Nowadays, it is difficult and inefficient to publish, retrieve, compare, evaluate and learn ideas and techniques about knowledge engineering since they are not organized into a semantic network but stored within informal documents and hence scattered and described in various ways across millions of such documents (research articles, documentations, emails, etc.). Our knowledge server WebKB-2 supports the collaborative building of a formal or semiformal semantic network. We have begun creating such a network to permit a scalable sharing of information about knowledge engineering. This article illustrates and discusses this work.
