Presents entirely automatic methods for gathering documents for a hypertext, for linking the set, and for annotating those connections with a description of the type (that is, the nature) of the link. Document linking is based on information retrieval similarity measures with adjustable levels of strictness. Evaluation problems are also…

Because 825,000 Internet domain names are assigned and 85,000 new site names are registered each month, the availability of new names is limited. To ease the situation, seven new generic top-level domain names (gTLDs) have been proposed for the Internet's domain name system by the International Ad Hoc Committee established by the Internet Assigned…

Four-, 6-, and 8-year olds were shown a test picture of three related objects and two target pictures of three objects in the same or different relation. Older subjects, but not 4-year olds, identified the relationally similar target picture when the test and target also differed in dimensions of size or color saturation and in direction of size…

Describes differing concepts of nature held by systematists from 1789-1859, connections between these concepts, and how they saw relationships among groups and made classifications. Discusses what these systematists intended their classifications to represent and how these intentions relate to classifications used by twentieth-century biologists.…

Adult students in 4 groups (24 reading disabled, 5 math disabled, 4 reading and math disabled, and 60 nondisabled) completed 2 screening batteries: (1) Wide Range Achievement Test (WRAT) and Barona Premorbid Intelligence Index and (2) WRAT and Kaufman Brief Intelligence Test. Resulting classifications correctly identified approximately 80% as…

Discusses link metrics which show that the hyperlink structure of national university systems can be strongly related to the research productivity of the individual institutions. Uses a page classification on United Kingdom universities to produce even stronger associations, and gives correlations between research productivity and link counts.…

Discussion of knowledge management for electronic data focuses on creating a high quality similarity ranking algorithm. Topics include similarity ranking and unstructured data management; searching, categorization, and summarization of documents; query evaluation; considering sentences in addition to keywords; and vector models. (LRW)

Describes a research project that studied the indexing of moving image collections for storage and retrieval. Highlights include techniques and tools used for representing the content of moving image collections that are indexed shot by shot; indexing languages used, including keywords, classification; thesauri, and subject headings; and lexical…

Discusses scientometric indicators and the strategic value of measurement results using scientometric indicators. Focuses on whether the inclusion of new journals in the "Science Citation Index" can be used for the indication of structural change in the database, and how this change can be compared with reorganizations of relations among…

Using the Rasch model for ordered categories, this paper provides a method for qualitative interpretations of data from an affective measure such as an attitude scale. This maximum information approach provides explicit qualitative information about the meaning of a score on the latent trait being assessed. (SLD)

Investigated the impact of categorization on confirmatory factor analysis parameter estimates, standard errors, and five ad hoc fit indexes through simulation studies. Results replicate some previous studies but also suggest that tests of parameter estimates will be underestimated and the amount of underestimation will increase as saturation…

Studied whether the characteristics of the optimal categorization identified by Rasch analysis in a previous study could be maintained when the revised scale was applied to the same population (206 members of the original adult sample). Overall, the Rasch model fit well, and similar change patterns were observed in two category statistics provided…

Details a study on 10 French native speaking Williams syndrome (WS) individuals in which gender agreement and assignment were assessed through gender categorization and gender concord. Concludes WS people were not impaired in gender agreement which in the French language relies on syntactic rules or on the extraction of regularities, but…

The role of equivalence class formation in delayed position recognition span performance was examined with three mentally retarded adults. Matching-to-sample training established equivalence classes. In subsequent span tests, subject-produced numeral names led to dramatic increases in span scores. The equivalences provided precursors of verbal…

Describes the work by Silvio Ceccato regarding machine translation systems and procedures, exploring such aspects of his work as functional philosophical approaches to machine translation, notional spheres, correlational analysis, and type classifications. Ceccato envisioned many of the methods that are now being applied in machine translation…
