... Word pairs can maintain intra-sentence contextual information to express the potential relevant opinions. In addi- tion, inter-sentence contextual information is also captured by word pairs ... relevant to the target concerned. Therefore, we argue that existing information representation i.e. bag-of-word, cannot satisfy the information needs for opinion retrieval. In this paper, ......
