Data scientists in China are using big data relating to daily web searches to help build a better picture of the country's economy. The world's largest trading nation lacks key economic metrics like survey-based unemployment rates and private manufacturing indicators and official statistics are often unreliable or incomplete. Hence, global investors are looking to big data from operators such as online search engine Baidu, card processor China UnionPay or e-commerce giant Alibaba to gain a clearer understanding of the Chinese economy.
