Highlights considerations in developing databases of nursing student records. Discusses flat-file and relational databases, planning issues, college information needs, and staff training. (SK)

Discusses methods of evaluating commercial online databases and provides examples that illustrate their hidden dimensions. Topics addressed include size, including the number of records or the number of titles; the number of years covered; and the frequency of updates. Comparisons of Readers' Guide Abstracts and Magazine Article Summaries are…

Examines and reviews the ability of various software packages and database systems to recognize and process chemical structures generated by chemical drawing packages, especially the ability of relational database management systems to recognize and process chemical structures from a variety of sources. The need for better standard representations…

Reviews four key Internet sites that offer environmental health research data, grant programs, environmental education resources, networking, and other environmental information. Provides addresses and brief descriptions of the resources. Discusses methods for making queries. (LZ)

Describes techniques used for information retrieval from free-text or document databases and presents a new approach based on signature files, or representations of documents, called the Map Array Signature (MAS) method. False drops are discussed, and results of experiments are compared to Robert's Superimposed Coding method. (20 references) (LRW)

Explains sublanguages in restricted domains in natural language processing and describes methods of comparing sublanguages through Case Hierarchy representation. Highlights include case grammar representations of natural language; case systems of sublanguages; sublanguage comparisons, including matching relationships and mapping relationships; and…

Reports on the development of an NLP (natural language processing) component for processing the free-text comments on life insurance applications for evaluation by an underwriting expert system. A sublanguage grammar approach with strong reliance on semantic word classes is described. Highlights include lexical analysis, adjacency analysis, and…

Provides guidelines on using two national networks, BITNET and the Internet. The discussion covers electronic mail, bulletin boards, collections of public files, downloading files, logging into remote systems over the Internet, online catalogs and local databases on the Internet, and future applications. (2 references) (MES)

Discussion of networked information retrieval and the interoperability of heterogeneous information-retrieval systems shows how differences concerning search operators and database schemas can be handled by applying data-abstraction concepts in combination with uncertain inference. Highlights include data types, data independence, schema…

Examines a variety of teaching implications in using existing corpora and explores the need to develop additional corpora databases. Discusses how teachers of language have turned to authentic texts to improve the communicative competence of their students and how computer corpora could provide additional sources of authentic texts. (SC)

Describes how a software program for DOS/Windows manages a collection of pictures such as photographic slides, overheads, or computer images in one or more databases. Explains how it transforms image files to raw binary files that can then be displayed like flash cards, or as an animated series of images. (Author/LRW)

Presents a framework that combines Genetic Programming and Inductive Logic Programming, two approaches in data mining, to induce knowledge from noisy databases. The framework is based on a formalism of logic grammars and is implemented as a data mining system called LOGENPRO (Logic Grammar-based Genetic Programming System). (Contains 34…

Discussion of XML (extensible markup language) and the traditional DTD (document type definition) format focuses on efforts of the World Wide Web Consortium's XML schema working group to develop a schema language to replace DTD that will be capable of defining the set of constraints of any possible data resource. (Contains 14 references.) (LRW)

Demonstrates that the substitution of a foreign segment in the borrowing of a database, which includes 14,350 segmental malformations from French and English loanwords in eight distinct languages, involves its replacement by a single native placement. This tendency is without exception, other than in cases where nasal vowels are concerned.…

Introduces a conceptual integration approach to heterogeneous databases or information systems that exploits the similarity in metalevel information and performs metadata mining on database objects to discover a set of concepts that serve as a domain abstraction and provide a conceptual layer above existing legacy systems. Presents results of…
