Explores what might be the optimal query expansion (QE) processing method with semantically coded thesauri. Examines whether QE via semantically coded thesauri terminology is more effective in the "automatic" or "interactive" processing environment. Results revealed that synonyms and partial synonyms and narrower terms are…

Discusses the problems and current research techniques being explored in the area of Cross Language Information Retrieval (CLIR) for finding documents in languages other than the original query. Discusses language identification methods, techniques for automatically generating queries in other languages, and retrieving and merging query results.…

Investigates an automatic method for Cross Language Information Retrieval (CLIR) that utilizes the multilingual Unified Medical Language System (UMLS) Metathesaurus to translate Spanish natural-language queries into English. Results indicate that for Spanish, the UMLS Metathesaurus-based CLIR method is at least equivalent to if not better than…

Uses concept mapping tasks and association tasks to examine knowledge structures about clients. Four experienced and five novice counselors read a counseling transcript, categorized client statements, and mapped the relationships among categories. Results support the information-processing perspective with novice counselors attending to surface…

Experimental results show that a word-based arithmetic-coding scheme, a fractional-bit compression algorithm which is known to be time consuming, can achieve a higher compression performance for Chinese text. This article examines how to cascade the word-segmentation model with a faster alternative, the integral-bit compression algorithm.…

Discusses asserting and assessing authenticity of digital information sources and why authenticity is an issue now. Describes three types of technical and social strategies (public, secret, and functionally dependent) for asserting authenticity. Cites examples of requirements for authenticity from the various stages in the research process. (AEF)

Presents an application of knowledge discovery in texts (KDT) concerning medical records of a psychiatric hospital. The approach helps physicians to extract knowledge about patients and diseases that may be used for epidemiological studies, for training professionals, and to support physicians to diagnose and evaluate diseases. (Author/AEF)

Social information processing theory has been posited as a description of how mental operations affect behavioral responding in social situations. Arsenio and Lemerise (this issue) proposed that consideration of concepts and methods from moral domain models could enhance this description. This paper agrees with their proposition, although it…

Roundhouse is a visually creative information-processing tool (J. E. Trowbridge and J. H. Wandersee 1998). The procedure requires learners to construct knowledge using "mindful" connections to replace less effective practices of memorizing fragmented information. Students create observable organization schemes of related ideas and icons in a…

Metadata is often created in a time-consuming process by catalogers, digital library technicians, and others. It is then underused in the systems. But recent experiments by some library organizations indicate that only the surface is being scratched on what data can do. The American West Project at the California Digital Library (CDL) is…

Valid assessment with diverse populations requires tools that are not influenced by cultural elements. This study investigated the relationships between culture, information processing efficiency, and general cognitive capacities in samples of Caucasian and Mexican American college students. Consistent with the neural efficiency hypothesis,…

Fifteen years ago, Pascual-Leone and colleagues used transcranial magnetic stimulation (TMS) to investigate speech production in pre-surgical epilepsy patients and in doing so, introduced a novel tool into language research. TMS can be used to non-invasively stimulate a specific cortical region and transiently disrupt information processing. These…

This paper presents a research study that explored the nature of the cognitive preferences of school administrators. It offers insight into the school administrators' mode of information processing. The first of three sections concerns the informational centrality of school principals. Citations from the literature are used to present the ways…

A new method of bus route scheduling uses aerial photography and computer data analysis. Maps generated in this manner can be used with other information to study housing/population patterns, attendance boundaries, and the like. (Author/IRT)

Author analyzed the cognitive systems of different peoples and suggested that having diverse means of acquiring information increased the chances that a culture and its institutions would survive. (Editor/RK)
