Brief Summary

The fight against the spread of the 2019-nCoV epidemic has achieved some success in China, but the epidemic is far from over. A key factor making the epidemic under control in China is the government's call for social distance, which has led to few people going out for donation. As a result, the number of blood donors on the streets has been continuing to decline. Urgent recruitment of blood donors is therefore planned during the period from 30 April to 10 May via emergency recruitment SMS . This study has been designed to compare which information extraction frameworks would be more sensitive to blood donors in emergency situations.

The literature shows that the information extraction and processing in emergency is different from the normal situation. To find the most effective emergency recruitment method during an outbreak, we intervened with a well-balanced group of donors by presenting different emergency recruitment text messages.
