Describes an information retrieval system in which advanced natural language processing is used to enhance the effectiveness of term-based document retrieval by preprocessing the documents; discovering interterm dependencies and build a conceptual hierarchy specific to database domain; and processing the user's natural language requests into…

The Latent Semantic Indexing and MatchPlus systems examine similar contexts in which words appear and create representational models that capture the similarity of meaning of terms and then use the representation for retrieval. Text Retrieval Conference experiments using these systems demonstrate the computational feasibility of using…

Intelligence-related differences in perceptual processing in a global/local task were studied for 19 mentally retarded high school students and 19 nonretarded college students. Both groups processed global information faster than local information, and local naming practice caused increases in local processing time. (SLD)

Explores administrators' basic modes of information processing: relating to and recalling information without considering implications; relating to information according to practical implications; posing critical questions about information's validity; and relating to information according to fundamental principles. Administrators have different…

A decision support system integrates individuals' intellectual resources with computer capabilities to improve decision-making quality. This paper presents the theoretical aspects of decision making and decision support and shows how the theories can be applied in developing an operational management decision-making support system for room booking…

Describes new information processing developments and end-user products from 18 companies. Applications include optical storage and imaging devices, document management software, and automated business and data processing systems. Developments include flat-screen images, affordable image item processing, digital writing technology, and a federal…

In two experiments, children and adults were exposed to four different information-processing tasks to measure speed and variability of performance across different age groups. It was found that 10- and 11-year-olds were about 1.7 and 1.6 times slower than 19-year-olds, differences that were not affected by allowing both groups practice on the…

Applies theories about organizational information processing to better understand the influences on method of access and on effects of using online information. Explores the extent to which organizational differences also influence these variables, what the positive and negative outcomes from using online commercial databases are, and how those…

Describes shortcomings of computer science/engineering education and explains a new focus on informatics. Highlights include simulation, visualization, algorithmization, design of information processing models, parallel computing, a history of informatics, informatics versus physics and mathematics, and implications for education. (51 references)…

This paper presents a neuropsychosocial model of information processing to explain a victimization experience, specifically child sexual abuse. It surveys the relation of sensation, perception, and cognition as a systematic way to provide a framework for studying human behavior and describing human response to traumatic events. (Author/JDD)

In 1982, a National Association of Secondary School Principals (NASSP) task force began to construct a learning style paradigm and develop a psychometrically sound assessment instrument. The NASSP paradigm evolved from three precursors: personality theory, the information processing aspect of cognitive style research, and aptitude-treatment…

A study of simple reaction time (SRT) and choice reaction time (CRT) in 71 Chicano adolescents suggests that Hick's model is appropriate for studying cognitive information processing in Chicanos. No age or sex differences were found for SRT or CRT, although there were some differences in SRT by family income level. (KS)

Focuses on synthesis in research--the combination of thesis and antithesis in the dialectical process, producing a new and higher form of being. Discusses kinds of synthesis (unique communication, plan of operation, abstract relations); synthesizing information pieces; summary practice leading to synthesis; and questions of analysis and synthesis.…

Discusses possibilities and dangers involved with using hypertext for learning; explains how it is similar to and different from other forms of information generation, organization, storage, and retrieval; examines its influence on the information it organizes; and explores problematic issues (including the potential for bias and distortion within…

Discusses the use of Web logs to record student behavior that can assist teachers in assessing performance and making curriculum decisions for distance learning students who are using Web-based learning systems. Adopts decision tree and data cube information processing methodologies for developing more effective pedagogical strategies. (LRW)
