基于专利SAO链的技术预见方法研究 ——以工业机器人领域为例

针对专利文本挖掘领域,提出一种构建SAO链的规则,将专利文本使用SAO链进行特征表示,充分利用技术的层次和内容两部分信息,使专利文本相似度计算更加准确,然后围绕该方法构建一套科学合理的技术预见方法体系。最后,以工业机器人领域为例进行实证研究,通过分析专利网络得到该领域的技术发展路径图,通过专利地图识别出该领域的五个技术机遇,为企业和政府提供可借鉴的情报信息。

Research on technology foresight method based on patent SAO chain:Taking Industrial Robot Technology as an Example

Patent mining is one of the core methods of technology foresight, which can obtain high-value technical information contained in patents and provide decision-making support for the government to formulate strategies and enterprise R D plans. Aiming at the field of patent text mining, this paper puts forward a rule of constructing SAO chain, and using SAO chain for feature representation of patent text, and making full use of the technical level and content information, which makes the calculation of patent text similarity more accurate, then constructs a scientific and reasonable technology prediction method system around this method. Finally, an empirical study is carried out in the field of industrial robots. Through analyzing the patent network, the technology roadmap in this field is obtained. And five future technological opportunities in this field are identified through the patent map, which provides useful information for relevant enterprises and governments.
