<scribe> Meeting: prov-xg
<scribe> Scribe: Simon Miles
<scribe> ScribeNick: smiles
<lkagal> Great Ivan ! In March, I won't even need a fridge to keep it cold ;)
<ivan> :-)
Yolanda: main topic today, review curated use cases and plan for applying to rest of use cases
<Paolo> http://www.w3.org/2005/Incubator/prov/wiki/Talk:Use_Case_Template
Paolo: been writing up discussion
on template on Wiki discussion page, will send link when
written up
... Points of curation (1) Provenance is means to end, so use
case should describe without ref to provenance
... provenance is then referred to as solution in Problems and
Limitations section
... (2) use case should be general, represent set of instances
in different domains (e.g. timeliness does not just apply to
traffic data)
... also should not be tied to technology, e.g. removed
LinkedData from timeliness scenario, put as solution in
Problems and Limitations
... (3) should highlight technical challenges of each use case,
categorise challenge as about management, use, content
... (talking about
http://www.w3.org/2005/Incubator/prov/wiki/Use_Case_Linked_Data_Timeliness)
... (4) separate content, management, usage information
... dicsussion on modifying template, Satya made suggestions to
mailing list to remove repititions
... conclusion of discussion: Current Practice is part of
Background, but Goal is separate summary from Use Case
Scenario
... please put discussions on use case, template pages; Paolo,
Satya, Simon will respond
Yolanda: 4 guidlines came from group (last telecon)
Paolo: also added Provenance Dimensions section to template, to specify Primary dimension and some Secondary dimensions
Yolanda: use cases general (not just for one domain): add narrative about technology, e.g. this case applies to LinkedData but would also apply to eScience (refer to other areas not in original case)
<pgroth> +q
Paolo: domain gives reason why
use case is there, what inspiration
... can generalise, be clear not intrinsic to domain
Yolanda: where to put this in template?
<pgroth> unanticipated uses? -> other uses?
Paolo: suggests Background, best
not to add more sections
... please make use of references (links to Mendeley biblio) in
Existing Work section
Paul: already seeing repitition
in use case types (e.g. collections)
... could use Unanticipated Uses section for other
applications
Yolanda: but in this case is anticipated, and matches existing general use case
<YolandaG> sorry my phone got disconnected, i'll call right back
Paolo: no use case used all
sections, Unanticipated Uses not yet used
... was ambiguous whether Goal was user goal or use of
provenance
... we are trying to be clear that Goal is user goal then how
technology applies
<Paolo> http://www.w3.org/2005/Incubator/prov/wiki/Talk:Use_Case_Template
Yolanda: see, add discussion at
link above (but not complete yet)
... new use cases added, more intended but not added yet
<Deborah> +1 for me for intending to add use cases but did not get to it.
Yolanda: set deadline of end of year to have all use cases following curation guidelines
<Paolo> yes
<jmccuske> I've added two use cases but haven't linked to them yet.
Yolanda: owners improve their own use cases, curation team then check
<jmccuske> search in the wiki for "Jim McCusker"/
Yolanda: use cases ready for checking Dec 31, curation team look at for telecon on Jan 8
<pgroth> +q
Paul: is deadline for submission of use cases, or for also complete curation?
Yolanda: deadline (Dec 31) is for submission and self-curation
<Paolo> ok, deadline is fine if we are talking about self-curation
<crunnega> +q
<ssahoo2> I agree with Yolanda
Yolanda: when you believe you
have completed your use case, send to one of the three
curators
... in Jan, need to move on to how to technically solve use
cases
<ssahoo2> I think thats a good plan Paolo
me too
Paolo: instead, send complete use case to all 3 curators, so one available can take it up
Yolanda: please declare if you
are intending to add a use case
... I want to add a case where attribution of info is important
(someone said it, a journal recorded it...)
... I want to add a case where adding axiom to document, what
sources were consulted
... I want to add a case on the provenance of a decision,
decide sources, why whichever trusted
<Paolo> all these use cases are extremely important IMO
Deborah: I will add a case on
text analytics: text extractors generate sentences, from wide
variety of sources
... I may add a case on improving decision processes in
producing end conclusions
<Deborah> yolanda will send me a pointer from biology for my text analytics use case. my prior work will cite some intelligence community work
Irini: working on implicit information in RDF, provenance of SPARQL query
Yolanda: if existing use case applicable to you, contact owner to apply your technology to it
<lkagal> +1 for private data use case
Luc: added two use cases: use of private data, prov of decision making (drafts, now to be self-curated)
Paulo: ideas on human level provenance, will connect to Yolanda's use case
<jmccuske> +1 for private data use case, including de-identifying/anonymizing portions of a provenance graph.
<Paolo> not me...
<Deborah> i may join the provenance of decision making as well
Paolo: will go over use cases added a while ago to self-curate
<crunnega> microphone issues
<YolandaG> Christine: you can make any comments on IRC directly, sorry about the microphone
James C: had workshop in April on provenance use cases, will try to write up some, particularly evidence in public policy, engineering/design
<crunnega> Thank you. I would like to review and add to current use cases and then see if I can identify any missing use cases mindful of the deadline.
<Deborah> yes - I am happy to collaborate on that.
Yolanda: discussed with Deborah about why KB/reasoner would produce a given answer, could discuss with James to abstract issues (also maybe relevant to Irini)
Jim Mc: added two use cases on closures from multiple prov graphs, relation between two experiment graphs to determine whether one reproducing other: need to be looked over
Yolanda: mark use case as Draft
even if not finished, for others to see
... second case above may be same as Simon's Result Differences
case, possibly merge
<lkagal> Sorry, can't unmute am in a noisy environment.
Olaf: not planning to add any new use cases, but will adjust existing
Paul: added two cultural heritage cases, will add Creative Commons case and one on scientific publishing
Yolanda: have been in contact with CC people, so send to her
<lkagal> I'd like to contribute to the private data use case (maybe generalize to any data) and the linked data use cases.
Simon: will look at where dimensions not covered, then conttribute cases if appropriate
Yolanda: will also check dimensions at end of month, discuss on mailing list
Satya: not intending to add more use cases
Yolanda: asks Satya to write up or ask originators to write up use case on prov of scientific hypotheses from
<Aleksey> I would like to contribute to the data quality-aware cases (Information Quality Assessment for Linked Data)
Andreas: intend case on licensing, copyrighting, contracting
Paulo: working on combining proofs, may come up with inconsistent graphs because of different justifications of axioms: please contact him if interested in conflicts in graphs, will coordinate writing case with Deborah
Yolanda: will send suggested F2F
meeting dates to list
... telecon next week, but not next two coz holidays
Irini: will scribe next meeting
<ssahoo2> quit
trackbot, end telcon
