24Chen, A.T.: Information use and illness representations : understanding their connection in illness coping.
In: Journal of the Association for Information Science and Technology. 66(2015) no.2, S.340-353.
Abstract: According to Leventhal's Common Sense Model of illness regulation, people approach and deal with their illnesses differently depending on their cognitive representations of them. Thus, understanding people's illness representations can be invaluable when assisting them to develop lifestyle modifications that improve their health. What role does information use play in this equation? This is the crucial question addressed by this two-part study. Part 1 hypothesizes a model of how information use at different timepoints may affect illness representations, and then tests this model. The study found that a number of information use type and time pairings (e.g., information used to consult healthcare practitioners at symptom onset) were significantly associated with present-day level of personal control. The results suggest that it is not merely type or timing of information use alone that is helpful in illness coping, but the coupling of the two; this has several implications for the design of patient education programs. Part 2 examines how information use and illness representations differ based on the way an individual participates in online health forums and social media sites. The following four different participation styles were investigated: nonuser, only reading ("lurker"), posting occasionally but largely reading ("infrequent poster"), and reading and posting ("poster"). Differences in both information use and illness perceptions were found, and the implications of these are discussed.

26Mishra, J. ; Allen, D. ; Pearman, A.: Information seeking, use, and decision making.
In: Journal of the Association for Information Science and Technology. 66(2015) no.4, S.662-673.
Abstract: In this paper we explored three areas: decision making and information seeking, the relationship between information seeking and uncertainty, and the role of expertise in influencing information use. This was undertaken in the context of a qualitative study into decision making in the initial stages of emergency response to major incidents. The research took an interpretive approach in which activity theory is used as an analytical framework. The research provides further evidence that the context of the activity and individual differences influence the choice of decision mode and associated information behavior. We also established that information is often not used to resolve uncertainty in decision making and indeed information is often sought and used after the decision is made to justify the decision. Finally, we point to the significance of both expertise and confidence in understanding information behavior. The contribution of the research to existing theoretical frameworks is discussed and a modified version of Wilson's problem-solving model is proposed.

27Wijnhoven, F. ; Brinkhuis, M.: Internet information triangulation : design theory and prototype evaluation.
In: Journal of the Association for Information Science and Technology. 66(2015) no.4, S.684-701.
Abstract: Many discussions exist regarding the credibility of information on the Internet. Similar discussions happen on the interpretation of social scientific research data, for which information triangulation has been proposed as a useful method. In this article, we explore a design theory-consisting of a kernel theory, meta-requirements, and meta-designs-for software and services that triangulate Internet information. The kernel theory identifies 5 triangulation methods based on Churchman's inquiring systems theory and related meta-requirements. These meta-requirements are used to search for existing software and services that contain design features for Internet information triangulation tools. We discuss a prototyping study of the use of an information triangulator among 72 college students and how their use contributes to their opinion formation. From these findings, we conclude that triangulation tools can contribute to opinion formation by information consumers, especially when the tool is not a mere fact checker but includes the search and delivery of alternative views. Finally, we discuss other empirical propositions and design propositions for an agenda for triangulator developers and researchers. In particular, we propose investment in theory triangulation, that is, tools to automatically detect ethically and theoretically alternative information and views.

Abstract: Die Suche nach Informationen in digitalen Systemen ist für viele Menschen eine Alltagstätigkeit. Dabei treten sehr viele unterschiedliche Situationen auf, in denen eine Suche durchgeführt wird. Diese Situationen haben einen Einfluss auf die jeweilige Relevanz von Inhalten und das Informationsverhalten der Nutzer. Um eine genauere Vorstellung von diesem Einfluss zu bekommen wurden zwei Studien mit Hilfe der Wikipedia durchgeführt, anhand derer das Informationsverhalten der Nutzer in den verschiedenen Situationen beobachtet und ein Zusammenhang zu den jeweiligen Einflussfaktoren hergestellt werden konnte.

