A method and an apparatus for detecting an abnormality of a caller are provided. The method includes at the beginning of a call, acquiring, by a terminal device, real voice/video data of a call object who needs abnormality detection and a corresponding pre-trained multi-stage neural network detection model, during the call, collecting, by the terminal device, call data according to a preset data collection policy, for each call object, inputting the currently collected call data and the real voice/video data of the call object into the model of the call object, and determining whether the call object is abnormal according to a detection result output by the model, in which the call data includes image data and/or voice data, and an identification manner adopted by the model includes face identification, voiceprint identification, limb movement identification, and/or lip language identification. By adopting the disclosure, the abnormality of the caller may be accurately detected, and the voice forgery and the video forgery mimicked by AI during a call may be accurately identified.

A syntactic analysis and hierarchical phrase model based machine translation system and method are provided. The machine translation system includes a word alignment module, a phrase extraction module, a gender syntactic annotation module, a syntactic based noncontiguous phrase abstract module, a noncontiguous phrase based translation module and an evaluation module. The machine translation system and method performs syntactic analysis based on a common contiguous phrase based machine translation model, and extracts a syntactic based noncontiguous phrase rule set from a bilingual aligned text, so as to address and issue of noncontiguous fixed custom in context of a whole sentence, and to comply with syntactic features of a language, translation is performed based on the noncontiguous phrase rule set and the phrase aligned table, and the translation results are evaluated based on the evaluation model, thereby improving the translation result.
