Appointment Information Call System and its Method Reflecting Constraints

摘要

The present invention relates to a system for calling appointment information during a call reflecting constraints, comprising: a recording module for recording, storing and managing a conversation during a call; an appointment term sensing module extracting preset appointment terms from the conversation, and determining the appointment terms by determining that the conversation includes an appointment when the sum of weights of the extracted appointment terms exceeds a reference value; Conversations containing confirmed appointment terms and m conversations pre-stored in the call recording DB are indexed, time zones corresponding to preset appointment discovery rules are extracted from conversations during a call and indexed conversations, and object name recognition ( an appointment information extraction module for generating appointment information by extracting a place that meets a constraint through NER); an appointment time search module for recalculating the travel time according to constraints including the appointment subject, place, and time zone, and arranging time zones matched with the appointment information in time series according to the overlapping time zone calculation rule; and an appointment output module that converts the appointment information into voice and outputs it according to the sorted time zone.
