Introduction:

Question matching is a fundamental task of QA, which is usually recognized as a semantic matching task, sometimes a paraphrase identification task. The goal of the task is to search questions that have similar intent as the input question from an existing database. We introduce a large-scale Chinese question matching corpus (named LCQMC). LCQMC is more general than paraphrase corpus as it focuses on intent matching rather than paraphrase. The corpus contains 260,068 question pairs with manual annotation and we split it into three parts, i.e., a training set containing 238,766 question pairs, a development set with 8,802 question pairs, and a test set with 12,500 question pairs. We test several well-known sentence matching methods on it. The experimental results not only demonstrate the good quality of LCQMC, but also provide solid baseline performance for further researches on this corpus.
