## Tweets190: A Comprehensive Dataset of Crime-Related Tweets in Portuguese with Sentiment, Toxicity, and Location Information

This dataset contains 61.715 tweets related to possible crime reports, labeled with categories such as "Assalto", "Roubo", "Furto", "Assédio", "Segurança Pública", "Homicídio, and "Outros", along with sentiment analysis, toxicity analysis, and location identification.

A particular feature in the Portuguese language is that many words potentially related to crimes are used in non-criminal contexts, such as "O árbitro assaltou meu time ontem" (which translates to "The referee attacked my team yesterday" but in this case refers to something like a sports context, not an actual crime). Therefore, the dataset includes a KEYWORD column: if the keyword column is marked as 1 and the CRIME column is 0, this suggests the phrase may be ambiguous.

The dataset contains 5.000 tweets with actual crime reports, 5.000 with ambiguous expressions, and the remaining tweets are unrelated.

- **Sentiment Analysis 🙂**: The sentiment analysis was performed using PYsentimiento, which categorizes sentiments as Negative, Neutral, or Positive. More information can be found here: [Pysentimiento](https://pypi.org/project/pysentimiento/0.5.2rc3/)
- **Toxicity Analysis ☠️**: The toxicity analysis covers categories such as toxicity, severe toxicity, insult, profanity, threat, and identity attack, performed using the [Perspective API](https://perspectiveapi.com/).
- **Local ⛱️**: The entity recognition model is focused on identifying named entities, specifically locations mentioned in the tweets. The approach used for this can be found here: [Named Entity Recognition for Legal Domain](https://medium.com/@pierre_guillou/nlp-modelos-e-web-app-para-reconhecimento-de-entidade-nomeada-ner-no-dom%C3%ADnio-jur%C3%ADdico-b658db55edfb).

All tweets were preprocessed by removing special characters, converting to lowercase, and eliminating links.
