知识网格技术是网格技术、Web服务与语义网相结合的新兴技术。针对知识网格技术的要求与发展趋势,首先构建简单的用户模型架构,在架构的基础上对各模块算法进行介绍,进而提出一种自适应更新的用户模型计算方法,以实现用户模型的自适应更新功能。经实验验证,该方法提高用户模型的适应性与准确性,降低建立模型时对用户信息的要求。
Knowledge grid technology is a new technology that combines grid technology and Web services with semantic web. According to the requirements and development trend of knowledge grid technology, we construct a simple user model architecture and introduce each module algorithm on the basis of architecture. Then we propose a self-adaptive updating user model calculation method to realize the self- Adapt to update features. The experimental verification shows that this method can improve the adaptability and accuracy of the user model and reduce the requirement of user information when establishing the model.
