TRIAL: AN INFORMATION RETRIEVAL SYSTEM FOR CREATING, MAINTAINING, INDEXING, AND RETRIEVING FROM FILES OF TEXTUAL INFORMATION-USER'S MANUAL

Abstract

TRIAL is an information processing system that will perform editing, indexing, and retrieval of textual and certain types of numeric information. The system allows for the creation and maintenance of a master file (EDIT), indexing on words designated as 'key' words or, alternatively, on every word in the text, excluding those common terms that are user supplied as a 'stop' word list (INDEX), and computer retrieval and printout of entries that satisfy a user search command (SEARCH). The system is designed such that any one or any combination of the above features can be achieved through one computer run with proper control cards. The system is especially adaptable to large masses of bibliographic data where either selective bibliographies or various forms of indexes are desired.
