Detection of employment status disclosures on Twitter

Model main characteristics:

• class: Lost Job (1), else (0)
• country: BR
• language: Portuguese
• architecture: BERT base

Model description

This model is a version of neuralmind/bert-base-portuguese-cased finetuned by @manueltonneau to recognize Portuguese tweets where a user mentions that she lost her job in the past month. It was trained on Portuguese tweets from users based in Brazil. The task is framed as a binary classification problem with:

• the positive class referring to tweets mentioning that a user recently lost her job (label=1)
• the negative class referring to all other tweets (label=0)

The dataset of Portuguese tweets on which this classifier was trained is open-sourced here. Details on the performance can be found in our ACL 2022 paper.
