Description: This set of tool is intended to ease: 1) the building and the documentation of knowledge bases using the CG formalism, 2) the use of CGs for indexing or connecting elements of WWW-accessible documents (e.g. sentences, images, sections or whole documents), 3) the retrieval of these CGs or the elements they index, and 4) the cooperative construction of knowledge bases by multiple users (this feature is in construction).

Example domain paragraphs

      Retrieve, compare and vote for ideas, NOT documents or people. WebKB refers to the knowledge base (KB) servers WebKB-1 and WebKB-2. KB servers are not Web search engines ... [ More ] Please enable Javascript (see the Preferences options of your browser) since this tool requires it.

To search and add to the public KB of this WebKB-2 server, you can use: - The frame-based interface (two resizable frames: one for the menus and one for the results). - The following "simple category search" or pop-up menus for additional features. They are proposed after each list of results if you do not change that "default formatting option". For a category search, enter an English noun for an object you are interested in, for example "flight" or "person". You may use the wildcards '?' (for 0 or 1 unkno

If you need more document element indexation features or more script features than those provided by WebKB-2, and wish to store your knowledge within Web files only (that is, if you are ok with the fact that the knowledge in those files will not also be in a large public knowledge base and hence will be difficult to retrieve and compare or relate with knowledge from other users), use this WebKB-1 server . Hopefully in the future all the features of WebKB-1 will be integrated into WebKB-2.
