usage
