Querying multiple sets of discovered rules

Abstract: Rule mining is an important data mining task that has been applied to numerous real-world applications. Often a rule mining system generates a large number of rules and only a small subset of them is really useful in applications. Although there exist some systems allowing the user to query the discovered rules, they are less suitable for complex ad hoc querying of multiple data mining rulebases to retrieve interesting rules. In this paper, we propose a new powerful rule query language Rule-QL for querying mul… Show more

“…Winarko and Roddick [23] use signature files to index temporal patterns. Tuzhilin et al [20] use B+ trees to index the support and the confidence of the rules and use inverted files to index patterns. In Opportunity Map [12], a hash-tree is used to store classification rules.…”

“…In this domain, few works have been done nowadays. The most significant one is probably RULE-QL (Tuzhilin and Liu, 2002) which proposes an extension of SQL allowing some kind of management for association rules. Nevertheless, such a language only offers some very basic functionalities such as accessing some parts of rules, searching for rules containing a particular item in their left or right part, etc.…”

“…A solution can come from query languages dedicated to pattern database manipulations. It is the case of RULE-QL (Tuzhilin and Liu, 2002) which extends SQL with operators allowing to access rules components and to specify subset relationships. It is thus easier to write queries that, for instance, select rules that have a left part contained in the consequent of another rule.…”
