Introduces a conceptual integration approach to heterogeneous databases or information systems that exploits the similarity in metalevel information and performs metadata mining on database objects to discover a set of concepts that serve as a domain abstraction and provide a conceptual layer above existing legacy systems. Presents results of…

CITATION INDEXES, IN COMBINATION WITH REGULAR INDEXES, ARE CREATING NEW METHODS OF INFORMATION RETRIEVAL, WHICH USE SOME MEASURE OF CONNECTION OR ASSOCIATION BETWEEN A GIVEN BASE OF ARTICLES AND OTHER DOCUMENTS IN A COLLECTION. GENERAL REQUIREMENTS OF SUCH A MEASURE ARE--(1) IT SHOULD BE INDIRECTLY PROPORTIONAL TO THE NUMBER OF LINKS IN A CHAIN OF…

Discusses problems of matching personal names in information systems and factors influencing design of personal name matching algorithms. Several examples of name matching systems in the fields of art history, bibliography, commerce, genealogy, and law enforcement used for the purposes of authority control, information retrieval, and duplicate…

Virtual scatter storage schemes are well suited dictionaries, having both rapid lookup and economy of storage. (MF)

Addresses the problem of systematic biases which affect the way that individuals construct and modify search queries on online retrieval systems, and suggests a searching algorithm that helps to avoid the effect of those biases. (FM)

This study examined the effectiveness using an automatic algorithm to rank the results of Boolean searches of an inverted file design document retrieval system. Relevant documents were ranked significantly higher than nonrelevant documents on output lists. (Author/KP)

Considers problem of optimal scheduling of Boolean expression (each Boolean variable represents binary outcome of program module) on single-processor system. Optimization discussed consists of finding operand arrangement that minimizes average execution costs representing consumption of resources (elapsed time, main memory, number of…

Surveys the current state of minicomputer-operated information systems capable of incorporating linguistic features, focusing on the Minicomputer Operated Retrieval (Partially Heuristic) System. Consideration is given to the automation of the indexing process and to available search strategies. (FM)

Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document. (VT)

Presents principles for determining profile of a system user based on analysis of co-occurrence of index terms in queries and pertinent documents. A procedure for determining index term weights, the information value of which depends on the degree of homogeneity of system users, is introduced. Three references are cited. (EJS)

This paper deals with quantitative evaluation of the effects of erroneous performance by stemming and similar clustering algorithms in information retrieval systems. (Author)

An information retrieval system which aspires to retrieval of relevant documents should have second stage which will order topical set to provide maximum informativeness to requestor. A two-stage system concerned only with topicality can be iterated to generate a high recall set and discard imprecise documents without user input. (EJS)

Presents a heuristic, attribute-based, noise-tolerant data mining program, HCV (Version 2.0) based on the newly-developed extension matrix approach. Outlines some techniques implemented in the HCV program for noise handling and discretization of continuous domains; an empirical comparison shows that rules generated by HCV are more compact than the…

Large-scale, on-line information storage and retrieval systems pose numerous problems above those encountered by smaller systems. A step toward the solution of these problems is presented along with several demonstrations of feasibility and advantages. The methodology on which this solution is based is that of a posteriori automatic classification…

Describes the simulation of a nearest neighbor searching algorithm for document retrieval using a pool of microprocessors. Three techniques are described which allow parallel searching of a binary search tree as well as a PASCAL-based system, PASSIM, which can simulate these techniques. Fifty-six references are provided.
