Next Priority Concept: A new and generic algorithm computing concepts from complex and heterogeneous data

Autor: Demko, Christophe, Bertet, Karell, Faucher, Cyril, Viaud, Jean-François, Kuznetsov, Sergeï

In this article, we present a new data type agnostic algorithm calculating a concept lattice from heterogeneous and complex data. Our NextPriorityConcept algorithm is first introduced and proved in the binary case as an extension of Bordat's algorith

The rising number of different kinds of data that can be used to describe a human trajectory (Such as GPS Coordinate, GSM, RFID, RSSI...) put in the spotlight the semantically rich trajectory. A semantic trajectory annotates semantic knowledge direct
