This paper describes a methodology to detect the emergence (or the disappearance) of concepts through the observation of natural language communications (NLC). NLC are the documents, e-mails, written communications of any kind, that the members of a web community produce, access, and exchange for their purposes. The emergence of a new concept is suggested by the repetitive and consistent use of certain terms, while its intended meaning and appropriate conceptualization is obtained through a combination of text mining and algebraic methods.
