A mining algorithm using downward closure property of relational attribute
JSAI Technical Report, Type 2 SIG
This paper proposes an algorithm for relational frequent pattern mining based on logical structure of examples. It uses bottom-up property extraction from examples. The extracted properties construct patterns by two operations. One of the operations combines patterns as their conjunction, and the other makes a pattern as it keeps structure appeared in examples. We show a kind of downward closure property among patterns constructed by the operations. By using the property we give a miningdoi:10.11517/jsaisigtwo.2008.dmsm-a703_11 fatcat:b7j7ggnahzbsddwd4b5rtoc4jy
