1. A method for analyzing a plurality of documents, comprising: receiving the plurality of documents via a computing device; receiving user input from the computing device, the user input including hard coding of a subset of the plurality of documents, the hard coding based on an identified subject or category; and executing instructions stored in memory, wherein execution of the instructions by a processor: generates an initial control set based on the subset of the plurality of documents and the received user input on the subset, analyzes 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, analyzes the first portion of the plurality of documents by applying an adaptive identification cycle, the adaptive identification cycle being based on the initial control set, user validation of the automated coding of the first portion of the plurality of documents and confidence threshold validation, and retrieves a second portion of the plurality of documents based on a result of the application of the adaptive identification cycle on the first portion of the plurality of documents.
