Test implementations assisted with :-
Providing clarity for process modelling and management, by creating a structured open standard visual modelling environment that is usable by non-programmers.
* Collaboration, dissemination, reuse and sharing of models using web applications and services.
* Enabling people to model at a high level of abstract conceptual modelling, thereby producing better process models using tools that model at domain level, rather than at code level.
* Development of Semantic Web based process modelling to provide the means for visualisation and calculation/sequencing, together with a decision support engine for model creation and retrieval.
* Increased user involvement for model development allows savings in cost and time taken for process modelling.
* Enhanced availability of process models and interactive visualisation of model results using web browser based software, this will also be an important teaching resource.
Identification of improvements to process efficiency and effectiveness.
* Better interoperability of models and ability to identify common problems missed during creation of standalone spreadsheets. Increased model detail and ease of upgrade with layered architecture of open standard languages to eliminate inconsistencies and allow better decision making.
* New ways of enabling end user interaction, with collaborative development of process models that will allow people more scope to solve problems.
*Enabling task based access to Semantic Web information, e.g. by employees and home users who have no knowledge or interest in the Semantic Web, but who will use tools for particular tasks.
This research tested first steps towards helping to solve problems caused by lack of collaborative modelling in process design. This could also bridge the gap between industry and those advocating the use of modelling/programming using Semantic Web techniques, to improve efficiency and effectiveness.
This research has potential benefit for any problem where end user programming using Semantic Web technology is applicable. This is a very broad range, involving most modelling. The particular areas where the research is most transferable are manufacturing and business modelling, e-learning and provision of models for public understanding of science and engineering, and health and science taxonomy/ontology management.
The research in this field has reinforced the view that Semantic Web based process modelling is an appropriate and robust means of achieving end user objectives. If domain experts are not involved in creation of the model, there is no proper way for the knowledge they are encoding to emerge, or for proper collaboration. This is necessary as each expert is best focused on encapsulating the part of the model that they are most expert in. People need to be involved in model creation if they are to understand the model, decision, and how the decision was made. So there is a need for end user modelling/programming to enable this. Full automation hinders user involvement and traceability, so semi-automated systems that interact with end users and assist with all stages of the model decision are better. If a person goes straight to the answer how can it be expected that they fully understood the question?
Breaking complex mathematics into modularised traceable steps eases management of it, and visualisation, and allows modelling of different scenarios, and these scenarios demonstrate the emergent properties of the model, enabling decision support. BiDirectional Traceability is needed, traceability between nodes/sub-models, and between models, and between suppliers and buyers.
The research made some progress towards allowing end users to concentrate on the domain to be modelled rather than on computing technologies. This research can enable collaborative modelling and interaction, via applying end user programming techniques to enable domain experts such as engineers and business people to create and interact with the knowledge representation themselves, and co-operate to ensure the representations are useful for addressing their problems, with less software creation barriers. Software developers need to enable such systems to make this all possible.
Existing ontologies can be extended for modelling of software systems and engineering systems e.g. PSL, STEPML, UML, SysML can be extended/adapted for use in particular problems.
Further Research
Further research is needed into modelling based on SWRL, to model conditional statements, and OWL-S Editor (Elenius et al., 2005) with UML style diagrams, together with investigation and use of online search facilities for services and process models. The reusable process architectures and process models held in an ontology, could also be translated as necessary between OWL-S and BPEL (Business Process Execution Language) representations. Also, Meta-Programming and Rule-based languages could be used to develop an interface to an end user programming environment. Models could be encoded and checked via languages such as MathLang (Kamareddine et el., 2005).
