本文分析了《纽约时报》反恐语料库,计算得出高主题性的介词主题词against,其搭配词和索引行分析指向《纽约时报》反恐报道的议题与日程。其中,恒定搭配词和反复出现的索引行体现了反恐话语中的经常性议题,而季节性搭配词和索引行中的变化揭示了每年美国政府反恐策略上重心的调整;同时,against的搭配词和索引行分析揭示出美国三届政府在反恐问题上不同的意识形态倾向。本研究证明对介词等封闭词类的分析可以揭示出语料的宏观特征。
This article analyzes the “New York Times” anti-terrorism corpus and calculates a highly thematic prepositional keyword against, its collocation and index line analysis pointing to the “New York Times” anti-terrorist report topics and schedules. Among them, constant collocation words and recurring index lines reflect the recurring issues in anti-terrorism discourse, while changes in seasonal collocation words and index lines reveal the adjustment of the annual center of gravity of anti-terrorist strategy by the U.S. government. Meanwhile, And the analysis of the index line reveals the different ideological tendencies of the three U.S. governments over the fight against terrorism. This study proves that the analysis of prepositions and other closed words can reveal the macro features of the corpus.
