Questions/statements for Psychological Expert System

Hello, I am a computer science student in Indonesia.
Currently I am doing a paper about an expert system on psychological test based on Hippocrates Galenus typology with 4 types: Choleric, Melancholy, Phlegmatic, and Sanguine. Each type would be developed into 15 personality types namely Executive Pattern [Choleric-Sanguine (D-I)], Motivator Pattern [Choleric-Sanguine (D-I)], Director Pattern [Choleric-Phlegmatic (D-S)], Strategist Pattern [Choleric-Melancholy (D-C)], Negotiator Pattern [Sanguine-Choleric (I-D)], Marketer Pattern [Sanguine-Choleric (I-D)], Relater Pattern [Sanguine-Phlegmatic (I-S)], Performer Pattern [Sanguine-Melancholy (I-C)], inspector Pattern {Phlegmatic-Choleric (S-D)], Harmonizer Pattern [Phlegmatic-Sanguine (S-I)], Helper Pattern [Phlegmatic-Melancholy (S-C)], Trainer Pattern [Melancholy-Choleric (C-D)], Idealist Pattern [Melancholy-Phlegmatic-Choleric (C-S-D)], Diplomat Pattern [Melancholy-Sanguine (C-I)], Analyst Pattern [Melancholy-Phlegmatic (C-S)]. I have a good understanding on how to create the system, but I dont have the knowledge on the psychological part, specifically on the questions for the psychological test that is associated with the 4 mentioned types. Could anyone help on pointing out where I could get these information? It would also be a big help if someone could provide the sets of questions for the tests.

Thanks before.

NB : For those would like to help, I have prepared a questionnaire which could be found here: goo. gl/aGw3M
