1. 10/4/20141 WP2 Discovery mechanism of the OpenKnowledge system (“Semantic routing”) (presented by Ronny Siebes) OpenKnowledge project review WP2 -Discovery

2. 10/4/20142 1.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] 2.Emulation of routing mechanisms (D2.2?) 3. Implementation discovery service (prototype and beyond) What we did last year on WP2: OpenKnowledge project review WP2 -Discovery

3. 10/4/20143 1.What is the Open-Knowledge System? 1.Current limitations leading to a validation of our system. 2.What are our goals of the Open-Knowledge System? 1.Large scale in humans and machines 2.Diffentiation between types of participants, like average user, programmers … 3.Low integration effort with existing work 4.Open participation 5.Re-use, re-use and re-use 6.Means to evaluate who is good and who’s not 3.Why the Open-Knowledge system is a good idea? 1.Comparison with MAS, P2P, Grids, WWW, SW 4.How would the system look like? 1.User perspective (‘screenshots’ and functionality) 2.System overview in a technical sense (covered by D2.1b) Functional description + architecture of the OK-system OpenKnowledge project review WP2 -Discovery

4. 10/4/20144 5.Can we give examples where the system will be useful? 1.Emergency response 2.Bio- informatics 3.SW tool development 6.Which techniques will be applicable? 1.Interaction models 2.Mapping 3.Query relaxation 4.Discovery 5.Trust + reputation 6.Media2semantics 7.Semantic web tools 7.How will we evaluate the system? (for each point of 6 we say how) Functional description + architecture of the OK-system OpenKnowledge project review WP2 -Discovery

5. 10/4/20145 -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 Emulation experiments OpenKnowledge project review WP2 -Discovery
