Friday, November 8, 2002 - Issue 9 _____ New Stories: DAML PI Meeting held
in Portland, OR The DAML Principal Investigators meeting was held October
16 - 18 in Portland, OR. Significant progress was reported in the areas
of language, tools and application development. Additionally, the DARPA
DAML Program Manager, Murray Burke, provided his vision for focusing the
research effo= rts during 2003. The PI meeting agenda and links to the
presentations is at: http://www.daml.org/meetings/2002/10/pi/ W3C releases
Web Ontology Language (OWL) Guide Version 1.0 Abstract: The World Wide
Web as it is currently constituted resembles a poorly mapped geography.
Our insight into the documents and capabilities available are based on
keyword searches, abetted by clever use of documen= t connectivity and
usage patterns. The sheer mass of this data is unmanagea= ble without powerful
tool support. In order to map this terrain more precisel= y, computational
agents require machine-readable descriptions of the content and capabilities
of web accessible resources. These descriptions must be = in addition to
the human-readable versions of that information. The Web Ontology Language
(OWL) is intended to provide a language that ca= n be used to describe
the classes and relations between them that are inher= ent in Web documents
and applications. This document demonstrates the use of = the OWL language
to formalize a domain by defining classes and properties of those classes,
define individuals and assert properties about them, and reason about these
classes and individuals to the degree permitted by the formal semantics
of the OWL language. The sections are organized to prese= nt an incremental
definition of a set of classes, properties and individuals= , beginning
with the fundamentals and proceeding to more complex language components.
http://www.w3.org/TR/2002/WD-owl-guide-20021104/ W3C releases OWL test
cases The W3C Web Ontolgoy Working Group has published a set of test cases
for = "" Web Ontology Language (OWL). Many of the test cases illustrate
the correc= t usage of the Web Ontology Language (OWL), and the formal
meaning of its constructs. Other test cases illustrate the resolution of
issues consider= ed by the working group. http://www.w3.org/TR/2002/WD-owl-test-20021024/#introduction
DAML Query Language released The Joint US/EU ad hoc Agent Markup Language
Committee has announced the initial release of the DAML Query Language
(DQL). DQL provides a language and protocol for agent-to-agent query-answering
dialogues using knowledge represented in DAML+OIL, potentially involving
inference and remote knowledge bases. The current release consists of an
abstract specificatio= n. Continuing work is expected to result in a normative
external syntax and = a fully defined specification of answer justifications.
http://www.daml.org/2002/08/dql/ DAML Rules An increased emphasis on rules
emerged at the DAML PI Meeting and a decis= ion was made to more closely
align the DAML Rules effort with the Rule Markup Language (RuleML) initiative.
Information summarizing ongoing work on DAML Rules (DAML-R) is now availa=
ble at http://www.daml.org/rules/. DAML+OIL Time Ontology released A collaborative
project, led by Jerry Hobbs, aims to develop a representative ontology
of time that expresses temporal concepts and properties common to any formalization
of time. For more information on t= his project see: http://www.cs.rochester.edu/~ferguson/daml/.
As a part of th= is effort, the DAML+OIL time ontology is now available
at: http://www.ai.sri.com/daml/ontologies/time/Time.daml DAML Article to
appear in IEEE Distributed Systems Online An article, =93DAML+OIL, an Ontology
Language for the Semantic Web=94, by= Jim Hendler, Deborah McGuinness,
Richard Fikes and Lynn Stein, is scheduled f= or publication on the IEEE
Distributed Systems Online web site sometime in November: http://dsonline.computer.org/
DAML-S Version 0.7 released Version 0.7 of DAML-S (DARPA Agent Markup Language
for Services) is available at http://www.daml.org/services/. DAML-S is
a DAML+OIL-based We= b service ontology, which supplies Web service providers
with a core set of markup language constructs for describing the properties
and capabilities= of their Web services in unambiguous, computer-intepretable
form. DAML-S als= o provides service requesters with semantic constructs
to describe the functionality and constraints of services desired by a
requester. Version 0.7 introduces the Grounding ontology, and also includes
substantial refinements to the Profile and Process Model ontologies. In
addition, a n= ew example of a Profile-based (yellow-pages style) service
taxonomy is presented, and the existing service examples have been made
more complete. The new Grounding ontology ties DAML-S in with the Web Services
Descripti= on Language (WSDL), an emerging, collaborative industry effort
that is currently the focus of a W3C working group. As noted on the release
home page, feedback is welcome from all interested parties, through the
www-ws@xxxxxx email list. AFRL=92s Commander-To-Database Query Mediator
using DAML The Air Force Research Laboratory (AFRL) has developed a prototype
application to apply military facility ontologies to answer high-level
queries in support of Effects Based Operations. The =93DAML Commander-To-Database
Query Mediator=94 prototype demonstrates how expressed in
DAML can be used to bridge an understanding gap between quer= ies represented
in two different, but related, domains and applications. The tool allows
non intelligence analysts to access low-level military intelligence databases
without having to know the low-level SQL search terminology. A web-based
user interface was developed to allow users to formulate pseudo-natural
language queries concerning the status of variou= s military facility types
in foreign nations. The high-level military facility classifications and
ontology was developed based on a standardiz= ed classification of facilities
enforced by the DIA (Defense Intelligence Agency). Likewise, the low-level
intelligence data ontology was derived f= rom a subset of the modernized
integrated database (MIDB) schema. The actual mediation between these two
ontologies was handled by placing DAML restrictions on various properties
and classes from one ontology to the other. Moreover, the application itself,
which handled the query mediatio= n, processing, and results delivery,
was developed with Java servlet technol= ogy and made use of the Jena API
for DAML. This prototype development exercis= ed the DAML lifecycle and
demonstrates a potential military application of DAML. Several collaboration
areas were identified at the recent DAML Principal Investigator meeting
in Portland, OR, including integration wit= h the SONAT experiment.=94
DAML at conferences Planning is underway for the 2nd International Semantic
Web Conference (ISWC2003) to be held 20-23 October 2003 in Sanibel Island,
Florida, with= a strong representation from the DAML program. Upcoming
deadlines include Workshop Proposals on December 16 and Papers on April
15. See http://iswc2003.semanticweb.org for
