Developing a product configuration system is a non-trivial and challenging task for various reasons. First, the domain knowledge which has to be encoded into the system is often spread over several departments or functions within a company. Beside that, in many cases data from existing information systems have to be integrated into the configurator. Finally, the business rules or technical cons...

The value of a corporate information system such as an experience base tends to degrade with time. To keep the value of such a system, maintenance is an essential. Maintenance should not simply happen ad-hoc but systematically and based on specific maintenance knowledge. As a jump-start for maintenance, maintenance knowledge should be available right from the start of continuous operation. This...

Abstract: Knowledge Management is most necessary and valuable in a collaborative and distributed environment. A problem with commercial knowledge management tools is that they do not understand at a deep level the content that they are managing. In this paper we discuss the System for Collaborative Open Ontology Production (SCOOP), which manipulates logic expressions and checks for redundancies...

Knowledge representation has long had the insight that one data model, if it is expressive enough, is both necessary and sufficient for adequately storing information. Software engineering, alas, has gone a different way and uses an assortment of models. This model heterogeneity leads to problems of understanding and maintenance, because mappings between them are unavoidable and complicated. We...

Knowledge engineering suffers from a lack of formal tools for understanding domains of interest. Current practice relies on an intuitive, informal approach for collecting expert knowledge and formulating it into a representation scheme adequate for symbolic processing. Implicit in this process, the knowledge engineer formulates a model of the domain, and creates formal data structures (knowledg...

Abstract. In the paper the examples of software process simulations in an integrated IT environment are described. All examples come from an integrated IT environment in one of the biggest Polish firms in TELCO sector. Simulation models description is based on BPMN standard and ARIS Business Simulator was used as a tool to conduct experiments. These models describe the process of introducing a ...

This paper presents a general discussion of the role of formal methods in Knowledge Engineering. We give an historical account of the development of the eld of Knowledge Engineering towards the use of formal methods. Subsequently, we discuss the pro's and cons of formal methods. We do this by summarising the proclaimed advantages, and by arguing against some of the commonly heard objections aga...

This special issue is dedicated to the 2007 International Conference on Intelligent Systems and Knowledge Engineering (ISKE2007) held on October 15-16, 2007 in Chengdu, China. ISKE has become a major forum of contacts between research scientists, engineers and practitioners in the area of intelligent systems for knowledge engineering. ISKE2007 is the 2nd in a series of conferences on Intelligen...

This paper will describe the MikroKosmos methodology for the knowledge engineering of a computational lexicon used for text analysis. To do so, the paper outlines the general requirements for a knowledge base to be used for NLP, followed by specific requirements for building the lexical knowledge source. To highlight the issue of efficiency and reusability, the paper will contrast knowledge eng...
