The objective of this article is to analyze the searching and indexing techniques of educational search engines' implementation while treating future challenges. Educational search engines could greatly help in the effectiveness of e-learning if used correctly. However, these engines have several gaps which influence the performance of e-learning…

Vocabularies are linguistic resources that make it possible to access knowledge through words. They can constitute a mechanism to identify, describe, explore, and access all the digital resources with informational content pertaining to a specific knowledge domain. In this regard, they play a key role as systems for the representation and…

Searches for 117 British authors are compared in the Annual Bibliography of English Language and Literature (ABELL) and the Modern Language Association International Bibliography (MLAIB).

Distinguishes between document-oriented and user-oriented indexing and discusses the advantages and disadvantages of request-oriented and automated indexing. Request-oriented indexing is difficult to implement with human, a priori indexing. Automated indexing can be tailored to individual requests, but most research in this area focuses on global…

Examines current activities in subject analysis of large bibliographic databases to assist database managers in making cost-effective decisions. Issues addressed include manual indexing aids, automatic indexing, and connecting indexing terms. Several software packages are described, and future research directions are suggested. (58 references)…

Discusses theoretical considerations of indexing as a part of information retrieval theory. Topics discussed include mentalist proposals; text representation and knowledge representation; rules of grammar and syntax; linguistic theory; philosophical theories of Wittgenstein regarding rules; retrieval practices; and the formation of rules in…

Describes recent attempts to make explicit connections between the indexing process and the use of the index or information retrieval system, particularly the utility-theoretic and automatic indexing models of William Cooper and Stephen Harter. Theory and performance, information storage and retrieval, search stage feedback, and indexing are also…

Discusses ambiguities in the terminology used for information retrieval in counseling and related fields, including disagreements over which terms to use, meanings of terms, and relationships between terms.

Briefly reviews early work in documentation and text processing, and predictions that were made about the creative role of computers in information retrieval. An attempt is made to explain why these predictions were not fulfilled and conclusions are drawn regarding the limits of computer power in text retrieval applications. (Author/CLB)

Surveys the current state of minicomputer-operated information systems capable of incorporating linguistic features, focusing on the Minicomputer Operated Retrieval (Partially Heuristic) System. Consideration is given to the automation of the indexing process and to available search strategies. (FM)

Presents a literature review that covers the following topics related to Latent Semantic Analysis (LSA): (1) LSA overview; (2) applications of LSA, including information retrieval (IR), information filtering, cross-language retrieval, and other IR-related LSA applications; (3) modeling human memory, including the relationship of LSA to other…

Presents a literature review that covers the following topics related to indexing, browsing, and searching of digital video: video coding and standards; conventional approaches to accessing digital video; automatically structuring and indexing digital video; searching, browsing, and summarization; measurement and evaluation of the effectiveness of…

Reviews the development of secondary information services in the arts and humanities, discusses the services currently provided and the usage levels for those services, outlines some of the problems associated with online databases in the humanities, and considers some probable future developments. A 5-item reference list is included. (JL)

Views automatic indexing as a two-tiered word frequency analysis that involves selection of a technical vocabulary and identification of document keywords. Assumptions, criteria, evaluation, and relevance are discussed. (JD)
