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

Purpose - Describes the basic premises of three metatheories that represent important or emerging perspectives on information seeking, retrieval and knowledge formation in information science: constructivism, collectivism, and constructionism. Design/methodology/approach - Presents a literature-based conceptual analysis. Pinpoints the differences between the positions in their conceptions of language and the nature and origin of knowledge. Findings - Each of the three metatheories addresses and solves specific types of research questions and design problems. The metatheories thus complement one another. Each of the three metatheories encourages and constitutes a distinctive type of research and learning. Originality/value - Outlines each metatheory's specific fields of application.

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 - 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 article is to elaborate the picture of the processes of information use by comparing conceptualizations provided by the constructivist approach and the human information processing approach. Design/methodology/approach - The article is a conceptual analysis of major articles characterizing information use and human information processing in the fields of information studies and consumer research. Findings - It is found that both research approaches share the assumption that interpreting, relating and comparing qualities of things is fundamental to the information use process. Research limitations/implications - The picture of information use processes is based on the comparison of two research approaches only. Originality/value - Compared to the numerous studies on information needs and seeking, the questions of information use have remained under-researched. The study elaborates the conceptual picture of information use processes by identifying similarities and differences between two major research approaches.

Abstract

The conceptual issues of information use are discussed by reviewing the major ideas of sense-making methodology developed by Brenda Dervin. Sense-making methodology approaches the phenomena of information use by drawing on the metaphor of gap-bridging. The nature of this metaphor is explored by utilizing the ideas of metaphor analysis suggested by Lakoff and Johnson. First, the source domain of the metaphor is characterized by utilizing the graphical illustrations of sense-making metaphors. Second, the target domain of the metaphor is analyzed by scrutinizing Dervin's key writings on information seeking and use. The metaphor of gap-bridging does not suggest a substantive conception of information use; the metaphor gives methodological and heuristic guidance to posit contextual questions as to how people interpret information to make sense of it. Specifically, these questions focus on the ways in which cognitive, affective, and other elements useful for the sense-making process are constructed and shaped to bridge the gap. Ultimately, the key question of information use studies is how people design information in context.

Abstract

The study focuses on the ways in which people define their source preferences in the context of seeking problem-specific information for non-work purposes. The conceptual framework draws on two major concepts, that is, information source horizon and information pathways. The former denotes the ways information sources are mapped in preference order in an imaginary field, while information pathways refers to the sequences in which sources placed on the information source horizon are actually used. The empirical part of the study draws on semi-structured interviews with 18 individuals active in environmental issues. Human sources and the Internet were preferred most strongly in seeking for problem-based information. The major source preferences were content of information, and availability and accessibility. Usability of information sources and user characteristics were mentioned less frequently as preference criteria. Typically, information pathways consisted of the use of 3-4 sources. On average, human and networked sources were favored in the early phases of information seeking. Printed media such as magazines and organizational sources were often used to complement information received from human sources and the Internet. However, the source preferences varied considerably, depending on the requirements of the problem at hand.

Abstract

This study focuses on the ways in which people define their source preferences in the context of seeking orienting information for nonwork purposes. The conceptual framework of the study combines ideas drawn from social phenomenology and information-seeking studies. The study utilizes Alfred Schutz's model describing the ways in which actors structure everyday knowledge into regions of decreasing relevance. It is assumed that this structuring based on the actor's interest at hand is also reflected in the ways in which an actor prefers information sources and channels. The concept of information source horizon is used to elicit articulations of source preferences. The empirical part of the study draws on interviews with 20 individuals active in environmental issues. Printed media (newspapers), the Internet, and broadcast media (radio, television) were preferred in seeking for orienting information. The major source preferences were content of information, and availability and accessibility. Usability of information sources, user characteristics such as media habits, and situational factors were mentioned less frequently as preference criteria.

Abstract

Information seeking may be analyzed in two major contexts: job-related and nonwork. The present entry concentrates on nonwork information seeking, more properly called everyday life information seeking (ELIS). Typically, ELIS studies discuss the ways in which people access and use various information sources to meet information needs in areas such as health, consumption, and leisure. The entry specifies the concept of ELIS and characterizes the major ELIS models. They include the Sense-Making approach (Dervin), the Small world theory (Chatman), the ecological model of ELIS (Williamson), ELIS in the context of way of life (Savolainen), the model of information practices (McKenzie), and the concept of information grounds (Fisher). ELIS practices tend to draw on the habitualized use of a limited number of sources which have been found useful in previous use contexts. Since the late 1990s, the Internet has increasingly affected the ELIS practices by providing easily accessible sources. Even though the popularity of the networked sources has grown rapidly they will complement, rather than replace, more traditional sources and channels.
