海洋生态本体建模

Modeling of marine ecology ontology

分析海洋生态领域知识体系特点,提出了海洋生态知识组织模型;借鉴工程领域文献中的"功能"概念描述海洋生态功能过程;参照已有研究提出的功能知识表示框架,确定"设备功能"视点,提出海洋生态领域上层本体,指导构建了海洋生态本体模型和海洋生态形式化本体。扩展基于描述逻辑的Web本体语言OWL-DL,提出了面向过程的OWL-Process模型,构建了海洋生态功能过程-光合作用过程本体的实例。基于海洋生态本体设计开发了海洋生态知识管理系统,实现了海洋生态领域知识的查询和生态危机预警功能,该本体应用系统也验证了海洋生态领域本体构建的有效性、合理性和正确性。

According to characters of marine ecology domain knowledge,a marine ecology knowledge organization model was proposed.Referring to engineering field literature and the device-function knowledge representation theory that the ＂function＂ concept was used to describe marine ecology functional process; a viewpoint of device-function was fixed,a domain upper ontology for marine ecosystem was presented,and then marine ecological conceptual model and marine ecology OWL ontology were constructed.By extending OWL-DL,OWL-Process model oriented function-process was proposed,and then marine ecology function-process ontology instance was constructed.Based on constructed marine ecology ontology repository,marine ecological knowledge management system was developed.The ontology application system provides marine ecology knowledge query and crisis early warning functions; and it also verifies the validity,rationality and feasibility of constructed marine ecology ontology.
