Hi, I worked, as a Ph.D. student, with Prof. Hinrich Schütze at Ludwig Maximilian University of Munich, Germany in 2013-2017. Before, I got MSc degree from Peking University, China in 2013 and BSc degree from Northwestern Polytechnical University, China in 2010.  In late Oct. 2017, I will join the group of Prof. Dan Roth in UPenn as a postdoc.

Research topic, deep learning in NLP, spans:
  • Representation Learning: Embedding language units and  graph data such as Freebase, WordNet etc.;
  • Relation Learning: textual entailment, paraphrase identification, answer selection, query-doc;
  • Question-Answeringmachine comprehension,  factoid QA against knowledge graphs.

In addition, some basic  machine learning issues also meet my taste: online learning, domain adaptation, zero/low-shot learning...

Released Resources:
1) FLORS: the state-of-the-art online POS tagger in domain adaptation scenario. It performs online representation learning (i.e., domain adaptation is performed by incrementally adapting word representations to the new domain). (EMNLP'2015)

2) Phrase embeddings: the first version in the world. It contains continuous linguistic phrases like "eye disease'' as well as discontinuous phrases like "turn...on'' etc. (ICLR'2013, ACL'2014)

3) Word Meta-Embeddings: A version of word embeddings which were derived by combining several pre-trained word embedding versions, such as word2vec, GloVe, C&W etc.  (ACL'2016)
