Abstract
The eighteen papers in this special section focus on emerging techniques and applications supported by fuzzy logic and artificial intelligence (AI). AI has become the focus of the day and attracted much attention from researchers, industries, and governments. This special issue serves as a forum to bring together all emerging techniques for fuzzy logic and fuzzy set-based AI and foster new advancements along this important direction. Actually, there have been a number of research pursuits that position themselves at the junction of AI and fuzzy logic. For example, natural language processing, viewed as the jewel in the crown of AI, has been one of the focal points in the domain of fuzzy logic and fuzzy sets. Fuzzy sets can offer an effective paradigm supporting accurate understanding of natural language and build efficient linkages to human intelligence through concepts and computing with membership functions, in particular type-2 fuzzy sets for explainable AI.
