planets

This dataset records some properties of the planets in our solar system.

Provides tools to perform fuzzy formal concept
analysis, presented in Wille (1982) <doi:10.1007/978-3-642-01815-2_23>
and in Ganter and Obiedkov (2016) <doi:10.1007/978-3-662-49291-8>. It
provides functions to load and save a formal context, extract its
concept lattice and implications. In addition, one can use the
implications to compute semantic closures of fuzzy sets and, thus,
build recommendation systems.
