Title: Using Natural Language Processing for Exploring Social Interaction and its Applications
Date: 2021-04-09 2:20pm-3:30pm
Location: R103, CSIE
Speaker: Prof. Yung-Chun Chang, Taipei Medical University
Hosted by: Prof. Vivian Chen
The topics in a set of documents is constituted by a series of person interactions at a specific time and place. Knowing the interactions between the individuals mentioned in these documents is helpful for readers to better comprehend the documents. This talk will introduce a novel task that aims at recognizing person interactions in Chinese documents. Instances of these interactions characterize different types of human behaviors that may contribute to the recognition and influence between one another. To discover social interactions, we need a detection method that can identify text segments containing information about these interactions. Information extraction algorithms then analyze the segments to extract interaction tuples and construct an interaction network of topics as well as persons. Paired with data visualization techniques, we can easily identify key components within this complicated network. The novel tasks, methodology, and potential applications will be presented in this talk.
