1. Data-processing device ( 1 ) characterized in that it comprises in combination: a memory ( 10 ) organized on the one hand, into two spaces, one containing attributes describing the stored data, and the other containing connexity links among the stored data, and, on the other hand, according to one or more dimensions respectively associated with attributes and divided into one or more hierarchized segments, the data being inputted by creating, deleting or modifying the values of attributes characterizing said segments; means ( 11 ) for integrating one or more incoming information streams which analyze said streams to determine the data constituting same and to structure said data and the attributes thereof according to the organization of said memory ( 10 ); an inference engine ( 14 ) implementing, in parallel or in series, inference rules ( 141 ) grouped together in libraries ( 15 ), said rules ( 141 ) being programmed to regenerate a sequence including at least one segment of the memory, by creating, deleting or modifying at least one datum and/or at least one attribute value and/or at least one connexity link during the implementation thereof in the at least one space of the memory, means ( 13 ) for allocating resources activating or deactivating the inference rules ( 141 ) on the basis of a priority rule, means ( 12 ) for extracting data, which are identified by programming and/or by at least one selected attribute value and/or at least one selected connexity link; and/or which are located in one or more selected segments of the memory ( 10 ), and providing same in one or more outgoing information streams.
