基于多属性的专利知识表征与组织

针对专利知识传统获取方式中存在的技术领域局限,利用矛盾、物质-场、功能、发明原理、标准解和效应等6种创新属性构建专利知识多属性表征模型;每种创新属性均采用对应的属性层次树进行多层次描述,并由此提出了基于多属性的专利知识多层次组织策略及算法流程;在此基础上,给出了基于该模型的应用框架.通过上述方法构建得到基于多属性多层次的本地专利库,从多个属性角度对专利知识进行综合表征,并支撑不同层次专利知识的获取.从而,打破了技术领域的局限,促进跨学科、跨领域专利知识的快速、有效获取,有利于激发设计人员进行类比迁移.最后,通过微纳空心镍球制备方法的改进示例说明该模型的可行性.

Patent knowledge representation and organization based on multi-attribute

Aiming at the technology limitation existing in traditional patent acquisitions,six types of innovative attributes were used to construct a multi-attribute representation model for patent knowledge:contradiction,substance-field,function,inventive principle,inventive standard and effect.In addition,each innovative attribute could be described by the corresponding attribute-hi-erarchy tree,thus the specific organization strategy as well as the algorithm process were presen-ted to organize patents from different levels of abstraction.Furthermore,an application frame-work based on the above model was put forward.As a result,a local patent database was con-structed based on multi-attribute and multi-level,which could support the comprehensive expres-sion from different attribute views and the effective obtaining in different levels for patent knowl-edge.In conclusion,it was conducive to break the limitation of technological field and promote the efficient obtaining of cross-disciplinary and cross-field patent knowledge,which could help de-signers get inspiration in the process of analogical transferring.Finally,the case of nanometer-sized hollow nickel spheres was used to demonstrate the practicability of the model.
