Media discourse is an effective tool for projecting and shaping the public perception of a certain idea or image. The article focuses on the linguistic and semantic representation of the concept “Black” in the American media discourse with a particular attention to how the concept representation has evolved from the 1990s to 2010s. The study employed corpus methodology (keyness, frequency, concordances) to analyze news articles from “The New York Times” and “The Los Angeles Times”, which were arranged into three corpora according to the publication date (1990s, 2000s, 2010s). The corpus analysis established a number of changes in the concept “Black” representation manifested primarily through the high relevance keywords and high frequency collocations. Dominant semantic components were identified in the concept representation in each corpus, as well as notable shifts in core and peripheral aspects within these semantic components. The analysis showed that although the semantic components ‘racial / ethnic inequality’ and ‘economic issues’ remain at the core of the concept in each corpus, they are expressed through connections with other semantic components which may vary throughout three decades, such as ‘culture’ in the 1990s, ‘education’ and ‘politics’ in the 2000s and ‘police brutality and profiling’ and ‘appearance’ in the 2010s.

美国媒体话语中“黑色”概念的演变

媒体话语是投射和塑造公众对某个想法或形象的看法的有效工具。本文重点关注美国媒体话语中“黑人”概念的语言和语义表征，特别关注概念表征从 1990 年代到 2010 年代的演变过程。本研究采用语料库方法（keyness、frequency、concordances）分析《纽约时报》和《洛杉矶时报》的新闻文章，按照发表日期（1990年代、2000年代、2010年代）分为三个语料库。语料库分析确定了“黑色”概念表示的一些变化，主要表现在高相关性关键词和高频搭配上。在每个语料库的概念表示中识别出主要语义成分，以及这些语义组件中核心和外围方面的显着变化。分析表明，尽管语义成分“种族/民族不平等”和“经济问题”仍然是每个语料库中概念的核心，但它们是通过与其他语义成分的联系来表达的，这些成分在三个十年中可能会有所不同，例如“文化”。 ”在 1990 年代，“教育”和“政治”在 2000 年代，“警察暴行和貌相”和“外表”在 2010 年代。
