Experience

- Summer Intern in Web Search Group, Baidu Inc. (2011.07-2011.11)

• Responsible for building a cache framework for posting lists:   

• Analyze the characteristics of query term log in the real world web search engine.

• Implement an efficient static cache framework which takes advantage of the observed characteristics.

• Introduce a query term sampling mechanism which periodically provides feedback to the static cache module and helps the module to work efficiently.
