    This paper briefly surveys the state-of-the-art of construction and evolution of domain Ontology. It describes the process to construct a primary version of economics Ontology from existing Chinese classified thesaurus, and the approach to evolve the primary version of the domain Ontology. The key techniques of Ontology evolution include creating a dataset for Ontology learning, determining the candidate keywords, and discovering the concepts and relationship of the domain Ontology.

    This paper puts forward the framework and functions of the OAI-PMH based interoperation of digital archives and after one of the main digital archival metadatas EAD and its mapping with DC, which is generally supported by OAI-PMH, are introduced, the technical principles on how EAD can be shifted into DC, and particularly, how the context information between EAD subordinate components can be kept after being shifted into OAI records, are discussed. At last, the existing problems in the process are analyzed, and some solutions are advanced.

    This paper studies some issues related with intelligent information retrieval. Firstly, the method for calculating semantic similarity and relativity by use of taxonomy and entailment relations of Ontology is proposed, by which query expansion can be implemented. Secondly, by use of the relations in Ontology, keywords queries are standardized and re-construct in the form of RDF. Finally, the scheme is proved reasonable and valid by concrete tests and analysis.

    The paper puts forward an approach of Ontology-based rule classification. Firstly, the approach creates Ontology for each subclass of the classification system. Then, the Web texts classification is performed using the rules and Ontology. Comparing with the method of Rocchio, the results of the experiments indicate that the recall of Ontology-based approach is slightly lower than Rocchio’s, but its precision is more eminent than Rocchio’s.

    Based on Vector Space Model(VSM) and Nave-Bayes(NB), completed a multilayer and multi-classification text categorization system. Introduce detailedly four modules: words’ segmentation and frequency statistics, calculating between classifications’ and document, emendating the veracity of parent-class by emendation of subclass, judging whether document has multi-classification and multi-label. Text representation based on Vector Space Model has 89.7% MicroF1 of parent- category, 77.8% of sub- category; text representation based on Nave-Bayes has 67.6% MicroF1 of parent- category, 66.5% of sub- category.
