Natural language processing (NLP) is transforming the way humans communicate with each other and with machines, with applications in multi-document summarization, machine translation, question answering, fact checking, decision support in health domains, or any applications which require making decisions that involve complex reasoning or entail combining different modalities (e.g., vision and text). The goal of the workshop, as well as of the entire program, is to facilitate collaboration among NLP researchers and to encourage closer interactions between the NLP and Machine Learning communities.
