内容分析（content analysis）一直以来都是社会科学和媒体研究的传统组成部分。内容分析的自动化通过研究社交媒体和报刊杂志上数百万计的新闻内容，使得“大数据革命”惠及社会科学。性别歧视、可读性、内容相似度、读者偏好、甚至情绪等都文本挖掘方法在数百万文档里研究过了。

[[Content analysis]] has been a traditional part of social sciences and media studies for a long time. The automation of content analysis has allowed a "大数据" 革命 to take place in that field, with studies in social media and newspaper content that include millions of news items. [[Gender bias]], [[readability]], content similarity, reader preferences, and even mood have been analyzed based on [[text mining]] methods over millions of documents.<ref>{{cite journal|author1=I.
