Title: An Efficiency Analysis for File Organization and Information Retrieval

Abstract: This study deals with the concept of improving retrieval times and minimizing storage space in an information retrieval system. Three popular information retrieval techniques are examined; the inverted file, the cluster file, and the indirect method.

Index terms are used as a basis for comparing the documents in a document file. The terms form the records in an inverted file, searched in a Boolean manner. The indirect method requires a record for each document; each record contains fields whose values are relative probabilities to all other documents in the file. Document descriptor vectors are constructed and form the records of the cluster file.

Efficiency comparisons are made relative to storage space used and computer retrieval time. A non-multiprogrammed computer was utilized for the final time results. Therefore, the retrieval times are free from operating system overheads.
