Abstract

AbstractWhile there has been substantial progress in text comprehension through simple factoid question answering, more holistic comprehension of a discourse still presents a major challenge (Dunietz et al., 2020). Someone critically reflecting on a text as they read it will pose curiosity-driven, often open-ended questions, which reflect deep understanding of the content and require complex reasoning to answer (Ko et al., 2020; Westera et al., 2020). A key challenge in building and evaluating models for this type of discourse comprehension is the lack of annotated data, especially since collecting answers to such questions requires high cognitive load for annotators. This paper presents a novel paradigm that enables scalable data collection targeting the comprehension of news documents, viewing these questions through the lens of discourse. The resulting corpus, DCQA (Discourse Comprehension by Question Answering), captures both discourse and semantic links between sentences in the form of free-form, open-ended questions. On an evaluation set that we annotated on questions from Ko et al. (2020), we show that DCQA provides valuable supervision for answering open-ended questions. We additionally design pre-training methods utilizing existing question-answering resources, and use synthetic data to accommodate unanswerable questions.

Despite consensus that idiosyncratic fac- tors play a key role in regulating how listeners emotionally respond to music, precisely mea- suring the marginal effects of these variables has proved challenging. To address this gap, we develop computational methods to measure affective responses to music from over 403M listener comments on a Chinese social music platform. Building on studies from music psy- chology in systematic and quasi-causal anal- yses, we test for musical, lyrical, contextual, demographic, and mental health effects that drive listener affective responses. Finally, moti- vated by the social phenomenon known as 网抑 云 (wˇang-yì-yún), we identify influencing fac- tors of platform user self-disclosures, the social support they receive, and notable differences in discloser user activity. 1 Introduction Music can evoke powerful emotions in listeners (Meyer, 1956). However, our emotional reactions to it are not universal—affective responses to mu- sic are highly personal. Just as you may wonder why your friend is sobbing to a song that you only feel ambivalent about, a listener’s emotional re- sponse to music not only varies with inherent au- dio or lyrical features (Hevner, 1935; Webster and Weir, 2005; Van der Zwaag et al., 2011), but also with other factors such as a listener’s demograph- ics, mental health conditions, and surrounding en- vironment (Krugman, 1943; Robazza et al., 1994; Gregory and Varney, 1996; Juslin and Västfjäll, 2008; Saarikallio et al., 2013; Garrido et al., 2018). As a result of this idiosyncrasy, it has been ex- tremely difficult to precisely measure the marginal effects of these variables on a listener’s affective response (Yang et al., 2007; Beveridge and Knox, 2018). This difficulty is further compounded espe- cially when examining how a collection of these factors influence individual affective reactions in combination (Gómez-Cañón et al., 2021). Music psychology has long focused on identi- fying the relationships between human affect and music, both in those that are perceived and those that are felt. Perceiving and feeling emotions in mu- sic, while highly related, are not identical (Hunter and Schellenberg, 2010). Examining the latter has proved challenging, as in addition to insufficient scale for finding significance, measuring felt emo- tions in participatory studies often interferes with the experience itself (Gabrielsson and Lindström, 2010). While recent computational studies have at- tempted citizen science approaches for annotation (Gutiérrez Páez et al., 2021), reliability remains an issue; annotator confusion persists between the con- cepts of perceived and induced emotions (Juslin, 2019). Our work expands this line of research by examining affective responses to music in a natural setting: an online social music platform. We test for differences in affective responses to music by computationally measuring expressed …
