    This paper analyzes the similarity between Ontology structure and object-oriented data model, and constructs Ontology topology structure when stores Ontology in object-oriented database. Then it puts forward a method of transforming Ontology to object-oriented data model,and designs the storage class of Ontology topology structure. The Ontology topology structure stores Ontology concepts in core class and stores the complex relation of Ontology in relationship class to keep the network information of Ontology dynamically and integrally. Finally, the storage of Ontology topology structure is verified through aviation weapon suspension launch equipment examples.

    This paper introduces an automatic construction method for domain Ontology implemented by words co-occurrence analysis in both document and citation. This Ontology adopts weighted XML model and uses weight in concepts and their relationship to express the difference of users' interest effectively,which can improve the ability of expressing users' interest and their relationship with centripetal weight spreading activation strategy in order to explore more valuable users' interest. Meantime, this paper also discusses how to use this Ontology to transform heterogeneous user personalized profile to consistent comparable model with the broken-and-reconstruction strategy, and how to match corresponding heterogeneous user personalized profile in detail. Finally, the result of correlative tests and experiments are concluded.

    This paper uses the algorithm of auto-learning rules combining with leading words to implement the semantic markup of species description text in Chinese with the data set of 1 000 documents collected from Flora of China randomly. Experimental results indicate that the whole markup efficiency (the values of F) of rule-based algorithm, which is designed by the study, generally reaches 0.930, and most elements are in the range of 0.724-0.964. Therefore, this algorithm is better than Naive Bayesian categorization algorithm, and it is also proved that leading words are positive for optimizing the algorithm.
