Dr Audrey Masizana-Katongo is a computer scientist and has been involved in the creation of indigenous knowledge databases. Recently, she developed a new concept of “expert systems” in relation to traditional medical knowledge. Contrary to classical input-output-based databases, an “expert system” can store intermediate steps that lead to certain conclusions. She currently tests applications of this “expert system” on storing information on traditional healer’s diagnostic steps culminating in a final patient diagnosis.
