Abstract

Purpose - The purpose of this paper is to explore the impact of a number of human individual differences on the web searching of a sample of the general public. Design/methodology/approach - In total, 91 members of the general public performed 195 controlled searches. Search activity and ratings of search difficulty and success were recorded and statistically analysed. The study was exploratory, and sought to establish whether there is a prima facie case for further systematic investigation of the selection and combination of variables studied here. Findings - Results revealed a number of interactions between individual differences, the use of different search strategies, and levels of perceived search difficulty and success. The findings also suggest that the open and closed nature of searches may affect these interactions. A conceptual model of these relationships is presented. Practical implications - Better understanding of factors affecting searching may help one to develop more effective search support, whether in the form of personalised search interfaces and mechanisms, adaptive systems, training or help systems. However, the findings reveal a complexity and variability suggesting that there is little immediate prospect of developing any simple model capable of driving such systems. Originality/value - There are several areas of this research that make it unique: the study's focus on a sample of the general public; its use of search logs linked to personal data; its development of a novel search strategy classifier; its temporal modelling of how searches are transformed over time; and its illumination of four different types of experienced searcher, linked to different search behaviours and outcomes.

Abstract

The research reported here was an exploratory study that sought to discover the effects of human individual differences an Web search strategy. These differences consisted of (a) study approaches, (b) cognitive and demographic features, and (c) perceptions of and preferred approaches to Web-based information seeking. Sixtyeight master's students used AItaVista to search for information an three assigned search topics graded in terms of complexity. Five hundred seven search queries were factor analyzed to identify relationships between the individual difference variables and Boolean and best-match search strategies. A number of consistent patterns of relationship were found. As task complexity increased, a number of strategic shifts were also observed an the part of searchers possessing particular combinations of characteristics. A second article (published in this issue of JASIST; Ford, Miller, & Moss, 2005) presents a combined analyses of the data including a series of regression analyses.

Abstract

Objectivity, in the form of the application of external scrutiny according to standards agreed within a research community, is an essential characteristic of information science research whether pursued from positivist, interpretative, or action research perspectives. Subjectivity may represent both a legitimate focus of research (e.g., people's perceptions and attitudes) and a legitimate component of methodology (e.g., enabling researchers to enter, experience, and share the perceived worlds of their subjects). However, subjectivity that both (a) is not open to external scrutiny and (b) gives rise to contingent dependencies is problematic for research. The issue of problematic types of subjectivity is considered, and the contributions to the debate concerning possible solutions of two key thinkers - the cybernetician Gordon Pask and the methodological philosopher Brenda Dervin - are discussed. The need identified by Dervin for researchers to be able to escape (expose and test) their own assumptions is explored in terms of a dynamic interplay between relatively subjective and objective forces, each requiring the liberating and constraining energies of the other. The extent to which meta-methodological awareness - a prerequisite for any such escape - can be fostered, for example, by the quality of research environments, is explored along with implications for those responsible for managing and funding research.
