| Abstract(in English) | A Japanese sentence can be expressed as a tree structure (dependency tree) based on dependency relations. Since a subtree of a dependency tree preserves the dependency relations of the original tree, it generally represents a correct sentence on its own. In this paper, a document is expressed as an extended dependency tree, in which weights are assigned to its nodes and edges. Moreover, the problem of extracting important text fragments is formalized as that of "searching for a subtree that maximizes a certain score from subtrees of the extended decision tree". We implemented such a summarization system and performed evaluations based on manual assessment as well as comparison with original texts. |
