update on BioRDF (and Homepage)

<kei> http://esw.w3.org/topic/HCLSIG_BioRDF_Subgroup

kei: updated BioRDF homepage this weekend
... wrote introductory paragraph
... please make suggestions on wording
... listed objectives:
... .. enhance HCLS KB; new datasets to help KB span HC and LS
... .. identify scientic use cases
... .. maintainability of data sets
... .. disseminate the HCLS KB (and SemWeb) gospel

Jun: will we include the pointers to the new KBs query interfaces?

kei: good idea

Jun: relevent literature, e.g. special issues on life science data integration

kei: could go under meetings. if the list gets to long, could move to a separate page

<scribe> ACTION: kei to start a list of relevent literature on the BioRDF homepage [recorded in http://www.w3.org/2009/01/12-hcls-minutes.html#action01]

matthias_samwald: [update on HCLS KB at DERI]
... SPARQL endpoint up and running
... data consists only of neurocommons
... not finalized a DRUPAL interface
... looking at performance integrations, e.g. reconfiguring index to improve performance of queries which don't include named graphs

kei: do you plan to incorporate additional sources?

matthias_samwald: within BioSioc, yes. but need discussion within the BioRDF group to see what we want in there
... suggested we take a closer look at what is coming out of Virtuoso
... neurocommons KB will be offered in the Amazon cloud computing infrastructure
... can be used as a comodity by us

<AdrianP> http://www.corporate-semantic-web.de/hcls.html

AdrianP: we have an AllegroGraph triple store at Free Univ Berlin
... have loaded the Senselab data

kei: senselab ontology available in the neurcommons KB? so it's redundant?

AdrianP: yes

kei: we're not trying to compare the performance of these two triple stores
... but is good to make folks aware of the features available in the two

matthias_samwald: [update on SWAN SIOC]

<AdrianP> composition of multiple triple-stores into a single virtual store

RobFrost: triple store comparison helps you learn about and select proprietary features
... but certainly having non-overlapping content is the driving force
... [DBPedia and neuro-receptor use case]

kei: need to look at what component needs to be added to one of these interfaces
... can we identify a couple queries that are useful for comparison purposes, while we are thinking about the dataset to include

RobFrost: tying in another, non-HCLS database, including less-structured wiki content seems intriguing

<AdrianP> AllegroGraph supports RDFS++ Reasoning

<AdrianP> and integrates with RacerPro for DL reasoning

AdrianP: AllegroGraph has query support for RDFS++

kei: can is support this construction at arbitrary levels?

mscottm: two ways to reach the same result:
... .. e.g. go off-line with Pellet, run the transitive closures, and re-insert into the graph
... .. query-time reasoning is of course more convenient

<AdrianP> yes, we need to try it out

mscottm: there are some stores that are supposed to reason over a 200M triples
... many tasks don't scale to that level

<matthias_samwald> yes it has

<AdrianP> yes

<matthias_samwald> (meaning: virtuoso has features for subclass/suproperty reasoning)

introductions

query federation demo

update on HCLS KB

<RobFrost> I can test out the virtuoso subsumption support on the yago receptor tree in dbpedia

matthias_samwald: [update on BioSioc]
... email list and a rudimentary wiki page

<RobFrost> http://dbpedia.org/class/yago/Receptor105608868

matthias_samwald: will give a short presentation next week
... idea is to take an approach simpler than the HCLS KB
... take only the important statements
... plan to optimize for querying
... and develop UIs
... expect to use RDFa to embed SIOC statements
... want to explore the A tag for representing [structured] biological statements in [unstructured] pages
... thesis: can be useful given intuitive interfaces

<matthias_samwald> "aTag", a shorthand for "associative tag".

query federation demo

<matthias_samwald> I need to leave now, bye!

kei: we need to demo queries across heterogeneous DB
... first is the neuroscience data integration use case
... in the last charter, we showed how SemWeb could be used for integrating life science data
... want to re-use that data
... have drilled down a little bit in thinking about linking neurons cells and genes
... need to consider receptors
... can combine receptor trees from multiple sources
... once folks find a receptor of interest, users can drill down

http://www.w3.org/2004/10/04-pharmaFederate/

kei: it seems we have diverse approaches to federation
... how can we coordinate these?

mscottm: one prob is "what part of the federation system has what's interesting to me?"
... the common naming system makes this a bit easier
... i.e. i can register myself as supplying information about X

<RobFrost> http://dbpedia.org/page/5-HT3_receptor

<AdrianP> bye
