bixin

Chinese Sentiment Analysis base on dictionary and rules.

CHANGELOG

prior to v0.0.4, bixin depends on cppjieba-py, which requires a c++ 11 compillation makes hard to use, I decided to use jieba_fast.

it will solve the following problems:

• hard to install the dependency cppjieba-py
• can't load user dictionary
• word segment difference from jieba

but it slower than use cppjieba-py

Installation

> pip3 install bixin

Usage

    from bixin import predict
    text ="幸福每时每刻都会像路边的乞丐一样出现在你面前。要是你觉得你所梦想的幸福不是这样的，因而断言你的幸福已死亡，你只接受符合你的原则和心愿的幸福，那么你就会落得不幸。"
    # 出自安德烈·纪德《人间食粮》
    predict(text)
    # sentiment score: 0.42

sentiment score is in the range of -1 to 1

predict will load dictionary data at first time,to load it manually use predict.classifier.initialize()
