Design of Archives Retrieval Scheme for Power Transmission and Transformation Engineering Considering Semantic Information

With the development of power transmission and transformation engineering construction, the volume of unstructured documents with multi-source heterogeneity throughout the entire process is increasing, and stable management of these unstructured documents is needed. In order to achieve efficient retrieval of unstructured documents in power transmission and transformation engineering, this paper designs a full text retrieval scheme for power transmission and transformation engineering archives that takes into account semantic information. Constructing a specialized terminology dictionary for power grid to assist in optimizing intelligent word segmentation. Extracting feature information from power transmission and transformation engineering data that used to assign semantic values to Chinese word segmentation results, and improving segmentation algorithm based on semantic labels that improve the efficiency and accuracy of full-text retrieval. Finally, this article calculates efficiency of full-text retrieval of power transmission and transformation engineering, and verifies the feasibility of the proposed technical scheme.
