Discusses traditional information retrieval through indexing terms and describes a document storage and retrieval system based on structured information, where the SGML document is transformed into Grove (Graph Representation of Property Values) and stored at an element level by an object-oriented database management system. Also discusses query…

Explains how libraries can use data mining techniques for more effective data collection. Highlights include three phases: data selection and acquisition; data preparation and processing, including a discussion of the use of XML (extensible markup language); and data interpretation and integration, including database management systems. (LRW)

Describes a project whose purpose is to set up a computerized database of bilingual texts to be used by researchers in the field of language interaction (i.e., codeswitching, borrowing, and other outcomes of contact between varieties). Current work includes adaptation of the CHILDES system to take account of the different needs of researchers in…

Examines basic issues of data mining using the theory of rough sets, a recent proposal for generalizing classical set theory. Demonstrates that a generalized rough set model can be used for generating rules from incomplete databases. Discusses the importance of rule extraction from incomplete databases in data mining. (AEF)

Describes a bottom-up procedure for discovering multivalued dependencies in observed data without knowing a priori the relationships among the attributes. The proposed algorithm is an application of technique designed for learning conditional independencies in probabilistic reasoning; a prototype system for automated database schema design has…

The Cochrane Collaboration is an international project to locate, review, and disseminate information on available randomized controlled trials of health care interventions. Occupational therapists can use it to learn about best practices and evaluate research relevant to their clients. (SK)

Image processing technology allows libraries to include photographs, paintings, monograph title pages, and maps in their databases. This article examines problems of and solutions to image indexing and retrieval, focusing on thesaurus-based indexing systems, visual thesauri and related hybrid systems, picture description languages, and image…

Reviews two guides on the Child Language Data Exchange (CHILDES) project, both of which provide tools for analyzing talk. (Author/VWL)

Results from a new analysis of synchronous acoustic and fleshpoint-kinematic data, recorded from 53 normal young-adult speakers of American English, are reported. The kinematic data represent speech-related actions of the tongue blade and dorsum, both lips, and the mandible, during the test words, "special" and "problem," and were drawn from an…

Compares/contrasts InfoTrac and ProQuest primarily as full-text resources to supplement retrieval of references contained in the Cumulative Index to Nursing and Allied Health Literature (CINAHL) database. These databases are analyzed by examining their scope in terms of the number and types of serials covered within specific areas using…

Investigates the role of performance limitations in children's early acquisition of verb-argument structure. Tested Valian's (1991) claims that intransitive frames are easier for children to produce early in development than transitive frames, because they do not require a direct object argument. (Author/VWL)

Describes the design of a stemming algorithm for searching Latin text databases. The algorithm uses a longest-match approach with some recoding but differs from most stemmers in its use of two separate suffix dictionaries for processing query and database words that enables users to pursue specific searches for single grammatical forms of words.…

Studies aggressive automated word removal in text categorization in large databases based on corpus statistics to reduce the noise in free texts and to enhance the computational efficiency of categorization. Topics include stop word identification, categorization methods for comparison, tests on four document collections, and evaluation…

Provides acoustic evidence that in the last 50 years New Zealand English (NZE) has undergone a substantial vowel shift. Two sets of data are studied: the Otago corpus, recorded in 1995, and the Mobile Unit Corpus, recorded in 1948. (Author/VWL)

Provides an overview of recent developments relating to the application of thesauri in information organization and retrieval on the World Wide Web. Discusses recent thesaurus projects; types of thesauri on the Web; thesauri integrated within databases and information retrieval systems; multiple thesaurus systems; standards for electronic…
