Natural language processing (NLP), or the task of turning human language into structured data for machines to understand, powers the chatbots, voice assistants, predictive text, and other pervasive language applications that make our lives easier. We feel open-source tools complement the rapidly evolving field of NLP by helping to drive innovation through collaboration. In this breakout session, participants will be invited to share their experiences and lessons learned using open-source tools for NLP and explore how open-source tools may be able to help with current challenges in NLP.
