About

Hi! My name is Lingjia Deng. I am a fifth-year PhD student in Intelligent System Program at University of Pittsburgh since Fall 2011. Currently I'm working with Dr. Jan Wiebe. Welcome to check our groups's work of MPQA in sentiment analysis and opinion mining. Here is my CV.

Prior to coming to U Pitt, I obtained my Bachelor's degree in Intelligent Science & Technology at Beijing University of Posts & Telecommunications (BUPT), in June 2011.

Research

My research interests include Natural Language Processing and Machine Learning, focusing on opinion mining and sentiment analysis. Currently I am interested in opinion extraction and inference, especially opinions related to a common type of event. We name the event as "+/- Effect Event", which either benefit or harm the theme (object) of the event. Such event is quite common in online political editorials. People may not express their opinions directly, but rather present their stances toward one of the entities involed in such event. By inference, we can analyze people's opinions of the other entities in the event. For a detailed explaination, please refer to our coding manual. The corpus is also available online.
