[目的/意义] 立足信息资源管理学科，深入剖析南海维权领域的知识内涵与特征，探索南海维权信息资源管理知识体系的建构路径。[方法/过程] 从知识输入、知识搭建、知识对比、知识延伸、知识实践5个环节阐述并剖析南海维权信息资源管理知识体系建构路径。其中，知识输入的目标知识包括南海维权的诉讼标的、法律争点、事实争点、证据争点；知识搭建方法包括知识分类、知识抽取、知识融合、知识关联、知识发现、知识评估；知识对比主要解决南海维权多模态知识的语义融合与关联问题；知识延伸以证据链法理分析、历史证据识别、南海空间分析、智能证据链构建为学科交叉知识边界；知识实践包括证据知识元框架与知识元标引、证据知识元抽取与表示、证据知识元融合与关联以及证据链智库建设。[结果/结论] 南海维权信息资源管理知识体系是信息资源管理“服务国家战略”自主性与“南海维权”功能性的有机统一，有规则地串联起南海维权信息资源，深入地塑造理解南海维权的思维模式，可为信息资源管理学科服务国家重大战略积累宝贵理论知识体系与实践经验。

[Purpose/Significance] Based on the discipline of information resource management, this paper deeply analyzed the knowledge connotation and characteristics of the South China Sea rights protection field, and explored the construction path of the South China Sea rights protection information resource management knowledge system. [Method/Process] This paper elaborated and analyzed the construction path of the knowledge system for South China Sea rights protection information resource management from five aspects: knowledge input, knowledge construction, knowledge comparison, knowledge extension, and knowledge practice. Among them, the target knowledge for knowledge input included the litigation object, legal dispute, factual dispute, and evidence dispute of South China Sea rights protection; knowledge building methods included knowledge classification, knowledge extraction, knowledge fusion, knowledge association, knowledge discovery and knowledge evaluation; knowledge comparison mainly solved the semantic fusion and correlation problem of multimodal knowledge in South China Sea rights protection; knowledge extension took legal analysis of evidence chain, identification of historical evidence, spatial analysis of the South China Sea, and construction of intelligent evidence chain as the interdisciplinary knowledge boundary; knowledge practice included the framework and indexing of evidence knowledge elements, the extraction and representation of evidence knowledge elements, the fusion and association of evidence knowledge elements, and the construction of the evidence chain think tank. [Result/Conclusion] The South China Sea rights protection information resource management knowledge system is an organic unity of the autonomy of the information resource management “serving the national strategy” and the functionality of the “South China Sea rights protection”. It systematically connects the South China Sea rights protection information resources, deeply shapes the thinking mode of understanding the South China Sea rights protection, and accumulates valuable theoretical knowledge system and practical experience for the information resource management discipline to serve the national major strategy.
