In this case the specialized knowledge was acquired by interviewing with the human experts who are the neurologist and his staff at stroke unit Dr. Sardjito Hospital at Yogyakarta. In addition, the specialized knowledge was also taken from the printed and electronics documents about stroke diseases. Having these knowledge, the knowledge based and others components of the expert system were built according to the steps of building expert system.
