摘  要:实景三维地理实体语义化是构建数字中国统一三维时空基底的核心环节,对于实现信息的高效流通共享及推动行业高质量发展具有关键作用。关系语义建模是实现实体语义化的关键步骤,然而,目前关系语义建模面临着标准化程度不足、可扩展性较差和跨领域交叉应用等挑战。本文提出一种顾及多领域的实景三维地理实体关系语义建模框架,采用标准化和通用化的方法来表达与存储地理实体间的关系语义,以确保语义信息的准确性和一致性;并以社区燃气管道泄漏的应急处置应用场景为例,详细验证并阐述关系语义建模框架的应用方法,展示其在多行业领域中的兼容性和扩展性。研究表明,本文方法可有效地促进不同行业领域间地理实体语义信息的互联互通,具有一定的推广价值和应用前景,能够为相关领域的信息化建设和服务提供有力支持。This thesis focuses on industry applications and proposes a framework for semantic modeling of geo-entity relationships 3D realistic geospatial landscape model,compatible with multiple domains.[Objective]Semanticizing of geo-entities in 3D realistic geospatial landscape model is crucial for constructing a unified 3D spatiotemporal substrate for Digital China.This process facilitates efficient information circulation and sharing,promoting high-quality industry development.However,current semantic modeling of relationships faces challenges such as insufficient standardization,poor scalability,and difficulty in cross-domain application.Establishing and enhancing this framework along with optimizing the relational semantic construction method,are essential for advancing the entire chain from high-quality data production to multi-domain applications.Therefore,we need to create a robust and practical semantic modeling framework.[Method]By analyzing the multi-dimensional characteristics of geo-entities in 3D realistic geospatial landscape model domains,this paper delves into the content of the geo-entity semantic model system,and underscores the necessity of developing a semantic modeling framework.We proposes a framework that considers multiple domains formed by defining relationship types and description rules.Standardized and generalized methods ensure the accurate and consistent expression and storage of relationship semantics among geo-entities.Building on this basic framework,we add a new relationship domain index or extend the relationship triggering feature conditions to accommodate different business applications.[Result]Using the emergency disposal scenario of community gas pipeline leakage as an example,this paper validates and elaborates on the application of the semantic modeling framework in detail.The researcher integrates proprietary relationship types and corresponding description rules from extended domains like real estate rights,and emergency security,to construct a multi-domain compatible semantic m
