While natural language processing (NLP) has experienced enormous progress in recent years, some tasks remain incredibly challenging. Namely, Coreference Resolution is a fundamental, unsolved task that attempts to resolve which words in a body of a text all refer to the same underlying "thing" (e.g., entity or event). This serves as an essential component of many other core NLP tasks, including information extraction, question-answering, document summarization, etc. However, decades of research have primarily focused on resolving entities (e.g., people, locations, organizations), with significantly less attention given to events -- the actions performed. In our work, we developed a state-of-the-art model for event coreference that uses almost no features. Last, we touch on remaining challenges and future directions.
