We aim to enable synergetic collaboration between people and between people and computers to enlighten them and enrich their lives.
To achieve our mission, we develop scalable automatic content analysis methods and quality metrics to analyze a huge amount of online text such as blogs, community-based question answering, forum discussions, news, reviews, Twitter, Wikipedia, etc. and to harvest explicit and implicit knowledge from these media. To ensure the quality of harvested knowledge, we automatically construct per-topic global and local expert rankings through statistical analysis of the people who created the online contents. The results are not only used to rate harvested knowledge but also to form an active expert network to which users can connect. To leverage the collective intelligence of the crowd, we design smart applications that simplify users’ tasks and also learn and improve from their interaction with users.
