Welcome to CnOpenData!

The Birth of CnOpenData

Initially, we had occasional opportunities to offer data collection and sorting services to some university and college teachers. Over the past few years, we have gradually established stable collegial partnerships with many university and college teachers, which has led to us becoming reasonably well known. Motivated by the increasing demand for data services, we decided to build a data platform to address these needs more broadly.

The Internet generates and stores massive amounts of data and information, and presents this to the public. However, scholars encounter many problems when using data from the Internet, such as problems in selecting, collecting, and organizing the data they require from the huge volumes of data that are available. As IT professionals, we are highly proficient at addressing such data-related challenges. We have also benefited from the support we have received from the professional academic teams who were once our clients but are now our consultants.

Simplicity, clarity, and usefulness are our goals. In a world pervaded by digital technologies, data is akin to gold nuggets that are scattered everywhere; our role is to mine these nuggets, and make them available to researchers. We look forward to working with you to explore the value of data, and to help you to find the data you need.
