Research on recommendation of Web services based on QoS execution information

Services discovery based on the non-functiona(lQoS) service features has received increasing attention by service-ori-ented computing research community.In order to overcome QoS characteristics which is difficult to acquire accurately and dynamic changes,in this paper,a services recommendation approach based on past QoS implementation information is proposed.The frame-work of services recommendation which can record the log easily is presented firstly.Then,a time-weighted matching algorithm is proposed to implementation services recommendation.Experimental results show that the new approach is feasible and effective.
