摘要
To highly accurately construct a discourse structure tree regardless of the number of EDUs.SOLUTION: An in-sentence analysis unit 32, on the basis of parameters of a learned model for estimating EDU vectors each representing each elementary unit of an elementary unit sequence, positions at which the elementary unit sequence is divided into two spans, and combinations of nonterminal symbols given to each of the two spans, divides the elementary unit sequence into two spans, recursively repeats the estimation of the combinations of nonterminal symbols given to each span and the relation labels of the spans, and outputs an in-sentence discourse tree, which is a discourse structure tree using elementary units as units. An in-paragraph analysis unit 34 outputs an in-paragraph discourse tree, which is a discourse structure using sentences as units. An in-document analysis unit 36 outputs an in-document discourse tree, which is a discourse structure tree using paragraphs as units. A tree coupling unit 38 outputs a discourse structure tree in which are coupled the structures of the elementary units, sentences, and paragraphs of the document on the basis of the in-sentence discourse tree, the in-paragraph discourse tree, and the in-document discourse tree.SELECTED DRAWING: Figure 3
