Artificial immune systems represent key functions and properties of the biological immune system for solving problems in computational science. Specific approaches exist for modelling biological and artificial immune systems. This paper is focused on the usage of the OWL language in the artificial immune system modelling with the aid of the Protégé-OWL plugin.

This paper presents the results of the interoperability experiment proposed in EON2003, using the following ontology tools: Protégé-2000 and WebODE. We will show which knowledge is preserved and which knowledge is lost in the import/export processes between tools when using RDF(S) as an intermediate language.

Once the conceptual overview, in terms of a somewhat informal class diagram, has been designed in the course of engineering an ontology, the process of adding many of the appropriate logical axioms is mostly a routine task. We provide a Protégé plugin which supports this task, together with a visual user interface, based on established methods for ontology design pattern modeling.

We propose to demonstrate the process of capturing and logging ontology changes and use these logged changes for ontology recovery and visualization. Change Tracer, a Protégé plug-in we have developed for ontology recovery from one state to another (including roll-back and roll-forward) and visualization of ontology changes are structured as RDF graph. Users can also navigate through the histor...

The Lexical Grid (LexGrid) enables the integration of terminologies and ontologies through a common model, services, and tools. The LexGrid Editor is a prototype terminology authoring and maintenance tool designed for this environment. This demonstration will present an overview of the Editor’s functional capabilities in relation to technologies offered by the LexGrid platform. We will also dem...

The development of entrepreneurial skills within the education system increases the possibility of producing more entrepreneurs in future. Many economists now believe that entrepreneurship plays an important role in economic growth of a country. Entrepreneurial education can be used as a mediation tool for impacting attitude of people towards entrepreneurship. A Mentor plays an important role i...

There are many domain-specific and language-specific NLG systems, which are possibly adaptable across related domains and languages. The languages in the Bantu language family have their own set of features distinct from other major groups, which therefore severely limits the options to bootstrap an NLG system from existing ones. We present here our first proof-of-concept application for knowle...

We introduce the OWLlink API that implements the OWLlink protocol on top of the Java-based OWL API. Besides providing an API to access remote OWLlink reasoning engines, it turns any OWL API aware reasoner into an OWLlink server. As such the OWLlink API provides the missing piece to replace the outdated DIG protocol by OWLlink in applications such as Protégé.

During the past decade a number of modelling frameworks for knowledge based systems have been developed. In this paper an approach to the comparison of modelling frameworks is proposed, based on the aims and purposes behind the frameworks. A purpose oriented comparison of the frameworks DESIRE, CommonKADS, PROTÉGÉ-II, MIKE, VITAL and KARL provides insight in their differences and similarities.
