  1. WP2 Discovery mechanism of the OpenKnowledge system(“Semantic routing”)(presented by Ronny Siebes) OpenKnowledge project review WP2 -Discovery

  2. What we did last year on WP2: Functional description + architecture of the OK- System (D2.1a and D2.1b) [additional work as a decision to get an actual working prototype and final system] Emulation of routing mechanisms (D2.2?) 3. Implementation discovery service (prototype and beyond) OpenKnowledge project review WP2 -Discovery

  3. Functional description + architecture of the OK-system • What is the Open-Knowledge System? • Current limitations leading to a validation of our system. • What are our goals of the Open-Knowledge System? • Large scale in humans and machines • Diffentiation between types of participants, like average user, programmers … • Low integration effort with existing work • Open participation • Re-use, re-use and re-use • Means to evaluate who is good and who’s not • Why the Open-Knowledge system is a good idea? • Comparison with MAS, P2P, Grids, WWW, SW • How would the system look like? • User perspective (‘screenshots’ and functionality) • System overview in a technical sense (covered by D2.1b) OpenKnowledge project review WP2 -Discovery

  4. Functional description + architecture of the OK-system • Can we give examples where the system will be useful? • Emergency response • Bio- informatics • SW tool development • Which techniques will be applicable? • Interaction models • Mapping • Query relaxation • Discovery • Trust + reputation • Media2semantics • Semantic web tools • How will we evaluate the system? • (for each point of 6 we say how) OpenKnowledge project review WP2 -Discovery

  5. Emulation experiments • Compared JXTA, Pgrid and FreePastry • JXTA implementation has many bugs and algorithm does not scale • Pgrid takes lots of time to stabalize • FreePastry is easy and works • Compared different routing algorithms • Emulations of hundreds of nodes on the DAS2 OpenKnowledge project review WP2 -Discovery
