摘要:

语义复合性是指一个复杂的语言单位的意义可以由其组成成分的意义组合而成的现象。大多数相关的工作集中在使用复杂的组合功能来建模供应链,而很少有工作考虑模型中的外部知识。在本文中,我们验证了语义素,人类语言的最小语义单位,在SC建模的有效性,通过验证性实验。此外,我们第一次尝试将义素知识SC模型,并采用sememeincorporated模型在学习表示的多词表达,一个典型的任务SC。在实验中,我们实现了我们的模型,将知识从一个著名的义素知识库知网和执行内在和外在的评价。实验结果表明,我们的模型实现了显着的性能提升相比,基线方法,不考虑义素知识。我们进一步进行了定量分析和案例研究,以证明义素知识在SC建模中的有效性。本文的所有代码和数据可以在https://github.com/thunlp/Sememe-SC上获得。

英文摘要:

Semantic compositionality (SC) refers to the phenomenon that the meaning of a complex linguistic unit can be composed of the meanings of its constituents. Most related works focus on using complicated compositionality functions to model SC while few works consider external knowledge in models. In this paper, we verify the effectiveness of sememes, the minimum semantic units of human languages, in modeling SC by a confirmatory experiment. Furthermore, we make the first attempt to incorporate sememe knowledge into SC models, and employ the sememeincorporated models in learning representations of multiword expressions, a typical task of SC. In experiments, we implement our models by incorporating knowledge from a famous sememe knowledge base HowNet and perform both intrinsic and extrinsic evaluations. Experimental results show that our models achieve significant performance boost as compared to the baseline methods without considering sememe knowledge. We further conduct quantitative analysis and case studies to demonstrate the effectiveness of applying sememe knowledge in modeling SC. All the code and data of this paper can be obtained on https://github.com/thunlp/Sememe-SC.
