英文摘要：
  Online activity of the Internet users has been repeatedly shown to provide a rich information set for various research fields. We focus on the job-related searches on Google and their possible usefulness in the region of the Visegrad Group -- the Czech Republic, Hungary, Poland and Slovakia. Even for rather small economies, the online searches of their inhabitants can be successfully utilized for macroeconomic predictions. Specifically, we study the unemployment rates and their interconnection to the job-related searches. We show that the Google searches strongly enhance both nowcasting and forecasting models of the unemployment rates.

中文摘要：
互联网用户的在线活动已被反复证明为各个研究领域提供了丰富的信息集。我们关注谷歌上与工作相关的搜索，以及它们在维谢格拉德集团所在地区——捷克共和国、匈牙利、波兰和斯洛伐克——可能的有用性。即使是规模较小的经济体，其居民的在线搜索也可以成功地用于宏观经济预测。具体而言，我们研究了失业率及其与工作相关搜索的关联。我们发现，谷歌搜索大大增强了失业率的即时预测和预测模型。
