Established at the end of 2015, with 45 employees our QA system uses deep learning engines such as NLU(Natural Language Understanding), MRC(Machine Reading Comprehension) and Paraphrasing engines to help optimize workflows with data-intensive companies by our 1)Data Intelligence for business service. Our system can also be applied to 2)AI-based chatbots and 3)Smart devices.
