The exponential growth in the literature of most fields has produced a near crisis situation for the people who provide storage and retrieval facilities for this same literature. One useful tool suggested for anyone interested in mechanizing the process of information storage and retrieval requires that vocabulary used in the system be divided…

Describes WebACE, the architecture of a client-side agent that explores and classifies Web documents in clusters automatically and discusses the details of the algorithms within its key components. Highlights principal direction divisive partitioning (PDDP), a scalable hierarchical clustering algorithm; compares it to other clustering methods; and…

Experiments were performed to determine the feasibility of using ALCAPP as one form of on-line dialogue. Assuming the ALCAPP (Automatic List Classification and Profile Production) system is in an on-line mode, investigations of those parameters which could affect its stability and reliability were conducted. Fifty-two full test documents were used…

Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…

In response to recent trends towards automated bibliographic control, this issue of "Drexel Library Quarterly" discusses present day bibliographic classification schemes and offers some insight into the future. This volume contains essays which: (1) define "classification"; (2) provide historical background; (3) examine the Dewey Decimal System,…
