摘要翻译:
我们表明,对报纸网站上的金融评论的幂律分析可以用来识别股市泡沫,补充传统的波动性分析。我们使用了来自英国《金融时报》、《纽约时报》和英国广播公司的17713篇在线金融相关文章(1000万+字)的四年语料库,表明幂律分布的每周变化反映了道琼斯工业平均指数(DJI)、富时100指数和日经225指数的市场变化。值得注意的是,语言的统计规律跟踪了2007年股市泡沫,显示了评论员语言中的新兴结构,因为他们对市场的积极看法越来越一致。此外,在泡沫时期,Kullback-Leibler的分析揭示了积极语言的显著差异。

分类描述:Covers natural language processing. Roughly includes material in ACM Subject Class I.2.7. Note that work on artificial languages (programming languages, logics, formal systems) that does not explicitly address natural-language issues broadly construed (natural-language processing, computational linguistics, speech, text retrieval, etc.) is not appropriate for this area.

英文摘要:
We show that power-law analyses of financial commentaries from newspaper web-sites can be used to identify stock market bubbles, supplementing traditional volatility analyses. Using a four-year corpus of 17,713 online, finance-related articles (10M+ words) from the Financial Times, the New York Times, and the BBC, we show that week-to-week changes in power-law distributions reflect market movements of the Dow Jones Industrial Average (DJI), the FTSE-100, and the NIKKEI-225. Notably, the statistical regularities in language track the 2007 stock market bubble, showing emerging structure in the language of commentators, as progressively greater agreement arose in their positive perceptions of the market. Furthermore, during the bubble period, a marked divergence in positive language occurs as revealed by a Kullback-Leibler analysis.
