Báo cáo khoa học: "Social Network Extraction from Texts: A Thesis Proposal" doc

... overall goal of my thesis is to build a system that automatically extracts a social network from raw texts such as literary texts, emails, blog comments and news articles. I take a “social net- work” ... to extract social networks from a wide range of textual data.
