Proposes an information retrieval system based on a hybrid model consisting of an inductive learning and neural network system. Evaluates the system's responses to incomplete queries and inconsistent indexing. Query terms, discriminant descriptors, and the American Documentation Institute's query and document titles used in the evaluation are…

Text similarity measurements are used to determine relationships between natural-language texts and text excerpts. The resulting linked hypertext maps can be broken down into text segments and themes used to identify different text types and structures, leading to improved information access and utilization. Examples are provided for text…

Examines how information processing theory provided a way to retrieve and structure an individual's 25 years of practical public school administration experience. Describes the resulting framework of "knowledge boxes" including: declarative knowledge, procedural knowledge, conditional knowledge, and enabling knowledge. Organization of…

Surveys theoretical and practical issues associated with pictorial information retrieval. Concentrating on still and moving pictorial forms of the visual image, this paper focuses on indexing pictorial material and discusses four models of pictorial information retrieval corresponding with permutations of the verbal and visual modes for the…

Discusses hardware requirements, functions, and applications of five information processing and desktop publishing software packages for the Macintosh: HyperCard, PageMaker, Cricket Presents, Power Point, and Adobe illustrator. Benefits of these programs for schools are considered. (MES)

Develops a contingency model for managing a variety of corporate crises. Views crisis management as an information-processing situation and organizations that must cope with crisis as information-processing systems. Attempts to fit appropriate information-processing mechanisms to different categories of crises. (PRA)

Explains the value of neurocomputing as a unique and effective new technological concept for information processing and optical character recognition. Comparisons are made to digital computing and examples of applications such as recognizing handprinted characters are addressed. Products available from various companies are described. (Contains…

Proposes a composite feature measure which combines the shape and color features of an image based on a clustering technique. A similarity measure computes the degree of match between a given pair of images; this technique can be used for content-based image retrieval of images using shape and/or color. Tests the technique on two image databases;…

Originally written in the 1950s, this article addresses the question of subdividing and grouping entries under a given author as a main entry that paved the way for the American Library Association's Catalog Code Revision of 1967. It also includes referee responses by Elaine Svenonius, Allyson Carlyle, and Michael Carpenter. (LRW)

Describes Pharos, a prototype that automatically classifies and summarizes Internet newsgroups using the Library of Congress Classification (LCC) scheme. Topics addressed include the methodology of collection summarization and selection, constructing an online LCC outline, evaluation, limitations of the system, and classification of nontextual…

Longitudinal study examined 6-year-olds' performance in tasks involving a protagonist with partial information about an object or a person. Found that children who demonstrated some understanding of the consequences of limited information access often made other errors. Despite intervening additions of contextual support and clarifications, the…

Discusses responses to Needham's research on infants' use of featural, physical and experiential information to segregate displays. Considers characterization of different kinds of information infants use when segregating objects. Discusses relations between processes underlying object segregation. Considers the roles of visual versus linguistic…

Two experiments tested the hypothesis that subjects introduced to a first programming language develop a representation of basic programming concepts that help them integrate new declarative knowledge from a second programming language. The effect on reading was greater for pages that were conceptually close across texts and for subjects who had…

Discusses the potential for visualization of metadata and metadata-based surrogates, including a command interface for metadata viewing, site mapping and data aggregation tools, dynamic derivation of surrogates, and a reintroduction of transient hypergraphs from the tradition of cocitation networking. Addresses digital library research into…

Protein Annotators' Assistant (PAA) is a software system which assists protein annotators in assigning functions to newly sequenced proteins. PAA employs a number of information retrieval techniques in a novel setting and is thus related to text categorization, where multiple categories may be suggested, except that in this case none of the…
