The 18 articles during this cutting-edge survey current the newest leads to inductive querying and constraint-based info mining and in addition determine destiny instructions of this newly rising box mendacity on the intersection of knowledge mining and database examine. The papers deal with topical sections on foundations of inductive database frameworks, optimizing inductive queries on neighborhood styles, optimizing inductive queries on international styles, and purposes of inductive querying techniques.

Example text

The potential efficient evaluation of the proposed primitive is discussed in Section 4 and 5; here we advocate its adequate expressiveness and versatility showing how it can be embedded in query languages of different flavour. Example 14 (Embedding the primitive in a SQL-like language). Consider the constraint-based frequent pattern query of Example 13. The following is some SQL-like syntactic sugar to express such query. MINE PATTERNS Freq_pat, Support FROM sales GROUPING item BY day,cust MINIMUM SUPPORT: 3 CONSTRAINTS ON name FROM product HAVING SUM(price) >= 30, In the first line we define the name of the two output attributes Freq pat and Support corresponding to the variables I and S of the query in Example 13.

In [48, 49], two FP-growth based algorithms are introduced: F IC A to mine Th(Cfreq ) ∩ Th(CCAM ), and F IC M to mine Th(Cfreq )∩Th(CCM ). A major limitation of any FP-growth based algorithm is that the initial database (internally compressed in the prefix-tree structure) and all intermediate projected databases must fit into main memory. If this requirement cannot be met, these approaches can simply not be applied anymore. This problem is even harder with F IC A and F IC M : in fact, using an order on items different from the frequency-based one, makes the prefixtree lose its compressing power.
