15:18:00 [chimezie]
Ashok: there was a request to do a state of the art or literature survey
15:18:12 [chimezie]
... this is what we are supposed to be doing
15:18:36 [chimezie]
[ agreement that we should do this ]
15:18:54 [chimezie]

15:25:04 [chimezie]
ssahoo2: in biomedical domain. large dataset (entrez genes)
15:25:43 [chimezie]
... two approaches (one without an ontology and another without)
15:26:58 [chimezie]
Ashok: was OWL used as well?
15:27:13 [chimezie]
ssahoo2: in the first case, OWL was not used
15:28:32 [chimezie]
... on Entrez gene screens, implicit relationships are shown
15:29:04 [chimezie]
Ashok: where did you specify what you were looking for
15:29:22 [chimezie]
ssahoo2: each gene corresponds to a record in the DB
15:30:35 [chimezie]
ssahoo2: we are trying to model the relationships explicitely in RDF
15:30:50 [chimezie]
... we started with the XML representation of the source data
15:32:19 [chimezie]
... a very large XML file
15:33:16 [chimezie]
... starting from the XML representation made the mapping effort much easier than via SQL calls against the original database
15:34:52 [chimezie]
ssahoo2: the data was from 2 database and we were able to use named entities to make the links
15:35:11 [chimezie]
DavidOrchard: were these new relationship or previously known?
15:39:57 [chimezie]
ssahoo2: in method 2, the instances extracted conform to a created OWL-DL model for the data source
15:40:22 [chimezie]
... it spanned information model and domain concepts
15:40:54 [chimezie]
Ashok: how were the connections made (via what analysis)?
15:41:08 [chimezie]
ssahoo2: the diagram demonstrates the result of a query (SPARQL)
15:41:27 [chimezie]
... then some post-processing was done to derive the diagram
15:43:23 [chimezie]
ssahoo2: this was an application-driven approach
15:44:49 [chimezie]
Ashok: you were able to get pretty good performance from the queries dispatched on the dataset?
15:45:35 [chimezie]
ssahoo2: yes
15:46:03 [chimezie]
ssahoo2: in the first method, inference was used
15:46:14 [chimezie]
... in the second case inferencing was not used
15:46:30 [chimezie]
Jenni: what is the next step?
15:46:41 [chimezie]
ssahoo2: we have started work on integrating uniprot data
15:46:54 [chimezie]
... requires extending the ECOM schema
15:47:18 [chimezie]
Jenni: what is the current usage pattern
15:47:29 [chimezie]
ssahoo2: we gave the result back to the biological researchers
15:47:44 [chimezie]
... after confirmation we will make this available for their queries, however they are not familiar with SPARQL
15:48:21 [chimezie]
ssahoo2: creating the XSLT was a recursive process (10 days initially)
15:50:14 [chimezie]
speaker: did the dataset change much and was subsequent work needed to hange the XSLT?
15:50:49 [chimezie]
ssahoo2: not much work was needed beyond the original formulation of the XSLT
15:51:35 [Ashok]
Question was from Orri Erling
15:52:09 [chimezie]
Orri: I would like to reserve a slot to speak 2 weeks hence
