The paper presents an original fuzzy solution to the issue of outliers detection in graph databases. In particular, the following novelties are introduced: redefinition of an outlier in terms of fuzzy logic and methods for finding and marking outliers in graph-organized databases. The former refers to explaining outlying objects via fuzzy rules (IF-THEN rules) when linguistic knowledge rather than crisp data on that are accessible. The latter includes processing NOSQL graph-represented datasets to forms suitable for applying fuzzy rules. An application example on a Customer Relationship Management (CRM) with linguistic knowledge and graph structure is proposed.
