Three experiments investigated how people organize data. Subjects were given sets of 15-20 words and asked to organize them on paper. Each word set had a pre-defined organization (hierarchy, network, lists, table) based on the semantic relations among the words. Experiment 1 showed that college students have all these organizational structures available for use. They organized most word sets on the basis of the semantic relations inherent in them. Whereas most subjects used “appropriate” organizations (those that most easily preserved the relations), a few subjects organized nearly all word sets into lists. Experiment 2 showed that subjects can efficiently fit the word sets into “skeletons” that were explicitly designed to maintain all the semantic relations among the words. Experiment 3 showed that subjects have difficulty in preserving the relations among the words when they were required to organize them into inappropriate structures. These results are evaluated relative to the use of computer-based information retrieval systems.

Online catalogs are types of interactive computer systems; they can also be called “interactive catalogs” because a user interacts with the computer to find relevant information. The interaction is the main difference between Online Public Access Catalogs (OPACs) and other types of library catalogs (Hildreth, 1982; Matthews, 1985). Online catalogs are regarded as real-time interactive retrieval systems for libraries (Fayen, 1983). According to Peters (1991), the development of online catalogs can be characterized by three decades of development. In the 1960s, the development of online catalogs was led by the development of computer technology and the library community’s desire to increase efficiency in finding library materials. In the 1970s, commercial vendors started to replace large university libraries as the principal developers of computer-based library systems. In the 1980s, local libraries expand their control of the library catalog systems.

It is important that the modern-day researcher and engineer stay abreast of technology in his field, but this task is made very difficult by the recent flood of scientific and technical information. Coping with the information explosion requires the use of computerized information systems. This paper reviews computer-based information retrieval systems in engineering and focuses specifically on databases of literature and information relevant to tribologists and lubrication engineers. These databases are listed and their characteristics are discussed. Results of a sample computer-based literature search are included. It is shown that no single database has complete coverage of all aspects of tribology and that several databases should be searched to get all available information on a subject.

Rapid advances in the computer industry and the concomitant knowledge explosion have created a revolution in the information handling electronics industry. The continued proliferation of computer technology in the educational environment appears inevitable. There seems to be little doubt that recent advances in educational technology will have important consequences for educational institutions at all levels during the coming decades. Students, teachers, and administrators alike have already come to rely on bibliographic and statistical data bases, automated dictionaries, micrographic storage and retrieval systems, and specialized interactive cable and videotext systems for information access. Despite the impact of computer technology in the school environment, guidelines for planning and developing useable software for assessing cognitive abilities has warranted little attention in educational literature. This article suggests that computer-based support systems are now available which could be instrumental in solving the problems associated with cognitive assessment.

This paper presents the first definition of a methodology to analyze, design and evaluate information retrieval systems. We do not address the search engines themselves, but we discuss the computer human interaction implied. We show the need to introduce the user point-of-view in each interaction, and demonstrate the usage of trade oriented knowledge. We argue that, despite the inherent quality of the search engine, the human interface should be considered as the critical part of any system. Information Search Processes must evolve to include a computer-human interaction approach.
