COMPUTING WITH WORDS BASED ON A HYBRID SEMANTIC-SYMBOLIC MODEL
Rosa M. Rodríguez, Macarena Espinilla, Luis M. Martínez, Jun Liu · 2009
The use of linguistic information based on the fuzzy linguistic approach to deal with uncertain and vague information it has been successfully used in many problems. It implies processes of computing with words (CW). The use of fuzzy numbers to accomplish the processes of CW provides accuracy and flexibility in the operations, but the results are fuzzy numbers that usually cannot be expressed linguistically. Hence symbolic approaches have been proposed to accomplish the processes of CW and improve the understanding of the results, but this has implied a lack of precision and a limitation of the operations in those processes. In this contribution, we present a hybrid linguistic computational model that carries out the operations by using fuzzy numbers, but the results are expressed linguistically in order to overcome the operational limitations and the lack of precision of symbolic approaches.
