用途

  • An integrated toolkit with a good range of grammatical analysis tools //語法分析工具
  • Fast, reliable analysis of arbitrary texts //文本分析
  • The overall highest quality text analytics
  • Support for a number of major (human) languages
  • Available interfaces for most major modern programming languages
  • Ability to run as a simple web service

這對人文,社會學科會有些影響吧.  文本分析都有工具可以處理了, 分析文本的情緒意向, 是愛是恨? 是贊成是反對? 是同意是不同意? 是支持或不支持?  高盛已有在用這工具了.

這工具是開源, 但注意若要轉用商用或用在自己軟件裡要申請授權(note1),

這工具,廣告公司,民調中心, 經濟政策研究單位會用的到.
