COMPUTER INDEXING OF MEDICAL ARTICLES—PROJECT MEDICO

An automatic indexing method is described in which index tags for documents are generated by the computer. The computer scans the text of periodical articles and automatically assigns to them index terms with their respective weights on the basis of explicitly defined text characteristics. A machine file of document references with their associated index terms is automatically produced which can be searched on a co‐ordinate basis for the retrieval of specified drug‐related information.
