Sentence Retrieval is the task of retrieving a relevant sentence in response to a query, a question, or a reference sentence. Tasks such as question answering, summarization, novelty detection, and information provenance make use of a sentence-retrieval module as a preprocessing step. The performance of these systems is dependent on the quality of the sentence-retrieval module. Other tasks such as information extraction and machine translation operate on sentences, either using them as training data, or as the unit of input or output (or both), and may benefit from sentence retrieval to build a training corpus, or as a post-processing step.
