Abstract

Reports selected results from a larger study whose objectives are to observe, under real life conditions, the nature and patterns of interaction between users, intermediaries, and computer sysrtems in the context of online information searching and retrieval. Reports various analyses on the relation of search term sources and the retrieval of items judges as to their relevance. While the users generated the largest proportion of search terms (61%) which were responsible for 68% of retrieved items judges relevant, other sources in the interaction process played an important role

Abstract

The relationship between user characteristics and the outcome of an online search is a growing area of investigation. Reports results of a study which examined use characteristics during mediated online searching in an academic environment, which related to online search outcome. Results of the study indicate that the academic status of the users and their experience of a prior online search on their information problem was significantly related to the online search outcome

Abstract

Reports selected results from a large study, conducted at Rutgers University, NJ, which observed, under real life conditions the interactions between users, intermediaries and information retrieval systems before and during online searching. Examines the stages of the search process at which search terms from different sources were selected and how the search terms selected at different stages of the search process contributed to the retrieval of relevant items as judged by users. Notes the sequences in which terms were selected and analyzes the sequences to determine the types and frequencies of changes that occur in such sequences. Results indicate that there are regular patterns in search term selection during the online search process. Discusses the implications of these findings

Abstract

Reports findings from an explanatory study investigating working notes created during encoding and external storage (EES) processes, by human search intermediaries using a Boolean information retrieval systems. Analysis of 221 sets of working notes created by human search intermediaries revealed extensive use of EES processes and the creation of working notes of textual, numerical and graphical entities. Nearly 70% of recorded working noted were textual/numerical entities, nearly 30 were graphical entities and 0,73% were indiscernible. Segmentation devices were also used in 48% of the working notes. The creation of working notes during the EES processes was a fundamental element within the mediated, interactive information retrieval process. Discusses implications for the design of interfaces to support users' EES processes and further research

Abstract

Reports results of research to examine users conducting their initial online search on a particular information problem. Findings from 3 separate studies of relevance judgements by 44 initial search users were examined, including 2 studies of 13 end users and a study of 18 user engaged in mediated online searches. Number of items was judged on the scale 'relevant', 'patially relevant' and 'not rlevant'. Results suggest that: a relationship exists between partially rlevant items retrieved anch changes in the users' information problem or question during an information seeking process; partial relevance judgements play an important role for users in the early stages of seeking information on a particular information problem; and 'highly' relevant items may or may not be the only items useful at the early stages of users' information seeking processes

Abstract

Considers what elicitation or requests for information search intermediaries make of users with information requests during an information retrieval interaction - including prior to and during an information retrieval interaction - and for what purpose. Reports a study of elicitations during 40 mediated information retrieval interactions. Identifies a total of 1.557 search intermediary elicitations within 15 purpose categories. The elicitation purposes of search intermediaries included requests for information on search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and users' knowledge and previous information seeking. Investigates the transition sequences from 1 type of search intermediary elicitation to another. Compares these findings with results from a study of end user questions

Abstract

Reports from a study investigating the extent to which academic end users conduct multiple search sessions, over time woth OPAC or CD-ROM databases at different stages of their information seeking related to a current research project. Interviews were conducted using a questionnaire with 200 academic end users at Rutgers University Alexander Library, NJ and University of North Texas, to investigate the occurrence of multiple search sessions. Results show that at the time of the survey interview, 57% of end users had conducted multiple search sessions during their research project and 86% of end users conducted their 1st search session at the beginning stage of their information seeking process. 49% of end users had conducted between 1 and 6 search sessions and 8% more than 6 search sessions. 70% of multiple search sessionss end users had modified their search terms since their 1st search session. Discusses the implications of the findings for end user training, information retrieval systems design and further research

Abstract

This paper reports findings from Phase I of the Wynnewood Study - a major project investigating the information-seeking and information needs of lowincome African-American households in the Wynnewood Project in Dallas, Texas. The Parks at Wynnewood is a residential housing development at which the University of North Texas (UNT) is currently conducting the Healthy Neighbourhoods urban revitalization project. This study is also part of the second phase of a major UNT project that is investigating the community service needs of the Wynnewood residents. During this needs assessment all Wynnewood households were interviewed using an extensive twelve-page questionnaire, including a number of questions on their information needs and information-seeking behaviour. The results of the survey provide data bearing on the development of an information resource center and an information literacy programme for Wynnewood community residents. A model of resident's information environment is presented. The study of information-seeking and information needs, also known as nonwork information-seeking or citizen information-seeking, is an important and emerging area of interdisciplinary information science research. More specifically, this study is providing important data on the everyday life information needs and seeking behaviours of low-income African Americans households.
