An Analysis of Document Retrieval Systems Using a Generalized Model,es, strong points, and inadequacies. The generalized model represents a flexible, comprehensive, modular structure of a retrieval system, as opposed to previous models, which generally emphasize only a specific aspect of the retrieval problem.

Processing Systems Optimization through Automatic Design and Reorganization of Program Modules, as to produce an optimal design with respect to a specific target machine. Performance criteria for the optimal design is defined in terms of four components: (1) processing time, (2) transport volume, (3) core size, and (4) number and type of I/O units required.

Verification and Semantic Checking of APL Programs,rification of programs with arrays. (2) The partial operators introduce the complication of showing program executability. The latter reason leads to a new form of programming, called “semantic checking.”

A Relational Data Management System,RDMS is a flexible data analysis and manipulation system based on Codd’s relational operations and Child’s set-theoretic operations. This presentation focuses on the application of these techniques to practical problems. Some details of our implementation on a large virtual memory computer will be given.

A Data Base Search Problem,The problem of constructing an efficient retrieval algorithm for responding to queries of arbitrary complexity on a relational data base is considered. A query, represented by a relation-defining expression in the relational calculus, is translated into a retrieval algorithm.
