摘　　要：针对中国与东盟国家在知识共享过程中的语言障碍问题,详细阐述跨语言查询扩展元组空间的逻辑结构,提出U-P2P网络模式下元组空间知识协作的分布式中、越跨语言查询扩展模型。在此基础上,增加查询扩展代理peer的动作语言规则的定义和元组元操作指令集,依据强化学习算法提出一种基于加权矩阵的自适应路由选择/查询机制。在Gnutella环境下的实验表明,相对于传统的集中式查询而言,该模型对中越两种语言之间的快速翻译和扩展查询具有较好的准确率和召回率,在不同知识领域的运用中具有通用性和可扩充性。Aiming to the problem of language barrier about knowledge sharing between China and ASEAN countries,this paper expounded the logical structure of tuple space on cross-language query expansion,and proposed a distribute Chinese-Vietnamese cross-language query expansion model for knowledge collaboration on tuple space based on U-P2P network model.It added the definition of the action language rules and instruction set of tuple operations about query expansion proxy,gave an adaptive routing/query mechanism with weighted matrix according to reinforcement learning algorithm.Relative to centralized query,the experiments in Gnutella network show that the model has a better recall and precision in rapid translation and extends query between Chinese and Vietnamese,and possesses versatility and scalability in the use of the different fields of knowledge.
