Research on Real-time Recommendation Method of IoT Services Based on Event Correlations
Due to the uncertainty of user needs and environment,service composition business processes may need to be dy-namically adjusted at runtime.Therefore,recommending IoT services that better meet immediate needs for users has become one of the key issues that need to be solved urgently.On the issue of how to improve the immediacy and accuracy of IoT service recommen-dation in business processes,a method for instant recommendation of IoT services considering time delay is proposed.Based on the improved CM-SPADE algorithm,frequent event association patterns with delay attributes are mined.Recommend IoT services that meet time constraints to users more accurately Recommend IoT services that meet time constraints to users more accurately,so as to better adapt to changes in business processes.Experimental results show that the proposed IoT service recommendation method con-sidering time constraints shows a good performance in improving service recommendation accuracy.
