With the rise of AI, the importance of data is being recognized again, and various data are openly released and can be used easily.
The existence of open data is essential for machine learning that learns from huge amounts of data, and it is necessary to select and utilize open data according to the AI you want to build.
On the other hand, open data alone cannot build AI with competitive advantage. It is important to build a unique AI by combining macro open data and independently collected micro data.
When building a service that utilizes open data, the key is to improve the UX (user experience) of the service and how unique data can be obtained, so don’t rely too much on open data.
This time, we classified 100 open data datasets into 6 categories. Look for data that can be used to build your own service or AI.
