A Methodology-Based Workbench for KBS Life-Cycle Support

Objective

VITAL's aim is to produce a KBS development methodology and a knowledge engineering workbench supporting it. The workbench extends the functionalities of Open KADS, a KADS-based knowledge modelling tool supplied by Bull Cediag.
A knowledge based system (KBS) development methodology and a knowledge engineering workbench supporting it have been developed. The workbench extends the functionalities of Open KADS, a KADS based knowledge modelling tool. To guarantee the usefulness of the results, the methodology and its workbench have been built from the requirements of a selection of large industrial projects in both civil and military industries. The workbench can be reused to build the future version of Open KADS, and it can also be directly exploited as a training environment to disseminate the KADS technology in industry.

The initial version of the methodology has been experimented with as part of pilot projects. The methodology and the workbench are currently being extended in various different ways, including: interfaces with software engineering and systems engineering methodologies and tools;
KADS editors are being complemented by a computer aided support of knowledge model building;
support of design and implementation of knowledge bases;
use as a federal modelling language for several kinds of artificial intelligence techniques (eg neural nets, machine learning).
To guarantee the usefulness of VITAL results, the methodology and its workbench are built from the requirements of a selection of large industrial projects in both civil and military industries. These projects include SACHEM for Sollac - building a KBS to support blast furnace process control, and HORIZON - building the planning and decision-making aids of a combat management system for Thomson-CSF/NCS.

Although the VITAL Workbench will be re-used to build the future version of Open KADS, it will also be directly exploited as a training environment to disseminate the KADS technology in the industry.

The initial version of the VITAL methodology has been experimented as part of pilot projects and in the context of the operational HORIZON project. The VITAL methodology and the VITAL Workbench are currently extended in various different ways, including:

- interfaces with software engineering and systems engineering methodologies and tools have been achieved or are under way (eg with ENTREPRISE II, RDD-100, FOUNDATION)
- KADS editors are complemented by a computer-aided support of knowledge model building based on the ACKNOWLEDGE GDM knowledge acquisition-driven modelling approach.
- KADS is extended to support the design and implementation of knowledge-bases.
- KADS is used as a federal modelling language for several kinds of artificial intelligence techniques (eg neural nets, machine learning).
