2. Ivan Herman, Applications of the Semantic Web ( 2 ) ‏ ( 2 )‏ > Semantic Web ≠ academic research only! SW has indeed a strong foundation in research results But the situation has evolved today

3. Ivan Herman, Applications of the Semantic Web ( 3 ) ‏ ( 3 )‏ > Remember the Web evolution? SW has indeed a strong foundation in research results But remember: (1) the Web was born at CERN… (2) …was first picked up by high energy physicists… (3) …then by academia at large… (4) …then by small businesses and start-ups… (5) “big business” came only later!  network effect kicked in early… Semantic Web is now at #4, and moving to #5!

4. Ivan Herman, Applications of the Semantic Web ( 4 ) ‏ ( 4 )‏ > May start with small communities The needs of a deployment application area:  have serious problem or opportunity  have the intellectual interest to pick up new things  have motivation to fix the problem  its data connects to other application areas  have an influence as a showcase for others The high energy physics community played this role for the Web in the 90’s

5. Ivan Herman, Applications of the Semantic Web ( 5 ) ‏ ( 5 )‏ > Some deployment communities The technology is picked up by specialized communities  just like the high energy physics community did for the original Web… Some examples: digital libraries, defense, eGovernment, energy sector, financial services, health care, oil and gas industry, life sciences … Health care and life science sector is now very active  also at W3C, in the form of an Interest Group

6. Ivan Herman, Applications of the Semantic Web ( 6 ) ‏ ( 6 )‏ > Emerging technologies hype cycle (2006)

7. Ivan Herman, Applications of the Semantic Web ( 7 ) ‏ ( 7 )‏ > The “corporate” landscape is moving Major companies offer (or will offer) Semantic Web tools or systems using Semantic Web: Adobe, Oracle, IBM, HP, Software AG, webMethods, Northrop Gruman, Altova, … Some of the names of active participants in W3C SW related groups: ILOG, HP, Agfa, SRI International, Fair Isaac Corp., Oracle, Boeing, IBM, Chevron, Siemens, Nokia, Merck, Pfizer, AstraZeneca, Sun, …

8. Ivan Herman, Applications of the Semantic Web ( 8 ) ‏ ( 8 )‏ > Applications are not always very complex… Eg: simple semantic annotations of patients’ data greatly enhances communications among doctors What is needed: some simple ontologies, an RDFa/microformat type editing environment Simple but powerful!

9. Ivan Herman, Applications of the Semantic Web ( 9 ) ‏ ( 9 )‏ > Data integration Data integration comes to the fore as one of the SW Application areas Very important for large application areas (life sciences, energy sector, eGovernment, financial institutions), as well as everyday applications (eg, reconciliation of calendar data) Life sciences example:  data in different labs…  data aimed at scientists, managers, clinical trial participants…  large scale public ontologies (genes, proteins, antibodies, …)  different formats (databases, spreadsheets, XML data, XHTML pages)  etc

11. Ivan Herman, Applications of the Semantic Web ( 11 ) ‏ ( 11 )‏ > General approach 1.Map the various data onto RDF assign URI-s to your data that may require a community-based approach, eg, how do I uniquely name a gene? “mapping” may mean on-the-fly SPARQL to SQL conversion, “scraping”, etc 2.Merge the resulting RDF graphs (with a possible help of ontologies, rules, etc, to combine the terms) 3.Start making queries on the whole!

12. Ivan Herman, Applications of the Semantic Web ( 12 ) ‏ ( 12 )‏ > Example: antibodies demo Scenario: find the known antibodies for a protein in a specific species Combine (“scrape”…) three different data sources  “Entrez protein sequence” from National Center for Biotechnology Information; conversion to RDF  “Antibody Directory” from Alzheimer Research Forum; scraping RDF from HTML  “Taxonomy information” from Wikispecies; use XSLT to extract RDF from XHTML Use SPARQL as an integration tool

Ivan Herman, Applications of the Semantic Web ( 14 ) ‏ ( 14 )‏ > A number of projects in the area Pfizer, NASA, Eli Lilly, MITRE Corp., Elsevier, EU Projects like Sculpteur and Artiste, UN FAO’s MeteoBroker, DartGrid, … Developments are under way at various places in the area Courtesy of Huajun Chen, Zhejiang University
