新闻消费者希望新闻媒体在报道事件时客观、平衡。然而，有大量证据表明，媒体中的偏见是由潜在的政治和社会经济观点造成的。以往的研究试图对媒体的广告性进行分类，有时会给出定量的评价，但对其本质的研究却鲜有报道。社交媒体中的大量内容使我们能够量化媒体对政治光谱任何一方的倾向。为了描述这种趋势，我们使用推文来自动计算新闻媒体的政治和社会经济取向。我们表明，媒体有一个可衡量的偏见，并说明了这一点，在这个国家的执政党的智利媒体的偏袒。我们还发现，偏见的性质反映在不同新闻媒体使用的词汇和提到的实体中。在新闻消费者中进行的一项调查证实，媒体偏见对有争议的话题的报道有影响，这是普通观众可以察觉到的。有一个更准确的方法来衡量和描述媒体偏见，将向读者澄清媒体在社会经济格局中的地位，即使是在自我声明的立场。这将使读者能够更好地反映他们选择的新闻媒体提供的内容。
News consumers expect news outlets to be objective and balanced in their reports of events. However, there is a body of evidence of bias in the media caused by underlying political and socio-economic viewpoints. Previous studies have tried to classify the partiality of the media, sometimes giving a quantitative evaluation, but there is little reported on its nature. The vast amount of content in the social media enables us to quantify the inclination of the press to either side of the political spectrum. To describe such tendencies, we use tweets to automatically compute a news outlet's political and socio-economic orientation. We show that the media have a measurable bias, and illustrate this by showing the favoritism of Chilean media for the ruling political parties in this country. We also found that the nature of the bias is reflected in the vocabulary used and the entities mentioned by different news outlets. A survey conducted among news consumers confirms that media bias has an impact on the coverage of controversial topics and that this is perceivable by the general audience. Having a more accurate method to measure and characterize media bias will clarify to the readers where outlets stand within the socio-economic landscape, even when a self-declared position is stated. This will empower readers to better reflect on the content provided by their news outlets of choice.
