Development of a Cognitive Assistant to Learn Concepts for Placement Assistance

A cognitive assistant helps the humans and enhance their capabilities to solve a large range of complex tasks. The main aim of this paper is to develop a pedagogical cognitive assistant to improve the reasoning abilities and decision making skills. The proposed system has been implemented to assist as a personal agent for students to learn python programming language. The cognitive assistant facilitates natural interactions with the students and it applies human reasoning skills to judge the students ability and train them further. The proposed techniques include Question Answer (QA) analyser, dynamic study plan generation by using assertion graph and accurate answer generation by using evidence extraction and inference generation. A cognitive conversation increases user’s satisfaction and easily engages them with the system and it has achieved significant higher learning gains than a non-interactive online course. The proposed system is evaluated by using the confidence weighted score evaluation metric.
