... difference is that the three levels in their model form a hierarchy, with discourse plans always rooted in exploration plans. While this may be appropriate for information-seeking discourse, allowing ... to be recognized and modeled. DISCOURSE MODEL LEVELS In task-related discourse, much of the discourse structure derives directly from the task structure, so that a model of t...

The model used sentiment ... opinions in the document are indeed relevant to the target concerned. Therefore, we argue that existing information representation i.e. bag-of-word, cannot satisfy the information n...
