Research on definition extraction has been conducted for well over a decade, largely with significant constraints on the type of definitions considered.In this work, we present DeftEval, a SemEval shared task in which participants must extract definitions from free text using a termdefinition pair corpus that reflects the complex reality of definitions in natural language.Definitions and glosses in free text often appear without explicit indicators, across sentences boundaries, or in an otherwise complex linguistic manner.DeftEval involved 3 distinct subtasks: 1) Sentence classification, 2) sequence labeling, and 3) relation extraction.
