Scenarios and applications e-Government: ministerial units alignment 11/14 Semantic technologies  Interoperability  Using STs  Experiences Issues e-Gov scenario of UK and US software agents trying to align ministerial units from 4 ministries/departments: UKFCO, UKHO, USDoJ, USDoS use taxonomy and ministry/dept. structure but also responsibility and how these are allocated within the ministry/dept. Use IF technology to represent the structure and infer dependencies in the lattice: Use initial partial alignment of UK to US responsibilities (tokens) and IF classifications and IF-Map mechanism to infer the type level alignment:

Scenarios and applications Bioinformatics: terminology alignment 12/14 Bioinformatics alignment scenario Part of the annual ontology alignment contest (sponsored by OAEI) FMA  Foundational Model of Anatomy large reference .owl ontology ~31MB, 73k classes, ~100 relations OpenGALEN  open source version of a healthcare ontology anatomy part, (compact .owl ontology, ~4MB, ~25 classes, ~30 relations) ,[object Object],[object Object],[object Object],Semantic technologies  Interoperability  Using STs  Experiences Issues
