Uncertainty in information seeking and retrieval: A study in an academic environment

This research focuses specifically on uncertainty and information seeking in a digital environment. In this research we argue that different types of uncertainty are associated with the information seeking process and that, with the proliferation of new and different search tools, sources and channels, uncertainty, positive/desirable or negative/undesirable, continues to be a significant factor in the search process. Users may feel uncertain at any stage of the information search and retrieval process and uncertainty may remain even after completion of the process resulting in what may be called persistent uncertainty. An online questionnaire was used to collect data from users in the higher education sector. There were three parts to the questionnaire focusing on: information seeking activities, information seeking problems, and access to specific information channels or sources. Quantitative analysis was carried out on the data collected through the online questionnaire. A total of 668 responses were returned from the chosen user categories of academic staff, research staff and research students. This research has shown that there are some information seeking activities and information seeking problems that are the most common causes of uncertainty among significant number of users from different disciplines, age, gender, ICT skills, etc. This is also the case with respect to access to and use of specific information sources/channels, although the degrees of uncertainty in relation are relatively small. Possible implications of this study and further research issues are indicated.     

Information retrieval performance measures for a current awareness report composition aid

This papers studies a special “small” information retrieval problem where user satisfaction only depends on the ordering of documents. We look for a retrieval performance measure applicable for this setting. We define some requirements for such a measure. We develop a theoretical ordering of all outcomes. We look at some standard and purpose-build measures and assess them against the requirements. We conclude that a linear combination of two such measures is adequate.     

Division of labour and sharing of knowledge for synchronous collaborative information retrieval

Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques.     

Collaborative information behaviour––exploring Kuhlthau’s Information Search Process model in a group-based educational setting

Though much information behaviour takes place in collaborative settings, information behaviour processes are commonly perceived and modelled by information scientists as individual processes. The paper presents and discusses the findings from a qualitative preliminary case study exploring Kuhlthau’s Information Search Process (ISP) model in a group-based educational setting. The aim of the study was to explore if members of a group behave differently from the individual modelled in the ISP model and further, if members of a group demonstrate different behaviours or they will assimilate and turn the group into ‘an individual’, just in another sense. During a project assignment, which lasted seven weeks, two groups of information science students filled out a questionnaire and kept diaries of their activities and information-related behaviour. Further, the students were interviewed three times each during the study.     

Characterising and evaluating information seeking behaviour in a digital environment: Spotlight on the ‘bouncer’

The paper delineates and explains an emerging, but significant, form of digital information seeking behaviour among information consumers, which the authors have called ‘bouncing’. The evidence for this behaviour has emerged from five years of deep log analysis studies – an advanced form of transaction log analysis – of a wide range of users of digital information resources. Much of the evidence and discussion provided comes from the scholarly communication field. Two main bouncing metrics were applied in the log studies: site penetration, which is the number of items or pages viewed in a session, and return visits. The evidence shows that (1) a high proportion of people view just a few items or pages during a visit to a site and, (2) a high proportion of visitors either do not come back to the site or they did so infrequently. Typically those who penetrated a site least tended to return the least frequently. These people are termed ‘bouncers’. They bounce into the site and then bounce out again, presumably, to another site, as a high proportion of them do not appear to come back again. Possible explanations – negative and positive, for the form of behaviour are discussed.     

Exploring and modelling elements of information management that contribute towards making positive impacts: An outcome based approach for senior managers in a local government setting

This paper reports on the first stage of an investigation into monitoring and evaluating the impact of information management (IM) within a local government context. The overall study will utilise a combination of principles from various results-based, outcomes-based and social change approaches (Logical Framework Analysis, Most Significant Change, and Outcomes Mapping) in an attempt to move Leicestershire County Council away from a culture focused on traditional performance measurement, i.e. percentage change in use of services provided to the public, to something of real value. Interviews with 20 senior managers highlighted the important IM issues for Leicestershire County Council as a local government. These initial findings showed that maintaining high quality, trusted, and governed information and knowledge resources were of great value to the organisation. Analysis showed that 85% of senior managers interviewed considered IM to be “critical” in the achievement of organisational outcomes. Further analysis enabled the development of an initial framework indicating key areas where IM can have impact. These key areas will become the focus of further research, where applying a combination of approaches aforementioned will define the boundary partners, their specific outcomes and progress markers with possible impacts proposed. This detail will help to develop a framework for measuring the impact of IM.
