Description:

The hardest part of building a text classifier is finding labelled data to train the model. The next hardest part is making sure that data is fair and representative. In this talk we will discuss some approaches to rapidly generating corpora suitable for supervised training from public data and with open-source tools.

This talk will include some practical tips as well as some less-obvious pitfalls, and is suitable for both novices and more experienced Natural Language Processing Practitioners.

At the end of the talk you will be able to give a convincing answer to the eternal question: How do I build a text classifier for a product that doesn't exist yet?

Co-presented with Alex O'Connor
