A diversity of interpretations for the concepts of the terms "information" and "knowledge" exists, implicating the ideas of information value and knowledge value, with their merely structural characteristics. This hinders the understanding and acceptance of new areas of study such as Knowledge Engineering and Management. Based on a review of some theoretical diversity and its criticism, this text proposes the inclusion and expansion of the term "cognition" as a necessary factor to differentiate between "information" and "knowledge", in the field of Knowledge Engineering and Management. Besides, some implications of this epistemological positioning are showed through a review in the processes of conversion of the knowledge, presented by Nonaka and Takeuchi (1997), and in the knowledge level modeling proposed by Allen Newell (1981)
