Hot spots and trend analysis of traceability research in China under the new generation information technology environment

Abstract

The new generation of information technology is gradually being applied to various fields. Information technology represented by the Internet of Things and blockchain is applied to traceability, which solves the problems of original traceability information distortion, high collection cost, and multi-link information interoperability, and injects new vitality into traceability research. This paper sorted out 1184 selected documents on the traceability topic in the new generation of information technology environment from 2010 to 2019. In order to interpret the connotation of the theme, calculate the information gain of 1609 keywords to 17 categories of themes, and select the top five keywords of each theme's information gain to analyze the theme connotation. The 17 topics are mainly divided into initial exploration topics, current hot topics, future trend topics, and stable topics through literature time series analysis. The research results are as follows: from the subject point of view, the research on "Traceability + Radio Frequency Identification" has been relatively mature; "Traceability + Blockchain", "Traceability + Internet of Things" and others are current research hotspots. Eight categories of themes such as "traceability + QR code", "source traceability + big data", "quality and safety" are in the initial exploration period, their subsequent evolutions are determined on social needs and the development of technology.
