管窥百年普利策：基于普利策新闻奖嘉奖辞的词频分析（1917-2016）
A Glimpse of Pulitzer Prize: An Analysis of the Word-Frequency on Citation of Pulitzer Prize for Journalism (1917-2016)

摘要 本研究通过词频分析法，考察1917年至2016年美国普利策新闻奖获作品的嘉奖辞。研究发现，作为普利策评审委员会对获奖作品的专业评述，一百年来嘉奖词中的词频呈现一定的稳定性和持续性；同时，在不同总统和不同政党的执政期内，嘉奖词中的词频又显现出差异性。这在某种程度上表明，百年来普利策新闻奖评审遵循并适当调整着自己的专业标准，由此影响普利策新闻奖这一美国新闻业最高荣誉体系的构建。
