    Abstract
    Internet use research has focused on user surveys and novice learner studies, using survey, experimental, and ethnographic methods. They share a focus on user-based categories in the affective and cognitve domains. Information behaviour has an affective component that influences the direction of cognitive processing through hierarchically organized goals, characterized by both an individual and a cultural component. Research in human-computer interaction is evolving a user-centred methodology for system design and instruction that focuses on integrating affective and cognitive user variables to increase productivity, creativity, and human growth

    Abstract
    Two studies are presented that investigate information seeking behaviour on the Internet. In study one, soccer fans' information seeking on the World Wide Web is investigated. In study two, access rates to a cancer information Web site are analysed. It is tentatively argued that there is a tendency for people to access information more commonly avoided in "real life", although in the case of football fans, the tendency to "bask in reflected glory" remains when online, while cutting off reflected failure is minimised. Implications for understanding and researching psychological processes of Web browsing behaviour are discussed.

    Abstract
    Examines the problem of a compelling online news delivery system by focusing on how mass media audiences and online users differ in their assessment of news. It employed a 2-wave USA national survey to study the perception of interactivity in mass media and computer networks and its relationship to the assessment of news. The 1st wave looked a national probability sample, ahile the 2nd targeted viewers of NBC Nightly News who responded to the show via e-mail. NBC respondents rated mass media to be less interactive, while they rated computer communication more interactive than the national sample. The NBC group also rated mass media news less important and of lower quality than did the national sample. Interactivity ratings did not predict mass media credibility assessment for either group. However, respondents who defined interactivity as cybernetic feedback or who contacted NBC by e-mail rated computer communication to be more credible than thos who did not

    Abstract
    As more people gain at-home access to the Internet, information seeking an the Web has become embedded in everyday life. The objective of this study was to characterize the home as an information use environment and to identify a range of information seeking and Websearch behaviors at home. Twelve Northern California residents were recruited, and the data were collected through semi-structured at-home interviews based an a self-reported Search Activities Diary that subjects kept over a 3-5 day period. The data were analyzed an four levels: home environment, information seeking goals, information retrieval interaction, and search query. Eindings indicated that the home, indeed, provided a distinct information use environment beyond physical setting alone in which the subjects used the Web for diverse purposes and interests. Based an the findings, the relationships among home environment, Web context, and interaction situation were identified with respect to user goals and information-seeking behaviors.

    Abstract
    According to many studies, social network sites (SNS) have become some of the most popular online destinations. It has been pointed out that very little is known about the psychosocial variables that predict people's use of these websites. In this article, our general objective is to understand behavioral intentions to use SNS employing the well-known unified theory of acceptance and use of technology (UTAUT), which has been validated in a number of studies. Data were collected through a questionnaire survey from a final sample of 1,039 social networking website users in Africa. We have shown that there are contexts, such as the African context, in which the UTAUT does not hold up. Explanations are provided to support the findings.

    Abstract
    Subject content analysis of Web query terms is essential to understand Web searching interests. Such analysis includes exploring search topics and observing changes in their frequency distributions with time. To provide a basis for in-depth analysis of users' search interests on a larger scale, this article presents a query categorization approach to automatically classifying Web query terms into broad subject categories. Because a query is short in length and simple in structure, its intended subject(s) of search is difficult to judge. Our approach, therefore, combines the search processes of real-world search engines to obtain highly ranked Web documents based on each unknown query term. These documents are used to extract cooccurring terms and to create a feature set. An effective ranking function has also been developed to find the most appropriate categories. Three search engine logs in Taiwan were collected and tested. They contained over 5 million queries from different periods of time. The achieved performance is quite encouraging compared with that of human categorization. The experimental results demonstrate that the approach is efficient in dealing with large numbers of queries and adaptable to the dynamic Web environment. Through good integration of human and machine efforts, the frequency distributions of subject categories in response to changes in users' search interests can be systematically observed in real time. The approach has also shown potential for use in various information retrieval applications, and provides a basis for further Web searching studies.

