Tokratna tema bo iz podrocja Knowledge-Managementa,
ki je v zadnjih letih (spet) na pohodu in pridobiva kar precej
pozornosti tudi v komercialnih sferah. Gost iz Moskve
Dmitri Soshnikov, nam bo predstavil in demonstriral
svoj sistem za manipulacijo z bazami znanja.

JULIA - A Java-based toolkit for building distributed
knowledge-based systems for knowledge sharing
and re-use based on production-frame knowledge
The effective ways of sharing expert knowledge over computer networks are
important for many modern applications in intelligent information systems.
While some existing approaches are based on portable ontologies and their
use in multi-agent systems, we intend to show that classical frame knowledge
representation with production rules can be successfully used for collective
knowledge sharing and re-use. Frame hierarchy in such a system is
distributed over the network, and different types of inheritance are
introduced that allow transferring dynamic knowledge or applying it
remotely, and also modeling blackboard architecture. Frame knowledge
representation also allows for natural integration with relational databases
and object/component software models, giving alternative approach to active
and deductive databases for reasoning over relational data.
A toolkit called JULIA (Java Universal Library for Intelligent Applications)
has been developed that supports outlined approach. Due to some distinctive
features, it can also be successfully used in creating standalone and
embedded intelligent applications, including web-based systems. In the
presentation, some of the applications would be outlined, including
intelligent adaptive testing, tutoring systems, intelligent information
system for medical diagnosis and others.
