  1. SRL: The Next Decade Lise Getoor University of Maryland, College Park ILP07 June 21, 2007

  2. Past: Focus on Representations LBN RBN SRM PRISM RDBN RPM CLP(BN) SLR BLOG PLL pRN PER SLP PRM MLN HMRF RMN RNM DAPER RDBN RDN BLP SGLR

  3. Present: Focus on Tasks • Collective Classification • Datasets and code available athttp://www.cs.umd.edu/linqs/projects/lbc • Information Diffusion • Entity Resolution • Datasets and code available at http://www.cs.umd.edu/linqs/projects/er • Link Prediction • Community Discovery/Group Detection • Ontology Alignment

  4. The Entity Resolution Problem James Smith John Smith “John Smith” “Jim Smith” “J Smith” “James Smith” “Jon Smith” Jonathan Smith “J Smith” “Jonthan Smith” Issues: • Identification • Disambiguation

  6. Present: Focus on Tasks • Collective Classification • Datasets and data generator available athttp://www.cs.umd.edu/linqs/projects/lbc • Information Diffusion • Entity Resolution • Datasets and code available at http://www.cs.umd.edu/linqs/projects/er • Link Prediction • Community Discovery/Group Detection • Ontology Alignment

  7. ILIADS • Goal: • Produce high-quality integration via a flexible method able to adapt to a wide variety of ontology sizes and structures • Method: • Combining statistical and logical inference • Use schema (structure) and data (instances) effectively • Solution: • Integrated Learning In Alignment of Data and Schema (ILIADS) • Datasets and code available at:http://www.cs.umd.edu/linqs/projects/iliads

  8. Future: Focus on Integrated Tasks • Putting it all together… • Bioinformatics • Computer Vision • Natural Language Processing • Personal Information Management

  9. Research Agenda • Visual Analytics • Complexity of the integrated SRL tasks require sophisticated user interfaces which allow user feedback and support explanation • Query-time adaptive information gathering • Complexity of the integrated SRL tasks require flexible, adaptive algorithms which retrieve relevant information in real time • Some related areas to keep in mind: resurgence of work in probabilistic databases (DB), social network analysis (social science), network science (physicists)

  10. D-Dupe: An Interactive Tool for Entity Resolution http://www.cs.umd.edu/projects/linqs/ddupe Novel combination of network visualization and statistical relational models well-suited to the visual analytic task at hand
