The Information Retrieval Group of CCIP Laboratory at University of Chinese Academy of Sciences conducts cutting-edge research in the areas of information retrieval, social media analysis and natural language processing. We are particularly interested in the following research fields:

  • Statistical modeling and machine learning for large-scale information retrieval
  • Social media search and mining
  • Automted essay scoring


On-going Research Projects

  • Automated Essay Scoring Based on Deep Neural Networks. Funded by National Natural Science Foundation of China (NSFC). 2015.1 - 2018.12
  • Modeling Bigrams for Large-scale Retrieval Applications. Funded by Beijing Natural Science Foundation (BJNSF). 2014.1 - 2017.9
  • Transduction-based Real-time Social Search. Funded by the Scientific Research Foundation for the Returned Overseas Chinese Scholars, State Education Ministry (SRF for ROCS, SEM). 2014.1 - 2016.9

Past Research Projects

  • Time-domain Simulation Analysis of Load Characteristic in Smart Grid. Industry Research Project. 2013.9 - 2015.8
  • The President's Fund of UCAS. Category A. 2011.5 - 2013.12
  • The President's Fund of UCAS. Category B. 2012.5 - 2014.4
  • Parameter-free Probabilistic Models for Information Retrieval. Funded by National Natural Science Foundation of China (NSFC). 2012.1 - 2014.12
