# Dataset Introduction
## Overview
Question matching is a fundamental task in QA, which is generally considered a semantic matching task and sometimes a paraphrase recognition task. The goal of this task is to retrieve questions with similar intent to the input query from existing databases. We introduce a large-scale Chinese question matching corpus named LCQMC. Unlike paraphrase corpora, LCQMC is more general as it focuses on intent matching rather than paraphrase. The corpus contains 260,068 manually annotated question pairs, which are split into three subsets: a training set with 238,766 question pairs, a development set with 8,802 question pairs, and a test set with 12,500 question pairs. We evaluated several state-of-the-art sentence matching methods on this corpus. The experimental results not only verify the excellent quality of LCQMC but also provide reliable baseline performance for further research on this corpus.
