摘　　要：在分析Presence信息特征的基础上，提出了Presence模型的建模需求和功能目标，并指出：信息共享、隐私保护以及信息融合要求对信息提供一致的管理方式，可通过建立Presence信息模型来解决这一问题，信息模型的建立应该直观和易用。根据建模需求对适用的建模方法进行了比较，建立了一种新的面向普通应用开发者的混合建模方法，结合图形化建模和本体建模的优点，在建模过程引入了模型驱动结构（MDA）方法和工程化思想，标准化的表达方式和规范的建模步骤保证了建模的质量。On the basis of analyzing the features of Presence information, the requirements of Presence modeling were presented, and the points that the functional goals of the modeling such as information sharing, privacy protecting and information fusion need a consistent information management, the management can be resolved by establishing a Presence information model, and the model should be simple and intuitional were suggested. Based on the comparison of some suitable modeling approaches with the requirements, a novel hybrid modeling approach facing common application developers was established, which combined the predominance of both the graphic-based modeling and the ontology-based modeling. The modeling quality was assured by the methodology of the model driven architecture （MDA） and the engineering modeling.
