汉语语篇理解中元指代消解初步

Anaphoric resolution is a hot field in computational linguistics. According to the research, it is found that a kind of anaphora, meta-anaphora, which represents the form of sentence, paragraph or discourse (not the subject or object of the sentence), plays an important role in discourse. So meta-anaphoric resolution affects the computer s ability of discourse understanding. This paper focuses on the meta-anaphoric resolution. A new concept called Elementary Event focus (EE_focus) is introduced. And some meta-anaphoric resolition algorithms based on the concept are desinged.The algorithms examined by a large Chinese natural language corpus.The experimental results show that the EE_focus set can do good job in meat-anaphoric resolution.The workenriches the theory of discourse's structural representation.It is important in comfirming the cohesion and coherence of the Chinese discourses.
