日本語日常会話コーパスにおける推量副詞とモダリティ形式の働き

要旨

The phenomenon of the correspondence between suppositional adverbs and sentence-final modalities, as well as their distant collocational relations, has already been discussed in previous research (Minami 1974, Kudo 2000, Bekeš 2006, Srdanović et al. 2008, Srdanović et al. 2009a, b, c, Hodošček et al. 2010). Empirical studies using multiple Japanese corpora have confirmed that the distribution of adverbs and their co-occurrence with sentence-final modality forms vary by corpus genre and are characterized by different degrees of modality types (Srdanović et al. 2009a, b, c, Hodošček et al. 2010). The aim of this study is to investigate these phenomena within the Corpus of Everyday Japanese Conversation (CEJC) (Koiso et al. 2022), and, by comparing it with other corpora, to show the distribution of suppositional adverbs and clarify their behavior along with modality. This study provides an analysis of modality forms extracted from the CEJC and confirms their diversity and stylistic features distinct from written language. Examination of modality forms in utterances containing suppositional adverbs, including their extended preceding and following contexts, reveals a clear correspondence with typical high-frequency modality types and the emergence of various modality forms and types that play significant roles in discourse. The results further clarify the behavior of adverbs and modality in conversation, with implications for fields such as Japanese language education, discourse analysis, and pragmatics.