    Abstract
    Usability of Web sites has become an increasingly important area of research as Web sites proliferate and problems with use are noted. Generally, aspects of Web sites that have been investigated focus on such areas as overall design and navigation. The exploratory study reported on here investigates one specific component of a Web site-the index structure. By employing index usability metrics developed by Liddy and Jörgensen (1993; Jörgensen & Liddy, 1996) and modified to accommodate a hypertext environment, the study compared the effectiveness and efficiency of 20 subjects who used one existing index (the A-Z index on the FedStats Web site at http://www.fedstats.gov) and three experimental variants to complete five researcher-generated tasks. User satisfaction with the indexes was also evaluated. The findings indicate that a hypertext index with multiple access points for each concept, all linked to the same resource, led to greater effectiveness and efficiency of retrieval on almost all measures. Satisfaction measures were more variable. The study offers insight into potential improvements in the design of Web-based indexes and provides preliminary assessment of the validity of the measures employed

    Abstract
    Purpose - A common criticism of research into information seeking on the internet is that information seekers are restricted by the demands of the researcher. Another criticism is that the search topics, are often imposed by the researcher, and; particularly when working with children, domain knowledge could be as important as information-seeking skills. The research reported here attempts to address both these problems. Design/methodology/approach - A total of 15 children, aged 11 to 16, were each set three "think aloud" internet searches. In the first, they were asked to recall the last time they had sought information on the internet, and to repeat the search. For the second, they were given a word, asked to interpret it, then asked to search for their interpretation. For the third, they were asked to recall the last time they had been unsuccessful in a search, and to repeat the search. While performing each task, the children were encouraged to explain their actions. Findings - The paper finds that the factors that determined a child's ability to search successfully appeared to be: the amount of experience the child had of using the internet; the amount of guidance, both from adults and from peers; and the child's ability to explore the virtual environment, and to use the tools available for so doing. Originality/value - Many of the searches performed by participants in this paper were not related to schoolwork, and so some of the search approaches differed from those taught by teachers. Instead, they evolved through exploration and exchange of ideas. Further studies of this sort could provide insights of value to designers of web environments.

    Abstract
    Faculty members from a major university were surveyed to explore the possible relationship between Internet usage and the following dependent variables: computer usage (length of time and perceived expertise), length of time of Internet use, perceived expertise of Internet use, and perceived utility of the Internet. 97% have an Internet account. Furthermore, computer literacy and length of computer experience are correlated with early adoption of the Internet, perceived utility of the Internet is correlated with computer literacy and with Internet usage, and usage is correlated with perceived expertise, but not with the length of time of Internet experience. Highly skilled computer users are more likely to use the network in a more intensive way and have higher appreciation of the network's potential

    Abstract
    Focuses on how satisfied Australian academics are when they use the Internet to search for information. Results validated magnitude estimates of user satisfaction with information seeking on the Internet. Testing the validity and reliability magnitude estimation as a technique for gathering and analysing interval data on satisfaction with information seeking was key to the investigation. Data for user satisfaction were then associated with end user characteristics like training, frequency of use and expectation of success. They have a high expectation of success when they engage in information seeking on the Internet and are satisfied with the process regardless of how frequently they use the network or whether or not they have formal training

    Abstract
    There's something magical about interface design. The research done to determine user behavior that leads to design decisions is positively fascinating. This time round we have a group at Penn State testing the proficiency of users on their brand new OPAC. The users were divided into two groups, "experienced" and "first-time". Results confirm other studies in this area, namely, that when confronting an OPAC, users both experienced and not, assume they're in front of something similar to Google. They go for keywords by default, expect results ranked by relevancy (as opposed to chronology), make no use of Boolean Operators, have no idea of what information is actually indexed, and lack the curiosity or time to "learn the system". "We can either abandon this population," the author stresses, "or design systems that do not require expert knowledge to be used effectively.

    Abstract
    In this article, we investigate the criteria used by online searchers when assessing the relevance of Web pages for information-seeking tasks. Twenty-four participants were given three tasks each, and they indicated the Features of Web pages that they used when deciding about the usefulness of the pages in relation to the tasks. These tasks were presented within the context of a simulated work-task situation. We investigated the relative utility of features identified by participants (Web page content, structure, and quality) and how the importance of these features is affected by the type of information-seeking task performed and the stage of the search. The results of this study provide a set of criteria used by searchers to decide about the utility of Web pages for different types of tasks. Such criteria can have implications for the design of systems that use or recommend Web pages.

