SUO, The following draft ballot question is posted for review and comment. Please don't vote yet. Jim Schoening ================================================ Ballot Question: "Should the IEEE P1600.1 Standard Upper Ontology Working Group commence work on the Multi-Source Ontology (MSO) of the WebKB-2 knowledge server (www.webkb.org)." Background: The features and rationales of WebKB-2 and its MSO have been previously introduced: http://www.webkb.org/doc/onSUOlist/m031202Schoening.html (plus subsequent messages stored in the same directory). In short, each object - a category (type or individual), a link between categories, or a more complex statement (graph) - has an associated source (user and/or document), and a Web user can 1) query, re-use and add new categories, links or graphs, 2) remove those she have created (and mainly only those), 3) "correct other graphs" (represent alternative beliefs) by using relations such as pm#corrective_specialization. Knowledge additions being centralized and incremental, the objects can be highly interconnected (hence, retrievable and re-usable) and each detected inconsistency or redundancy is solved by its author, thus guiding her to write more precise and (re-)usable knowledge. However, the users can (and are advised to) store and document their knowledge within Web files and ask WebKB-2 to parse these files (until no error is detected and the knowledge is commited in the KB). The MSO of WebKB-2 is currently mainly composed of an extension and correction of the noun-related part of WordNet 1.7 plus some top-level ontologies (mainly, extensions of those of John Sowa in his books of 1984 and 2000, DOLCE, OWL and various categories from other sources): details are accessible from http://www.webkb.org/doc/papers/iccs03/ The integration of the SUMO is in progress. The 4D ontology named "Lifecycle integration Schema" is (and will remain) loosely integrated. This ontology, some general statements, and a few small domain ontologies are listed as example files in http://www.webkb.org/kb/ A 4-level indented list of the upper part of the resulting taxonomy can by accessed via http://www.webkb.org/bin/categSearch.cgi?categ=pm%23thing&recursLink=%3E&depth=3&hyperlinks If the link encodings are a problem, add &longLinkNames at the end of the URL or see http://www.webkb.org/doc/onSUOlist/m031216phmartin.html An indented list of the relation types can be accessed via http://www.webkb.org/bin/categSearch.cgi?categ=pm%23relation&recursLink=%3E&hyperlinks Filtering on a particular source can be done, e.g. enter sumo#* in the Category Search interface: http://www.webkb.org/interface/categSearch.html (in the displayed taxonomies, dots replace categories not from the SUMO).
