Six uses of classification in online retrieval systems are envisioned--to improve recall and precision; to conceptualize meaning of vague search terms; to provide structure for browsing; to provide framework for retrieval of nonbibliographic information; to collocate citations; and to achieve compatibility of retrieval languages. Seven sources are…

Describes the use of three alternative methods for ranking films for information retrieval (IR). A large film-person incidence matrix is generated using the principle cast, directors, producers and screenwriters for each film. These attributes are used to measure film-film distances by creating a distance matrix. Distance, product distance, and…

Findings from a study of users' multitasking searches on Web search engines include: multitasking searches are a noticeable user behavior; multitasking search sessions are longer than regular search sessions in terms of queries per session and duration; both Excite and AlltheWeb.com users search for about three topics per multitasking session and…

This report includes data on the cognitive and affective behavior of college students who were given the tasks of interpreting and formulating Boolean search statements. Two versions of written point-of-use instructions on Boolean searching, affectively elaborated and unelaborated, were given to investigate comprehension, self-confidence, and…

Describes an inductive, qualitative study of 30 Syracuse University students that investigated the situated nature of action during interactions with an online public access catalog. Highlights include elements of situatedness, with examples; the mapping of individual searches; and users' goals and stopping behavior. (Author/LRW)

Presents a general model of the information-seeking process. Various aspects of information-seeking behavior are projected over an organizational and behavioral framework; three dimensions of information-seeking behavior are described, i.e., the conditions, the context, and the process; interactions among these dimensions are considered; and…

Examines historical and current difficulties in information retrieval, including the tendency of technology, because of the problems of scale and distribution, to make information invisible to users. Attempts to organize networked resources are described, and serendipity is proposed as a model for future retrieval. (two references) (MES)

Reports the results of part one of a multi-faceted research project investigating children's information-seeking behavior in using World Wide Web search engines, with reference to Yahooligans. Examines search processes, patterns of exploration of returned results, success in finding/retrieving relevant information, persistence in finding…

When systems of ordering, such as classifications and thesauri, are used, two mappings are involved: objects (documents) in the collection and searchers' queries. Four means to achieve this are: relative indexes; syndetic structures; entry vocabulary indexes; and human intermediaries. These forms can supplement and augment each other. The…

This study examined the influence of three different combinations of document structures and menu designs on users' attitude, performance, and learning in five different search tasks. The three types of combinations studied were: (1) an explicit menu signaling hierarchical structure where cross-referencing was not supported (EXH--explicit and…

As libraries automate their collections and mount online public access catalogs (OPACs), they face special challenges in educating patrons to use these electronic systems effectively and efficiently. Because users are less familiar with the concept and arrangement of an OPAC than with a card catalog, less successful searches commonly occur.…

An inter-university network of computer centers, the "Because It's Time NETwork" (BITNET), is described. Specific guidelines and format requirements for using BITNET, with sample commands, are presented. More than 1,800 computers at over 600 institutions of higher education and research centers in Europe, Asia, and North America are…

Designed to provide students of information science with an introduction to British librarian Samuel Clement Bradford's 1934 findings about the scattering of information, this reader on Bradford's Law begins by discussing its use in calculating search procedures in printed bibliographies as well as in databases. The following additional materials…

The proliferation of the mastery learning literature over the past decade has acutely intensified the need for the formation of a specific Clearinghouse on Mastery Learning (CML). An attempt at establishing such a clearinghouse has been under way for the past year through the Loyola Center for Educational Improvement, based at Loyola University in…

Extensionists need to make the "ASIAn Connection"--become Aware of the spectrum of research, Select program-related research, Integrate research from many disciplines, and Apply it in a way useful to clientele. Extensionists currently use a wide variety of traditional techniques to make the "ASIAn Connection." One relatively new technique has…
