基于知识图谱的国际搜索引擎研究历程与热点演进

The Research Course and Focuses Evolution of International Search Engine Based on Knowledge Mapping

摘要:

对国际上搜索引擎领域的研究文献进行了比较细致、深入的考察,采用可视化方法进行定量分析并制作了有关知识图谱,明晰了国际搜索引擎研究的总体趋势和发展脉络。通过对高被引文献的深入解读和定性分析,以及近几年相关文献的共词分析,揭示了国际上搜索引擎研究的起源和发展,以及从进入快速发展期至今四个阶段的研究热点演进历程。最后,总结和展望了国际搜索引擎研究的热点方向。

Abstract:

The international research literatures about search engine are investigated detailedly and deeply, and analyzed quantitatively using visualization methods. Knowledge maps for it are drawn, which can show the general trend and evolution course of the international research on search engine clearly. Through the interpretation and qualitative analysis of highly cited literatures, and the co-word analysis of the literatures in recent years, we represent the origin and development of international research on search engine, and the evolution course of research focus in the four stages from the period of rapid development to this day. At last, we summarize and look forward the main trends of international research on search engine.
