【摘要】:電子商務(wù)(E-commerce)的飛速發(fā)展,產(chǎn)生了大量針對商品的在線評級數(shù)據(jù),通過分析評級數(shù)據(jù),用戶可以對商品的質(zhì)量進行評估.然而,評級數(shù)據(jù)的海量性和差異性使得用戶難以快速而準確地評估商品的質(zhì)量.鑒于此,提出一種基于E-commerce評級的上下文感知賦權(quán)方法(context-aware weighting approach,CWA),以選出少數(shù)"重要"的評級數(shù)據(jù)并拋棄大多數(shù)"不重要"的評級數(shù)據(jù),從而確保商品質(zhì)量評估的快速性和準確性.最后,通過一組實驗驗證了CWA的有效性.
[Abstract]:With the rapid development of E-Commerce, a large number of online rating data for commodities have been generated. By analyzing the rating data, users can evaluate the quality of goods. However, the mass and diversity of rating data make it difficult for users to evaluate the quality of goods quickly and accurately. In view of this, a context-aware weighting approach based on E-commerce rating is proposed to select a few "important" rating data and discard most of the "unimportant" rating data, so as to ensure the speed and accuracy of commodity quality assessment. Finally, the effectiveness of CWA is verified by a group of experiments.
