This document presents a novel technique for finding related discussion posts on forums by segmenting each post into sections based on the intention of the author. Each section aims to convey a different message or objective. Relatedness between posts is determined by comparing sections that share the same intention, rather than comparing the full text of posts. The technique involves identifying sections within each post using linguistic and semantic cues. Sections with the same intention are then clustered together. The effectiveness of this intention-based segmentation for suggesting related forum posts is evaluated on real user data from different domains. The proposed approach is found to be more effective at determining post relatedness than direct text comparisons of full posts.
