In this research project, the authors set out to discover the current practice in both the archival and cataloging worlds for usage of access points in descriptive records and to learn how archival descriptive practices fit into long-established library cataloging procedures and practices. A sample of archival finding aids and MARC records at 123…

The visual system uses several tools to select only the most relevant visual information for further processing, including selection by location. In the present study, the authors explored how many locations can be selected at once. Although past evidence from several visual tasks suggests that the visual system can operate on a fixed number of 4…

Retrieving a subset of previously studied material can impair later recognition of related items. Using the remember-know procedure (Experiment 1) and the receiver operating characteristic procedure (Experiment 2), the authors examined how such retrieval-induced forgetting can be explained in terms of single-process and dual-process accounts of…

With the dramatic growth of text information, there is an increasing need for powerful text mining systems that can automatically discover useful knowledge from text. Text is generally associated with all kinds of contextual information. Those contexts can be explicit, such as the time and the location where a blog article is written, and the…

This article provides a critical analysis of some of the key theories and assumptions that underpin prevailing approaches to the concept of "information user" in contemporary information research and professional practice, suggesting that they continue to reflect a tacitly systems-oriented focus. The author draws on the Sense-Making…

Purpose: The purpose of this paper is to make a scientific contribution to web information retrieval (IR). Design/methodology/approach: A multiagent system for web IR is proposed based on new technologies: Hierarchical Small-Worlds (HSW) and Possibilistic Networks (PN). This system is based on a possibilistic qualitative approach which extends the…

Introduction: Investigates how effectively Web search engines index new sites from different countries. The primary interest is whether new sites are indexed equally or whether search engines are biased towards certain countries. If major search engines show biased coverage it can be considered a significant economic and political problem because…

In experimental searches of "Basic Journal Abstracts" using the subject terms from 104 selective dissemination of information profiles, retrieval was found to be significantly worse if only titles were searched rather than the full title and abstract. (PF)

Poses questions concerning methods of using specificity information in a weighting scheme. (JB)

The model assumes that the relevance assigned to a document by a juror is a random variable. (PF)

A threshold rule is analyzed and compared to the Neyman-Pearson procedure, indicating that the threshold rule provides a necessary but not sufficient measure of the minimal performance of a retrieval system, whereas Neyman-Pearson yields a better apriori decision for retrieval. (Author/MBR)

The use of a structured system of storing information, particularly relational indexing, can lead to situations in which items would not be retrieved due to technicalities of the system. To overcome such problems a study was made of condensations with the aim of providing a series of rules to apply. (4 references) (Author/SJ)

There are six major studies of the effect of indexing depth on retrieval performance. They differ in purpose, methodology, measures, indexing language, field of study, and data base--nevertheless, all have found depth of indexing to have the same effect upon information retrieval.

The work described was designed to test the feasibility of using automatic or semi-automatic methods to replace or reduce the intellectual effort involved in retrieving information from machine readable stores, particularly those using natural language. (Author)
