Abstract: A data processing method includes: obtaining a to-be-detected text, and determining a context word set and a candidate substitute word set corresponding to a to-be-detected word in the to-be-detected text to be inputted into a pronoun resolution neural network for feature extraction; performing positive-example iteration processing and negative-example iteration processing on the features corresponding to the context word set and the candidate substitute word set, to obtain a positive-example feature vector length and a negative-example feature vector length, and calculating a substitute probability corresponding to each candidate substitute word in the candidate substitute word set according to the positive-example feature vector length and the negative-example feature vector length; determining a target substitute word according to the substitute probability corresponding to the each candidate substitute word; and inserting the target substitute word into the to-be-detected text according to a position corr

Abstract: Systems, methods and programmed products for using visual information in a video stream of a recording streaming teleconference among a plurality of participants to diarize speech, involving obtaining respective components of the teleconference including a respective audio component, a respective video component, respective teleconference metadata, and transcription data, parsing components into speech segments, tagging speech segments with source feeds, and diarizing the teleconference so as to label the speech segments based on neural network or heuristic analysis of visual information.
Abstract: A back-end server system for step-up authentication for conversational interfaces using spoken passphrases receive a conversational request for an action which requires step-up authorization; respond to the user through conversational artificial intelligence (AI) warning the user that an additional step is required; transmit, over a dedicated communication channel to the user and different than the conversational interface, a secret passphrase generated using a spoken passphrase dictionary; receive, by the conversational interface, a spoken submission from the user in response to the warning; confirm validity of the received spoken submission by comparing the spoken submission to the passphrase; and in response to confirmation of the spoken submission, authorize the requested action.
