'Data Mining Patterns' gives an overall view of the recent solutions for mining and covers mining new kinds of patterns, mining patterns under constraints, new kinds of complex data and real-world applications of these concepts.

The problem of mining patterns is becoming a very active research area and efficient techniques have been widely applied to problems in industry, government, and science. From the initial definition and motivated by real-applications, the problem of mining patterns not only addresses the finding of itemsets but also more and more complex patterns.
