基于俄媒语料库的新冠肺炎主题词与疫情变迁研究

Corpus-based Study on the Changes of Key Words and Epidemic Situations of COVID-19 in Russian Media

作者选取中国新冠疫情爆发与相持阶段俄罗斯媒体的相关报道,构建小型语料库,以此为基础,进行了两方面研究:首先,将语料分为3个时期,9个阶段,使用Python数据包提取信息贡献度,归纳每一阶段最高贡献度的50个词汇的语义场,并以实际语料的批评话语分析进行验证,研究俄媒对中国疫情报道主题的变迁;其次使用Wordless软件制作整体语料的词云图,研究2020年1月9日至2020年3月16日期间俄媒关注焦点的一致性问题。研究发现,俄媒疫情报道主题词的发展和变迁经历了3个时期,每一时期俄媒均表现出支持中国抗疫的积极态度,且各时期、各时间段的关注焦点均与本时期的重要事件具有高相关度;中国疫情描述及其对俄罗斯经济的影响是俄媒持续关注的话题。研究为基于语料库的俄语话语研究及中国新冠肺炎疫情期间的俄罗斯社会态度和意识形态问题提供了有效的样例。
