Sentiment analysis library for russian language

Project description

# Dostoevsky [![Build Status](](

<img align="right" src="">

Library for sentiment analysis of russian language

Currently, contains only one model: for classification of social networks comments / text messengers messages

## Install

Please note that `Dostoevsky` supports only Python 3.6 (3.7+ version'll be supported when tensorflow get it support, sorry)

$ pip install dostoevsky

## Social networks comment model

This model was trained on [RuSentiment dataset]( and achieves up to ~0.70 F1 score

### Usage

First of all, you'll need to download pretrained word embeddings and model:

$ python -m download vk-embeddings cnn-social-network-model

Then, we can build our pipeline: `text -> tokenizer -> word embeddings -> CNN`

from dostoevsky.tokenization import UDBaselineTokenizer
from dostoevsky.word_vectors import SocialNetworkWordVectores
from dostoevsky.models import SocialNetworkModel

tokenizer = UDBaselineTokenizer()
tokens = tokenizer.split('всё очень плохо') # [('всё', 'ADJ'), ('очень', 'ADV'), ('плохо', 'ADV')]

word_vectors_container = SocialNetworkWordVectores()

vectors = word_vectors_container.get_word_vectors(tokens)
vectors.shape # (3, 300) - three words/vectors with dim=300

model = SocialNetworkModel(

model.predict(['наступили на ногу', 'всё суперски']) # array(['negative', 'positive'], dtype='<U8')
