Objectives and Approach

The purpose of the KIWIS project is to design and develop the KIWIS industrial prototype of a knowledge-base system to support sophisticated applications requiring complex operations on data and knowledge, possibly located in other systems.

KIWIS will provide an integrated knowledge-representation language and programming environment for user modification, and establish an open environment with extensible, friendly graphical interfaces to distributed databases and knowledge bases. The KIWIS system will connect to external, traditional database systems, and give a complex-object view of their data. It will also establish a cooperating network environment consisting of distributed knowledge-based systems, by enabling an intelligent dialogue with other KIWIS systems.

The KIWIS system architecture will support a persistent knowledge representation language, LOCO, based on object-oriented and logic programming paradigms, that will be tightly integrated. The architecture will be composed of a number of layers that incrementally add power to the system, thus providing both low-level facilities (eg, for the storage and manipulation of persistent complex objects in central and in secondary memory), and sophisticated operators to implement every feature of the language.

KIWIS draws on the results of the earlier KIWI project (number 1117).

The workpackages are concerned with the specification, design, implementation, and testing of the following components:

Exploitation

The industrial partners (Alcatel, CRAI, Enidata and Origin) envisage the exploitation of the project's results for the provision of high-quality information systems.

The LOCO language is in use at several sites and has found favourable acceptance from these users.
