The goal of this workshop is to explore cognitive issues in knowledge engineering processes and tools, and to examine where techniques from the field of information visualization might help with these issues. Knowledge engineering is often a complex area for end-user and engineer alike. We anticipate the workshop will be of interest to several groups:

• professionals interested in improving knowledge capture technology, particularly in the areas of tool adoption and usability;
• developers of information visualization solutions to knowledge engineering domains;
• people with interests in the area of cognitive support for complex tasks.

For example, a researcher who has created a knowledge sketching tool will be interested to discover how this tool may be combined with information visualization techniques in order to improve the usability and utility of the tool for the end-user.

Knowledge engineering is seeing more and more interest from communities outside AI, computer science, and logic, particularly due to emerging Semantic Web technologies. To better support the various processes involved in knowledge engineering, techniques from the field of information visualization can be very helpful. Information visualization techniques provide a means to make discoveries, make decisions, and provide explanations about data, in a way which leverages innate human spatial reasoning abilities. For example, humans can interpret information represented as complex pictures much more easily than they can lines of text. The workshop will be concerned with, but not necessarily limited to, the following topics:

Dr. Storey's main research interests involve understanding how people solve complex tasks, and designing technologies to facilitate navigating and understanding large information spaces. With her students, she is working on a variety of projects within the areas of software engineering, human-computer interaction, information visualization, social informatics and knowledge management. Dr. Storey is part of the program committee for Infovis 2003 and Softvis 2003, as well as general chair of VisSoft 2003. Dr. Geroimenko's main research interests concern knowledge representation and the Semantic Web; in particular, he is interested in how information visualization might aid in delivering and designing intelligent systems. Some other interests include visual interaction with semantic web ontologies and interactive multimedia interfaces for XML applications. He is the also the organizer for the Third International Symposium on Visualisation of the Semantic Web, at the IEEE International Conference on Information Visualisation - IV2003, in London, July 2003. Dr. Lethbridge is interested in knowledge-based reverse engineering, user interface design, and knowledge engineering, particularly user interfaces to allow the browsing of knowledge bases. He developed the CODE4 knowledge management system and is the pedagogy co-chair of IEEE/ACM Computing Curriculum / Software Engineering (CCSE), the international effort to standardize software engineering curricula.

We invite short discussion papers, limited to 4-6 pages, which describe ongoing work or new ideas within the scope of the workshop. Papers may also be in the form of a position statement, indicating a writer's particular opinion on a subject related to the workshop. Thought-provoking papers are always welcome!

Submission procedure: Please email submissions, in PDF format only, to
nernst(at)cs.uvic.ca (note: spam protected) by midnight Pacific Daylight Time July 30th 2003 (0700 July 31 UTC).

Submission format: Please use this Word template or the LaTex style sheet file (.sty) (an example .tex file). This template is based on the official ACM templates for proceedings. In concordance with requirements of the ACM digital library, please include categories and subject descriptors that best describe your submission. The hierarchy of descriptors can be found here (for example, some submissions may fall under the category "I.2.4: Knowledge Representation Formalisms and Methods".) You may include optional keywords. Note that reviewer assignments will be based on the contents of the abstract, as well as these descriptors and keywords. Accepted papers will be published as part of the KCAP 2003 workshops.
