“…As a fast growing sub-field of computational argumentation mining [35,41], previous work in this area mostly work on the identification of convincing arguments [13,44] and viewpoints [14,19] from varying argumentation genres, such as social media discussions [37], political debates [4], and student essays [6]. In this line, many existing studies focus on crafting hand-made features [37,44], such as wordings and topic strengths [43,53], echoed words [2], semantic and syntactic rules [15,30], participants' personality [42], argument interactions and structure [29], and so forth. These methods, however, require labor-intensive feature engineering process, and hence have limited generalization abilities to new domains.…”
