Types And Selection Of The Integration Patterns Of Deep Web Information Resource

Firstly, this paper introduces the origin of the integration patterns of deep web information resources and the significance of this research, then summarizes the research status at home and abroad, next introduces the concept of deep web, the causes of deep web and the types of deep web, analyzes the use value of the deep web information resources.This paper introduces six integration patterns of deep web information resources. They are the integration patterns based on web categories, the integration patterns based on a unified query interface, the integration patterns based on deep web surfacing by common search engine, the integration patterns based on OAI-PMH protocol, the integration patterns based on local data warehouse and the integration patterns based on open search platform.And introduce each integration pattern's implementation process and the practice results. Analysis the common problems when these integration patterns in the process of concrete implementation, and on this base we give some possible solutions. Then analysis the advantages and disadvantages of each integration pattern, and according to certain integrated principle choose suitable integration patterns for different integrated subjects. In the end of this article we talk about the future work of the integration on deep web information resources, it contains the work of guarantee data source's quality, the work of cooperate with the owner which has the network database,the work of develop a more intelligent web crawler and the work of evaluate the deep web information resources integration system.
