针对专利分析对法律状态需求量庞大而法律状态需单项获取的矛盾,设计并实现基于网络的法律状态信息采集系统。系统通过分布式架构启动多台机器进行搜索,通过一致性Hash算法并引入虚拟客户节点,克服进程分配中的不均衡问题,配合以网页识别,实现包括法律状态在内的专利信息批量、经济、快速获取,有效解决专利现状分析中的数据获取瓶颈问题。实例表明,融入法律状态的专利分析,能使分析结果更为全面、客观和丰富,并更具针对性。 Aiming at the contradiction between the huge demand of legal status and the legal status of patent analysis, this paper designs and realizes the legal status information collection system based on internet. The system starts the search of multiple machines through the distributed architecture, through the Hash algorithm and the introduction of virtual customer nodes to overcome the imbalance in the process of distribution, with the webpage recognition, including legal status, including patent information bulk, economic, Quickly obtain and effectively solve the bottleneck problem of data acquisition in the analysis of patent status quo. The examples show that patent analysis integrated into legal status can make the analysis more comprehensive, objective and rich, and more targeted.
