A Definitional Sentence Extraction Task is an information extraction task that can solve a definition creation task given a text corpus.
- Context:
- It can range from being a Human-Performed Definitional Sentence Extraction Task to being an Automated Definitional Sentence Extraction Task (solved by a definitional sentence extraction system).
- It can be supported by a Definitional Sentence Classification Task and/or a Definitional Sentence Retrieval Task.

- QUOTE: Definition extraction has been a popular topic in NLP research for well more than a decade, but has been historically limited to well-defined, structured, and narrow conditions. In reality, natural language is messy, and messy data requires both complex solutions and data that reflects that reality. In this paper, we present a robust English corpus and annotation schema that allows us to explore the less straightforward examples of term-definition structures in free and semi-structured text. …
