FCA Software Interoperability

www.upriss.org.uk Abstract. This paper discusses FCA software interoperability from a variety of angles: because the central FCA structures, formal contexts and concept lattices, can be represented in non-FCA software, interoperability with such software is of relevance. The non-FCA software in question is spreadsheet, relational database, graph and vector graphics software. The simplest approach to interoperability consists of providing file format conversion tools, such as FcaStone, which is therefore also discussed in this paper. Interoperability can be hindered by social factors, i.e. if the FCA researchers do not want to use non-FCA software. This issue is investigated with respect to software-derived graph layouts of lattice diagrams. An experiment that compares different software-derived lattice diagram layouts is conducted and leads to a surprising result. 1
