Abstract

The event sequence of the same type from a set of events having time property can be summarized in one event. But if the event sequence having an interval, It is reasonable to be summarized more than one in independent sub event sequence of each other. In this paper, we suggest a method of temporal data mining that summarizes the interval events based on Allen's interval algebra and finds out interval event association rule from interval events. It provides better knowledge than others by using concept of an independent sub sequence and finding interval event association rules.

시간 속성을 갖는 이벤트 집합에서 동일한 이벤트 타입에 대한 이벤트 시퀀스는 하나의 이벤트로 요약될 수 있다. 그러나 정의된 시간 간격이 경과된 후 발생된 이벤트 타입은 하나 이상의 독립된 서브 이벤트 시퀀스로 요약하는 것이 바람직하다. 본 논문은 Allen의 시간 관계 대수에 기반하여 인터벌 이벤트를 요약하고, 요약된 인터벌 이벤트들로부터 인터벌 연관 규칙을 찾아내는 새로운 시간 데이터 마이닝 기법을 제안한다. 제안하는 기법은 독립적인 서브 시퀀스 개념을 도입하고 인터벌 이벤트 사이의 연관 규칙을 탐사함으로써 질적으로 우수한 정보를 제공한다.
