Presentation Transcript

  1. Ralf Schenkel Making XML IR Systems Usable

  2. TopX: Bridging the DB&IR Gap Combining DBish… • top-k evaluation of NEXI/XPath FullText • specialized indexes with redundancy • sub-second answer time for real-life workloads … and IRish aspects • scoring function with some theoretic foundation • high-quality results (in benchmarks and real life) • reasonable user interface

  3. Towards XML IR for Real Users NEXI/XPath/XQuery: No languages for users Need for intelligent user interfaces for query formulation and refinement Interactive integration of user feedback (within zero time) • Sources for explicit and implicit feedback • Maintaining a user model • Proactive query expansion and evaluation

  4. New Trends, New Challenges • Multimodal Retrieval: Combine • textual data (text, XML) • multimedia data (images, video, music) • metadata (XML, RDF) • Distributed Retrieval: • XML-IR in P2P networks • XML-IR in Social networks
