Research Topics

We are interested in enabling technologies for intelligent retrieval and mining data/document/object retrieval systems.

We are pursuing research in the following directions.

  • Web Search [WSDM2015,SIGIR2014]
  • Knowledge/Language Understanding [AAAI2015,EACL2014,ACL2014,AAAI2014,ACL2013,WWW2013,ICDE2013]
  • Text/Data Mining [ICDM2015,ACL2014,ACL2013,ICDE2013]