31Kostagiolas, P.A. ; Lavranos, C. ; Korfiatis, N. ; Papadatos, J. ; Papavlasopoulos, S.: Music, musicians and information seeking behaviour : a case study on a community concert band.
In: Journal of documentation. 71(2015) no.1, S.3-24.
Abstract: Purpose - The purpose of this paper is to examine information seeking behaviour targeted to music information seeking by amateur musicians, accompanied with empirical evidence from a survey on a community concert band. While several studies in the literature have examined information seeking in the context of hedonic motives (e.g. entertainment oriented), music information can also be used for utilitarian purposes by providing amateur musicians the necessary tools to improve their skill and become better in their practice. Design/methodology/approach - A review of the literature on music information seeking and an empirical study on members of an amateur concert band are presented. The theoretical construct of the survey is informed by Wilsons' macro model of information seeking behaviour. This is employed in order to understand information motives and needs, as well as obstacles in information seeking of musicians. Findings - Musicians seek information not only for entertainment but for educational purposes as well as for the acquisition of certain music works. The use of the internet for information seeking as well as the gradual adoption of online social networks has provided access to new musical resources within the digital music networks. Originality/value - A person-centred approach for information seeking behaviour is studied and adapted for musicians. The survey provides new information behaviour results for designers of music information spaces which in turn are creating a new model of the relationship between music and society.
32Savolainen, R.: ¬The interplay of affective and cognitive factors in information seeking and use : comparing Kuhlthau's and Nahl's models.
In: Journal of documentation. 71(2015) no.1, S.175-197.
Abstract: Purpose - The purpose of this paper is to elaborate the conceptual picture of the relationships between the affective and cognitive factors in information seeking and use. Design/methodology/approach - Conceptual analysis focusing on the ways in which the affective and cognitive factors and their interplay are approached in the Information Search Process model developed by Carol Kuhlthau, and the Social-Biological Information Technology model elaborated by Diane Nahl. Findings - Kuhlthau's model approaches the cognitive factors (thoughts) and affective factors (feelings) and affective-cognitive factors (mood) as integral constituents of the six-stage information search process. Thoughts determine the valence of feelings (positive or negative), while mood opens or closes the range of possibilities in a search. Nahl's taxonomic model defines the affective and cognitive factors as components of a biologically determined process serving the ends of adaptation to information ecology. The interplay of the above factors is conceptualized by focusing on their mutual roles in the cognitive and affective appraisal of information. Research limitations/implications - The findings are based on the comparison of two models only. Originality/value - So far, information scientists have largely ignored the study of the interplay between affective and cognitive factors in information seeking and use. The findings indicate that the examination of these factors together rather than separately holds a good potential to elaborate the holistic picture of information seeking and use.
33Beheshti, J. ; Cole, C. ; Abuhimed, D. ; Lamoureux, I.: Tracking middle school students' information behavior via Kuhlthau's ISP Model : temporality.
In: Journal of the Association for Information Science and Technology. 66(2015) no.5, S.943-960.
Abstract: The article reports a field study investigating the temporality of the information behavior of 44 grade 8 students from initiation to completion of their school inquiry-based history project. The conceptual framework for the study is Kuhlthau's 6-stage information-search process (ISP) model. The objective of the study is to test and extend ISP model concepts. As per other ISP model studies, our study measured the evolution of the feelings, thoughts, and actions of the study participants over the 3-month period of their class project. The unique feature of this study is the unlimited access the researchers had to a real-life history class, resulting in 12 separate measuring periods. We report 2 important findings of the study. First, through factor analysis, we determined 5 factors that define the temporality of completing an inquiry-based project for these grade 8 students. The second main finding is the importance of the students' consultations with their classmates, siblings, parents, and teachers in the construction of the knowledge necessary to complete their project.