    Abstract
    With the rapid diffusion of the Internet, researchers, policy makers, and users have raised concerns about online privacy, although few studies have integrated aspects of usage with psychological and attitudinal aspects of privacy. This study develops a model involving gender, generalized self-efficacy, psychological need for privacy, Internet use experience, Internet use fluency, and beliefs in privacy rights as potential influences on online privacy concerns. Survey responses from 413 college students were analyzed by bivariate correlations, hierarchical regression, and structural equation modeling. Regression results showed that beliefs in privacy rights and a psychological need for privacy were the main influences on online privacy concerns. The proposed structural model was not well supported by the data, but a revised model, linking self-efficacy with psychological need for privacy and indicating indirect influences of Internet experience and fluency on online privacy concerns about privacy through beliefs in privacy rights, was supported by the data.

    Abstract
    Users move from one state (or task) to another in an information system's labyrinth as they try to accomplish their work, and the amount of time they spend in each state varies. This article uses continuous-time stochastic models, mainly based on semi-Markov chains, to derive user state transition patterns (both in rates and in probabilities) in a Web-based information system. The methodology was demonstrated with 126,925 search sessions drawn from the transaction logs of the University of California's MELVYL® library catalog system (www.melvyLucop.edu). First, user sessions were categorized into six groups based on their similar use of the system. Second, by using a three-layer hierarchical taxonomy of the system Web pages, user sessions in each usage group were transformed into a sequence of states. All the usage groups but one have third-order sequential dependency in state transitions. The sole exception has fourth-order sequential dependency. The transition rates as well as transition probabilities of the semi-Markov model provide a background for interpreting user behavior probabilistically, at various levels of detail. Finally, the differences in derived usage patterns between usage groups were tested statistically. The test results showed that different groups have distinct patterns of system use. Knowledge of the extent of sequential dependency is beneficial because it allows one to predict a user's next move in a search space based on the past moves that have been made. It can also be used to help customize the design of the user interface to the system to facilitate interaction. The group CL6 labeled "knowledgeable and sophisticated usage" and the group CL7 labeled "unsophisticated usage" both had third-order sequential dependency and had the same most-frequently occurring search pattern: screen display, record display, screen display, and record display. The group CL8 called "highly interactive use with good search results" had fourth-order sequential dependency, and its most frequently occurring pattern was the same as CL6 and CL7 with one more screen display action added. The group CL13, called "known-item searching" had third-order sequential dependency, and its most frequently occurring pattern was index access, search with retrievals, screen display, and record display. Group CL14 called "help intensive searching," and CL18 called "relatively unsuccessful" both had thirdorder sequential dependency, and for both groups the most frequently occurring pattern was index access, search without retrievals, index access, and again, search without retrievals.

    Abstract
    In this paper, we report on the second part of an empirical study designed to observe how users interact with World Wide Web resources. Applying a holistic approach, the researches examine users' cognitive, affective, and physical behaviors during user-Web interaction in order to understand better the nature of information retrieval on the Web, the needs of Web users, and the problem-solving strategies Web users employ. From analyses and the participant verbalizations collected during monitored searches, the researchers developed a taxonomy of problem solving strategies. The coding scheme was developed based on a content analysis of the integrated process data. Information from triangulation follow-up with participants via anonymously completed questionnaires, the taxonomy, and analyses of search transcripts were collected to determine 1) what problems users encountered during the interaction and how users solved these problems; and 2) which problem-solving strategies Web users considered and selected for finding factual information. The focus of the coding was on the participants' cognitive, affective, and physical behaviors in response to the components of the problems encountered, which included problems of the following types: Web interfaces, users' mental models, and the Web information sources. Searching behavior and problem-solving patterns are described and interpreted within the relevant situational context and the problems users encountered are identified and analyzed. Both the problems users faced and their problem-solving approaches endeavored evidence a strong reliance on mental models of the features available on sites, the location of those features, and other interface design concepts

    Abstract
    Web links have been studied by information scientists for at least six years but it is only in the past two that clear evidence has emerged to show that counts of links to scholarly Web spaces (universities and departments) can correlate significantly with research measures, giving some credence to their use for the investigation of scholarly communication. This paper reports an a study to investigate the factors that influence the creation of links to journal Web sites. An empirical approach is used: collecting data and testing for significant patterns. The specific questions addressed are whether site age and site content are inducers of links to a journal's Web site as measured by the ratio of link counts to Journal Impact Factors, two variables previously discovered to be related. A new methodology for data collection is also introduced that uses the Internet Archive to obtain an earliest known creation date for Web sites. The results show that both site age and site content are significant factors for the disciplines studied: library and information science, and law. Comparisons between the two fields also show disciplinary differences in Web site characteristics. Scholars and publishers should be particularly aware that richer content an a journal's Web site tends to generate links and thus the traffic to the site.
