Peer-to-Peer Information Retrieval
Short description of the destination of this part of the EPOS project:
Precise satisfaction of information needs in interacting knowledge workspaces
- Improve user satisfaction by collaborative information retrieval
- exploit query experience resulting from previous queries together with user feedback on the query results
- associate query experience with the appropriate context and model elements
- re-use query experience to improve new user queries in a way that the results will better fit to the current context and the assumed user intentions
- Tap personal knowledge workspaces as an organizational memory resource
- communicate information needs across workspaces
- integrate answers from different workspaces to satisfy the query
Reuse query experience in order to improve search in collaborative workspaces
- Relevance feedback allows to save positive examples of query results as reusable experience
- Learn about successful query-result-concepts based on term occurrence
- Retrieved information objects are associated with the personal information models and the retrieval context. This association is transferred to the corresponding query experiences
- Current information needs are better satisfied by using stored query experiences for query reformulation
- The exchange of stored query experiences between individual workspaces helps to identify and build thematic communities
- other users in similar situations profit from previous experience
- particular queries are routed to appropriate partner workspaces to retrieve information across workspace boundaries
Research Topics:
- Peer-To-Peer IR (P2P-IR)
- How to identify the peers to inform/query ?
- How to merge search results from several peers?
- Quality estimation
- How relevant are the results from other peers?
- What makes a peer a specialist/expert/layman/amateur?
