A commercial system under development, the Tax and Investment Management Strategizer (TIMS), has an identified need for a user modelling component to address the complexity issues inherent in real life knowledge-based systems. We propose a pragmatic user modelling componentusing mainly existing technology that provides support for the users, particularly the novice TIMS users and novice Financi...

The paper presents research on user modelling for an in-car spoken dialogue system, including the implementation of a generic user modelling module applied to the modelling of drivers’ task objectives.

The design options in resolving heterogeneous data source access from a single query, and for a supporting user modelling component are discussed. The MIPS system is used as an example to consider the role of user modelling in automatically generating hypermedia presentations of the information retrieved from such distributed data sources whose semantics are unknown to its users. A user modelli...

User Modelling is the core component for the majority of personalisation systems. By keeping a model for every user, a system can successfully personalise its content and utilise available resources accordingly. While researching the literature, one can recognize the importance of achieving interoperability across various platforms and systems while attempting to personalise a large diversity o...

As User Modelling moves away from a tightly integrated adjunct of adaptive systems and into User Modelling Services provision, it is important to consider what facets or characteristics of a user might need to be contained within a user model in order to support particular functions. Here we examine previous mechanisms for creating a metacognitive user model. We then take first steps to describ...

Web-based information systems (WBIS) include the website part and the system part, and easy-to-use website is particular critical to the success of WBIS. This paper argues that the easy-to-use website can only be developed based on the need of use in the user perspective and such need must be captured and modelled as communicational requirements in WBIS analysis. However current analysis and mo...

User response to contributed content in online social media depends on many factors. These include how the site lays out new content, how frequently the user visits the site, how many friends the user follows, how active these friends are, as well as how interesting or useful the content is to the user. We present a stochastic modeling framework that relates a user’s behavior to details of the ...

This paper reports experiments demonstrating that the extent to which subjects ascribe emotions to VR faces is highly dependent on textures applied to the face. We demonstrate this for both a photo-realistic vs. non-photo-realistic texture pair and for a male vs. female texture pair. In both cases, experiments were conducted over the Internet on still frames taken from a well-controlled VR emot...
