针对地质大数据与成矿知识割裂导致的共伴生关系建模难题,亟需构建支撑智能分析的知识方法体系. 提出一种数据-知识协同驱动的知识图谱构建方法,融合领域本体与BERT⁃BiLSTM⁃CRF模型,通过“知识引导-数据反馈”机制实现本体演化与信息抽取的动态协同,系统地从多源地质文本中提取矿床特征与共伴生关系,建立勘查数据与成矿知识间的语义映射. 实验表明:实体识别F1值达83.2%,较基线提升15.4%;实体重复率降低5.7个百分点,图谱一致性显著改善. 最终构建包含1.2万节点与2.8万关系的结构化知识图谱,支撑可视化分析、智能问答、成矿预测及平台服务. 该方法实现了知识与数据的深度融合,为矿产勘查向数据-知识协同驱动的智能范式转型提供了可解释、可操作的技术路径.
The growing disconnect between geological big data and metallogenic knowledge poses a significant challenge to modeling co⁃associated mineral relationships, underscoring the urgent need for a knowledge⁃based methodology capable of supporting intelligent analysis. To address this, we propose a data⁃knowledge synergy⁃driven approach for constructing knowledge graphs, which integrates domain ontology with the BERT⁃BiLSTM⁃CRF model. By leveraging a “knowledge⁃guided, data⁃informed” mechanism, the method enables dynamic collaboration between ontology evolution and information extraction, systematically identifying ore deposit features and co⁃associated relationships from multi⁃source geological texts and establishing semantic mappings between exploration data and metallogenic knowledge. Experimental results show that entity recognition achieves an F1 score of 83.2%, representing a 15.4 percentage⁃point improvement over the baseline; entity redundancy is reduced by 5.7 percentage points, markedly enhancing graph consistency. The resulting structured knowledge graph, which comprises 12,000 nodes and 28,000 relations, has been deployed in visualization analysis, intelligent question answering, mineralization prediction, and data platform services. This work realizes deep integration of data and knowledge, offering an interpretable and actionable technical pathway for transforming mineral exploration from an experience⁃driven paradigm to one driven by data⁃knowledge synergy.
