| Research Abstract |
We proposed a new method of extracting tuples of an object, its attribute, and an evaluative expression from a document, by leveraging the techniques in semantic role labeling. Since structured output learning is considered to be a promising method in semantic role labeling, our method is also based on it. Furthermore, we proposed a new sentiment summarization method that aggregates a set of pairs of an attribute and an evaluative expression, by taking into account their synonym relationships. The proposed method is based on the model
that we proposed for text summarization, based on Facility Location Problem.
