Abstract: The present invention provides a system and methods for extracting features from an object. The system comprises a receiver configured to receive an object comprising a set of instructions. Further, the system comprises an extraction module configured to extract one or more features of the object, wherein the one or more features comprise control-flow information, data-flow information, data-dependency information and control-dependency information. In an embodiment, the system includes an assessment module configured to assess at least one of functionality and quality of the first object, based on the features extracted and the grades corresponding to the second object.

Abstract: The system includes a receiving module configured to receive a first set of data and a second set of data, wherein the first set of data comprises one or more high quality objects, and one or more ungraded objects, wherein the second set of data comprises one or more ungraded objects, an identification module configured to identify the one or more high quality objects, an extraction module is configured to extract one or more features from each high quality object of the one or more high quality objects, a building module is configured to build a predictive model based on the one or more features extracted for the each high quality object, a comparison module configured to compares the one or more ungraded objects and the one or more high quality objects, and an assessment module configured to score the one or more ungraded objects.
