一种三级技术机会识别方法及其应用——基于SAO语义分析和多维技术创新地图

精准识别技术创新机会对于企业在复杂多变的市场竞争环境中立于不败之地至关重要。首先，基于SAO（Subject-Action-Object，主语-谓语-宾语）语义分析，从专利文本中抽取SAO结构；其次，以多维技术创新地图创新维度为导航，构建具象技术创新维度初始词典，利用SAO语义相似度计算和主题聚类，进一步构建基于创新维度的三级语义知识库；再次，运用多维技术创新地图的创新法则及维法耦合原理对基于创新维度的三级语义知识库进行迭代变换，实现技术形态、创新子维、创新维度三级技术机会识别；最后，以3D打印机领域为例验证研究方法的可行性和有效性，可为企业高效、精准识别技术创新机会提供参考依据。

A Three Level Method for Technology Opportunity Identification and Its Application based on SAO Semantic Analysis and Multidimensional Map of Technology Innovation

It is critical for enterprises to accurately identify technological opportunities in the complex and changeable market competition environment.The Subject-Action-Object (SAO) structures were extracted from the patent texts by SAO semantic analysis.Guided by the innovation dimension of multidimensional map of technology innovation, the three-level semantic knowledge base of innovation dimension was constructed by semantic similarity and topic clustering based on the initial dictionary of innovation dimension in the field of concrete technology.Then, the three-level semantic knowledge base based on innovation dimension was iterated by using the coupling principle of innovation dimension and innovation rules to identify the technology opportunities at three levels of technical morphologies, innovation sub-dimensions and innovation dimensions.Finally, the feasibility and effectiveness of the proposed method were verified by taking 3D printer as an example.The proposed method integrating the SAO semantic analysis and multidimensional map of technology innovation can provide a scientific decision reference for enterprises to accurately identify technology opportunities efficiently and accurately.
