One facet of our proposed strategy for enhancing information access to troubleshooting-oriented web user forum data is to preprocess threads to uncover the "content structure" of the thread, in the form of its post-to-post discourse structure.
we identify which earlier post(s) a given post responds to (linking) and in what manner (tagging), in an amalgam of dialogue act tagging (Stolcke et al., 2000) and coherence-based discourse analysis (Carlson et al., 2001;Wolf and Gibson, 2005).
