Recently, natural language processing (NLP) has had increasing success and produced extensive industrial applications. Despite being sufficient to enable these applications, current NLP systems often ignore the structures of language and heavily rely on massive labeled data. In this talk, we take a closer look at the interplay between language structures and computational methods via three lines of work. The first one studies what makes language persuasive by introducing a semi-supervised method to leverage hierarchical structures in text to recognize persuasion strategies in good-faith requests on crowdfunding platforms. We then show how to incorporate linguistically-informed relations between different training data to help both text classification and sequence labeling tasks when annotated data is limited. The last part demonstrates how various structures in conversations can be utilized to generate better summaries for everyday interaction.
