Eur Symposium on Computer Intelligence and Mathematics (ESCIM), May 10-14 2026, Timișoara, Romania


We participated with a communication on the development of a package aimed at the application of Formal Concept Analysis, implemented in the R programming language. The title of the communication was Interactive Fuzzy FCA Recommender System: A Visual Approach using fcaR.

Traditional recommender systems often operate as black boxes, making them difficult to integrate into critical domains such as medical diagnosis,
where explainability is mandatory. This paper introduces an interactive recommendation framework based on the navigation of Fuzzy Formal Concept Lattices. Rather than relying on offline calculations or static rule sets, our approach implements a Guided Recommender Algorithm that allows experts to explore the knowledge structure iteratively. By applying a Local Zoom Strategy, the system extracts relevant sublattices in real-time, enabling users to refine searches through attributes with fuzzy degrees of certainty.

In addition, Manuel Ojeda-Hernández participated in the organization of a Special Session on
Recent trends in knowledge representation and modelling, together with co-organizers David Lobo and Roberto G. Aragón.
