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 ("


The features and rationales of WebKB-2 and its MSO have been previously
(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):

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
A 4-level indented list of the upper part of the resulting taxonomy
can by accessed via
If the link encodings are a problem, add &longLinkNames at the end of
the URL or see

Filtering on a particular source can be done, e.g. enter sumo#* in the
Category Search interface:
(in the displayed taxonomies, dots replace categories not from the SUMO).
