Actually this is to standardize the data. my project is to develop an Ebola diagnosis system using ANN, I have a set of raw data which contain it's symptom. the problem now is the ANN only will work with the numerical datatype.

Well, what are the measurement types? Ordinal, nominal, binary? You should have a consistent mapping from the source measurement type to integer (or float). Here is a basic explanation: https://www.kaggle.com/c/titanic/forums/t/4178/dealing-with-non-numeric-data
