2 Southhampton, 1/03 2 www.mindswap.org Adding power via Semantic Web Tools can be domain independent Your tool should be usable in lots of contexts! Use the standards: OWL and its successors crucial Tools should assume multiple ontologies Its the links, stupid Ontology search, collection, integration crucial Check out the DAML crawler (http://www.daml.org/crawler) BackEnd technologies must be scaleable Can co-evolve with Semantic Web size But remember, the Web is HUGE
3 Southhampton, 1/03 3 www.mindswap.org Semantic Web Knowledge Acquisition Virtually no one will create ontologies from scratch High-End ontology developers will be a tiny percentage (10,000 High end Web Designers = 1/10,000 of users) It is easier to read then to create ontologies Expect cut and paste (HTML analogy) Most used OWL editor to date is Emacs Can Bootstrap from existing content HTML screen scrapers, structured data, Excel spread sheets,… No training allowed Motivated users will skim the docs on occasion Most users want to use it now Everyone has a browser - deploy tools through that Common metaphors must be used: Form fill, menu, search Note : No formal justification for any of these - but it worked before!
4 Southhampton, 1/03 4 www.mindswap.org GIVE IT AWAY!!!!! There is, and will be, no market for any of this unless we create it! No one will make money selling their tools until we have MANY more users Make small, cheap, easy to download version of your tools available Give it away The big winners on the web made it available for free: Browsers: Mosaic, Netscape, IE Plug-ins: Flash, RealPlayer, Quicktime Tools: Adobe, Real Media
5 Southhampton, 1/03 5 www.mindswap.org RIC: Allow extensibility Users MUST be able to add their own concepts Semantic Web (and OWL) allow this Advanced users will become ontology providers It will be cool to have yours be the ontology of choice in a domain Consistency CANNOT be maintained on the web May be a useful heuristic Insist on consistency and the Semantic Web fails!

8 Southhampton, 1/03 8 www.mindswap.org Web travel agents Query processed: 73 answers found Google document search finds 235,312 possible page hits. Http://www…/CowTexas.html claims the answer is 289,921,836 A database entitled Texas Cattle Association can be queried for the answer, but you will need authorization as a state employee. A computer program that can compute that number is offered by the State of Texas Cattlemans Cooperative, click here to run program.... The sex network can answer anything that troubles you, click here for relief... The UFO network claims the all cows in Texas have been replaced by aliens How many cows are there in Texas?
