Update to new features

I added three new features into the features set. They were entity_information_match, gender_match, and number_match. And the new test results were as follows:

类型 训练样例 测试样例 P R F

all 851468 283822 0.793076 0.693803 0.740126

The results displayed that the three new features were effective.
