Institutions have a large number of self-built resources: if institutions or schools have a large number of self-built resources, such as papers of previous students, internal databases, etc. Then you can upload and manage these resources with the self-built database, which is convenient for comparison and duplicate checking.
Special majors or fields: Some special majors or fields, such as medicine and law, need to use the self-built database to establish the corresponding professional comparison database to improve the accuracy and efficiency of duplicate checking.
Personalized requirements: Some users may have personalized requirements, such as a large amount of data to be compared, or need to upload and compare some specific resources, so self-built libraries can better meet these needs.
