重构论文A Biterm Topic Model for Short Texts提供的源代码，编译成一个python 扩展模块
编译：
make
如果是windows平台，需要小修改
安装:
python setup.py install
使用 demo:
from biterm.Model import bitermModel as model
mymodel=Model(20,99509,2.5,0.01,5,101) #topic、voc size、alpha、belta、savestep、iteration
mymodel.train("data/data.txt")
relist=mymodel.predict([232,435,56,76,890]) #words indexs
mymodel.savemodel("save/")
del mymodel
mymodel=Model(20,99509,2.5,0.01,5,101)
mymodel.loadmodel("save/")
relist=mymodel.predict([232,435,56,76,890])