34Zhang, X. ; Liu, J. ; Cole, M. ; Belkin, N.: Predicting users' domain knowledge in information retrieval using multiple regression analysis of search behaviors.
In: Journal of the Association for Information Science and Technology. 66(2015) no.5, S.980-1000.
Abstract: User domain knowledge affects search behaviors and search success. Predicting a user's knowledge level from implicit evidence such as search behaviors could allow an adaptive information retrieval system to better personalize its interaction with users. This study examines whether user domain knowledge can be predicted from search behaviors by applying a regression modeling analysis method. We identify behavioral features that contribute most to a successful prediction model. A user experiment was conducted with 40 participants searching on task topics in the domain of genomics. Participant domain knowledge level was assessed based on the users' familiarity with and expertise in the search topics and their knowledge of MeSH (Medical Subject Headings) terms in the categories that corresponded to the search topics. Users' search behaviors were captured by logging software, which includes querying behaviors, document selection behaviors, and general task interaction behaviors. Multiple regression analysis was run on the behavioral data using different variable selection methods. Four successful predictive models were identified, each involving a slightly different set of behavioral variables. The models were compared for the best on model fit, significance of the model, and contributions of individual predictors in each model. Each model was validated using the split sampling method. The final model highlights three behavioral variables as domain knowledge level predictors: the number of documents saved, the average query length, and the average ranking position of the documents opened. The results are discussed, study limitations are addressed, and future research directions are suggested.

35Smith, C.L.: Domain-independent search expertise : a description of procedural knowledge gained during guided instruction.
In: Journal of the Association for Information Science and Technology. 66(2015) no.7, S.1388-1405.
Abstract: This longitudinal study examined the search behavior of 10 students as they completed assigned exercises for an online professional course in expert searching. The research objective was to identify, describe, and hypothesize about features of the behavior that are indicative of procedural knowledge gained during guided instruction. Log-data of search interaction were coded using a conceptual framework focused on components of search practice hypothesized to organize an expert searcher's attention during search. The coded data were analyzed using a measure of pointwise mutual information and state-transition analysis. Results of the study provide important insight for future investigation of domain-independent search expertise and for the design of systems that assist searchers in gaining expertise.

36Freund, L.: Contextualizing the information-seeking behavior of software engineers.
In: Journal of the Association for Information Science and Technology. 66(2015) no.8, S.1594-1605.
Abstract: Information seeking in the workplace can vary substantially from one search to the next due to changes in the context of the search. Modeling these dynamic contextual effects is an important challenge facing the research community because it has the potential to lead to more responsive search systems. With this motivation, a study of software engineers was conducted to understand the role that contextual factors play in shaping their information-seeking behavior. Research was conducted in the field in a large technology company and comprised six unstructured interviews, a focus group, and 13 in-depth, semistructured interviews. Qualitative analysis revealed a set of contextual factors and related information behaviors. Results are formalized in the contextual model of source selection, the main contributions of which are the identification of two types of conditioning variables (requirements and constraints) that mediate between the contextual factors and source-selection decisions, and the articulation of dominant source-selection patterns. The study has implications for the design of context-sensitive search systems in this domain and may inform contextual approaches to information seeking in other professional domains.

37Pontis, S. ; Blandford, A.: Understanding "influence" : an exploratory study of academics' processes of knowledge construction through iterative and interactive information seeking.
In: Journal of the Association for Information Science and Technology. 66(2015) no.8, S.1576-1593.
Abstract: The motivation for this study was to better understand academics' searching and sensemaking processes when solving exploratory tasks for which they lack pre-existing frames. We focus on "influence" tasks because, although they appear to be unfamiliar, they arise in much academic discourse, at least tacitly. We report the processes of academics at different levels of seniority when completing exploratory search tasks that involved identifying influential members of their academic community and "rising stars," and similarly for an unfamiliar academic community. 11 think-aloud sessions followed by semi-structured interviews were conducted to investigate the roles of specific and general domain expertise in shaping information seeking and knowledge construction. Academics defined and completed the tasks through an iterative and interactive process of seeking and sensemaking, during which they constructed an understanding of their communities and determined qualities of "being influential". The Data/Frame Theory of Sensemaking was used to provide sensitising theoretical constructs. The study shows that both external and internal knowledge resources are essential to define a starting point or frame, make and support decisions, and experience satisfaction. Ill-defined or non-existent initial frames may cause unsubstantial or arbitrary decisions, and feelings of uncertainty and lack of confidence.

