In this pa- per, we propose an Opinion PageRank model and an Opinion HITS model to fully explore the information from different re- lations among questions and answers, ... graph model as a condition. The second model, called Opinion HITS model, considers the sentences as authorities and both question topic information and opinion sentiment information as hubs. The experiment ... they contain. We propose to com- pute the conditional similarity score by linearly combining the scores conditioned on the source opinion (i.e. f(i → j|Op(v i ))) and the destina- tion opinion (i.e....
