Lee, It seems the DAML Services should also be a key element of a DAML Finder lifecycle. Also, shouldn't regular XML markup be an important piece of the overall picture? If the ultimate purpose of a DAML Finder is to find information for people it would need to take advantage of DAML markup content and XML markup content. Even if everything was marked up, the universe of marked up information would still likely be a mix of DAML+Oil and plain XML. I think one of the key uses of DAML ontologies and their instances may be to provide a rich context for conducting searches for data that is actually marked up in XML. Can you say some more about the idea of obtaining Search Parameters? What are some examples of Search Parameters and where would you get them from?

Lee Sent: Tuesday, July 31, 2001 12:19 PM To: 'daml-apps@daml.org' Cc: Jim Hendler (E-mail); David Martin-McCormick (E-mail) Subject: DAML Finder - Candidate Killer App To continue the discussions from the PI meeting, regarding "killer apps" for the semantic web and DAML+OIL, I'd like to propose another concept. "DAML Finder" is an application involving using SW technology to FIND people, places, and things on the web. The attached diagram provides an IDEF0 view (inputs, outputs, control, and mechanisms) of the lifecycle of DAML Finder use. 1) Ontology developers would develop ontologies for particular domains using ontology development tools 2) People who wanted their stuff to be found would use markup tools and the previously developed ontologies 3) Various folks would build user interfaces to query "searchers" for what they're looking for use those interfaces to obtain search parameters 4) Query software would use "hint lists" and crawling techniques to find desired information using inferencing on ontology specifications and searches through instance data 5) Various folks would build user interfaces to present the results of the search To explain the concept, a concrete example should be developed and demonstrated. For example, show how a company like restaurant.com could provide a service to help folks find restaurants near particular locations. The demo is NOT the objective, just a tool to help people understand the killer app of finding people, places, and things. Thoughts? Lee Lacy Dynamics Research Corporation <<Lifecycle.ppt>>
