Acknowledgments

Portions of this chapter were conceived or written while both authors worked for VerticalNet, Inc., and also while one of the authors was at The MITRE Corporation. We acknowledge the support of both companies and express our appreciation for that support. We also thank Nicola Guarino for permission to display his classification of knowledge representation levels (Table 7-1) from his 1994 paper presented at the IV Wittgenstein Symposium. Finally, we thank the anonymous reviewers of this chapter for their comments and suggestions.
