语言障碍群体的语言政策是中国语言文字事业发展的重要议题之一,厘清中国语言障碍群体的语言政策布局,对于应对其语言问题具有纲领性作用。本研究依托北大法宝数据库,创建了中国语言障碍群体的语言政策语料库,归纳中国语言障碍群体的语言政策文本整体特征。通过基于Python的自然语言处理方法,采用LDA主题模型和TF-IDF算法,从时间与空间维度深入分析中国语言障碍群体的语言政策文本。研究主张加强顶层设计,整合语言政策体系;统一称谓,推动社会理念转变;构建语言政策反馈渠道,切实服务语言障碍群体。本研究尝试为完善语言障碍群体的语言政策体系以及构建信息无障碍社会提供参考。

Language policy for language disorders is one of the crucial issues in the development of China’s language affairs. Clarifying the language policy layout for the language disorder plays a pivotal role in solving their language problems. Based on the PKU Law Database, this study creates a language policy corpus for language disorders. It summarizes the general characteristics of language policy texts for language disorders. It uses Python’s natural language processing methods for LDA model and TF-IDF algorithm analysis of the self-generated corpus. The study analyzes the language policies for language disorders from temporal and spatial dimensions. It advocates strengthening the top-level design and integrating the language policy systems; unifying the terminology and promoting social ideology transformation; establishing language policy feedback channels to effectively serve language barrier communities, and providing a reference for improving the language policy system for language disorders and constructing an information-accessible society.
