Explains the concept of a semantic Web where software agents perform jobs for end-users by using hierarchies, metadata, and structured vocabularies. Discusses taxonomies; defining ontologies and taxonomies; standardized language and conceptual relationships; different points of emphasis; and topic maps as new Web infrastructure. (LRW)

Patterns of memory dysfunction were determined in 50 middle school learning disabled readers (LD) through a hierarchical cluster analysis. Results were consistent with memory capacity theories of LD and provided external validation for classification of LD readers on psychometric measures according to patterns of memory performance.

Guidelines are presented for categorizing, documenting, and storing a historical videotape collection. Causes of videotape deterioration are discussed. (Contains three references.) (SLW)

Presents a three-class taxonomy of current approaches to the provision of performance support and suggests that this could form the basis for future developments for electronic performance support. Intrinsic, extrinsic, and external types of performance support are described, and tables outline characteristics of intrinsic and extrinsic…

This paper examines the need for a transcription system that allows the symbolization of nonnormal articulations. The paper then describes transcription systems proposed by clinical phoneticians and speech pathologists, especially PRDS (phonetic representation of disordered speech) symbols and extensions of the International Phonetic Alphabet.…

Lists the classifications of 3,856 institutions of higher education under the Carnegie Foundation's new classification system. Includes text of the category definitions and lists institutions alphabetically by state, with new and, when different, old classifications. (DB)

Presents a multilevel model of the information filtering process that permits document classification. Evaluates a document classification approach based on a supervised learning algorithm, measures the accuracy of the algorithm in a neural network that was trained to classify medical documents on cell biology, and discusses filtering…

Shows how a theorem proven by H. Brogden (1951, 1959) can be used to estimate the allocation average (a predictor based classification of a test battery) assuming that the predictor intercorrelations and validities are known and that the predictor variables have a joint multivariate normal distribution. (SLD)

Presents a morphological classification of languages from the information retrieval (IR) perspective. Discusses differences in inflection, derivation, and compounding; index of synthesis and index of fusion; cross-language retrieval research; the need for semantic and syntactic typologies; and the effects of morphology and stemming in IR.…

Discusses the shift in the organization and classification of knowledge as a result of the World Wide Web and considers implications for the liberal arts and education in the liberal arts. Highlights include the postmodern period and the obsolescence of knowledge hierarchies; and personal meaning schemes. (LRW)

More often than not, metafiction is approached more on philosophical than aesthetic grounds. In metafictional works the ontological or epistemological dimensions of works of art, literature in particular, are being highlighted by the art works themselves. Moreover, metafictional works of art are singled out as a specific type, almost a genre. This…

Course developers can be distracted from applying sound instructional design principles by the amount of flexibility offered through online course development resources (Kidney & Puckett, "Quarterly Review of Distance Education," 4 (2003), 203-212). Distance education course management systems (CMS) provide multiple features that can be easily…

Sometimes the questions that art poses and the paths taken to answer them can be as important as the answers themselves. Questions in aesthetics--the branch of art that deals with philosophical issues--involve exploration of big ideas that have varied and multiple responses. Providing opportunities for students to consider and reflect upon their…

This paper presents a new hierarchical classes model, called Tucker2-HICLAS, for binary three-way three-mode data. As any three-way hierarchical classes model, the Tucker2-HICLAS model includes a representation of the association relation among the three modes and a hierarchical classification of the elements of each mode. A distinctive feature of…

The authors introduce subset conjunction as a classification rule by which an acceptable alternative must satisfy some minimum number of criteria. The rule subsumes conjunctive and disjunctive decision strategies as special cases. Subset conjunction can be represented in a binary-response model, for example, in a logistic regression, using only…
