Annotation. The book captures the latest developments in the areas of knowledge engineering and software engineering. Particular emphasis is placed upon applying knowledge-based methods to software engineering problems. The Conference, from which the papers are coming, originated in order to provide a forum in which the latest developments in the field of knowledge-based software engineering could be discussed. Although initially targeting scientists from Japan, the CIS countries and countries in Central and Eastern Europe, the authors come from many countries throughout the world. JCKBSE 2002 continues with this tradition and is anticipating even wider international participation. Furthermore, the scope of the conference as indicated by its topics has been updated to reflect the recent development in all the three covered areas, i.e. knowledge engineering, software engineering, and knowledge based software engineering.
