Welcome to the world of sentiment analysis with Dostoevsky! This library is designed to analyze the sentiment of Russian text efficiently. Whether you’re a novice or a seasoned programmer, this guide will help you get started with resolution and ease. Let’s delve into the simplicity of implementation while addressing potential hurdles you may encounter along the way.

Installation

Before we begin, it’s important to note that Dostoevsky supports Python versions 3.7 and above on both Linux and Windows platforms.

bash
$ pip install dostoevsky

Getting Started with the Social Network Model: FastText

The core of Dostoevsky’s functionality lies in its models. The Social Network model, which is trained using the RuSentiment dataset, achieves an impressive F1 score of approximately 0.71.

Setting Up the Environment

First, you’ll need to download the binary model:

bash
$ python -m dostoevsky download fasttext-social-network-model

Using the Sentiment Analyzer

Think of the sentiment analysis process as if you’re hiring a chef to evaluate the taste of various dishes. Each dish represents a message, and the chef (our model) will give feedback on its flavor (sentiment). Here’s how you set it up:

python
from dostoevsky.tokenization import RegexTokenizer
from dostoevsky.models import FastTextSocialNetworkModel

# Create a tokenizer to break down the sentences into analyzable components
tokenizer = RegexTokenizer()
tokens = tokenizer.split('всё очень плохо')  # The tokenizer splits the message into tokens.

# Initialize the model using our tokenizer
model = FastTextSocialNetworkModel(tokenizer=tokenizer)

# Define a list of messages for sentiment analysis
messages = [
    'привет',  # Hello
    'я люблю тебя!!',  # I love you!!
    'малолетние дебилы'  # Idiotic teens
]

# Get predictions for the given messages
results = model.predict(messages, k=2)

# Output the results
for message, sentiment in zip(messages, results):
    print(message, '-', sentiment)

In this code, we have created a tokenizer, defined messages to analyze, and printed the corresponding sentiment for each message. This structure allows for flexible testing of diverse inputs.

Troubleshooting Common Issues

• Python Version Issues: Make sure you are using Python 3.7 or above. Check your version using python --version.
• Installation Problems: If you encounter an error during installation, ensure that pip is up to date by running pip install --upgrade pip.
• Model Download Failures: Verify your internet connection, and try running the download command again.
• Tokenization Errors: Ensure the input text is correctly formatted and uses the right encoding.
