PROJECTS
LTP is a software package that provides a Chinese natural language processing pipeline along with web service API.
  • one of the developers and the major maintainer of LTP.
  • developed 4 modules including Chinese word segmentation, POSTagging, NER and Dependency parsing in a perceptron algorithm framework.
  • developed the RESTful API and contributed to the development of website.

Zpar Project, 2013.10 - present
ZPar is statistical multi-language parser. ZPar provides integrated systems that perform word segmentation, part-of-speech tagging, dependency parsing or phrase structure parsing.
  • developed transition based non-projective dependency parser.
  • developed bug fixes.
