multi_language_sentiment 0.1.0

Sentiment analysis pipeline for texts in multiple languages.

multi-language-sentiment

A pipeline for sentiment analysis for texts with unknown language.

We use the lingua-language-detector to detect the language and run the text samples through an sentiment analysis appropriate pipeline for that language.

Usage

Basic usage for analysing a list of sentences:

import multi_language_sentiment

texts = ["This is a positive sentence", "Tämä on ikävä juttu"]
sentiments = multi_language_sentiment.sentiment(texts)
print(sentiments)

This should print

[{'label': 'positive', 'score': 0.89024418592453}, {'label': 'negative', 'score': 0.8899219632148743}]

Supported language

The module currently supports the following langauges by default: English, Japanese, Arabic, German, Spanish, French, Chinese, Indonesian, Hindi, Italian, Malay, Portuguese, Swedish, and Finnish.

For other languages, you must supply a path for a HuggingFace sentiment analysis pipeline. To supply a pipelien for a new language, use the models parameter:

import multi_language_sentiment
from lingua import Language

texts = ["This is a positive sentence", "Tämä on ikävä juttu"]
models = {Language.FINNISH: "fergusq/finbert-finnsentiment"}
sentiments = multi_language_sentiment.sentiment(texts, models = models)

Technical details

Note that the pipeline will split each text sample to a maximum length of 512 characters. The sentiments are aggregated by adding up the scores and taking the largest value.
