NewsSentiment: easy-to-use, high-quality target-dependent sentiment classification for news articles

NewsSentiment is an easy-to-use Python library that achieves state-of-the-art performance for target-dependent sentiment classification on news articles. NewsSentiment uses the currently best performing targeted sentiment classifier for news articles. In contrast to regular sentiment classification, targeted sentiment classification allows you to provide a target in a sentence. Only for this target, the sentiment is then predicted. This is more reliable in many cases, as demonstrated by the following simplistic example: "I like Bert, but I hate Robert."

We designed NewsSentiment to serve as an easy-to-use wrapper around the sophisticated GRU-TSC model, which was trained on the NewsMTSC dataset consisting of more than 10k labeled sentences sampled from political news articles. More information on the dataset and the model can be found here. The dataset, the model, and its source code can be viewed in our GitHub repository.

Installation

It's super easy, we promise!

You just need a Python 3.7 or Python 3.8 environment. See here if you don't have Python or a different version (run python --version in a terminal to see your version). Then run:

pip3 install NewsSentiment        # without cuda support (choose this if you don't know what cuda is)
pip3 install NewsSentiment[cuda]  # with cuda support

You're all set now :-)

Target-dependent Sentiment Classification

Note that using NewsSentiment the first time will take a few minutes because it needs to download the fine-tuned language model. Please do not abort this initial download. Since this is a one-time process, future use of NewsSentiment will be much faster.

from NewsSentiment import TargetSentimentClassifier
tsc = TargetSentimentClassifier()

sentiment = tsc.infer_from_text("I like " ,"Peter", " but I don't like Robert.")
print(sentiment[0])

sentiment = tsc.infer_from_text("" ,"Mark Meadows", "'s coverup of Trump’s coup attempt is falling apart.")
print(sentiment[0])
