# bixin [](https://travis-ci.org/bung87/bixin) [](https://pypi.python.org/pypi/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 ```python 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()`` ## Accuracy Test with 6226 taged corpus mixed up with shopping reviews 、Sina Weibo tweets 、hotel reviews 、news and financial news accuracy: **0.827771** **Notice**:neutral texts are all ignored. details about test dataset see wiki [关于测试数据集](https://github.com/bung87/bixin/wiki/%E5%85%B3%E4%BA%8E%E6%B5%8B%E8%AF%95%E6%95%B0%E6%8D%AE%E9%9B%86) ## Development ``> pip3 install -e ".[dev]" git+https://github.com/bung87/bixin`` ./dictionaries dictionaries from vary sources ./data processed dictionaries through ./scripts/tagger.py ./scripts/release_data.py release data to package ``./scripts/score.py`` all data archives: [https://github.com/bung87/bixin/releases/tag/v0.0.1](https://github.com/bung87/bixin/releases/tag/v0.0.1) run accuray testing with all .txt files under **test_data** directory sentence per line end with a space and a tag **n** or **p** ## Test `nosetests -c nose.cfg` for single python version `tox` for multiple python versions ## Acknowledgments bixin was inspired by [dongyuanxin](https://github.com/dongyuanxin/)'s [DictEmotionAlgorithm](https://github.com/dongyuanxin/various-codes/blob/master/DictEmotionAlgorithm/Main.py) ## License MIT © [bung](http://www.bungos.me)
