摘要
将文本挖掘和共词分析方法相结合应用到专利文献的研究中去,以期通过对专利的内容分析更深层次地了解不同技术主题的研究现状及发展趋势。以射频识别(Radio Frequency Identification,RFID)技术领域为研究对象,对此领域专利的摘要进行文本挖掘,从中提取能够反映此技术领域特征的关键词,根据关键词之间的共现关系,对其进行聚类分析,得到目前RFID领域的六个技术主题,并借助战略坐标图对这六个技术主题进行分析,探寻每个技术主题的发展趋势,为企业技术创新活动和产业发展战略的制定提供决策参考。
The paper applied text mining and co -word analysis methods in patent analysis to deeply identify the current situation and trend of development in technology topics based on patent content analysis. Taking RFID for example, integra- ting the method of text mining, it extracted the key words that reflect the characteristics of this technical field from the ab- stract of patents. By analyzing the occurrence of each key word, six technology topics of RFID were obtained by applying the method of cluster analysis. The paper analyzed six technology topics and explored the development of each technology topic with the benefit of strategic diagram, it is useful to provide ed decision - making reference for enterprise technical in- novation and industrial development strategy.
