+In this paper, we introduce Chinese AI and Law challenge dataset (CAIL2018),
+the first large-scale Chinese legal dataset for judgment prediction. CAIL contains more than 2.6 million
+criminal cases published by the Supreme People's Court of China, which are several times larger than other
+datasets in existing works on judgment prediction. Moreover, the annotations of judgment results are more
+detailed and rich. It consists of applicable law articles, charges, and prison terms, which are expected
+to be inferred according to the fact descriptions of cases. For comparison, we implement several conventional
+text classification baselines for judgment prediction and experimental results show that it is still a
+challenge for current models to predict the judgment results of legal cases, especially on prison terms.
+To help the researchers make improvements on legal judgment prediction.
