Abstract
A method and system for classifying text data in a document based on hierarchy classification is disclosed. A plurality of line regions comprising text data in the document are determined. Positional information and text-characteristic information for each of the plurality of the line regions is determined. For each of the plurality of line regions, a first hierarchy classification from the plurality of hierarchy classifications based on a plurality of predefined rules is determined and a second hierarchy classification from the plurality of hierarchy classifications and a respective probability value based on a machine learning technique is determined. Each of the plurality of line regions are classified based on the first hierarchy classification or the second hierarchy classification. The second hierarchy classification is selected in case the respective probability value of the second hierarchy classification is greater than equal to a predefined threshold.
