End User Programming, Modelling and the Semantic Web

This diagram shows the research direction this thesis moved in over time.

• End-user programming for modelling. Research began with examining programming needs of users (mainly engineers at Airbus and later Rolls-Royce aerospace companies).
• Modelling – Next, models were created to cater for the engineers needs for prediction and decision support; so the concentration was mainly on modelling.
• Semantic Web for modelling. Once the models became more complex and numerous, the collaboration necessary required a more systematic infrastructure, so Semantic Web and ontology research assisted with this.
• Semantic Web for end-user programming. Once an infrastructure was prototyped it was possible to research how this could enable construction of programs based on the Semantic Web/ontology infrastructure.
• Programs created using the semantic web infrastructure and visual diagrammatic programming were tested for modelling capability.

Research Direction Spiral

By the end of this research it was perceived that this particular combination as indicated by the mid point of the yellow section was currently under researched by the wider community.

Semantic Web and End-User Programming

Semantic Web research is not an end in itself as without the combination with End-User Programming/Modelling in order that people can create programs; there is insufficient incentive for creation and use of Semantic Web information. The reverse of this combination is that end-user modelling/programming is not practical without creation and use of structured information available through an accessible interface, such as representations using the Semantic Web.

My Research Area

The representation of program structure also needs to be visualised to End-User Programmers so they can create and edit content.

In order to increase the use of Semantic Web technologies it is necessary to create applications that make use of the Semantic Web for practical applications. Enabling modelling with Semantic Web technologies could encourage domain experts to fill ontologies with useful information, so generating more benefit from their use.

Research Development

It is important to enable changes to the design of the information source and its structure as necessary, even when it contains information. This makes possible continuous improvement of the information and its representation together. Clear visualisation of the structure makes out of date and duplicate information obvious, so it can be changed by the end-users of the information. This provides for maintenance of information quality without necessitating end-users to understand relational database design; though relational databases can still be used for information where the frequency of structural change is less.

The diagrams below shows the way iterative development is used both in this research and in the implementation to ensure that changes can be made systematically as necessary and without disrupting the project.
