UMBC, JHU, and MIT are working together
on a set of issues under funding from DARPA |
|
UMBC (Finin, et. al.) is focused on
integrating communicating agents, DAML and the Web |
|
JHU APL (Mayfield, et. al.) is building
information indexing and retrieval systems that work with documents and
queries that contain a mixture of free text, XML and DAML |
|
MIT Sloan School (Grosof et. al.) is
developing techniques for integrating rule based technology and distributed
belief into DAML |
|
To be integrated in agent-based
applications involving search and using rule-based reasoning. |
|
|
|
|
We’ve defined and use the following
ontologies, all at http://daml.umbc.edu/ontologies/ |
|
calendar-ont.daml – calendar and
schedule info |
|
classification.daml – ACM CCS topics |
|
person-ont.daml – people and their
attributes |
|
place-ont.daml – talk locations |
|
profile-ont.daml – user modeling info |
|
talk-ont.daml – talks info |
|
topic-ont.daml – topics and interests |
|
|
|
Generation from DB to DAML and HTML
mediated by MySQL, Java servlets, and
JSP. |
|
Generation of DAML descriptions and
user profiles from HTML forms. |
|
Creation & use of DAML-encoded user
models describing interests and ontology extensions. |
|
Ontologies for events, people,
places, schedules, topics, etc. |
|
Automatic HTML form (pre) filling from
DAML. |
|
Syncing of talks with Palm calendars
via Coola. |
|
Automatic classification of talks into
topic ontology |
|
A XSB-based DAML/RDF reasoning engine. |
|
|
|
|
Much multi-agent systems work is
grounded in Agent Communication Languages (e.g., KQML, FIPA) and associated software infrastructure such as the DARPA
Grid |
|
The paradigm has been peer-to-peer
message oriented communication mediated by brokers and facilitators. |
|
The DAML program invites different
paradigms which will require some changes in ACLs and their associates
software systems. |
|
Agents “publish” beliefs, requests, and
other “speech acts” on web pages. |
|
Agents “discover” what peers have
published on the web. |
|
The software agent research community
is very interested in the semantic web and DAML |
|
|
|
|
|
Where does SW markup come from? |
|
From Databases, just like much of the
HTML on today’s web |
|
But, where does the DB content come
from? |
|
From legacy systems |
|
From web forms or custom HCIs |
|
From focused search engines feeding
into web scrapers or information extraction apps |
|
Are the DAML tools there? |
|
Some in beta form |
|
Many XML and RDF tools are very handy |
|
We used protégé and XMLSpy to create
and edit ontologies |
|
|
|

|
ITTALKS is a useful, fairly
sophisticated web application |
|
The semantic web concepts and DAML in
particular |
|
Make it easier to develop and maintain
ITTALKS |
|
