This paper presents a user interface to the User-Centred Knowledge Model (t-UCK). T-UCK is a knowledge modelling tool for designing knowledge-intensive systems. The model centres round the various users, i.e., both the design users and the end users, and facilitates the use of a conceptual model for handling different types of knowledge, the reasoning strategy and other functionality. For the d...

The Unified Modeling Language (UML) can be used for modelling both the structure and behaviour of software applications. However, although UML supports many different modelling notations, minimal support is provided for user interface (UI) design. The Unified Modeling Language for Interactive Applications (UMLi) is an extension of UML that provides support for UI design. UMLi has a user interfa...

Modelling and version control both play key roles in industrial-scale software development, yet their integration has proved difficult. Significant effort has been expended on improving file-based merging of modellers’ work, but empirical research shows the results of that approach still leave much to be desired in practice. Approaches based on multi-user modelling databases have often foundere...

Mind-maps have been widely neglected by the information retrieval (IR) community. However, there are an estimated two million active mind-map users, who create 5 million mind-maps every year, of which a total of 300,000 is publicly available. We believe this to be a rich source for information retrieval applications, and present eight ideas on how mind-maps could be utilized by them. For instan...

The Web 2.0 infrastructure allowed for a tremendous technological growth in the ways that information is distributed and exchanged among individuals. Web sites transformed to hosts of an abundance of user generated content in various domains comprising thereafter social media platforms. This evolution heralded the beginning of a new era for user modelling. Several types of applications have gai...

Existing process modelling languages and especially executable process modelling languages are not designed for business users without programming knowledge. We therefore propose a novel Lightweight Process Modelling seeking to lower the entrance barrier for modelling executable processes. In this sense lightweight applies to the user interaction and means easy to understand in the context of t...

Process controlled systems are used for dedicated applications. Every application is the subject of special requirements enforced by the customer. Requirements modelling is an user centred activity. These systems are time critical. The requirements modelling language used must facilitate the description of temporal requirements that are meaningful for these systems, while being understandable b...

User participation in information system development is considered to be an important factor influencing implementation success or failure. The ETHICS (Effective Technical and Human Implementation of Computer-based Systems) method was developed as a guide to user involvement in system design. A case study of successful implementation which did not use the ETHICS method explicitly is described. ...

We describe the Zinc modelling language. Zinc provides set constraints, user defined types, constrained types, and polymorphic predicates and functions. The last allows Zinc to be readily extended to different application domains by user-defined libraries. Zinc is designed to support a modelling methodology in which the same conceptual model can be automatically mapped into different design mod...

This paper introduces a strategy, a user model, and a methodology for utilising adaptive hypermedia in performance support domain and specifically for fault diagnosis. This utilisation is implemented by employing task-specific and user-centred hypermedia which allows supporting content to be synchronized with the diagnostic expert system inference process. A stereotype user model is suggested i...
