Abstract：Essay generation is a challenging task in natural language generation. Unlike poetry and story generation, the essay generation demands accurate sentence-level semantics, clear argumentation structure and reasonable expression of core arguments. The state-of-art solution in this task,retrieval based method ignores the identification of logical argumentation relations, resulting in semantic incoherence and inversion of argumentation logic. In this paper, we apply proposes an argumentation identification method based on explicit semantic structure information, achieving better results than previous natural language inference models on the argumentation identification dataset. At the same time, the argumentation identification result is used as an explicit feature to apply to the sentence ordering model for essay generation, which effectively alleviates the logical inconsistency of the ordering model in the essay generation dataset and further improves the overall performance of the essay generation system.
