Knowledge discovery in databases (KDD) is a process for extracting from large databases knowledge units that can be interpreted and reused within knowledge-based sys- tems. From an operational point of view, this process is based on three main steps: (i) selection and preparation of the data, (ii) data mining, (iii) interpretation of the extracted units. The KDD process – -as implemented in the Orpailleur team– is based on data mining methods that are either symbolic or numerical. Symbolic methods are based on frequent itemsets search, association rule extraction, For- mal Concept Analysis (FCA[GW99]), and extensions of FCA such as Relational Concept Analysis (RCA [?]) and Pattern Structures [?]. Numerical methods are based on second-order Hidden Markov Models (HMM[MB06]), which have good capabilities for locating “stationary segments” in data and are thus well adapted to the mining of temporal and spatial data.
