SmarTag is ChinaScope’s flagship news analysis engine that deconstructs unstructured Chinese language text into structured machine-readable metadata and sentiment analysis. This data brings accessibility to Chinese news by allowing users to consume and aggregate sentiment indicators for news linked to Chinese companies.
ChinaScope leverages its Mandarin language expertise to extract financial news from over 380 media outlets in near real time and tag relevant Chinese companies, products, industries, events and concepts. A positive, neutral and negative sentiment indicator is provided for both the news article and the specific company tagged to the article.

Data Methodology
ChinaScope manages a rigorous process of news extraction, filtering, analysis and tagging to create the SmarTag product. Financial news is captured every five minutes from over 380 media outlets and over 3,200 web pages, using a proprietary web crawler. Each webpage is vetted for relevance to the financial industry and site stability. Once extraneous noise, such as advertisements, and duplicate news is removed, articles are tagged to related entities, such as companies, industries, events, products and concepts. The companies tagged include China A-shares, Hong Kong stocks and those listed on the NEEQ market, NYSE and NASDAQ.
The sentiment analysis process derives positive, negative and neutral sentiment scores at the article level and for each entity tagged to the article. In the course of standardizing this information, the Chinese language is retained, and the metadata is translated to English for widespread consumption across users and regions.
