Researchers that investigate the media's coverage of health have historically relied on keyword searches to retrieve relevant health news coverage, and manual content analysis methods to categorize and score health news text. These methods are problematic. Manual content analysis methods are labor intensive, time consuming, and inherently…

Reviews major term-weighting theories, presents methods for estimating the relevance properties of terms based on their frequency characteristics in a document collection, and compares weighting systems using term relevance properties with more conventional frequency-based methodologies. Eighteen references are cited. (Author/FM)

This study surveyed abstracting policies and guidelines used by producers of bibliographic databases that aim to enhance free-text retrieval. Results indicate editors consider content of abstracts and their language as primary factors in retrieval enhancement. Most recommend that concepts and form be coordinated with controlled vocabulary…

Demonstrates efficiency of preparation of query description using semantic analyser method based on analysis of semantic structure of documents in field of automatic indexing. Results obtained are compared with automatic indexing results performed by traditional methods and results of indexing done by human indexers. Sample terms and codes are…

Discusses the evolution of the Great Comprehensive Electronic Encyclopedia (GCEE) which would contain everything known to humanity and its potential impact on research and education. The question of who should control access to GCEE and indexing, validation, and selection procedures for materials in its data banks are considered. (AM)

Describes research which measured the efficiency of role operators through frequency of appearances in PRECIS input strings for 200 abstracts related to taxation, genetic psychology, and Shakespearian drama. Frequencies of appearance of major categories of role operators, role operators in different subjects, individual main line operators, and…

Examines the developing state of subject access on the Web. Topics include new scholarly research methods; authority control; cataloging and metadata; interoperability and thesauri development; extensibility, including XML and RDF (resource description framework); indexing and information retrieval; flexibility in subject classification; and…

Relative effectiveness of indexing using full-text or less than full-text was tested using non-Boolean, chaining type of file structure and searching method. Indexing was done using titles, abstracts, full-text, references, and various combinations; Goffman's indirect method of information retrieval was used to structure and search file.…

Examination of citations indexed in Social Science Citation Index (SSCI) reveals salient patterns which can be helpful in determining interdisciplinarity and/or disciplinarity. Collection development efforts can be enhanced by examination of citation patterns of published research related to a classical social science author such as Jean-Jacques…

Describes a fast algorithm for comparing the lists of terms representing documents in automatic classification experiments. Complexity and running time for the algorithm are compared to other procedures, and a short algol-like routine is presented in the appendix. Eight references are included. (Author/BK)

Discussion of the information needs and information-seeking behavior of interdisciplinary scholars and students focuses on kinds of research needed at both basic and applied levels. Topics include prior research; the organization, description, and indexing of information in libraries for successful information retrieval; and research techniques in…

Discussion of the information-seeking behavior of humanists focuses on a study that investigated the efficacy of following bibliographic references from documents already known. Topics include the nature of humanities research; vocabulary control and indexing; subject-based literature searches; seed documents; relevance; retrieval based on…

The accelerating rate of data generation and resulting publications are taxing the ability of scientific investigators to stay current with the emerging literature. This problem, acute in science, is not uncommon in other areas. New approaches to managing this explosion of information are needed. While it is only possible to read one paper or…

The Comparative Systems Laboratory (CSL) proposed to deal with the problems of testing retrieval systems by examining a number of processes involved in such systems, with particular attention to the human factor. It is hoped that the results of the project will be useful in refining methodologies for experimentation with information retrieval (IR)…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
