摘要

本研究采用主题建模法研究新闻媒体情绪与房价走势之间的关系。通过研究加拿大和澳大利亚 16 个主要城市当地报纸上发表的房地产相关文章，我们发现在加拿大市场，住房媒体情绪与未来房价走势有显著关系，而在澳大利亚市场则没有。我们确定了新闻媒体讨论的与房地产市场相关的特定主题，并报告了加拿大和澳大利亚在主题和媒体情绪预测力方面的差异。这项分析对两个不同国家与住房市场相关的定性和难以量化的信息进行了新颖的推断。

Unpacking the relation between media sentiment and house prices: A topic modeling approach

This study uses a topic modeling approach to investigate the relation between news media sentiment and house price movements. By examining real estate related articles published in local newspapers of 16 major cities in Canada and Australia, we find that housing media sentiment has significant relation with future house price movements in the Canadian market but not in the Australian market. We identify the specific topics discussed in news media related to the housing market and report differences in their themes and media sentiment's predictive power between Canada and Australia. This analysis presents novel inferences of qualitative and hard-to-quantify information related to the housing market in two different countries.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
