Recent years have witnessed the prosperous development of tools that process natural language text in social media. Many of them, such as web search and instant messaging, have become part of users' life. When using these tools, users leave trails when surfing the web, including both objective and subjective textual information, which we can develop techniques and applications accordingly. The facilitation of the social media environment, like many other environments which can leverage artificial intelligence techniques, could be further enhanced with applications that can well-service and hence engage users, where resonance play a role.
In this talk I will focus on how we create resonance not only between users but also between users and the developed system by developing the techniques of sentiment analysis, stance classification, and web post recommendation. I will introduce our work on these research problems from the dataset construction, model design and learning, to system deployment. I will illustrate by examples how recent advances in deep learning can benefit user's emotion and preference learning in a language independent way. As the social media is rife with non-linguistic data, I will also report on our progress and several future directions of learning from heterogeneous features.
