In this paper, we show how the existence of taxonomies on objects and/or attributes can be used in formal concept analysis to help discover generalized patterns in the form of concepts. To that end, we analyze three generalization cases and different scenarios of a simultaneous generalization on both objects and attributes. We also contrast the number of generalized patterns against the number ...

We present an application of formal concept analysis aimed at creating and representing a meaningful structure of knowledge communities under the form of a lattice-based taxonomy built upon groups of agents jointly manipulating some notions. The resulting structure is however usually extremely complex, hence uneasy to comprehend. We consider two approaches to build a concise representation resp...

A logical formalism associating properties to space parcels in so-called attribute formulas, is proposed. Properties are related through the axioms of a taxonomy graph, and parcels through a partonomy graph. Attributive formulas establish relations between parcels and properties, and we use them to align different taxonomies, over a compatible partonomy, using Formal Concept Analysis. We discus...

Categories are often organized into hierarchical taxonomies, that is, tree structures where each node represents a labeled category, and a node’s parent and children are, respectively, the category’s supertype and subtypes. A natural question is whether it is possible to reconstruct category taxonomies in cases where we are not given explicit information about how categories are related to each...

Because botanical taxonomies are prototypical classifications it would seem that it should be easy to formalize them as concept lattices or type hierarchies. On closer inspection, however, one discovers that such a formalization is quite challenging to obtain. First, botanical taxonomies consist of several interrelated hierarchies, such as a specimen-based plant typology, a name hierarchy and a...

The identification of parasites in tissue sections is often difficult and fresh specimens are always required for accurate taxonomical classification. However, histological sections are in many cases the only material available and the identification of parasites in sections the subject of the recent histopathology workshop held in Dublin. The group reviewed the characteristics of representativ...
