Five experiments examined 15- and 18-month olds' sensitivity to morphosyntactic dependencies. Results indicated that 18-month olds, but not 15-month olds, were sensitive to basic relationship between "is" and "-ing" and that 18-month-olds could track relationships between functor morphemes. Findings were consistent with hypothesis that 18-month…

Considers a "hybrid" approach to the modeling of uncertainty in deductive databases. The model, deductive IST (DIST) is based on an extension of the "Information Source Tracking" (IST) model for relational databases. Proves that the complexity of testing containment of conjunctive DIST queries remains the same as in the…

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…

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,…

Based on action research of the Information Processing (IP) course at the bachelor programme HA/DOK at Copenhagen Business School, we investigate which barriers students experience when learning holistic systems development and why. HA/DOK has been developed to educate students who can facilitate between users and programmers and navigate within…

This paper discusses an innovative blended learning strategy which incorporates online discussion in both in-class face to face, and off-classroom settings. Online discussion in a face to face class is compared with its two counterparts, off-class online discussion as well as in-class, face to face oral discussion, to examine the advantages and…

Research in the development of teacher cognition and teaching performance in K-12 classrooms has identified consistent challenges and patterns of behavior that are congruent with the predictions of dual-process models of cognition. However, cognitive models of information processing are not often used to synthesize these results. This article…
