  To easily obtain the knowledge about autism spectrum disorder and help its
early screening and diagnosis, we create AsdKB, a Chinese knowledge base on
autism spectrum disorder. The knowledge base is built on top of various
sources, including 1) the disease knowledge from SNOMED CT and ICD-10 clinical
descriptions on mental and behavioural disorders, 2) the diagnostic knowledge
from DSM-5 and different screening tools recommended by social organizations
and medical institutes, and 3) the expert knowledge on professional physicians
and hospitals from the Web. AsdKB contains both ontological and factual
knowledge, and is accessible as Linked Data at https://w3id.org/asdkb/. The
potential applications of AsdKB are question answering, auxiliary diagnosis,
and expert recommendation, and we illustrate them with a prototype which can be
accessed at http://asdkb.org.cn/.
