Jan Rauch, Milan Šimůnek
2011 Lecture Notes in Computer Science  
First experiences with utilization of formalized items of domain knowledge in a process of association rules mining are described.  ...  We use association rules -atomic consequences of items of domain knowledge and suitable deduction rules to filter out uninteresting association rules.  ...  We apply the 4ft-Miner procedure for mining association rules. It deals with Boolean expressions built from attribute-set of value.  ...

The GUHA method and its meaning for data mining

Petr Hájek, Martin Holeňa, Jan Rauch
2010 Journal of computer and system sciences (Print)  
The reader easily recognizes similarity with the notion of an "associational rule with support and confidence" introduced by Agrawal [1] about 25 years later: his A and S are elementary conjunctions containing  ...  For the system LISp-Miner and similar (implemented) systems generalizing GUHA see Section 2; for GUHA using fuzzy logic see Section 3. For some related computer systems see [27, 65, 112,113].  ...  The procedure 4ft-Miner [83, 97] is the enhanced procedure ASSOC [20, 28] . The 4ft-Miner mines for association rules ϕ ≈ ψ and for conditional association rules ϕ ≈ ψ/γ .  ...
