- 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.

- Abstract
- Data from Westminster Libraries on membership, borrowing frequency and stock use is compared with significant studies of public library use from the last 50 years. The article examines the extent of public library use, and the social and demographic factors influencing use. Analysis of book and audio-visual stock use indicates the concentration of demand on a few titles and subjects, and the relationship to what is in demand commercially. Aspects of public library use have remained constant over at least the last 50 years, and across geographical boundaries. Public libraries are used principally for leisure, for borrowing recent fiction, for useful non fiction related to immediate life interests, and for pop music. Quantitative data from library systems provides a different, probably more accurate, picture of the nature and extent of public library use.

- Abstract
- Suchmaschinen stellen eine wichtige Möglichkeit dar, um neue Informationen oder Webseiten im Internet zu finden. Das Online-Marketing wurde dadurch verstärkt auf das Suchmaschinen-Marketing ausgerichtet, bei dem vor allem darauf geachtet wird, dass man in Suchmaschinen gut sichtbar ist. Bei der effizienten Planung von Marketing-Aktionen ist es deshalb wichtig, nicht nur profunde Kenntnisse über die Funktionsweise von Suchmaschinen zu haben, sondern auch das Suchverhalten von Suchmaschinennutzern zu untersuchen und die Ergebnisse geeignet umzusetzen. In diesem Beitrag wird auf die Erforschung des Suchverhaltens im Web und auf die Interaktion von Menschen mit Suchmaschinen ab 1997 eingegangen. In erster Linie werden verschiedene Erhebungsmethoden erklärt und Analysen vorgestellt. Es wird auch diskutiert, wie die Ergebnisse umgesetzt werden können, um die Auffindbarkeit von Webseiten zu verbessern.

- Abstract
- The use of thesaurus-enhanced search tools is an the increase. This paper provides an insight into end-users interaction with and perceptions of such tools. In particular the overlap between users' initial query formulation and thesaurus structures is investigated. This investigation involved the performance of genuine search tasks an the CAB Abstracts database by academic users in the domain of veterinary medicine. The perception of these users regarding the nature and usefulness of the terms suggested from the thesaurus during the search interaction is reported. The results indicated that around 80% of terms entered were matched either exactly or partially to thesaurus terms. Users found over 90% of the terms suggested to be close to their search topics and where terms were selected they indicated that around 50% were to support a 'narrowing down' activity. These findings have implications for the design of thesaurus-enhanced interfaces.

- Content
- The objective of this research was to investigate the extent to which thesauri have the potential to support the search behaviour of nanoscience and technology researchers while interacting with an electronic book digital library. Transaction log data was obtained from a nanoscience and technology digital library to investigate the nature, type and characteristics of users' queries and search terms. The specific objectives was to assess the extent to which users' search terms matched with those found in two well-established thesauri attached o the INSPEC and Compendex databases.

- Abstract
- ADEPT is a 5-year project whose goals are to develop, deploy, and evaluate inquiry learning capabilities for the Alexandria Digital Library, an extant digital library of primary sources in geography. We interviewed nine geography faculty members who teach undergraduate courses about their information seeking for research and teaching and their use of information resources in teaching. These data were supplemented by interviews with four faculty members from another ADEPT study about the nature of knowledge in geography. Among our key findings are that geography faculty are more likely to encounter useful teaching resources while seeking research resources than vice versa, although the influence goes in both directions. Their greatest information needs are for research data, maps, and images. They desire better searching by concept or theme, in addition to searching by location and place name. They make extensive use of their own research resources in their teaching. Among the implications for functionality and architecture of geographic digital libraries for educational use are that personal digital libraries are essential, because individual faculty members have personalized approaches to selecting, collecting, and organizing teaching resources. Digital library services for research and teaching should include the ability to import content from common office software and to store content in standard formats that can be exported to other applications. Digital library services can facilitate sharing among faculty but cannot overcome barriers such as intellectual property rights, access to proprietary research data, or the desire of individuals to maintain control over their own resources. Faculty use of primary and secondary resources needs to be better understood if we are to design successful digital libraries for research and teaching.

- Abstract
- Describes a project which monitored electronically 11 public access terminals, at the Colorado University Librarys, to produce transaction logs that were used to gather statistics and analyze the behaviour of users when searching the library online catalogues. The study recorded user behaviour unobtrusively and focused exclusively on what actually occured during the search process. Among other findings it was revealed that the use of system supplied search aids varied, from low use of quick search and express search features, to more extensive use of search history and searching databases other than the home catalogue. Analysis of search results revealed that 66% of subject (keyword) and name searches produce 10 or fewer results, and 82% produce 25 or fewer titles, a manageable number for searchers to scan postings and spot relevant materials. User persistence in scanning titles was found to be high with the full list being requested for nearly 40% of searches netting up to 100 results. Overall, results show that emphasis on improved system design must be stressed if the needs of the majority of searchers are to be met more effectively

