1. A method for digitization of a document, the method comprising: scanning, by one or more processors, the document to generate an electronic document; segmenting, by the one or more processors, the electronic document into one or more portions; selecting, by the one or more processors, a first set of portions from the one or more portions of the electronic document based on at least a quality score associated with each of the one or more portions, wherein the quality score is assigned to each of the one or more portions based on a presence of pre-defined markings in the one or more portions and a presence of content in each of the one or more portions, and wherein the quality score is indicative of the quality of scanning of the one or more portions; identifying, by the one or more processors, one or more characters in the first set of portions of the electronic document based on a character recognition technique; classifying, by the one or more processors, each portion in the first set of portions in one or more groups based on at least a status of identification that indicates a quality of the one or more characters identified using the character recognition technique; creating, by the one or more processors, one or more tasks for each of the one or more groups, wherein a type of the one or more tasks created for a group of the one or more groups corresponds to the quality of the one or more characters and is different from the type of the one or more tasks created for other group of the one or more groups, wherein each type of the one or more tasks is associated with a cost, and wherein the cost of one type of the one or more tasks is different from the cost of other type of the one or more tasks; transmitting, by the one or more processors, the one or more tasks to one or more crowdworkers based at least on the respective type of the one or more tasks; receiving, by the one or more processors, a response for each of the one or more tasks from each of the one or more crowdworkers; and generating, by the one or more processors, a digitized electronic document based on the response received for each of the one or more tasks.
