- 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
