Recent Interfaces for Formal Concept Analysis

Our test data are composed of three lists of genes corresponding to the so-called “Cancer Module 1” (Ovary Genes), “Cancer Module 2” (Dorsal Root Ganglia Genes), and “Cancer

A recent exam- ple is of the Broad Institute where biological data were gathered from multiple resources to get thousands of predefined gene sets stored in the Molecular Signa-

Indeed, under the restriction to BCNF, the original form of ids introduced by Calvanese, De Giacomo, and Lenzerini [9] is expressive enough to transfer FDs from the relational schema

Remember that in the crisp setting the exact same semantics are used to compute the derivation of a set of attributes or the interpretation of a conjunction of concept names.. This

Our test data are composed of three lists of genes corresponding to the so-called “Cancer Module 1” (Ovary Genes), “Cancer Module 2” (Dorsal Root Ganglia Genes), and “Cancer

However the situation is dual to the classical one: in our case test examples correspond to fixed subsets and probabilistically generated formal concepts must fall into selected

Some of the younger researchers in the field were not even born when Rudolf Wille’s seminal paper “Restructuring lattice theory: an ap- proach based on hierarchies of concepts”
