Abstract

Human indexing for information retrieval is intellectually labor intensive. It requires maintaining a system of indexing rules and policies, which in turn require maintaining a controlled indexing vocabulary. These activities are being performed at the National Library of Medicine in support of indexing the MEDLINE database using the MeSH thesaurus. An additional requirement of the conventional indexing operation is maintaining and developing a user interface, known as the Automated Indexing and Management System (AIMS). Describes knowledge-based indexing, based on a unique prototype, called MedIndEx (Medical Indexing Expert)
