基于引文内容分析的交叉领域知识内化过程研究

Analyzing the Knowledge Internalization Process of Interdisciplinary Field Based on Citation Content

【目的/意义】不同学科知识的相互整合是交叉研究领域形成和发展的基础。对交叉领域知识整合过程的理解有助于促进交叉领域的知识发现和知识创新。【方法/过程】本文利用自然语言处理技术,从交叉领域文献题录数据、引文上下文和参考文献文本信息中抽取知识短语,以引证关系和词汇匹配关系为线索,提出吸纳知识和内化知识的识别方法,深入揭示交叉领域中“知识吸纳-知识内化”的知识整合过程。【结果/结论】以电子健康领域(eHealth)为例,揭示了该领域的知识内化总体特征和不同来源学科所提供知识的内化特征差异。【创新/局限】本文结合引文内容对交叉领域知识内化过程进行量化分析,提出了一种新颖的全文本量化分析方法,为理解交叉领域的知识生长过程提供了新的视角和分析方法。未来研究可以结合参考文献全文以进一步优化这一方法,同时在更多的交叉研究领域开展实证。

【Purpose/significance】The integration of knowledge from multiple disciplines is the basis for the formation and development of interdisciplinary fields. Understanding the knowledge integration process of the interdisciplinary field is helpful for knowledge discovery and knowledge creation in the field.【Method/process】In this study, we apply natural language processing technology to extract knowledge phrases from the metadata, citation context, and reference text of an interdisciplinary field. Then, we take the citation relations and phrase matching relations as clues to identify knowledge absorbed and internalized in the field, and reveal the "knowledge absorption-knowledge internalization" process of the field.【Result/conclusion】Taking the eHealth field as an exemplar interdisciplinary field to conduct a case study, the results reveal the general characteristics of knowledge internalization in the field and the differences in characteristics of internalized knowledge provided by different source disciplines.【Innovation/limitation】The process of internalization of cross domain knowledge is quantitatively analyzed by combining with citation content, which contributes a novel method of full-text quantitative analysis. The proposed methodology provided new insights into the knowledge formation of an interdisciplinary field. Future studies can use the full text of references to further optimize this method, and carry out empirical research on more interdisciplinary fields.
