WordNet-Based Inference of Textual Cohesion and Coherence

Sanda M. Harabagiu

"In this paper I presents a computational method for the recognition of the cohesive and coherence structures of texts. A large lexical knowledge base built oil top of WordNet provides with the lexico-semantic information that needs to be mined. A path-finding algorithm returns the cohesive structure of a text with results that outperform previous approaches. The Iexical paths contained in the cohesive structures are used to (1) build patterns of association between cue phrases and coherence relations and (2) to find the lexical characterist.ics of coherence categories. Finally. the textual coherence structure is recognized by giving priority to the coherence constrains induced by cue phrases. The paper presents also the performance of building the coherence structure for several texts.
