Explains an experiment in text-searching retrieval for cancer questions which developed and used computer procedures (via human simulation) to select search words from medical dictionaries. This study is based on an earlier one in which search words were humanly selected, and the recall results of the two studies are compared. (Author/LRW)

The techniques of search strategy design for substructure searches of the Wiswesser Line Notation (WLN) file are described in detail. The Index Chemicus Registry System'' was used. (13 references) (Author/SM)

The objectives of this paper are to describe the effect of using weighted index terms in a document retrieval system, and to evaluate retrieval performance when queries are expanded by terms occurring in clusters with the query terms. Three data collections, each indexed by several methods, two of which were studied and reported on in previous…

WISE-ONE is a bibliographic information retrieval system which is designed to perform keyword searches of such data-bases as the ERIC RESUMAST and the ERIC CIJEMAST. Produced as a result of the search are the ERIC citation numbers, titles, authors, and, in the case of the journal file, the journal citation. Because WISE-ONE allows for nesting of…

In Part I of the Session, Network members describe and compare their experiences in utilizing various aspects of the SUNY Retrieval System including "query" cycle, scan statements, author searches, and book files. Machine problems are discussed as well as options on charging for searches, how much information to retrieve, and serving…

The relative retrieval performances of the CA Integrated Subject File (CAISF), CA Condensates, and a Merged File created from these two data bases were measured. Retrieval performance is reported in terms of recall, precision values, and costs. (Author/JB)

Minimum, maximum, and average lengths and frequency counts for the data elements in the Chemical Substance and General Subject segments of the Standard Distribution Format (SDF) files distributed by Chemical Abstracts Service are presented. (5 references) (Authors)

An evaluation of graph theoretical clusters of index terms which can be extracted from an automatically indexed document collection, and the effects of employing such clusters in automatic document retrieval are described. (19 references) (Author)

The Educational Resources Information Center (ERIC) system's computerized data base was the focus of a three-hour tutorial session on search strategies. This document is the workshop manual used by the tutorial participants. The discussion of the input phase of a computer search covers identification of the user population, receiving the inquiry,…

The purpose of this small scale study was to make a preliminary assessment of the potential value of the ERIC data base for educators in Britain. On-line searches of the ERIC data base were conducted for a sample of fourteen users who were asked to comment on the relevance of retrieved materials. Results indicate that ERIC can provide access to…

Reports on the design and use of a computer system--SORT-AID--to assist bibliographic database searchers in the post-search, analysis phase of their work. Designed for National Aeronautics and Space Administration (NASA) installations, this system automatically determines the relevance of downloaded abstracts and provides facilities for editing…

With the number and types of documents in digital library systems increasing, tools for automatically organizing and presenting the content have to be found. While many approaches focus on topic-based organization and structuring, hardly any system incorporates automatic structural analysis and representation. Yet, genre information…

The purpose of this guide is to give an up-to-date presentation of the information service offered by the documentation center at the Royal Institute of Technology (RIT) and to facilitate the utilization of the service. The guide gives a general account of the multidisciplinary computerized current awareness service (SDI) and a detailed…

The transfer of information through space and time in communication systems is often accompanied by significant delays which give rise to meaningful storage problems. Mathematical models have been developed for the study of these kinds of problems which are applicable to the design of manual, library-type, or mechanized information storage and…

Presents abstracts that discuss using data visualization for information retrieval and data mining, including immersive information space and spatial metaphors; spatial data using multi-dimensional matrices with maps; TREC (Text Retrieval Conference) experiments; users' information needs in cartographic information retrieval; and users' relevance…
