Challenges of computing with words in decision making


Online lecture with Dr. Rosa Rodriguez: Challenges of computing with words in decision making The concept of computing usually implies calculation processes either by mathematical means of numbers and symbols or by a computer. Computing processes done by humans employ mostly words in computing and reasoning, arriving at results linguistically expressed from linguistic premises. Computing with words applies the same view to their computing processes aiming at obtaining linguistic outcomes from linguistic inputs. Because words have fuzzy denotations when they are used by human beings, the paradigm of Computing with Words (CW) is a branch of Zadeh’s fuzzy logic. Decision makers are expected to assess numerically their preferences. The complexity of decision problems implies uncertainty that can be modelled using linguistic information, mainly based on fuzzy based linguistic approaches. However, these approaches only allow the elicitation of simple assessments composed by either one label or a modifier with a label. The necessity of more complex linguistic expressions to interpret decision makers’ knowledge has led to extensions of classical approaches that allow the construction of expressions and elicitation of preferences in a way closer to human cognitive processes. This talk will provide an overview of the broadest fuzzy linguistic approaches used for CW in decision making and some challenges that future proposals should achieve to improve complex linguistic modelling in decision making.
