About
Currently I am a first-year graduate student at Language Technologies Institute, Carnegie Mellon University. My research interest lies in Information Retrieval, Natural Language Processing and Machine Learning. Supervised by Professor Jamie Callan and Chenyan Xiong, I am working on Entity Retreival in the Web of Data using Knowledge Graphs. Before coming to CMU, I received my Bachelor's degree (CS) from Nanjing University, where I focused on Natural Language Processing and Text Mining. |

Research
2015/09 - Present Graduate Research Assistant LTI, CMU |
Entity Ranking based on Knowledge Bases Advisor: Professor Jamie Callan We propose to improve entity retrieval performance with Learning to Ranking (LeToR) framework, where we mainly focus on SVM rank and ListMLE learning algorithms. We are currently focusing on a short paper for this work. |
2013/09 - 2015/06 Undergraduate Research Assistant NLP Lab, NJU |
Question Classification with Multiple Kernel Learning Advisor: Associate Professor Xinyu Dai We studied and implemented different tree kernels to integrate syntactic features of question text, which were then incorporated as basis-kernels in MKL algorithms to build multi-kernel classifiers. Experiemnts indicated that our multi-kernel classifier outperformed most single-kernel classifiers. SinaMicroblog-based Chinese Social Media Mining We developed a fast crawler to retrieve posts in personal social network using open API, and analyzed social data with NLP and machine learning algorithms. A D3.js-based platform was built to visualize the analysis results. |
2012/05 - 2013/05 Undergraudate WebSoft Group, NJU |
Ontology Based Recommender System Advisor: Professor Yuzhong Qu We developed an item-based collaborative recommendation system based on semantic ontologies. |
