A study of 24 scientific articles in the South African Computer Journal compared four term-weighting schemes for detecting information-rich passages in texts. Results demonstrated that word categories and frequency-derived weights were closely correlated but that weighting according to first mention theory (cue-method) and frequency-based weights…

Discussion of the study of interactive information retrieval (IR) at the Text Retrieval Conferences (TREC) focuses on summaries of the Interactive Track at each conference. Describes evolution of the track, which has changed from comparing human-machine systems with fully automatic systems to comparing interactive systems that focus on the search…

Compares a user-defined passage feedback system to a document feedback system for information retrieval, based on TREC (Text Retrieval Conference) guidelines. Highlights include a description of IRIS, an interactive retrieval system; text processing; ranking; term weights; feedback models, including the adaptive linear model; and suggestions for…

Provides directions for developing search strategies to be used on the World Wide Web and with gopher on the Internet. (JOW)

Summarizes a presentation that discussed findings and implications of research projects using an Internet search service and Internet-accessible vendor databases, representing the two sides of public database searching: query formulation and resource utilization. Presenters included: Tefko Saracevic, Amanda Spink, Dietmar Wolfram and Hong Xie.…

Presents an abstract for a planned session on historical perspectives on encyclopedism, from 17th century initiatives to modern thought. Presentations include: "Concepts of Encyclopedia and the Organisation and Retrieval of Knowledge: Historical Perspectives" (W. Boyd Rayward); "Encyclopedism at the End of Modernity" (Mikel…

Discusses the growing gap between what is available on the Internet and what search engines can retrieve, particularly data lost in the breach of the unindexable, versus the unindexed, Web. Highlights include products designed to focus on content that is usually missed by search engines; and directories versus search engines. (Contains 10…

The link between classification and knowledge is explored. The strengths and limitations of four classificatory approaches (hierarchies, trees, paradigms, and faceted analysis) are described in terms of their ability to reflect, discover, and create new knowledge. Examples are provided of the way in which knowledge and the classification process…

Drawing upon an efficacious method for discovering previously unknown causes of medical syndromes and searching in the Humanities Index, an illuminating new humanities analogy between the epistemological ideas of Robert Frost and the ancient Greek philosopher Carneades was found by constructing a search statement in which proper names were coupled…

Discussion of the need to filter and retrieval relevant information from the Internet focuses on the use of mobile agents, specific software components which are based on distributed artificial intelligence and integrated systems. Surveys agent technology and discusses the agent building package used to develop two applications using IBM's Aglet…

This article explores second language (L2) learners' interpretation of reflexive anaphora in VP-Ellipsis by critiquing the work of Ying (2003), who applies Relevance Theory to explain elliptical anaphora. It argues against four claims made in his analysis: that L2 learners apply maximal relevance in anaphoric interpretation; that a procedural…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

This study explored the use of a problem-based learning (PBL) approach for teaching information and communication technology (ICT) skills to first-year students. Two questions were posed. The first addressed the ICT skill needs of 20 students enrolled in a first-year composition course. The second focused on the use of PBL to facilitate ICT skill…

An instructional development project at the University of Kansas focused upon two major objectives: (1) to develop teaching strategies to introduce engineering students and faculty to literature searching on computerized data bases, and (2) to help students develop effective on-line search strategies. A faculty workshop and an undergraduate…

Two programs addressed the development of information retrieval systems useful to a variety of users. One program was designed to examine aspects of indexing and information display. Experiments with different indexing and display systems revealed that for good relevance judgements, a display with full citation, keyboards, and abstract is…
