Research and Design on E-government Information Retrieval Model

Abstract

At present, most government websites have not given full play to the internet's characteristic such as share, interaction. The public satisfaction is poor. Therefore, this article puts forward an e-government information retrieval model based on the metadata. Firstly it builds an e-government information resource database, and all kinds of different types of resources are uniformly stored in the resource database; Secondly, the resources are described by metadata, and e-government information resources metadata scheme is designed; Thirdly, the metadata extraction algorithm is designed to extract the metadata elements of e-government information resources; Finally, e-government information resources storage and retrieval schemes are designed. The experiment result shows that the information retrieval method based on metadata can improve the e-government information retrieval efficiency and precision, and realizes the share of e-government resources. Thus it is a practical approach for the task of e-government information retrieval.
