Online services (OLS) provide billions of Internet users with a variety of opportunities to exchange goods, share information, and develop or maintain relationships. Popular examples of OLS web sites include eBay.com, Amazon.com, Dell.com, Craigslist.com, MSN.com, Yahoo.com, LinkedIn.com, Zillow.com, Facebook.com, Wikipedia.com, and Twitter.com.…

Computer based information search services, ISS's, of the type that provide on-line literature searches are analyzed from a system's viewpoint using a continuous simulation model. The analysis shows that the observed growth and stagnation of a typical ISS can be explained as a natural consequence of market responses to the service together with a…

Discussion of standards and protocols (set of rules by which two computers or other electronic devices can exchange data for same purpose) highlights history of standards and their interaction with the design and evolution of real computer networks. Topics noted include reference models; conformance, compatibility, and interoperability; and…

Discusses the need for standards allowing computer-to-computer communication and gives examples of technical issues. The seven-layer framework of the Open Systems Interconnection (OSI) Reference Model is explained and illustrated. Sidebars feature public data networks and Recommendation X.25, OSI standards, OSI layer functions, and a glossary.…

Considers a study of two models of name/title-derived search keys in a large online library network. Results predicted by the models are compared with results obtained from actual retrieval behavior of keys entered by users of the system. (FM)

Presents a model that distinguishes between data as directly observable facts, information as structured collections of data, and knowledge as methods of using information. The discussion covers the likely benefits of the use of the model for a semantic information retrieval system using the concept of semantic categories. (28 references)…

This paper describes an information system for managerial decision making which attempts to satisfy the data requirements of all 12 mental health comprehensive services. The essential characteristics of an on-line computer information system are presented with the emphasis upon the use of the system by directors and managers for program planning,…

This discussion of methods for selecting an integrated, public-access library system highlights the traditional idealized selection model; participation by the library director, consultant, task force, committees, and vendors; fads and cost figures; selection of the wrong system; and suggestions for an informal approach to purchasing. Five sources…

Examines various ways of dividing the labor of an information search between the person and the system. Different configurations of two dimensions--degree of system involvement in searching and types of search activity carried out by the person or system--are discussed. Recommendations for further research and development are offered. (49…

This paper discusses the role of XML in library information systems at three major levels: as are presentation language that enables the transport of bibliographic data in a way that is technologically independent and universally understood across systems and domains; as a language that enables the specification of complex validation rules…

Integration of an intelligent gateway system with a commercial, online library support system to produce an integrated bibliographic information system is undergoing prototype testing for the Department of Defense libraries. The objective is to create an integrated system to promote resource sharing in a distributed environment. Five sources are…

The 31 papers in this proceedings cover social as well as technical issues, mathematical models and formal logic systems, applications descriptions, program design, cost analysis, and predictions. The papers are grouped into sessions including: privacy and information technology, describing documents, information dissemination systems, public and…

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…

The National Academy of Sciences suggests models for biomedical research which include a biology-wide information system with computerized database accessible from a multitude of dimensions. Links could help discover whether toxic chemicals have effects similar to hormones. Commonalities from molecules to ecosystems might restructure available…

Presents new perspective on computerized information interchange within library community, and explains Open Systems Interconnection Model promoted by International Organization for Standardization, American National Standards Institute, and National Bureau of Standards. The Linked System Project undertaken by Library of Congress, Research…
