Abstract

Temporal data can capture the behavior of phenomena such as accidents along a highway, weather trend such as precipitation or snow totals in a region over time. Traditional temporal data mining has looked at patterns, such as anomalies, in each temporal data stream. However, to study real world phenomena and interrelationships between them, in this theses, we propose a novel approach to discover the temporal relations between multiple distinct domains represented by multiple distinct temporal data collected at a location. Our goal is to discover the relationship between distinct domains using interesting temporal events in them. These interesting temporal events are mined using traditional temporal anomaly detection methods. Relations between two application domains are not always simple since there can be some time-delay in these relationships. So, focusing on relations found using intersecting time events alone is not sufficient. Hence, we employ the concept of not only direct overlap but also proximity between temporal events across domains to find the direct and time-delayed relationships. We have achieved an optimistic result after our experiment on MATCH, NJDOT and weather data.
