4What is HCLS?
- The Semantic Web Health Care and Life Sciences
Interest Group is chartered to develop and
support the use of Semantic Web technologies and
practices to improve collaboration, research and
development, and innovation adoption in the
health care and life science domains. Success in
these domains will ultimately depend on a
foundation of semantically rich systems,
processes and information interoperability. - The scope of HCLSIG includes
- Core vocabularies and ontologies to support
cross-community data integration and
collaborative efforts - Guidelines and Best Practices for Resource
Identification to support integrity and version
control - Better integration of Scientific Publication with
people, data, software, publications, and
clinical trials
5HCLS Themes
- Principle activities have centered around
- Building a broad and strong community
- Exploring and documenting Use Cases
- Converting resources to RDF-OWL
- Learning to work with semantic web
query/inference technology such as SPARQL, OWL,
and rule engines.
6Organization
- Chairs Eric Neumann, Tonya Hongsermeier
- Group divided in to task forces (coordinator)
- BioRDF. Established initially to convert
biomedical data to RDF (Susie Stephens) - BIONT. Established initially to be resource for
ontology needs for other groups (Vipul Kashyap) - DSE (Drug Safety and Efficacy). Established
initially to work on SW technology to support
monitoring drug safety, pharmacovigilance (Eric
Neumann) - ACPP (Adaptable Clinical Protocols and Pathways)
Established initially to work on method of
representing and computing applicability of
protocols to dynamically changing patient status
(Helen Chen) - COI (Clinical Observations Interoperability).
Established recently with two goals 1) Establish
new collaboration with health care industry
players 2) Work on issues at the intersection of
electronic medical records and health care
organization needs. (Vipul Kashyap)

15Data Aggregation
- Think Smart Mash-up
- Data aggregated for any application ins
semantically consistent way.
16Semantic Web Basics
17The Current Web
Resources
- What the computer sees Dumb links
- No semantics - lta hrefgt treated just like ltboldgt
- Minimal machine-processable information

18The Semantic Web

- RDF- Resource Description Framework
- Machine-processable semantic information
- Semantic context published making the data more
informative to both humans and machines

22Connecting graphs
- Integrate graphs from multiple resources
- Query across resources
23Recombinant Data
- Graphs can be filtered and pivoted, without
losing meaning
24Where does Semantic Web Fit In?
Connecting Legacy Data to SWD2R, MagLev
25Semantic Web Applied to Disease Mechanism and
Pharmacology
26Drug Safety and Efficacy
- Group focuses on
- Draft an approach for clinical trial data that is
in line with the Clinical Data Interchange
Standards(CDISC) Study Data Tabulation Model
(SDTM) - Can SW standards help with EDC?
- Work on aggregating patient data with
pharmacogenomic information. - Use Case around Pharmacovigilance
- Emphasis on display/visualization of clinical
trial data, rather than query - They have a demo that uses the Simile projects
Exhibit tools to display information merging
three points of view - Demographics
- Treatments
- Adverse Events
- SNP
27Clinical Observations Interoperability
- Recently formed http//esw.w3.org/topic/HCLS/Ontol
ogyTaskForce/BIONTDSEDCM - Focusing on problem of identifying clinical trial
candidates based on constraints of participation
and information in medical records. - Clinical trial recruitment is an everybody-wins
situation - Patients want new cures and development of them
is dependent on trials - Pharma want new drugs to bring huge profits
- Running clinical trials is profitable for CROs
- Doctors and hospitals get money for identifying,
treating, and recording information about
patients. - Technical problems (evaluation of constraints)
are very similar to those identified and somewhat
addressed in ACPP. Driver of rule and OWL
technology. - Has brought in new industry and academic
participants. - DSE, ACPP, and BioONT participants are joining
this effort.
28BioRDF Demo Neurocommons Triple Store
- Challenge Go beyond toy size examples of
Semantic Web - Strategy 1) Work on translating a dozen existing
databases using OBO methodology and OWL, focused
on neuroscience research questions - Pubmed/Mesh mappings
- OBO ontologies, including Gene functions,
molecular processes, cellular components - Neuroscience ontologies Senselab, BAMS, Allen
Brain Atlas - Strategy 2) Develop capability to run
interesting SPARQL queries at scale - 300 Million triples
- Open source, reproducible
- Queries that could only be done previously with a
lot of effort - Demonstrate Practice a useful prelude to
developing Best Practice - Enthusiastic response from community. We often
hear - This is the first time Ive seen semantic web
technology do anything useful - WWW2007 Thank you from the semantic web
- Some problems solved, many remain, ongoing work.
29Adaptable Clinical Protocols and Pathways
- This group was active mostly in the first year
- Worked on Guideline Reference Ontology
- Prototyped three instances of guidelines based on
the ontology - Worked on reasoning with inclusion/exclusion
criteria - Developed clear use cases that need temporal
concepts reasoning - Two rule engines used. Helen Chen Euler,
Chimezie Ogbuji Fuxi (his own work!) - This work is great arena for exploring the
difference between using OWL versus rules - Although research is finished, need more manpower
to write up results - AGFA benefited significantly from the work and it
has influenced their internal models. - SW is a strong focus in AGFA health care for
evidence based patient care, and they expect to
invest in it for years to come. - Helen, Chimezie are now bringing their
experiences to the new Clinical Observations
Interoperability group.
30URI recommendations project
- Jonathan Rees leading work in BioRDF on upcoming
note - Problem is stable identifiers for knowledge
resources of import, and for entities in the
world - Proteins, Organs, Symptoms etc.
- Motivated by complaints about inadequate
instruction - From providers not knowing good practices for
minting URIs - From users not knowing how to name or make
statements about resources that can be
effectively integrated - Community finds current AWWW and TAG
documentation and recommendations inadequate - Problem is not easily separable from issues of
providing good practices for making use of the
URIs, such as having mechanisms for figuring out
what they mean
31New charter process
- Goal is to design one or two charters for working
group and/or interest group. - Initial step was drafting of questionnaire
circulated to wide swath of life sciences and
health care community. We listed possible
activities and asked which would be of interest
for participation. Currently almost 50 responses - http//www.w3.org/2007/06/HCLSForm
- Next step analyze and draft a charter that is
responsive to the feedback gained from the
questionnaire. Target is for new charter to
circulate early November.
32Looking Forward
- Work with TAG over architectural needs for
Semantic Web for science. Important to get time
with them at Tech Plenary meeting in November. - Find and recruit more members like AGFA, who feel
they got value from group participation. Current
membership has no shortage of other organizations
with some tie to health care/life sciences,
either as vendors (e.g. IBM) or primary, such as
pharma (Merck, Pfizer) - Targeting pharma, health care, vendors, not
currently SW-ready standards groups (e.g. CDISC),
FDA, NIH sponsored projects, and academic
research leaders. - Further recruitment should be based on listening
to needs, addressing them with focused projects
within the next HCLS. Focus on increasing
credibility. - Acceptance of SW technologys role in pharma/
health care is growing, hopefully to soon match
enthusiasm from life sciences community. They are
looking for guidance, and we need to provide it.
