Structural Event Detection from Log Messages
We present a method for detecting structural events in log message streams. The approach models log data to identify event patterns without requiring prior domain knowledge, …
Hotspot Detection in Service-Oriented Architectures
We develop a novel algorithm for detecting hotspots in service-oriented architectures. By mining metrics associated with service calls, the method recommends services that are the …
Approximate Graph Mining with Label Costs
We present novel and scalable methods for approximate frequent subgraph mining from exact and probabilistic graphs. By incorporating label costs, the approach yields more …
