Abstract:

Recommender system has been recognizedas a superior way for solving personal information overload problem.More and more aspect-based models are leveraging user ratings and extracting information from review texts to support recommendation.Aspect-based latent factor model predicts user ratings relying on latent aspect inferred from user reviews.It usually constructs only a single global model for all users,which may be not sufficient to capture the diversity of users' preferences and leave some items or users be badly modeled.We propose a Hybrid aspect-based latent factor model (HALFM),which jointly optimizes the Global aspect-based latent factor model (GALFM) and the Local Aspect-based Latent Factor Models (LALFM),their user-specific combination,and the assignment of users to the LALFMs.HALFM makes prediction by combining user-specific of GALFM and many LALFMs.Experimental results demonstrate that the proposed HALFM outperforms most of aspect-based recommendation techniques in rating prediction.
