Despite advances in the requirements elicitation techniques, researchers show that even today software engineers cannot understand exactly what a product should offer to meet user needs and expectations. This paper aims to propose a new strategy to assist the process of requirements categorization, so that it becomes possible to extract from the user what he really expects of a product. The proposed framework is based on the concepts of requirements categorization established by Noriaki Kano, and on previous studies focused on collective intelligence, to propose different approaches to extract from the crowd the necessary knowledge to classify requirements and decide what should be prioritized and what should not, according to user expectations.
