Through the social media registered by the adopter, analyze the associations and fan pages that adopters have joined, and evaluate the degree of friendly animals. According to the photo albums, marked objects and characters published on the Internet by the adopter, it is inferred whether the adopter is a suitable adopter.

The system uses the government's public information to analyze that if the adopter has a criminal history related to violence, the adoption application will be declined, and a database of "potential animal abusers" will be established to prevent abusers from adopting pets in advance.
