Symptom rule pseudo code (A – B). This figure shows Symptom rule pseudo code. This rule is based on symptom keyword lists that contain only names of symptoms, The execution rule consists of matching the tokenized Document with largely used reference rule lists. The matching rule is what seeks the presence of each considered token and associates to that token in a keyword lists, and gives the name of the token to the same list, as shown in Figure 6A. The problem is when the token is present in more or no lists, in such cases grammatical rules and interpretation rules are necessary. An example of rule of such a case is shown in Figure 6B.
