Efficient processing of multiple nested event pattern queries over multi-dimensional event streams based on a triaxial hierarchical model
作者：
Highlights：
• A triaxial hierarchy is proposed to realise the relationships among queries.
• A novel strategy (MQOS) is proposed to find an optimised query execution plan.
• MQOS strategy outperforms other methods even facing the burst input rates.
