Abstract

Purpose - The purpose of this paper is to specify user-defined relevance criteria by which people select hyperlinks and pages in web searching. Design/methodology/approach - A quantitative and qualitative analysis was undertaken of talking aloud data from nine web searches conducted about self-generated topics. Findings - Altogether 18 different criteria for selecting hyperlinks and web pages were found. The selection is constituted, by two, intertwined processes: the relevance judgment of hyperlinks, and web pages by user-defined criteria, and decision-making concerning the acceptance or rejection of hyperlinks and web pages. The study focuses on the former process. Of the individual criteria, specificity, topicality, familiarity, and variety were used most frequently in relevance judgments. The study shows that despite the high number of individual criteria used in the judgments, a few criteria such as specificity and topicality tend to dominate. Searchers were less critical in the judgment of hyperlinks than deciding whether the activated web pages should be consulted in more detail. Research limitations/implications - The study is exploratory, drawing on a relatively low number of case searches. Originality/value - The paper gives a detailed picture of the criteria used in the relevance judgments of hyperlinks and web pages. The study also discusses the specific nature of criteria used in web searching, as compared to those used in traditional online searching environments.

Abstract

Purpose - The purpose of this paper is to elaborate how source preference criteria are defined in the context of everyday projects that require the seeking of problem-specific information. More specifically, to find out how information seekers explain their preference criteria by characterizing the perceived strengths and weaknesses of diverse sources. Design/methodology/approach - The approach takes the form of qualitative content analysis of empirical data gathered by semi-structured interviews with 16 prospective home buyers in 2008. The source preference criteria were elicited by making use of the construct of information source horizon. Findings - Networked sources were favoured most strongly, followed by printed media, human sources and organizational sources. Content of information was the primary source preference criterion. Availability of information was a fairly important criterion, while user characteristics, usability of information and situational factors were fairly marginal in this regard. In the definition of the preference criteria, more emphasis was placed on the perceived strengths than weaknesses of sources. Positive qualities such as "provides updated information" were referred to particularly while judging the relevance of the networked sources. Negative qualities like "outdated information" were primarily associated with printed media and organizational sources. Research limitations/implications - The study is exploratory, drawing on a relatively small sample recruited through a web-based service. Thus, the findings cannot be generalized to prospective home buyers. Practical implications - Prospective home buyers tend to favour web-based information sources and services. They should provide the customers with detailed information about the property, including photos. Originality/value - The paper specifies the picture of user-defined relevance judgment in the context of everyday life information seeking.

Abstract

The author reflects the conceptual and practical questions of network competence in the context of information seeking. Network competence is seen as one of the information-related competences and is defined as the mastery of four major areas: knowledge of information resources available on the Internet, skilled use of the ICT tools to access information, judgment of the relevance of information, and communication. Drawing on the ideas of the social cognitive theory developed by Albert Bandura, a model of network competence is introduced in order to discuss network competence "in action". In the model, network competence is put in practical context by relating five major factors: network competence, self-efficacy, outcome expectations, affective factors such as anxiety, and experiences received from information seeking on the Internet. Particular attention is devoted to the connections between network competence and self-efficacy which denote a person's judgment of his or her ability to organize and execute action, such as finding information on the Web.

Abstract

Drawing on the ideas of process philosophy, this study elaborates the nature of information-seeking process by approaching them as temporal developments. To this end, a conceptual analysis was made by comparing key models which approach information seeking as stage-based and cyclic processes. The nature of such processes was scrutinized by devoting attention to two main aspects, that is, the temporal order in which the constituents of information seeking appear during the process, and the changes occurring in the constituents. Stage-based approaches draw on linear time concept by conceptualizing such processes as sets of consecutive activities progressing toward a final point. Cyclic approaches conceptualize information-seeking processes as sets of iterative activities which may be repeated. The findings suggest that stage-based and cyclic approaches should not be opposite approaches; rather, they complement each other. However, cyclic models emphasizing the importance of feedback loops have gained more popularity in the modeling of web searching, whereas the interest in the development of stage-based approaches has decreased since the 1990s.