- Abstract
- A set of methods and results is offered for characterizing how people make decisions in the course of using computerized databases. In general, their performance resembles that revealed in studies of decision making in other contexts. In particular, people are only moderately sensitive to the likelihood of their succeeding, being overconfident for all but the easiest of tasks. These results are discussed in the context of previous research in information science and decision science, and with regard to their implications for the design of databases and the adaptation of users to them

- Abstract
- Thesauri have been important information and knowledge organisation tools for more than three decades. The recent emergence and phenomenal growth of the World Wide Web has created new opportunities to introduce thesauri as information search and retrieval aids to end user communities. While the number of web-based and hypertextual thesauri continues to grow, few investigations have yet been carried out to evaluate how end-users, for whom all these efforts are ostensibly made, interact with and make use of thesauri for query building and expansion. The present paper reports a pilot study carried out to determine the extent to which a thesaurus-enhanced search interface to a web-based database aided end-users in their selection of search terms. The study also investigated the ways in which users interacted with the thesaurus structure, terms, and interface. Thesaurusbased searching and browsing behaviours adopted by users while interacting with the thesaurus-enhanced search interface were also examined. 1. Introduction The last decade has witnessed the emergence of a broad range of applications for knowledge structures in general and thesauri in particular. A number of researchers have predicted that thesauri will increasingly be used in retrieval rather than for indexing (Milstead, 1998; Aitchison et al., 1997) and that their application in information retrieval systems will become more diverse due to the growth of fulltext databases accessed over the Internet (Williamson, 2000). Some researchers have emphasised the need for tailoring the structure and content of thesauri as tools for end-user searching (Bates, 1986; Strong and Drott, 1986; Anderson and Rowley, 1991; Lopez-Huertas, 1997) while others have suggested thesaurus-enhanced user interfaces to support query formulation and expansion (Pollitt et.al., 1994; Jones et.al., 1995; Beaulieu, 1997). The recent phenomenal growth of the World Wide Web has created new opportunities to introduce thesauri as information search and retrieval aids to end user communities. While the number of web-based and hypertextual thesauri continues to grow, few investigations have been carried out to evaluate the ways in which end-users interact with and make use of online thesauri for query building and expansion. The work reported here expands an a pilot study (Shiri and Revie, 2001) carried out to investigate user - thesaurus interaction in the domains of biology and veterinary medicine.

- Abstract
- Discusses the problems encountered by elementary school children in retrieving information from catalogues, either traditional card catalogues or OPACs. Describes an alternative system of classification using colours and symbols that was developed in The Common School of Amherst, Mass. The case study found that children do have the ability to use a classification scheme that is keyed to their developmental level and that employs both colours and symbols to facilitate their search efforts

- Abstract
- This article surveys the use of eye tracking in investigations of online search. Three eye tracking experiments that we undertook are discussed and compared to additional work in this area, revealing recurring behaviors and trends. The first two studies are described in greater detail in Granka, Joachims, & Gay (2004), Lorigo et al. (2006), and Pan et al. (2007), and the third study is described for the first time in this article. These studies reveal how users view the ranked results on a search engine results page (SERP), the relationship between the search result abstracts viewed and those clicked on, and whether gender, search task, or search engine influence these behaviors. In addition, we discuss a key challenge that arose in all three studies that applies to the use of eye tracking in studying online behaviors which is due to the limited support for analyzing scanpaths, or sequences of eye fixations. To meet this challenge, we present a preliminary approach that involves a graphical visualization to compare a path with a group of paths. We conclude by summarizing our findings and discussing future work in further understanding online search behavior with the help of eye tracking.

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- Abstract
- The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

- Abstract
- Presents a recently composite view of several user studies in information retrieval. Contains personal conclusions and speculations based on these studies, rather than formal statistical results, which so often are not comparable from 1 experiment to another. Suggests a taxonomy of user characteristics for such studies, in order to make results comparable. Discusses methods and effects of user training, then manner of expression of a query or information need, conduct of a search, use of the system command language or its equivalent, analysis by the user of retrieved information, and user satisfaction with outcome. Concludes with suggestions for system design and experimental methodology

- Abstract
- Patron queries at a four-year comprehensive college's online public access catalog were examined via transaction logs from March 2007. Three representative days were isolated for a more detailed examination of search characteristics. The results show that library users employed an average of one to three terms in a search, did not use Boolean operators, and made use of limits one-tenth of the time. Failed queries remained problematic, as a full one-third of searches resulted in zero hits. Implications and recommendations for improvements in the online public access catalog are discussed.

- Abstract
- I started my professional career in library and information science because of my great interest in knowledge organization. The more experience I gained in the profession, the more I realized how crucial it is to understand which organization would be best for each group of users. This in turn requires an understanding of how users seek information. And so now my focus is an studying information seeking and searching behavior. Throughout the relatively long course of changing my focus, I followed Pauline Cochrane's writings. Now I can say that she has been among the first to have a "user-centered approach" to knowledge organization, and she has used the term three years before it became a mainstream phrase. The following is a short discussion about the usercentered approach which was presented in a workshop in 1997.
