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 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

Investigates search intermediary elicitations during mediated online searching. A study of 40 online reference interviews involving 1.557 search intermediary elicitation, found 15 different types of search intermediary elicitation to users. The elicitation purpose included search terms and strategies, database selection, relevance of retrieved items, users' knowledge and previous information seeking. Analysis of the patterns in the types and sequencing of elicitation showed significant strings of multiple elicitation regarding search terms and strategies, and relevance judgements. Discusses the implications of the findings for training search intermediaries and the design of interfaces eliciting information from end users

Abstract

Presents selected results from a large study which observed under real-life conditions the interaction between users, intermediaries and computers before and during online searching. Concentrates on the sources of search terms and the relation between given search terms and retrieval of relevant and nonrelevant items as answers. Users provided the largest proportion of search terms (61%), followed by the thesuaurs (19%), relevance feedback (11%), and intermediary (9%). Only 4% of search terms resulted in retrieval of relevant items only; 60% retrieved relevant and nonrelevant items; 25% retrieved nonrelevant items only; and 11% retrieved nothing.

Abstract

One in a series of studies on the selection of search terms during an online search involving users and intermediaries in real online interactive situations. Considers: during what stage of the search process were search terms from different sources selected?; how were the search terms selected at different stages of the search process connected with retrieval of relevant answers as judges by users?; and in what sequences were the search terms selected, in respect to their sources. Sequences of selected search terms were analyzed to describe the types and frequencies of changes that occur in such sequences. Results indicate that search term selection follows regular patterns in the dynamics of the search process. Discusses implications of findings

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 Web and especially major Web search engines are essential tools in the quest to locate online information for many people. This paper reports results from research that examines characteristics and changes in Web searching from nine studies of five Web search engines based in the US and Europe. We compare interactions occurring between users and Web search engines from the perspectives of session length, query length, query complexity, and content viewed among the Web search engines. The results of our research shows (1) users are viewing fewer result pages, (2) searchers on US-based Web search engines use more query operators than searchers on European-based search engines, (3) there are statistically significant differences in the use of Boolean operators and result pages viewed, and (4) one cannot necessary apply results from studies of one particular Web search engine to another Web search engine. The wide spread use of Web search engines, employment of simple queries, and decreased viewing of result pages may have resulted from algorithmic enhancements by Web search engine companies. We discuss the implications of the findings for the development of Web search engines and design of online content.

Abstract

Major Web search engines, such as AItaVista, are essential tools in the quest to locate online information. This article reports research that used transaction log analysis to examine the characteristics and changes in AItaVista Web searching that occurred from 1998 to 2002. The research questions we examined are (1) What are the changes in AItaVista Web searching from 1998 to 2002? (2) What are the current characteristics of AItaVista searching, including the duration and frequency of search sessions? (3) What changes in the information needs of AItaVista users occurred between 1998 and 2002? The results of our research show (1) a move toward more interactivity with increases in session and query length, (2) with 70% of session durations at 5 minutes or less, the frequency of interaction is increasing, but it is happening very quickly, and (3) a broadening range of Web searchers' information needs, with the most frequent terms accounting for less than 1% of total term usage. We discuss the implications of these findings for the development of Web search engines.
