摘要
通过对本体知识推理原理的探讨,针对构成本体知识库的本体知识模型与知识规则,完成了土地适宜性评价任务本体与评价知识规则的构建。作为研究重点,以基于AHP的评价因子权重评定方式实现了评价因子权重规则的定义,以指标分值评定的方式实现了评价规则的定义;依据Jena规则语法进行相应规则的形式化表达,实现评价知识规则的获取与存储;以福建省典型亚热带水果荔枝的种植适宜性评价为应用目标,结合本体知识库的构建,实现了应用系统的开发。案例系统的正常运行验证了本体知识库构建方法的有效性。
The ontology knowledge base （OKB） technology is taken to store and apply the experience and knowledge of land suit ability evaluation （LSE） experts. Firstly, the structure of OKB and its reasoning mechanism are discussed. Then, in the light of the composition of ontology model and knowledge rules for an OKB, the LSE ontology model and evaluation rules are constructed for LSE-OKB. The factor weighting rules are defined based on AHP method and the evaluation rules are extracted from the fac tors score assessment. After that, the rules are formatted according to the Jena rule syntax to implement the rule acquisition and storage. At the end, an application system which aims to realize lychee planting suitability evaluation in Fujian area is implemen ted by using the LSE-OKB constructed. The validity of the OKB construction method proposed is verified by the successful eva luation reasoning of the system.
