随着网络化时代的推进,大学生社会交往深受互联网影响,“大学生圈群”成为高校普遍存在的社交现象。使用Python采集知乎和百度贴吧平台上以大学生社交为主题的文本为数据源,采用BERTopic主题建模,以识别大学生社交的主题分布及提取其主题特征,分析不同时间序列上的主题内容演化趋势。研究发现,大学生社交话题呈现出显著的多元化与圈层化,核心主题可归纳为4个社交领域:人际交往社交、职业发展社交、学习合作社交和现实焦虑社交。演化分析表明,大学生的核心诉求与心态变化在不同阶段发生着规律性演变。将BERTopic模型应用于大学生社交领域的动态主题演化分析,有效捕捉了圈层语境下话题的细粒度特征与时序性规律。未来研究可进一步结合多模态数据探索主题演化与特定社会事件的关联性。
