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.

Abstract

Based on a review of constructs that have been the subject of both educational and information science research, a model of learning-related information behaviour is developed. The model details components of such behaviour, including: basic information processes, information processing types and information processing approaches; and factors affecting information behaviour relating to educational environments (in particular, learning objectives) and mental (including cognitive and affective) states. The complexity of information needs and associated relevance judgements implied by the model are discussed, as are implications for the provision of cognitively and affectively ergonomic access to information, and for research into learning-related information behaviour.

Abstract

This article reports the results of a study of the role of individual differences in Internet searching. The dimensions of individual differences forming the focus of the research consisted of: cognitive styles; levels of prior experience; Internet perceptions; study approaches; age; and gender. Sixty-nine Masters students searched for information on a prescribed topic using the AItaVista search engine. Results were assessed using simple binary relevance judgements. Factor analysis and multiple regression revealed interesting differences, retrieval effectiveness being linked to: male gender; low cognitive complexity; an imager (as opposed to verbalizer) cognitive style; and a number of Internet perceptions and study approaches grouped here as indicating low self-efficacy. The implications of these findings for system development and for future research are discussed.

Abstract

This is the second of two articles published in this issue of JASIST reporting the results of a study investigating relationships between Web search strategies and a range of human individual differences. In this article we provide a combined analysis of the factor analyses previously presented separately in relation to each of three groups of human individual difference (study approaches, cognitive and demographic features, and perceptions of and approaches to Internet-based information seeking). It also introduces two series of regression analyses conducted an data spanning all three individual difference groups. The results are discussed in terms of the extent to which they satisfy the original aim of this exploratory research, namely to identify any relationships between search strategy and individual difference variables for which there is a prima facie case for more focused systematic study. It is argued that a number of such relationships do exist. The results of the project are summarized and suggestions are made for further research.

Abstract

Although much previous research has considered how we read, less attention has been paid to why we read, and the influence not only of individual or text-related factors on a reader's intention to read, but also of broader societal factors. This article presents a novel, empirically-based model of fiction reading in a public library context, taking into account the characteristics differentiating the readers of individual fiction genres. It begins with a literature review of factors motivating a reading choice or habit, and of the effects of reading different fiction genres, before introducing three previous studies by the first author into readers' attitudes towards, and engagement with, fiction and selected fiction genres. The methodologies are then summarized both for the three previous studies and the present study. The authors present a combined analysis that integrates the findings of the previous studies in order to generate a new, evidence-based model for the reading of fiction genres. Incorporating both demographic and motivational aspects, this model illustrates how the broad themes of the fiction reader profile interrelate, giving them a new causal ordering. Finally, there is a discussion of the implications of this work for library and information science research and practitioner communities.

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

In "Part 2. Uncertainty and Its Correlates,'' where Wilson is the primary author, after a review of uncertainty as a concept in information seeking and decision research, it is hypothesized that if the Kuhlthau problem solving stage model is appropriate the searchers will recognize the stage in which they currently are operating. Secondly to test Wilson's contention that operationalized uncertainty would be useful in characterizing users, it is hypothesized that uncertainty will decrease as the searcher proceeds through problem stages and after the completion of the search. A review of pre and post search interviews reveals that uncertainty can be operationalized, and that academic researchers have no difficulty with a stage model of the information seeking process. Uncertainty is unrelated to sex, age, or discipline, but is related to problem stage and domain knowledge. Both concepts appear robust.

Abstract

This article reports on the development of a novel method for the analysis of Web logs. The method uses techniques that look for similarities between queries and identify sequences of query transformation. It allows sequences of query transformations to be represented as graphical networks, thereby giving a richer view of search behavior than is possible with the usual sequential descriptions. We also perform a basic analysis to study the correlations between observed transformation codes, with results that appear to show evidence of behavior habits. The method was developed using transaction logs from the Excite search engine to provide a tool for an ongoing research project that is endeavoring to develop a greater understanding of Web-based searching by the general public.

