Dear all,

All, sorry for being silent recently (been travelling, etc).

I suggest to write further replies to the mailinglist only from now on,
as I hope that everybody has subscribed in between. Let's continue the
discussion there

I will send a reply to Tom's vocab suggestion and andreas' trust
addition suggestion in the next few days (at the moment covered with a
large pile of reviews :-/) Thanks for all this input!

best,
axel

>>Dear all,
>>
>>sorry for the delay due to constant travelling, please find below a
>>summary of the discussion we had on the ExpertFinder-Lunch at ESWC (last
>>Tuesday, noon) in Innsbruck:
>>
>>Summary of ACTION ITEMS:
>>
>>ACTION: Tom Heath to circulate a *simple* draft vocabulary for
>>expressing expertise, experience, and a few other relations.
>>
>>ACTION: Soeren and the others from Leipzig promised to add to the Wiki
>>page an extensible list of sources/Webpages which we could think about
>>wrapping/annotating with this new vocabulary (ie citation indexes,
>>sourceforge database, FP7 experts list, etc.)
>>
>>ACTION: Alexander/Uldis promised to ... (shame on me, I cannot read my
>>notes here properly anymore, it had something to do with "tools" ;-) )
>>
>>ACTION: Axel to pick up/drive again the initial effort on creating
>>declarative mappings between overlapping vocabs
>>(http://www.rdfweb.org/topic/ExpertFinder_2fmappings)

>>
>>Here my notes:
>>
>>First, all told a bit on their background/interest in the topic.
>>
>>Tassilo mentioned their SemNetMan (http://www.semnetman.net/) project
>>which is very related.
>>
>>Andreas mentioned tagging, skills matching against DBPedia as an
>>interesting topic (http://dbpedia.org/docs/) Soeren supported this.
>>
>>Soeeren and Jens told about their LDAP binding to open RDF data.
>>(poster presented at ESWC).
>>
>>In a biref discussion of how/what can be done towards standardization,
>>the SWEO interest group was mentioned http://www.w3.org/2001/sw/sweo/
>>which overlaps in purpose partly with the goals of ExpertFinder.
>>
>>Harold/Adrian mentioned their ruleresponder system: responder.ruleml.org
>>- a Web agent for collaborative Team Organizations which is based on
>>RuleML, RuleML could also be interesting for vocab mappings.
>>
>>Asma mentioned her project on student group coordination (which she also
>>presented a poster on during ESWC's PhD Symposium)
>>
>>
>>We discussed the necessity for a simple vocab to annotate/describe
>>expertise as a simple extension of e.g. FOAF or SIOC.
>>
>>Tom volunteered to share an initial vocab he uses already along these
>>lines... this might be the most important outcome of this meeting, if we
>>manage to create and spread such a mini-vocabulary a bit!
>>
>>Some basic properties could be:
>>
>>interestedIn (domain foaf:Agent range ???:topic)
>>hasExpertiseIn (domain foaf:Agent range ???:topic)
>>providesExpertiseIn (domain foaf:Agent range ???:topic)
>>
>>the difference bertween these three being:
>>interest doesn't imply expertise, having expertise doesn't imply that
>>you want to share/sell/provide this expertise. (I am not sure about the
>>last one, still, since it seems then somehow missing *how* this
>>expertise is provided...)
>>
>>More interesting than just the simple properties might be *who* states
>>these properties, ie. it might be much more interesting if I say that
>>someone else is expert in XYZ than if I state that I have expertise
>>myself in XYZ.
>>
>>issues like SPAM/privacy/trustworthyness arise from just such a simple
>>set of properties, but maybe this is just a good reason to start with
>>something VERY small.
>>
>>We then discussed which sites might be a good starting point to
>>extract/wrap such expertise vocab from. citation indexes, sourceforge
>>database, FP7 experts list, LinkedIn, Xing, easychair were mentioned...
>>obvoulsy not all of them provide their data.
>>Soeren volunteered to set up an initial list of possible candidate
>>sources to wrap there and set up a page on the expertfinder wiki.
>>
>>I have two more action items that Alexandre and Uldis promised something
>>which I cannot read anymore, unfortunately ;-) (please complete this
>>missing part!), and that I promised to pick up the issue of publishing
>>vocab mappings again.
>>
>>
>>That was it, as far as I remember,
>>additions/follow-ups *very* welcome!
