多维情境融合的移动情境感知服务系统构建研究
|
摘要
文章从多维情境融合的角度,构建了移动情境感知服务系统的模型,该模型可以为用户进行准确的个性化推荐服务。首先对多维情境数据信息的采集、预处理以及移动个性化推荐等方面进行了论述,对多维情境融合下的用户行为特征进行了提取,再结合情境的相似度,为用户进行个性化推荐;其次探讨了移动用户交互对个性化推荐服务的影响;最后通过实验,论证了融合多维情境的移动情境感知服务系统可以提高推荐的准确性。
From the perspective of multidimensional context convergence,this paper constructs a model of mobile context aware service system,which can provide users with accurate personalized recommendation service. Firstly,the paper discusses the multidimensional context data information collection,preprocessing and mobile personalized recommendation,obtains the user behavior characteristic under the multidimensional context convergence. Then combined with the similarity of contexts,it provides personalized recommendations for users. Next,the paper discusses the influence of mobile user interaction on the personalized recommendation service. Finally,the experiment demonstrates that mobile context aware service system with multidimensional context convergence can improve the accuracy of recommendation.
