1. A method for analyzing a plurality of documents, comprising: receiving the plurality of documents via a computing device; filtering the plurality of documents to produce a subset of the plurality of documents; executing instructions stored in memory, wherein execution of the instructions by a processor generates an initial control set based on random sampling of the subset of the plurality of documents; receiving user input from the computing device, the user input based on an identified subject or category; and executing instructions stored in memory, wherein execution of the instructions by a processor: reviews the initial control set to determine at least one seed set parameter associated with the identified subject or category, automatically codes a first portion of the plurality of documents, based on the initial control set and the at least one seed set parameter associated with the identified subject or category, automatically codes a second portion of the plurality of documents resulting from an application of user analysis and an adaptive identification cycle, and adds the coded second portion of the plurality of documents to the initial control set.
