1. A method of electronic chat production in an electronic discovery system, comprising:
receiving, by the electronic discovery system executing on a computer processor, an electronic chat comprising a set of electronic chat messages, each of the electronic chat messages having a timestamp;
determining a set of time gaps between the electronic chat messages in the set of electronic chat messages, the set of time gaps determined as respective time gaps between respective adjacent electronic chat messages in the set of electronic chat messages;
determining a set of models that model the set of time gaps, wherein determining the set of models comprises:
determining, using the set of time gaps, a Gaussian mixture model representing a mixture of Gaussian distributions;
selecting an optimum model from the set of models;
based on selecting the Gaussian mixture model as the optimum model and a text analysis of the electronic chat, performing an adaptive splitting of the set of electronic chat messages, comprising:
splitting the set of electronic chat messages into a set of conversations based on the Gaussian mixture model;
performing the text analysis on the set of conversations based on a chat subject matter identified in the set of electronic chat messages;
splitting the set of conversations based on the chat subject matter; and
storing the split set of conversations.
