초점 현상 분석에 의한 통사구조, 정보 구조, 담화구조의 관련성 탐구

  It is proposed that the informational categories that have been traditionally referred to as topic, contrastive topic, and focus are defined in terms of twoinformational primitive features, {+-topical, +-focal}. Four possible informational categories, namely [+t, -f], [+t, +f], [-t, +f], and [-t,-f], are yielded from this binary feature system, which exhaustively categorize the informational status of each part of a sentence. An integrated analysis for the two categories, namely focus and focus frame that are defined as [-t, +f] and [-t, -f], respectively, is proposed, based on the semantic, syntactic, and discoursal considerations. This incorporates the semantic function of [+f] as the identificational predication and its corresponding syntactic structure interacting with the discourse context. The information conveyed by the category[-t, -f] is interpreted as having the widest scope among the four categories, which is accounted for by its anaphoric property licensed by the antecedent entailed in the previous context.
