The dataset and implementation of Prescription Topic Model in our paper:

Liang Yao, Yin Zhang, Baogang Wei, Wenjin Zhang, Zhe Jin. (2018). "A Topic Modeling Approach for Traditional Chinese Medicine Prescriptions". IEEE Transactions on Knowledge and Data Engineering (TKDE) 30(6), pp.1007-1021.

Data

98,334 raw prescriptions with herbs and symptoms are in /data/prescriptions.txt . Each line is for a prescription, symptoms are on the left and herbs are on the right.

The preprocessed 33,765 prescriptions: /data/pre_herbs.txt, /data/pre_symptoms.txt.

Training set: /data/pre_herbs_train.txt, /data/pre_symptoms_train.txt

Test set: /data/pre_herbs_test.txt, /data/pre_symptoms_test.txt

(Note: Each line in above files is for a prescription. Each number in above files means an herb or a symptom, each number is an index of the following herb list or symptom list. For example, '5' in /file/pre_herbs_train.txt means the 6th herb in the herb list /data/herbs_contains.txt, '17' in /file/pre_symptoms_train.txt means the 18th symptom in the symptom list /data/symptom_contains.txt. )

Herb list: /data/herbs_contains.txt

Symptom list: /data/symptom_contains.txt

TCM MeSH herb-symptom correspondence knowledge: /data/symptom_herb_tcm_mesh.txt

Symptom Category: /data/symptom_category.txt
