Linguistic approach in medical diagnosis
Đỗ Trung Tuấn, Pham Hong Phong, Roan Thi Ngan · 2016
Motivated by Sanchez's approach for medical diagnosis and fuzzy linguistic approach, this paper introduces a novel medical diagnosis model based on linguistic representation. Analogous to Sanchez's notion of “Medical Knowledge” we define “Linguistic Medical Knowledge” as a fuzzy linguistic relation (FLR) from the set of symptoms to the set of diagnoses. In order to compose two FLRs, some fuzzy linguistic composition techniques are given: fuzzy linguistic max-min, fuzzy linguistic max-prod and fuzzy linguistic max-τ compositions. The rationality of the proposed method is examined in both theoretical and practical aspects.
