This paper is a tutorial on Formal Concept Analysis (FCA) and its applications. FCA is an
applied branch of Lattice Theory, a mathematical discipline which enables formalisation of …

Abstract Relational Concept Analysis (RCA) has been designed to classify sets of objects
described by attributes and relations between these objects. This is achieved by iterating on …

Multimodal clustering is an unsupervised technique for mining interesting patterns in n-adic
binary relations or n-mode networks. Among different types of such generalised patterns one …

The recommender systems are used to mainly suggest recommendations to the online users
by utilizing the user preferences recorded during the item purchase. No matter how, the …

This paper introduces several recommender methods for crowdsourcing platforms. These
methods are based on modern data analysis approaches for object-attribute data, such as …

De nombreuses approches ont été élaborées pour extraire des connaissances à partir des
données. On distingue traditionnellement l'analyse descriptive et l'analyse prédictive. Nous …

In this paper, we explain how Galois connection and related operators between sets of users
and items naturally arise in user-item data for forming neighbourhoods of a target user or …

This paper focuses on item recommendation for visitors in a museum within the framework of
European Project CrossCult about cultural heritage. We present a theoretical research work …

One of the first models ever to be considered as an index for documents using terms as
