[Following a SWADE meeting with Alistair Miles, CCLRC, Dave Beckett, ILRT] Can I kick this off (re the requirements spec & implementation of a thesaurus service)? Obviously feel free to disagree/refine any of what I state here. It's a bit off the cuff. I think our scope includes : a) A thesaurus service accessible to the end-user via a browser b) A "3rd party" thesaurus service, available for M2M networking The set of "questions" that might be asked of either type of service seem to be the same for both & to include: [* asking for information pertaining to a single thesaurus *] - "give me the preferred term for some concept X in some thesaurus Y" - "give me the non-preferred term(s) for some concept X in some thesaurus Y" - "give me the scope note for some concept X in some thesaurus Y" - "give me the broader/narrower/related term for some term Z in some thesaurus Y" [nb use & use for] [ - perhaps some further questions based around the idea of asking for the *type* of relations between hierarchical terms within a thesaurus for example 'broader-generic', 'broader-partitive' (part-of) as in your document, Alistair? Or are we keeping that sort of data "behind the scenes"?] - "give me metadata about thesaurus Y (s.a. it's language, it's creator ???)" [* asking for information re mappings between thesauri *] - "give me the equivalent term(s) for X in some target thesaurus/thesauri (if it exists), or partial equivalent if it exists" [& scope here - if we hope for a proof-of-concept scenario where some human & semi-automated effort has gone into "preparing" hierarchical KOS's that employ different types of subsumption rules - for precise questions about mapped thesauri, using properties s.a. "overlapsWith", "disjointWith" etc as mentioned in your document, Alistair?] - also, need to provide query support re AND/OR etc re post-coordination, or is this out of scope? USE CASES for a) Jim Hendler's use case (from rdf-ig I think) - marking up web resources using a thesaurus service SOSIG's use case - marking up resources for a specific user community - social sciences in this case Alistair Mile's use case - tool support for better searching and also browsing using web search engines s.a. Google [similar scenario applies e.g. to SOSIG end user] USE CASES for b) Cross-search (re ("invisible") better query recall across a set of data repositories, e.g. this would extend a tool like SPP's xsearch) Cross-browse (so end-user can "seamlessly" browse a hierarchy of categories represented across many data repositories in order to refine their search terms, say. ie 2 or more KOS's have been "federated") Apologies in advance for any ambiguous terminology!
