Transportation Information Resource Sharing Method Based On Resource Catalog

With the deepening of the informatization process of the transportation industry and the continuous improvement of e-government system construction requirements,the problem of "information islands" caused by system heterogeneity and data isolation has become more and more complex,which seriously hinders the sharing of data across levels and departments work.Existing data sharing methods have the problems of high manual dependence and low efficiency.This paper conforms to the construction requirements of the resource catalog proposed by the national e-government,and researches and designs a data sharing method based on the resource catalog.The main work of the paper is as follows:First of all,the paper takes the transportation industry information resource catalog released by each province and government website data as the main data sources,formulates labeling specifications and performs sequence labeling,and uses the named entity recognition method based on ALBERT-Bi GRU-CRF model to realize the automatic recognition of three types of named entities: "general data","important data" and "core data",forming a hierarchical corpus of transportation data.Further,the TF-IDF algorithm is used to extract keywords from the text and the Word2 Vec model is used for word vector representation.By calculating the similarity between the keywords and the target data,a grading of the target data is achieved.Secondly,a data sharing permission control model based on resource catalog is designed and implemented.Through the refinement of the sharing range attributes in the resource catalog,a clear description of the sharing range is formed,and a resource sharing range retrieval algorithm based on the organization’s unified social credit code is proposed.On this paper,combining data permissions and functional permissions,a fine-grained data permission model based on organizational structure is designed.Further combining the data classification results with the authority control model,the process of data sharing based on the resource catalog is designed.The high efficiency of the data sharing process proposed in this paper is verified through simulation experiments.Finally,the data sharing platform of transportation industry based on resource catalog is designed and implemented.The implementation framework,technical ideas and core module functions.Meanwhile,the functionality of each core module is tested to verify the feasibility and effectiveness of the data sharing technology proposed in this paper.
