Abstract

With the fast development of E-commerce, large amounts of quality rating data for commodities are generated online. By analyzing the rating data, users can evaluate the commodities’quality. However, due to the massiveness and diversity of the rating data, it is a challenge for users to evaluate the commodity quality quickly and accurately. To this end, a context-aware weighting approach for E-commerce ratings, context-aware weighting approach (CWA) is proposed. With CWA, a few important rating data are selected and most unimportant data dropped. Thus the commodity quality can be evaluated quickly and accurately. A series of experiments validate effectiveness of the proposed CWA.

Key words： big data; context; E-commerce; user rating; weighting