Abstract

As digital libraries become a major source of information for many people, we need to know more about how people seek and retrieve information in digital environments. Quite commonly, users with a problem-at-hand and associated question-in-mind repeatedly search a literature for answers, and seek information in stages over extended periods from a variety of digital information resources. The process of repeatedly searching over time in relation to a specific, but possibly an evolving information problem (including changes or shifts in a variety of variables), is called the successive search phenomenon. The study outlined in this paper is currently investigating this new and little explored line of inquiry for information retrieval, Web searching, and digital libraries. The purpose of the research project is to investigate the nature, manifestations, and behavior of successive searching by users in digital environments, and to derive criteria for use in the design of information retrieval interfaces and systems supporting successive searching behavior. This study includes two related projects. The first project is based in the School of Library and Information Sciences at the University of North Texas and is funded by a National Science Foundation POWRE Grant <http://www.nsf.gov/cgi-bin/show?award=9753277>. The second project is based at the Department of Information Studies at the University of Sheffield (UK) and is funded by a grant from the British Library <http://www.shef. ac.uk/~is/research/imrg/uncerty.html> Research and Innovation Center. The broad objectives of each project are to examine the nature and extent of successive search episodes in digital environments by real users over time. The specific aim of the current project is twofold: * To characterize progressive changes and shifts that occur in: user situational context; user information problem; uncertainty reduction; user cognitive styles; cognitive and affective states of the user, and consequently in their queries; and * To characterize related changes over time in the type and use of information resources and search strategies particularly related to given capabilities of IR systems, and IR search engines, and examine changes in users' relevance judgments and criteria, and characterize their differences. The study is an observational, longitudinal data collection in the U.S. and U.K. Three questionnaires are used to collect data: reference, client post search and searcher post search questionnaires. Each successive search episode with a search intermediary for textual materials on the DIALOG Information Service is audiotaped and search transaction logs are recorded. Quantitative analysis includes statistical analysis using Likert scale data from the questionnaires and log-linear analysis of sequential data. Qualitative methods include: content analysis, structuring taxonomies; and diagrams to describe shifts and transitions within and between each search episode. Outcomes of the study are the development of appropriate model(s) for IR interactions in successive search episodes and the derivation of a set of design criteria for interfaces and systems supporting successive searching.

Abstract

Virtual environments enable a given information space to be traversed in different ways by different individuals, using different routes and navigation tools. However, we urgently need robust user models to enable us to optimize the deployment of such facilities. Research into individual differences suggests that the notion of cognitive style may be useful in this prcess. Many such styles have been identified. However, it is argued that Pask's work on holist and serialist strategies and associated styles of information processing are particularly promising in terms of the development of adaptive information systems. These constructs are reviewed, and their potential utility in 'real-world' situations assessed. Suggestions are made for ways in which they could be used in the development of virtual environments capable of optimizing the stylistic strengths and complementing the weaknesses of individual users. The role of neural networks in handling the essentially fuzzy nature of user models is discussed. Neural networks may be useful in dynamically mapping users' navigational behavior onto user models to anable them to generate appropriate adaptive responses. However, their learning capacity may also be particularly useful in the process of improving systems performance and in the cumulative development of more robust user models

Abstract

Research into information retrieval (IR) cannot yet answer the basic question of how we can design IR systems to help people search for information with optimal levels of effectiveness. In relation to human-system interaction, we have failed to develop any valid and at the same time robust user models capable of driving practical system development. If we strip away assumptions and over-optimism relating to the generalisability of what are essentially sporadic and fragmented research efforts, the great "darkness to light" ratio characterising our knowledge of human aspects of IR becomes apparent. From a more critical and pessimistic (but by no means less realistic) perspective, we are getting nowhere fast. A range of strategies is proposed to improve the situation by supporting relatively "horizontal" as well as "vertical" knowledge integration. These consist of: greater use of pluralistic research approaches; enhanced access to research data; more multidisciplinary and multi-perspective integrative reviews and conceptual mappings; and establishing a greater critical mass of published research findings sufficient to support the generation of a less sparse and fragmented evidence-based knowledge map. The potential of electronic publishing and data access for helping achieve these goals is discussed.

Abstract

Purpose - The purpose of this paper is to report research that sought to understand the requirements of information systems designed to support people engaged in creative intellectual activity. The research aimed to provide empirical evidence based on a case study of a particular arena of creativity, namely electro-acoustic music composition. However, it also sought to identify issues that may apply more widely to other arenas of human creativity. Design/methodology/approach - The research was based on a related series of three in-depth studies of electro-acoustic music composers at work. These studies entailed the collection of qualitative data from interviews, observations and "think aloud" protocols. These data were analysed inductively to reveal concepts and relationships that formed the basis for a model of interactions between the composers and the information systems with which they were working. Findings - The paper presents a model of relationships between information system features and use, and the resulting effects in terms of the extent to which creativity was perceived by the composers to have been facilitated and inhibited. In particular, a number of tensions were identified which suggest that conventional "best practice" in the design of data-intensive information systems may be fundamentally at odds with the requirements of such systems to support important aspects of creativity. Research limitations/implications - The limitations associated with in-depth qualitative research based on small samples is acknowledged, relating in particular to its lack of ability to generalise on the basis of statistical probability. However, such an approach arguably offers the complementary strength of being particularly suited to exploratory research aimed essentially at charting new territory and identifying rich and possibly unanticipated constructs rather than testing hypotheses based on existing theory. The resultant findings, however, must remain tentative and provisional pending further systematic investigation designed to establish the extent to which they are generalisable. Practical implications - As well as identifying limitations in conventional approaches to designing data-intensive information systems, an alternative architecture is proposed which seeks better to map onto the requirements of creativity support. It is hoped that both the criticisms of conventional approaches and the proposed novel architecture may be of practical use to those engaged in the design of data-intensive creativity support systems. Originality/value - The research reported here offers a novel perspective on the design of information systems in that it identifies a tension between conventional "best practice" in system design and the requirements of important aspects of creativity support. It has the advantage of being based on the in-depth observation of real composers in action over protracted periods of time. It also proposes a novel system architecture which seeks to avoid reduce such tensions.
