## tweetSentBR (Few-shot)

This dataset is a subset of the [tweetSentBR](https://bitbucket.org/HBrum/tweetsentbr), it contains only 75 samples from the training set and all 2.000+ instances of the test set.  
This is meant for evaluating language models in a few-shot setting on the [🚀 Open Portuguese LLM Leaderboard](https://huggingface.co/spaces/eduagarcia/open_pt_llm_leaderboard) with the [portuguese fork](https://github.com/eduagarcia/lm-evaluation-harness-pt) of the Eleuther AI Language Model Evaluation Harness

For the complete dataset with 15.000+ annotated tweets go to https://bitbucket.org/HBrum/tweetsentbr or contact the paper authors: http://www.lrec-conf.org/proceedings/lrec2018/summaries/389.html

### Description

TweetSentBR is a corpus of Tweets in Brazilian Portuguese. It was labeled by several annotators following steps stablished on the literature for improving reliability on the task of Sentiment Analysis.
Each Tweet was annotated in one of the three following classes:

* Positive - tweets where a user meant a positive reaction or evaluation about the main topic on the post;

* Negative - tweets where a user meant a negative reaction or evaluation about the main topic on the post;

* Neutral - tweets not belonging to any of the last classes, usually not making a point, out of topic, irrelevant, confusing or containing only objective data.
