LANL ontology

The Los Alamos National Labs? strong ontology or LANL ontology is thought by some to be focused on imperial goals. It is a military-industrial ontology and a direct competitor to the living ontology.

A key focus is on the use of Semantic Networks for Homeland Security?" (Joslyn, Larkey, Mniszewski, Verspoor): "Knowledge extraction from text, text canonicalization, ontology research, and machine learning algorithms on large semantic networks" to find terrorist?s and put them on a no-fly list? or something silly like that.


Getting a decent link-type semantics? and an ontology for PCP has been
an important goal for a while. Like most everything we proposed over ten years ago, the community is moving quickly in our direction. In
particular, the need for ontology markup and exchange standard?s,
coupled with ((loosely hierarchical representations of semantic
relations)), is understood now more than ever. Cliff Joslyn?'s
Distributed Knowledge Systems and Modelling Team in Los Alamos is starting
to pursue this kind of activity
(external link). The goal is to develop a generic
knowledge environment which will allow communities to self-elicit? and
represent their ontological knowledge structures.

Some of this has been prompted by some very recent advances in
computational linguistics?. In particular, we're tracking the work
begun by Steven Pinker?, and much more fully developed now within the
linguistics community, towards the identification of a small,
canonical, generative set of semantic relations? related to each other
in a loosely hierarchical multiple inheritance type lattice. While
these are proposed to represent the semantics of natural language?
texts, we've hypothesized that they should also inform a sufficient
set of link types for ontological network?s.

Among the other things we're examining are Sowa's conceptual graph?s
and Visual Basic extensions to use Visio as a GUI platform. The other
essential ingredient is a sufficient, presumably XML-based, ontology
exchange markup language for full read-write compatibility. We're
tracking the standards community moving in this direction (e.g. The
WWW Consortium, DOM, XSchema, RDF, etc.).

Cliff was recently invited to SRI International? in Menlo Park, CA, to
address a loose consortium of Silicon Valley? researchers and
developers trying to develop a Dynamic Knowledge Repository (DKR)
within an Open Hypertext Standard (OHS). This group is led by ((Doug
Engelbart)) of SRI fame, and whose early work (invention of the mouse
and other essential elements of the present computer interface) we
know as being so important for us and everyone, and who is now with
the Bootstrap Institute? http://www.bootstrap.org(external link) along with SRI.

Cliff found Engelbart to be a charming and insightful man, who is
very appreciative of everything PCP is trying to do.

Cliff's talk spanned a number of issues, including PCP (technology
and form and content,), Lab activities, and the ideas described
above. You can look at the overheads http://www.c3.lanl.gov/~joslyn/KS_Team/sri.pdf(external link)
