TAILIEUCHUNG - Báo cáo khoa học: "Subjective Natural Language Problems: Motivations, Applications, Characterizations, and Implications"

This opinion paper discusses subjective natural language problems in terms of their motivations, applications, characterizations, and implications. It argues that such problems deserve increased attention because of their potential to challenge the status of theoretical understanding, problem-solving methods, and evaluation techniques in computational linguistics. The author supports a more holistic approach to such problems; a view that extends beyond opinion mining or sentiment analysis. | Subjective Natural Language Problems Motivations Applications Characterizations and Implications Cecilia Ovesdotter Alm Department of English College of Liberal Arts Rochester Institute of Technology coagla@ Abstract This opinion paper discusses subjective natural language problems in terms of their motivations applications characterizations and implications.

Language analysts including computational linguists have long acknowledged the importance of such topics Buhler 1934 Lyons 1977 Jakobson 1996 Halliday 1996 Wiebe et al 2004 Wilson et al 2005 .

The terms subjectivity or subjectivity analysis are also established in the NLP literature to cover these topics of growing inquiry. The purpose of this opinion paper is not to provide a survey of subjective natural language prob 107 lems. Rather it intends to launch discussions about how subjective natural language problems have a vital role to play in computational linguistics and in shaping fundamental questions in the field for the future. An additional point of departure is that a continuing focus on primarily the fundamental distinction of facts vs. .
