Process modelling has seen widespread acceptance, particularly in large IT-enabled Business Process Re engineering projects. It is applied, as a process design and management technique, across all lifecycle phases of a system. While there has been much research on alternative process modelling techniques, little attention has been focused on post-hoc evaluation of process modelling success. Thi...

Performance modelling is simulation of the user inputs and then altering the systems' configuration in order to monitor performance of software. Performance modelling rarely incorporated but gradually we have realized its significance. There are various approaches for modelling and each has its own benefits and hindrances. Performance modelling when applied on the cloud is again a very cha...

A user-centred design approach in combination with a tool-supported development of abstract prototypes is proposed. Based on task, object and user models an editor for modelling the navigation structure of a user interface as a dialogue graph is demonstrated. This editor is based on the XIML technology and allows simulations considering temporal relations between task and design decisions for t...

The Rational Unified Process (RUP) is a use case driven iterative software engineering process User Interface design within the RUP involves user interface modelling and user interface prototyping. This paper describes two support artefacts extended tabular use cases and UI element clusters which provide a bridge between these two activities. They provide support for ‘flow of events’ storyboard...

An adaptive educational system is a Web-based hypermedia system that incorporates complex intelligent tutoring techniques, which enable the system to recognize an individual user, their needs and consequently adapt the instructional sequence. The system builds on the concept domain model and includes the elements of knowledge uncertainty in the process of user modelling. The personalization is ...

This paper shows how user modelling can improve the anaphoric utterances generated by a dialogue system. Two kinds of anaphora are examined: contextual ellipsis and the anaphoric use of singular definite noun phrases. In connection with ellipsis generation, anticipation of the way in which the user would be likely to reconstruct a given utterance can help to ensure that the system's utterances ...

This paper aims to introduce the bxModeller, an open source web-based application tool, to support a business user in the modelling of the Business Processes. The graphical notation used is Business Process Modelling Notation (BPMN), an OMG standard for processes modelling. Moreover, the tool allows to traduce Business Process Diagram in a business process execution language (XML Process Descri...

In the culture domain, questionnaires are often used to obtain profiles of users for adaptation. Creating questionnaires requires subject matter experts and diverse content, and often does not scale to a variety of cultures and situations. This paper presents a novel approach that is inspired by crowdwisdom and takes advantage of freely available structured linked data. It presents a mechanism ...

This paper discusses the Visual Information Retrieval (VIR) process and emphasizes the need for more natural interfaces and a better understanding of the user. The central role of user modelling and the importance of the communication channel in a VIR scenario are discussed. We identify areas of research and possible approaches for dealing with the problem of creating effective, user responsive...

This paper presents a Web-based educational hypermedia system, called ALICE, and focuses on the evaluation of its adaptive features. The system builds on the concept domain model and includes the elements of knowledge uncertainty in the process of user modelling. The two models are used for adapting system’s navigation support to an individual user; link annotation, direct guidance and link ins...
