Abstract(in English) | There have been attempts to apply collaborative filtering to service recommendation. Most all of them are for atomic service by collaborative filtering using explicit evaluation value by users. However, in real world, it is difficult to get explicit feedback from users, and there are composite services in addition to atomic services. In this paper, we propose multi-stage collaborative filtering using invocation count as evaluation value in order to prevent users from giving feedback and to take account of service composition in composite services. Focusing on nested structure in composite service, our method make evaluation value matrix for each set of services that might be invoked by composite service, and apply collaborative filtering repeatedly until executable services are recommended to user. We applied proposed method to service recommendation on the Language Grid, and verified the effectiveness of multi-stage collaborative filtering and measured recommendation accuracy. |
