-> http://lists.w3.org/Archives/Member/member-xg-rdb2rdf/2008Apr/att-0003/04-rdb2rdf-minutes.html Last Weeks Minutes

Wolfgang: micheal proposed to have f2f is iswc in October

speaker: the date might be too late

Ashok: willing to host before or after the conference

wolfgang: could be arranged

Ashok: I might have difficulty before but should be okay doing it afterwards

scribe: could you get back that to us on this?

Ahmed: how about STC '07 in May in San Jose

Ashok: we could possibly do both

scribe: dates are May 18 - 22nd

DavidOrchard: will not be available, but that shouldn't hold up that as an option

Ahmed: will investigate if we can host and confirm the dates

Ashok: we now have a wiki

<Ashok> Wiki: http://esw.w3.org/topic/Rdb2RdfXG

<ssahoo2> URL for the presentation: http://esw.w3.org/topic/Rdb2RdfXG?action=AttachFile&do=view&target=RDB2RDF-Knoesis.pps

Ashok: there was a request to do a state of the art or literature survey

scribe: this is what we are supposed to be doing

[ agreement that we should do this ]

Ashok: we need volunteers

ssahoo2: i'll volunteer

Wolfgang: i'll volunteer as well

DavidOrchard: will this go on the wiki?

Ashok: yes

<ssahoo2> URL for the presentation: http://esw.w3.org/topic/Rdb2RdfXG?action=AttachFile&do=view&target=RDB2RDF-Knoesis.pps

ssahoo2: in biomedical domain. large dataset (entrez genes)

scribe: two approaches (one without an ontology and another without)

Ashok: was OWL used as well?

ssahoo2: in the first case, OWL was not used

scribe: on Entrez gene screens, implicit relationships are shown

Ashok: where did you specify what you were looking for

ssahoo2: each gene corresponds to a record in the DB

ssahoo2: we are trying to model the relationships explicitely in RDF

scribe: we started with the XML representation of the source data
... a very large XML file
... starting from the XML representation made the mapping effort much easier than via SQL calls against the original database

ssahoo2: the data was from 2 database and we were able to use named entities to make the links

DavidOrchard: were these new relationship or previously known?

ssahoo2: in method 2, the instances extracted conform to a created OWL-DL model for the data source

scribe: it spanned information model and domain concepts

Ashok: how were the connections made (via what analysis)?

ssahoo2: the diagram demonstrates the result of a query (SPARQL)

scribe: then some post-processing was done to derive the diagram

ssahoo2: this was an application-driven approach

Ashok: you were able to get pretty good performance from the queries dispatched on the dataset?

ssahoo2: yes

ssahoo2: in the first method, inference was used

scribe: in the second case inferencing was not used

Jenni: what is the next step?

ssahoo2: we have started work on integrating uniprot data

scribe: requires extending the ECOM schema

Jenni: what is the current usage pattern

ssahoo2: we gave the result back to the biological researchers

scribe: after confirmation we will make this available for their queries, however they are not familiar with SPARQL

ssahoo2: creating the XSLT was a recursive process (10 days initially)

speaker: did the dataset change much and was subsequent work needed to hange the XSLT?

ssahoo2: not much work was needed beyond the original formulation of the XSLT

<Ashok> Question was from Orri Erling

Orri: I would like to reserve a slot to speak 2 weeks hence
