The following project aims to implement a text classification pipeline for the Meetup events description.
Within the Meetup platform, every organized event needs to be manually tagged by the organizers to allow the platform's recommendation system to suggest the event to users based on their interests.
In this context, a system that suggests to organizers how to label their event based on how it was described by them would be a useful tool.
The text classification task is well known in literature and involves a series of operations and tricks, starting from the preprocessing of the texts up to the text representation.
Our goal was to find the best combination of preprocessing and text representation to be submitted to the best classifier, based on the classification performance, to maximize some performance evaluation metrics.
