[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!
