Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 325)


In this chapter, we focus on the status of Advanced Computing with Words (ACWW) and the challenges that it may encounter in the future. First, we elaborate on the notion of Computing with Words (CWW) and its various subareas. Then we present some non-engineering ACWW problems and connect them to more realistic engineering problems, after which we provide a roadmap for solving ACWW problems, and show how the Generalized Extension Principle (GEP) can be used to formulate their solutions. We also propose a syllogistic approach to solving ACWW problems that also uses the Extension Principle but in a different way. Finally, we discuss present and future challenges to ACWW, i.e. we explain what challenges ACWW encounters given the current trend of data abundance and widespread use of Internet for dealing with questions posed in natural languages.


Membership Function Soft Constraint World Knowledge Belief Structure Syllogistic Reasoning 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.



The authors would like to sincerely thank Prof. Lotfi A. Zadeh for his continuing support and enthusiasm, and for explanation of his solutions to ACWW problems to us. Mohammad Reza Rajati would like to acknowledge the generous support of the Annenberg Fellowship Program and the Summer Research Institute Program of the University of Southern California.
