Abstract

Reports a study which examined and assessed the search techniques of trained end-users to determine whether or not they were searching the system affectively. 131 multilingual graduate students at Baruch College, City University of New York searched a full-text system and completed a survey that asked them to evaluate the system and describe their search strategy and techniques. 55% indicated dissatisfaction with their searches. Correlations between native language and searching results and satisfaction are shown. Findings suggest that computer-literate end users with prior experience searching other databases and formal training experience more difficulties than in commonly realized. Discusses the implications for training

Abstract

The study explored how people in two different cultures conduct two types of subject searches. Twenty-four American students and 40 Taiwanese students were given the same task looking for answers on the Internet by navigating through directories and by using keywords in the American-based Yahoo services. The findings pointed to differences between the groups due to their familiarity with the English language. On the other hand, presumed cultural differences did not seem to result in different search behaviors or preferences. These findings were preliminary and suggestions for future research were made.

Abstract

We report on a study that was undertaken to better understand search and navigation behavior by exploiting the close association between the process underlying users' query submission and the navigational trails emanating from query clickthroughs. To our knowledge, there has been little research towards bridging the gap between these two important processes pertaining to users' online information searching activity. Based an log data obtained from a search and navigation documentation system called AutoDoc, we propose a model of user search sessions and provide analysis an users' link or clickthrough selection behavior, reformulation activities, and search strategy patterns. We also conducted a simple user study to gauge users' perceptions of their information seeking activity when interacting with the system. The results obtained show that analyzing both the query submissions and navigation starting from query clickthrough, reveals much more interesting patterns than analyzing these two processes independently. On average, AutoDoc users submitted only one query per search session and entered approximately two query terms. Specifically, our results show how AutoDoc users are more inclined to submit new queries or resubmit modified queries than to navigate by linkfollowing. We also show that users' behavior within this search system can be approximated by Zipf's Law distribution.

Abstract

In this study descriptions of a novel by 100 users at 2 Swedish public libraries, Malmö and Molndal, Mar-Apr 95, were compared to the index terms used for the novels at these libraries. Describes previous systems for fiction indexing, the 2 libraries, and the users interviewed. Compares the AMP system with their own model. The latter operates with terms under the headings phenomena, frame and author's intention. The similarities between the users' and indexers' descriptions were sufficiently close to make it possible to retrieve fiction in accordance with users' wishes in Molndal, and would have been in Malmö, had more books been indexed with more terms. Sometimes the similarities were close enough for users to retrieve fiction on their own

Abstract

During the fall 2001 semester 15 first-year undergraduates were interviewed about their information-seeking behavior. Undergraduates completed a short-answer questionnaire, the Measure of Epistemological Reflection, measuring their epistemological beliefs and searched the Web and an online public access catalog using tasks from the Reflective Judgment Interview that assessed their reflective judgment level. Undergraduates talked aloud while searching digital environments about the decisions they were making about the information they encountered while transaction analyses software (Lotus ScreenCam) recorded both their search moves and their decision-making through verbal protocol analysis. Analyses included examining the relationship between undergraduates' epistemological beliefs and reflective judgment and how they searched for information in these digital environments. Results indicated that there was a relationship between epistemological beliefs and reflective judgment and information-seeking behavior. Undergraduates' at higher stages of epistemological development exhibited the ability to handle conflicting information sources and to recognize authoritative information sources.

Abstract

Presents a study questioning catalogue users at Emporia State Univ. about their experiences and their evaluation of NOTIS in order to access how patrons felt about the catalogue and how well they used it. The study focused on the instruction offered by 59 randomly selected NOTIS libraries. Responses were solicited concerning the university or college, the library, and training methods for OPAC users. With the information gained through both parts, the library instruction program and information regarding NOTIS at White Library could be evaluated and modified

Abstract

Examines sex differences in library anxiety, computer anxiety and using computers for library research anxiety in 40 academically oriented high school seniors for 1 year. Finds boys to have higher library anxiety than girls. Girls have a higher anxiety in the remaining 2 categories involving computers. Both sexes improved in all 3 areas except for girls on the computers for library research. Girls may experience less anxiety when using computers in a non mathematical setting but the detrimental effect of computers may compromise girls' attitudes to computer mediated library research

Abstract

Observes that whether in academic, special, or public libraries or on commercial online systems, CD-ROM, the online catalogue, or the Internet, certain end user errors crop up repeatedly. Details the main errors, which include input errors, errors arising from confusion in the face of different interfaces and screen designs, Boolean logic errors, term errors, conceptual errors, and errors due to the fact that users do not read instructions. Concludes that systems must solve the trivial errors automatically, but user instruction librarians must help solve the more complex problems

Abstract

People frequently answer consequential questions, such as those with a medical focus, using Internet search engines. Their primary goal is to revise or establish beliefs in one or more outcomes. Search engines are not designed to furnish answers, and instead provide results that may contain answers. Information retrieval research has targeted aspects of information access such as query formulation, relevance, and search success. However, there are important unanswered questions on how beliefs-and potential biases in those beliefs-affect search behaviors and how beliefs are shaped by searching. To understand belief dynamics, we focus on yes-no medical questions (e.g., "Is congestive heart failure a heart attack?"), with consensus answers from physicians. We show that (a) presearch beliefs are affected only slightly by searching and changes are likely to skew positive (yes); (b) presearch beliefs affect search behavior; (c) search engines can shift some beliefs by manipulating result rank and availability, but strongly-held beliefs are difficult to move using uncongenial information and can be counterproductive, and (d) search engines exhibit near-random answer accuracy. Our findings suggest that search engines should provide correct answers to searchers' questions and develop methods to persuade searchers to shift strongly held but factually incorrect beliefs.

Abstract

New users encounter numerous stumbling blocks in their search for periodicals, including use of indexes; understanding the citation; searching the online catalogue for the periodical record; interpreting the periodicals holdings; and finally locating the item on the shelf. Each step presents problems that users bring to the reference desk. Suggests user oriented solutions relating to cataloguing practices, screen design, and linking local holdings to periodical databases. Increased collaboration between librarians and those creating the records and providing the access is essential for meeting end user needs

Abstract

This paper discusses an approach of collecting qualitative data on human information behaviour that is based on mining web data using search engines. The approach is technically the same that has been used for some time in webometric research to make statistical inferences on web data, but the present paper shows how the same tools and data collecting methods can be used to gather data for qualitative data analysis on human information behaviour.

Abstract

The paper presents the results of a study on usability methods for evaluating Web sites. It summarizes the "Heuristics for Web Communications," and reports the practical experiences with these heuristics, contrasting them with the "Keevil Index" and combining them with user testing with thinking aloud. It concludes that working with the "Heuristics for Web Communications" takes more time and effort than working with the "Keevil Index," but produces more consistent results. The heuristics proved to be applicable both in heuristic evaluation and in combination with user testing.
