摘　　要：该文研究了基于HowNet的KDML语法体系的术语DEF自动生成问题,提出一种基于树形解码器的生成方法。在编码器端输入专业术语以及其他外部信息(术语的定义、术语子词的义原等);在解码器端交替使用义原解码器和关系解码器,同时使用注意力机制关注编码器端的各种表征信息,最终得到“义原-关系-义原”形式的输出,并组合成术语对应的义原树,进而得到术语的DEF表示以辅助专业领域HowNet的构建,最终取得了首义原F_(1)值74.13%、总义原F_(1)值53.92%、总关系F_(1)值53.33%、总三元组F_(1)值30.48%的结果。This paper investigates the automatic generation of DEF based on KDML of HowNet,and proposes a generation method based on tree-structured decoder.The inputs of the encoder are technical terms and other external information(definition of the terms,sememes of sub-words of the terms,etc.).As for decoding,sememe decoder and role decoder are used alternately,and attention mechanism is used to capture various representation information.Finally,the output in the form of"sememe-role-sememe"is obtained,which is combined into the sememe tree corresponding to terms to finalize the DEF representation of terms in HowNet.Experimental results show that the proposed method achieves 74.13%F_(1)-value for the first sememe generation,53.92%for the overall sememe generation,53.33%for the role generation and 30.48%for the overall triple generation.
