基于LDA主题模型的我国养老服务政策文本分析
Text analysis of China's senior care service policy based on LDA topic modeling
摘要
Abstract
With the deepening of population aging,policies related to senior care services have been successively introduced,and the focus of policies has been adjusted with the times.This paper selects 44 policy texts related to senior care service issued from 2015 to 2025 as samples,and applies the Latent Dirichlet Allocation(LDA)topic model to capture the core themes of the selected policy texts for hot topic identification and classification.This paper aims to conduct an in-depth analysis of the development direction and trend of the Chinese government in the supply of senior care service,revealing the release patterns and theme characteristics of these policies.7 key themes were formed in the analysis,with keywords focusing on"health""community""society""encouragement"and other contents,which were divided into three categories:senior care service supply,senior care industry and basic senior care service.It is concluded that the senior care service should advance in three key areas,including establishing a multi-level care system and strengthening service supply supervision;diversifying the industrial form to promote a comprehensive development of senior care;and improving the compatibility between supply and demand to ensure the long-term progress of basic senior care service.As a result,these measures will contribute to the high-quality development of China's senior care system.关键词
