ConceptMix: Self-Service Analytical Data Integration Based on the Concept-Oriented Model

Abstract: Data integration as well as other data wrangling tasks account for a great deal of the difficulties in data analysis and frequently constitute the most tedious part of the overall analysis process. We describe a new system, ConceptMix, which radically simplifies analytical data integration for a broad range of non-IT users who do not possess deep knowledge in mathematics or statistics. ConceptMix relies on a novel unified data model, called the concept-oriented model (COM), which provides formal background for its functionality
