Unified External Data Access Implementation in Formal Concept Analysis Research Toolbox
Formal Concept Analysis (FCA) provides mathematical models, methods and algorithms for data analysis. However, by now there is no easily available program system, which would provide data analyst with unified, intelligible and transparent access to various external data sources with large amount of heterogeneous data for subsequent FCA-based knowledge discovery. The lack of such tools complicates spreading FCA methods among big data analysts and miners of unstructured data. In this paper, we describe advances and new functionality in external data querying and preprocessing subsystems of Formal Concept Analysis Research Toolbox (FCART), which helps processing data of different types in a unified way.