Abstract

This article elaborates the picture of information use from the perspective of interpreting informational cues about the attributes of entities. It is assumed that such activity draws on cognitive mechanisms that are employed as the constituents of diverse interpretation approaches to informational cues. The empirical data of the study were gathered by means of think aloud method from 16 prospective homebuyers in 2008. The participants interpreted informational cues available in announcements published in a printed housing listing issue and a Web-based information system serving the needs of prospective homebuyers. The data were examined by means of qualitative content analysis. By drawing on the findings of Zhang and her associates, the study revealed 7 cognitive mechanisms: identification of key attributes, specification, evaluation, comparison by similarity, comparison by differentiation, explanation, and conclusion. Three major approaches employed in the interpetation of informational cues were identified. The descriptive-evaluative approach draws on the identification and evaluation of individual attributes of an entity. The comparative approach is more sophisticated because it is based on the evaluation of the attributes by their perceived similarity or differentiation. Finally, the explanatory approach draws on the identification of attributes with causal potential.

Abstract

Purpose Arts-informed, visual research was conducted to document the pictorial metaphors that appear among original drawings of information. The purpose of this paper is to report the diversity of these pictorial metaphors, delineate their formal qualities as drawings, and provide a fresh perspective on the concept of information. Design/methodology/approach The project utilized pre-existing iSquare drawings of information that were produced by iSchool graduate students during a draw-and-write activity. From a data set of 417 images, 125 of the strongest pictorial metaphors were identified and subjected to cognitive metaphor theory. Findings Overwhelmingly, the favored source domain for envisioning information was nature. The most common pictorial metaphors were: Earth, web, tree, light bulb, box, cloud, and fishing/mining, and each brings different qualities of information into focus. The drawings were often canonical versions of objects in the world, leading to arrays of pictorial metaphors marked by their similarity. Research limitations/implications Less than 30 percent of the data set qualified as pictorial metaphors, making them a minority strategy for representing information as an image. The process to identify and interpret pictorial metaphors was highly subjective. The arts-informed methodology generated tensions between artistic and social scientific paradigms. Practical implications The pictorial metaphors for information can enhance information science education and fortify professional identity among information professionals. Originality/value This is the first arts-informed, visual study of information that utilizes cognitive metaphor theory to explore the nature of information. It strengthens a sense of history, humanity, nature, and beauty in our understanding of information today, and contributes to metaphor research at large.

Abstract

Purpose The purpose of this paper is to elaborate the picture of strategies for information searching and seeking by reviewing the conceptualizations on this topic in the field of library and information science (LIS). Design/methodology/approach The study draws on Henry Mintzberg's idea of strategy as plan and strategy as pattern in a stream of actions. Conceptual analysis of 57 LIS investigations was conducted to find out how researchers have approached the above aspects in the characterizations of information search and seeking strategies. Findings In the conceptualizations of information search and information seeking strategies, the aspect of strategy as plan is explicated most clearly in text-book approaches describing the steps of rational web searching. Most conceptualizations focus on the aspect of strategy as pattern in a stream of actions. This approach places the main emphasis on realized strategies, either deliberate or emergent. Deliberate strategies indicate how information search or information seeking processes were oriented by intentions that existed previously. Emergent strategies indicate how patterns in information seeking and seeking developed in the absence of intentions, or despite them. Research limitations/implications The conceptualizations of the shifts in information seeking and searching strategies were excluded from the study. Similarly, conceptualizations of information search or information retrieval tactics were not examined. Originality/value The study pioneers by providing an in-depth analysis of the ways in which the key aspects of strategy are conceptualized in the classifications and typologies of information seeking and searching strategies. The findings contribute to the elaboration of the conceptual space of information behaviour research.
