Chinese judges and prosecutors are using the latest information technology -- from big data and cloud computing to artificial intelligence -- to improve efficiency and accuracy. Big data services have helped judges search precedents, correct legal documents and analyze cases, said a report submitted by the Supreme People's Court (SPC) to the Standing Committee of the National People's Congress (NPC) on Wednesday at the bi-monthly legislative session. China launched a national database of legal documents and academic papers in March 2016, consisting of more than 20 million documents. Computing has also assisted prosecutors to screen evidence, refer to similar cases, research relevant laws, and draft legal documents, said another report submitted by the Supreme People's Procuratorate (SPP) at the same session. Speech recognition technologies have significantly saved trial time by turning recordings into formal transcripts.
