... 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 needs for opinion ... the documents, and none on how to represent the information needs re- quired to retrieve opinionated documents. In this paper, we focus on opinion retrieval, whose goal is to find a se...

In this case we observe a small boost in performance for the detection ... candi- dates? Since no parser currently exists for the TDS representation, we utilize a state of the art parser for PS trees (Charniak, 1999), and transform each candidate to TDS. T...
