Project
(Selected)

Slot Filling with Scalable Machine Learning
May 2013 - Dec 2013

1. Applied the distant(weak) supervision learining methods to train the relation classifiers on terabyte size data set, in order to answer the questions like ”who did create Google” or ”what is Obama’s job title”, etc.
2. Built a efficient system which can retrieve a collection of entities from the target large text corpus to fill in values for predefined slots (relation attributes) for a given entity in a reference Knowledge Base (Knowledge Base Population).
3. Proposed an algorithm called Focus-Entity Slot Filling algorithm for Slot Filling task, which inputs a single ``focus entity'' ef and a set of relations R, then finds all other entities that the focus entity is related to via some relation in R from a large given unstructured natural language corpus.

"Who To Follow" Recommendation System
Dec 2012 - May 2013

1. Explored the "who to follow" recommendation problem in Twitter like social networks.
2. Incorporated the social network structure with user and item features to provide recommendation by using the personalized random walk.
3. Implemented distributed feature extraction and recommendation system with MapReduce framework and GraphChi (process very large graph computations on a single machine).
4. Tested system on KDDCUP12 Tencent Dataset, got rank 50th among about 700 teams.