38Sigaard, K.T. ; Skov, M.: Applying an expectancy-value model to study motivators for work-task based information seeking.
In: Journal of documentation. 71(2015) no.4, S.709-732.
Abstract: Design/methodology/approach An operationalisation of the model is presented based on the theory of expectancy-value and on the operationalisation used when the model was first developed. Data for the analysis were collected from a sample of seven informants working as consultants in Danish municipalities. Each participant filled out a questionnaire, kept a log book for a week and participated in a subsequent interview to elicit data regarding their information source behaviour and task motivation. Findings Motivation affected source use when the informants search for information as part of their professional life. This meant that the number of sources used and the preference for interpersonal and internal sources increased when the task had high-value motivation or low-expectancy motivation or both. Research limitations/implications The study is based on a relatively small sample and considers only one motivation theory. This should be addressed in future research along with a broadening of the studied group to involve other professions than municipality consultants. Originality/value Motivational theories from the field of psychology have been used sparsely in studies of information seeking. This study operationalises and verifies such a theory based on a theoretical adaptation of this model made by Savolainen (2012c).

39Tan, E.M.-Y. ; Goh, D.H.-L.: ¬A study of social interaction during mobile information seeking.
In: Journal of the Association for Information Science and Technology. 66(2015) no.10, S.2031-2044.
Abstract: With the increasing importance of social media in people's lives, more mobile applications have incorporated features to support social networking activities. These applications enable communication between people, using features such as chatting and blogging. There is, however, little consideration of the collaboration between people during information seeking. Mobile applications should support the seeking, sharing, confirming, and validating of information systematically to help users complete their tasks and fulfill their information needs. To support information seeking, especially collaboratively as a group, there is a need to understand people's social interaction behavior. Using tourism as a domain, we conducted a diary study to look into tourists' social interaction during information seeking. Further, based on the diary study findings and current research, we describe a set of triggers that lead to collaboration for each step in the information-seeking process. Here we present the social collaboration patterns between tourists and the people around them. Further, based on a diary study and current research, we describe a set of triggers that lead to collaboration for each step in the BIG6 information-seeking process.

40Oh, S. ; Syn, S.Y.: Motivations for sharing information and social support in social media : a comparative analysis of Facebook, Twitter, Delicious, YouTube, and Flickr.
In: Journal of the Association for Information Science and Technology. 66(2015) no.10, S.2045-2060.
Abstract: The success or failure of social media is highly dependent on the active participation of its users. In order to examine the influential factors that inspire dynamic and eager participation, this study investigates what motivates social media users to share their personal experiences, information, and social support with anonymous others. A variety of information-sharing activities in social media, including creating postings, photos, and videos in 5 different types of social media: Facebook, Twitter, Delicious, YouTube, and Flickr, were observed. Ten factors: enjoyment, self-efficacy, learning, personal gain, altruism, empathy, social engagement, community interest, reciprocity, and reputation, were tested to identify the motivations of social media users based on reviews of major motivation theories and models. Findings from this study indicate that all of the 10 motivations are influential in encouraging users' information sharing to some degree and strongly correlate with one another. At the same time, motivations differ across the 5 types of social media, given that they deliver different information content and serve different purposes. Understanding such differences in motivations could benefit social media developers and those organizations or institutes that would like to use social media to facilitate communication among their community members; appropriate types of social media could be chosen that would fit their own purposes and they could develop strategies that would encourage their members to contribute to their communities through social media.
