Creating Knowledge out of Interlinked Data

• Explore and demonstrate the application of linked data principles for procuring

contracts in the public sector

• Enhance the market process of meeting supply and demand by avoiding the need

for manual integration, via leveraging the distributed linked data infrastructure

• Explore the possibilities for cross-fertilization between the LOD scenarios in public

sector and electronic commerce

• …

• Task 9a.2: Matching the demand of public sector bodies with linked commerce dataChallenges:

• Scalability of matchmaking algorithms

• Designing the gold standard

• Optimizing matchmaking quality metrics

• Proving competitive advantage over traditional (RDB) approach

• …

• Task 9a.3: Analytics of linked data for public sector contractsChallenges:

• Enhancing analytical (and) reporting tools so as to cope with richly structured RDF data

• …

Creating Knowledge out of Interlinked Data

• Initial version of Public Contracts ontology; still needs:• More complete alignment with TED structure

• Better documentation

• Review by a larger group

• Contacts to public contract announcement sources• Convince companies implementing relevant web portals to produce RDF (discussions under way)

• Both tenders and contracts

• Library of scraping and cleaning tools• Coverage must be increased

• Adherence to LOD2 Stack will be sought

• Samples of already triplified data• Also EU (TED) and other countries (Gerrmany – via WKD?)

• Publish; wiki. Similar to benchmarking…

• Provisional LD infrastructure• Migration from Sesame to Virtuoso envisaged

• The supplier side yet (nearly) unexplored…• Registry of business entities could be linked to published contracts

Task 9a.1: „Creating linked data for PS contracts“ starting points
