“…Other attempts focused on combining domain knowledge with historical events in the rule learning process, such as the SCEP ter framework proposed by Zhou et al [24]. Despite the partial success in automating the CEP rule generation process either by fine tuning existing CEP rules [23,25] or by generating entirely new pattern rules [20,21], dealing with the increased number of rules is still a challenging task. Precisely, the increased number of CEP detection rules leads to more complex detection patterns, which makes the targeted situation more complicated to comprehend and handle [12,20,26]; furthermore, such an increase also brings higher levels of computational complexity [27].…”
