Michael V. Yudelson (C) Work Done in Hannover. Implement PService in P-R framework –Adapt external content (WebEx) Schedule-Based Annotation, Progress-Based Annotation –Communicate with PServices in ADAPT 2 Design PServices on ADAPT 2 side Technological component –Sesame RDF database –Jena RDF API –P-R framework

Michael V. Yudelson (C) Work Done in Hannover… Not! Prerequisites - describe data in RDF –LOs, Users/Groups, Topics*, Topics Schedule, LO-Schedule indexing, User Progress Demo –ADAPT 2 Directory, WebEx, Sesame *Previously done by Sergey

Michael V. Yudelson (C) Work Done in Hannover (cont’d) PServices Implemented –Schedule-Topic-Based adaptation QuizGUIDE-like annotation –Progress-Based adaptation Relies on CUMULATE –User-Group resolution helper service Bridge user base of P-R and ADAPT 2

Michael V. Yudelson (C) PServices in ADAPT 2 Value-Added Services –QuizGuide, QuizGuideSQL, NavEx –Limited to a closed corpus PServices –Provide adaptation for open corpus resources –Interpret results of such adaptation (visualize)

Michael V. Yudelson (C) PServices in ADAPT 2 (cont’d) First order objects –PService - adaptation agent has one or mode –Configuration(s) - instance of data PService can be run against RDF Stores, URI lists, Raw RDF PService run by invoking it with certain configuration –Prototype Demo

Michael V. Yudelson (C) Conclusions Stay in Hannover –Inspired work on ADAPT 2 PServices ADAPT2 PServices –Are in great need (esp. in DB course project) –Already work! –More need to be developed
