Decomposing Generalization: Models of Generic, Habitual and Episodic Statements

Venkata Subrahmanyan Govindarajan, Benjamin Van Durme, Aaron Steven White

Abstract: We present a novel semantic framework for modeling linguistic expressions of generalization— generic, habitual, and episodic statements—as combinations of simple, real-valued referential properties of predicates and their arguments. We use this framework to construct a dataset covering the entirety of the Universal Dependencies English Web Treebank. We use this dataset to probe the efficacy of type-level and token-level information—including hand-engineered features and static (GloVe) and contextual (ELMo) word embeddings—for predicting expressions of generalization.
