Mining Disjunctive Sequential Patterns from News Stream
説明
Frequent disjunctive pattern is known to be a sophisticated method of text mining in a single document that satisfies antimonotonicity, by which we can discuss efficient algorithm based on APRIORI. In this work, we propose a new online and single-pass algorithm by which we can extract current frequent disjunctive patterns by a weighting method for past events from a news stream. And we discuss some experimental results.
