Abstract :
In this paper we discuss the application of the Linguistic Discourse Model (LDM) to sentiment analysis at the discourse level. Based on the observations that naturally occurring discourse is interpretable though often not coherent, the LDM provides a unified and explanatory approach to discourse sentiment assignment. Special attention is paid here to the well known problem of computing sentiment in movie reviews which are characterized by shifting contexts of sentiment source and target.
