摘要翻译：
经济学家对使用文本作为经济研究的投入表现出越来越大的兴趣。在这里，我们分析在线文本来构建一个实时的福利度量。为了描述的目的，我们称之为感觉良好因素(FGF)。用于说明这一概念的具体例子仅限于伦敦地区的数据，但这一方法很容易推广到其他地理区域。FGF说明了如何利用在线数据来建立一种福利衡量标准，而不是像国内生产总值那样，以市场经济中的增值为基础。已经有大量的文献来衡量幸福/快乐。但这依赖于传统的调查方法，因此依赖于受访者陈述的偏好。在非结构化的网络媒体文本中，用户以类似于消费需求理论中揭示偏好原则的方式来揭示他们的情感。对网络媒体的分析比传统的基于调查的情绪或幸福感测量提供了更多的优势。它可以实时进行，而不是在调查方法中涉及的滞后情况下进行。此外，它也便宜得多。

英文摘要：
  Economists are showing increasing interest in the use of text as an input to economic research. Here, we analyse online text to construct a real time metric of welfare. For purposes of description, we call it the Feel Good Factor (FGF). The particular example used to illustrate the concept is confined to data from the London area, but the methodology is readily generalisable to other geographical areas. The FGF illustrates the use of online data to create a measure of welfare which is not based, as GDP is, on value added in a market-oriented economy. There is already a large literature which measures wellbeing/happiness. But this relies on conventional survey approaches, and hence on the stated preferences of respondents. In unstructured online media text, users reveal their emotions in ways analogous to the principle of revealed preference in consumer demand theory. The analysis of online media offers further advantages over conventional survey-based measures of sentiment or well-being. It can be carried out in real time rather than with the lags which are involved in survey approaches. In addition, it is very much cheaper.
