Abstract: One of the main restrictions of the relational data model is the lack of support for flexible, imprecise and vague information in data encoding and retrieval. Fuzzy set theory and more specifically intuitionistic fuzzy sets provides an effective solution to model the data imprecision in relational databases. Several works in the last 30 years have used fuzzy set theory to extend relational data model to permit representation and retrieval of imprecise data. However, to the best of our knowledge, such approaches have not been designed to scale-up to very large datasets. In this paper, we develop MapReduce algorithms to enhance the standard relational operations with IFS predicates.
