PHRASE DICTIONARY CONSTRUCTION METHODS FOR THE R2 INFORMATION RETRIEVAL SYSTEM
Abstract
The R2 Information Retrieval System, when complete, will be a question-answer information retrieval system in which a person, having questions over a pre-determined data base, will be able to receive answers to his questions. The paper concerns the initial processing of the data base for the R2 system and explores initially several simple strategies for retrieving relevant statements, rather than answers, for a given question over the data base. The paper is first concerned with the construction of a 'phase dictionary' from the data base, and, secondly, with the development of several initial attempts for information retrieval from the data base.
