KEG seminar

  6. DSL 2 • Fabian M. Suchanek (Telecom ParisTech University) • A Hitchhiker's guide to Ontology  •  Ontology; YAGO  •  YAGO 2 + time and space information • Alignment of knowledge bases • Rule mining (semantic correlations) • Provenance of ontological data KEG seminar

  7. DSL 3 • Dr. Nan Tang (Qatar Computing Research Institute, Doha, Qatar) • Big Data Cleaning • Different aspects of data cleaning • Error detection • Data repairing KEG seminar

  8. DSL 4 • Dr. Xiaokui Xiao (Nanyang Technological University, Singapore) • Private Data Release via Wavelets and Bayesian Networks •  The privacy of the individual data • Privelet, utilizes wavelet transforms (any range-count query) • PrivBayes, employs Bayesian networks KEG seminar

  9. Tutorial • Xin Luna Dong (Google) • From Data Fusion to Knowledge Fusion  • The Sonya project • Knowledge Extraction • use 15 extractors to periodically extract knowledge from 1B+ Webpages. • only about 30% of the extracted triples are correct. KEG seminar

  10. Tutorial • Adapt data fusion techniques to solve the knowledge fusion  • leveraging the collective wisdom from different extractors and from different Web sources • compute well-calibrated probabilities for the truthfulness of each triple KEG seminar
