Knowledge acquisition at the time of Big Data

What is exactly `Big Data', and for what purpose and application is it really efficient? Between the commercial promises made by the industrial actors and the Cassandra's cautions from some whistle-blowers, we propose a singular Big Data field to investigate with Inductive Data-Driven Algorithms: developing collections. Last but not least, we investigate the innovative possibility to curate `figural' collections, characterized by Jean Piaget as follows: “A figural collection composes a figure, through the spatial relationships between its elements, whereas non-figural collections and classes are free of any figure”. Thus, we incidentally disclose some important Abstract Truth of Big Data.
