农业领域技术分类体系自动构建研究

Research on Automatic Construction of Technology Classification System in Agricultural Field

[目的/意义]当今农业科技领域发展迅速,农业领域学科变化多样,现有传统经典的分类体系不适用于当前呈现交叉性融合性发展趋势的农业领域。构建适用于农业发展现状的农业技术分类体系值得关注。[方法/过程]在经典传统分类的基础上,综合多种数据来源,从定性和定量两个视角,结合主题词共现、引文耦合,以及人工调整的方法,构建了一套农业技术分类体系。并从规模、方法、农业学科布局现状和农业领域发展趋势等四个方面阐述了分类的合理性。[结果/结论]本研究提出的农业技术分类方法较为合理,在农业领域有一定的适用性,并就当今农业领域研究发展趋势和分类体系的构建提出了相关建议。

[Purpose/significance]Nowadays,the field of agricultural science and technology is developing rapidly,and the disciplines in the field of agriculture are diverse.However,the existing traditional classic classification system is not suitable for the current agricultural field,which shows the trend of interdisciplinary and integrated development.It is worthy of attention to construct an agricultural technology classification system suitable for the current situation of agricultural development.[Method/process]On the basis of classic traditional classifications,this paper integrates a variety of data sources,and constructs a set of agricultural technology classification system from both qualitative and quantitative perspectives,combined with the methods of subject word co-occurrence,citation coupling,and manual adjustment.This paper further expounds the rationality of classification from four aspects:scale,method,current situation of agricultural discipline layout and development trend of agricultural field.[Result/conclusion]The classification method of agricultural technology proposed in this study is reasonable and has certain applicability in the field of agriculture,and puts forward relevant suggestions on the development trend of current agricultural research and the construction of classification system.
