I just completed an upload of 50 card, of which about 75% required me to reassign the card name. This was because there was no existing photo in the system so your system could not properly identify the card. Now that I have added a photo and properly identified the card I'm sure that means that future user will benefit from my upload. I would suggest that you reward users that upload and properly identify new cards that ultimately benefit you business. The reward could simply be one additional upload for the month. That would encourage me to take the time to correct the listing within your system. Another systems listing tool was able to properly identify all of the them. Providing a simple benefit of an extra listing when I help you programs machine learning would go a long way. If the accuracy rate is as poor as 25%, I don't have much incentive not to just uses other listing tools.
