Model-Driven Development (MDD) has encouraged the use of automated software tools that facilitate the development process from modelling to coding. User Interfaces (UI), as a significant part of most applications, should also be modelled using a MDD perspective. This paper presents an Eclipse GMF tool for modelling user-interaction diagrams –an specialization of the UML state-machines for UI de...

User modelling is fast becoming a major topic for commercial and academic research. A major problem in user modelling is in categorising a new user into known user classes. In this paper we consider user classification as a recognition problem where a new user is an uncertain object of undetermined class and we must determine the membership of the object in each of a number of prototypical user...

Automatic structuring is one means to ease access to document collections, be it for organization or for exploration. Of even greater help would be a presentation that adapts to the user’s way of structuring and thus is intuitively understandable. We extend an existing useradaptive prototype system that is based on a growing self-organizing map and that learns a feature weighting scheme from a ...

This paper discusses the extension of the Unified Modelling Language (UML) for modelling tasks and user groups. The term task is used widely, to include collaborative and multi-user tasks and without reference to some specific theory of user task knowledge or behaviour. The paper presents the proposed extension to the UML, focusing on the concepts involved and the abstract syntax for the notati...

User modelling and personalisation are the key aspects of recommender systems in terms of recommendation quality. While being very efficient and designed to work with huge amounts of data, present recommender systems often lack the facility of user integration when it comes to feedback and direct user modelling. We propose the introduction of dynamic logic programming – an extension of answer s...

Queueing Modelling is proposed in the domain of Intelligent User Interfaces and, more generally, in the field of Human-Computer Interaction. It is argued that Queueing Modelling can facilitate assessment of the current state and prediction of the future behaviour of user-computer interaction. This assessment can be used as the basis for adaptations either at design-time or at run-time, and can ...

User-adapted interaction has been a research goal for many years now. In research on natural-language dialog systems, user models were introduced as explicit representation of assumptions about the individual characteristics of users. Systems would consult these models to decide how to adapt their behaviour to each user. Traditional user models contain mentalistic assumptions (MA), i.e., assump...

An agenda for modelling knowledge is set down. We argue that for PUM a model that allows for less than perfect behaviour is required. Gärdenfors’ [3] approach is looked at and we explain why we consider that the notion of rationality that underlies Gärdenfors’ approach is too strict for our purposes. It is suggested how we can import epistemic logics based on local reasoning and explicit and im...

The paper presents a proposal of a method for MDA based “on-the-fly” modelling of Musical Real Time Applications. The method is based on use of the Executable and Translatable UML approach (xtUML) with regards to implementation on embedded systems. Since the goal is to implement a real-time application requiring certain real-time Quality of Service (QoS) properties, the real-time response requi...
