This chapter focuses on the role of user models and user modelling for enhanced, personalised user support within knowledge management systems (KMSs). Personalisation can bring a utility function as well as a conviviality function with “high touch” impact for the users. From this utility and conviviality perspective, various personalised services enable KMSs to adapt their functionality, structure, and content to match the needs and preferences of users based on a user model that is stored and updated dynamically. The chapter presents a set of examples, different types of adaptations and personalised services specific to KMSs.

We propose a technique for user modeling in Adaptive Hypermedia (AH) that is unobtrusive at both the level of observable behavior and that of cognition. Unobtrusive user modeling is complementary to transparent user modeling. Unobtrusive user modeling induces user models appropriate for Educational AH (EAH) based on metaphors characterized by a shared locus of control over learning, such as small group learning. Transparent user modeling, on the other hand, induces user models appropriate for EAH based on metaphors characterized by an independent locus of control, such as social navigation. We extend an existing decomposition model of adaptation in AH to incorporate summative evaluation of unobtrusive user modeling. Summative evaluation examines the effects or outcomes of a system, while formative evaluation is used to improve a system under development. We also introduce a separate, two-stage model for formative evaluation of unobtrusive user modeling. We then present results from a field study for the first of the two developmental stages and describe the current field study of the second developmental stage. Finally, we compare unobtrusive and transparent user modeling, and explain the role of each.

The Relationship

A growing interest in the application of hypertext (hypermedia) to the task of indexing reflects the increasing availability of online electronic material (text and text/graphics/video; CD), and a recognition that considerable benefits might arise from the application of hypermedia techniques (both in academic and commercial contexts). This paper considers the relationship between indexing and hypermedia on two fronts: Conceptualizing adequate models of index structures and indexing procedures; and establishing what readers do when accessing indexes. There is a range of explicit and implicit models (or abstractions) underlying databases, documents and indexes. A fundamental starting point for the development of substructure indexing tools for use with hypermedia is the precise specification of such models. Analysis of substructure indexing models will allow the identification of largely technical constraints (fundamentally linked to the system-derived parameters of particular computing systems), and conceptual constraints (intrinsic to the ’semantics’ of indexes and indexing procedures). Related also are aspects of the problem deriving from how indexes (the electronic form) can, and should be, presented. The first part of this paper considers a framework for the identification of such models. The second aspect of the research reported here concerns index use. A field study was conducted looking at the use accountants (N = 10) make of indexing facilities in a large financial services document. Task analysis highlighted the range of problems encountered, strategies employed and the kinds of solutions arrived at. The results indicate that there are six key factors underlying the ‘rule of thumb’ procedure users employ when interrogating an index. The implication for this study for the design of indexing tools within hypermedia environment are discussed.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.
