摘要

A system and method for extracting data values from a conversation to complete an electronic trade ticket over a communications network. The system comprises a plurality of client devices and a processor based server. A digital switchboard routes an incoming call from a first user to a second user to the server over the communications network. The telephone numbers of the users are verified against the stored telephone numbers in a database. A sample representing a predetermined period of the recorded conversation are utilized to identify the users. The conversation between the users are transcribed onto an electronic text file and processed to extract terms to populate data fields of an electronic trade ticket.

1. A computer based method for extracting data values from a conversation to complete an electronic trade ticket over a communications network, comprising the steps of:
recording a conversation between first and second users by a recorder of a server and storing the conversation in a database; obtaining a sample representing a predetermined period of the conversation by a speaker engine of the server to identify and verify the first and second users; transcribing the conversation to an electronic text file by a speech recognition engine of the server and storing the electronic text file in the database; performing natural language processing on the electronic text file by a natural language processing engine of the server to correct typographical, syntax and form errors, and to obtain trade information through relational co-reference and entity tracking; and generating an electronic trade ticket by extracting terms from the electronic text file processed by the natural language processing engine to populate data fields of the electronic trade ticket based on the obtained trade information by a ticket generator of the server.
