As part of the AI2 Project Aristo, we are developing a question answering system that can recognize instances of processes. We are designing a system that can automatically identify the key semantic roles and use them in an alignment framework to answer questions. Project involves extending state-of-the-art techniques in NLP and Machine learning.
