6. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 6 Scenario No clue…

7. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 7 Peer Portal We want a community Portal!!!!

8. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 8 User-specific requirements Send complex queries to the portal and knowledge base Which authors are most often mentioned regarding a specific topic? The top five/ most relevant papers regarding a topic? The most relevant conferences regarding a topic? Who is engaged in a specific topic (pot. Community) ? Adjoining communities? (Semi-)automatic extraction of an implicitly given community profile Bibster is knowledge base Definition of a “rough” user profile Automatic Community detection with Invitation => Portal Generation => Peer2Peer meets Semantic Web Technology!!!

9. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 9 Analysis What do We have? Easy Available local Bibster SWRC entries local papers KAON Portal Available CiteSeer Citetation Index Conferences

10. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 10 Approach Community-Portal How can the community-buildup be supported with semantic web technologies? Extraction of information from locally stored papers + Chat + extraction of information from web sites (Text-To-Onto?) + publication lists/ team or staff descriptions Semantic portal showing bibliographic information + links to papers/ persons/ projects, Usage logging-> Extraction of rules Automatic genefration of additional information using pre- defined rules

11. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 11 WebUser (Peer) Our Architecture Community-Portal (KAON) Bibster Chat Web Sites staff descriptions publication lists Ontologie „Virtual Community“ Invitation to join a potential community Refinement SWRC-Ontologie Instances

12. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 12 Objective for One Day Wrap one Peer behind a KAON portal User friendly complex querying of the P2P Network via the portal Extract link between locally stored.pdfs and locally stored Bibtex Rank the most relevant Persons based on the stored Papers Rank the most relevant Papers based on the stored Papers

13. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 13 Problems Data integration –KAON labels –SWRC ontology in DAML –Properties in SWRC are not in RDFS –Virtual Integration in one day? –RDFS export of BIBSTER needs major adaptation Solution e.g. grep " \n \n \n \n\n"}'grep " \n \n \n \n\n"}'

14. The Semantic Web In One Day © AIFB, FZI, ontoprise, 2004 14 Achievements of One Day Wrap one Peer behind a KAON portal User friendly complex querying of the P2P Network via the portal Extract link between locally stored.pdfs and locally stored Bibtex Rank the most relevant Persons based on the stored Papers Rank the most relevant Papers based on the stored Papers With files possible NO time Done NO time
