Transformer-based Multi-task Learning for Disaster Tweet Categorisation

Understand

Social media has enabled people to circulate information in a timely fashion, thus motivating people to post messages seeking help during crisis situations.

• These messages can contribute to the situational awareness of emergency responders, who have a need for them to be categorised according to information types (i.e.
• the type of aid services the messages are requesting).
• We introduce a transformer-based multi-task learning (MTL) technique for classifying information types and estimating the priority of these messages.
