Injecting Expert Knowledge and Corpus-Level Constraints in Natural Language Processing Models
Recent advances in data-driven machine learning techniques (e.g., deep neural networks) have revolutionized many natural language processing
applications. These approaches automatically learn how to make decisions based on the statistics and diagnostic information from large amounts of
labeled data. Despite these methods being successful in various applications, they run the risk of making nonsensical mistakes, suffering from domain shift, and reinforcing the societal biases (e.g. gender bias) that are present in the underlying data.  In this talk, I will describe a collection of results that leveraging corpus-level constraints and domain knowledge to facilitate the learning and
inference in Natural Language Processing applications. These results lead to greater control of NLP systems to be socially responsible and accountable.
