How does a Pre-Trained Transformer Integrate Contextual Keywords? Application to Humanitarian Computing
It is possible to integrate textual metadata into transformers in order to help the model improve its performances. We show the model uses the semantics of the keyword metadata analyzing the attention interaction between the metadata and the text to classify. We applied this to a humanitarian classification task over tweets, using the disaster event type as context, and finally show this method is also useful to caracterize a new event like a hurricane in a data-driven way.

Improving Sentiment Analysis over non-English Tweets using Multilingual Transformers and Automatic Translation for Data-Augmentation
We propose a technique to leverage machine translation for multilingual sentiment analysis. Appart from English, which has better models and more ressources, it is useful to translate all the tweets from every language to all the other languages and train a multilingual model over this new augmented dataset.
