As to human-centered intelligent information services, many innovative technologies have been studied. For example, a novel model called TSQA is developed for temporal reasoning, which uses reasoning based on a time-aware temporal knowledge graph to anticipate timestamp information in natural language. The OPERA model is designed for numerical reasoning to predict lightweight discrete operators that may then be softly executed to get an answer, improving numerical reasoning and interpretability. Additionally, the SAE approach is suggested for multi-hop reasoning, which allows for precise evidence (documents/sentences) selection as well as genuine logical linkages concatenated in multiple documents for reasoning. Jingdong has developed intelligent legal platforms such as "Jingdong Dongdong" intelligent law robots and Jingdong intelligent customer service as a result of these efforts. In addition, a number of intelligent applications for courts have been offered using AI technology, including indoor file delivery robots lessening the workload of case managers, facial recognition smart gates serving as assistants for self-service registration and diversion, various business enabling the general public to handle the whole process of litigation without having to leave their homes, and virtual reality panorama litigation service halls.
