It is essential that we compare our proposed methods against a true baseline (an existing, well known method). I have selected two methods from two papers (listed below), and is currently in the process of selecting the one to be implemented.
Krestel, R., Fankhauser, P., & Nejdl, W. (2009). Latent dirichlet allocation for tag recommendation. Proceedings of the third ACM conference on Recommender systems RecSys 09, 61. ACM Press. doi:10.1145/1639714.1639726
Heymann, P., Ramage, D., & Garcia-Molina, H. (2008). Social tag prediction. (S. H. Myaeng, D. W. Oard, F. Sebastiani, T. S. Chua, & M. K. Leong, Eds.)Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval SIGIR 08, 31(4), 531. ACM Press. doi:10.1145/1390334.1390425
Once the base line is implemented, it will be tested with our proposed methods.
