| 摘 要： | 在当前词共现分析多关注两词共现分析的基础上,提出多词共现分析方法,并采用关联规则挖掘中的频繁项集抽取法,实现多词共现的抽取和与分析.以我国国家知识产权局专利数据库(SIPOD)中数字信息的传输领域(H04L)为例,抽取和深入分析该领域中词最多的多词集合和频数最大的多词集合.最后,结合当前文献计量学中研究热点的定义与识别,应用多词共现分析方法发现H04L领域中的6个研究热点,进而对这6个研究热点中的部分代表性专利文献进行介绍.

| Abstract: | The co-word analysis pays more attention to the two words co-occurrence analysis,the paper proposes multiple words co-occurrence analysis.Based on the frequent item extraction method in the association rule mining,it achieves extraction and analysis of the co-occurrence of multiple words.Taking the field of digital information transmission (HO4L) in the State Intellectual Property Office Database (SIPOD) for example,this paper exacts and deeply analyzes its most frequent words set and the longest words set.At last,based on the analysis and review on the current research hotspots in the bibliometrics,it finds that the six research hotspots in the field of HO4L.The paper introduces part of representative patents on 6 hotspots. |
