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.

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.
