Finding Structural Dependency: A Study of Bangla NPI ar

Negative Polarity Items or NPIs are an important means to signal the kind of coherence relation holding between adjacent text spans. Research on NPIs has been mainly concerned only with its nature of dependency with negation or negative like environments whereas the other dependencies, such as with the presupposition or aspectual, that some of NPIs share have not received much attention. In this paper, we identify semantic and pragmatic features that are required to support a motivated choice of NPI in a conversational situation. The paper tries to address this issue with an emphasis on Bangla NPI ar . In due course the current work will illustrate how Bangla NPI ar can be used to produce alternative verbalizations of the temporal relationship holding between two events.
