Describes a method for automatically selecting key frames that can be used to represent the total image sequence of visual documents. An abstracting algorithm developed at the National Aeronautics and Space Administration is explained, and extensive examples of abstracted motion sequences are presented. (eight references) (LRW)

Describes research that examined the feasibility of automatically deriving name access points from machine readable title pages of English language monographs. An algorithm for automatic derivation is presented and results using the algorithm are compared to traditionally cataloged name access points. The implications for bibliographic standards…

Reviews the use of signatures to improve the performance of text searching and considers the use of signature trees to further accelerate text searching. Based on the analysis of experimental results, it is concluded that the improvement in text searching performance using signature trees outweighs the increase in required storage. (12 references)…

A founder trustee of OCLC recounts the steps toward automation of library catalogs encountered during his career, from the use of punched cards in a circulation system to the implementation of online union catalogs. (CLB)

Identifies types and distributions of errors in text produced by optical character recognition (OCR) and proposes a process using machine learning techniques to recognize and correct errors in OCR texts. Results of experiments indicating that this strategy can reduce human interaction required for error correction are reported. (25 references)…

Develops mathematical models to characterize the probability of continued use of an integrated office automation system and tests these models on longitudinal data collected from 210 individuals using the IBM Professional Office System (PROFS) at the University of California at Berkeley. Analyses using survival functions and proportional hazard…

Discusses organization design as context for office automation; mature computer-based systems as one application of organization design variables; and emerging office automation systems (organizational information management, personal information management) as another application of these variables. Management information systems models and…

Analyzes the skill acquisition sequence in using a software package and proposes advent models for investigating patterns of user interaction with information systems. The use of transaction log data is explained, advent function analysis is described, and tests of the models on longitudinal data are discussed. (26 references) (LRW)

Describes a method for automatically identifying sublanguage (SL) domain terms and revealing the patterns in which they occur in text. By applying this method to abstracts from a variety of disciplines, differences in how SL domain terminology occurs can be discerned. Findings indicate relatively consistent differences between the hard sciences…

Proposes ways in which computerized data available in public libraries can be organized and used for management decision making. Experiences in the Indianapolis-Marion County Public Library system and the Monroe County (Indiana) Public Library system are described, and use of the data for preparing materials acquisition budgets is discussed. (36…

The SALOMON project automatically summarizes Belgian criminal cases to improve access to existing and future court decisions. This article gives background information about the texts of the cases and describes the output, design models, and architecture of the SALOMON system. Evaluation of 700 criminal cases demonstrates that the algorithms have…

The mathematical model proposed describes a computerized bibliographic information system which includes a method--document learning--of improving the set of index terms assigned to a document representative. Inputs to the information system (index terms and query), relevance feedback, and assumptions concerning the model are discussed.…

Describes a computerized decision support system based on circulation data that was developed to assist the Indianapolis-Marion County Public Library in materials acquisition budgeting and other library management decision making. The budget allocation model is explained, and implementation and testing of the decision support system is described.…

This study tested assumptions about self-sufficiency of academic library collections and the paradigm shift to providing access to information stored elsewhere. Inter-library borrowing statistics of Australian libraries were correlated with collection size. The study concluded that collection self-sufficiency is a fallacy and that the information…
