Due to the characteristics of multi-source heterogeneity of party history information resources, the organisation and storage of party history information resources remain in the digital stage at this stage. In order to achieve the transformation of important party history information resources in the new democratic period from digitalisation to intellectualisation, this paper collects and preprocesses the relevant information data of important party history in the new democratic period in the historical materials. The entity knowledge model in the knowledge graph is constructed by combining the characteristics of important party history with the data, encoding and processing the nodes and timestamps in the important party history by using encoders, learning its evolution characteristics, and realising the complementary processing of the time sequence of important party history. Finally, we construct a narrative system of important party history from the new democratic period based on historical materials. The study shows that there are 2015 keywords of important party history during the New Democracy period in the historical materials, and there are 36 keywords with frequency values of 3 times or more. It is also found that the system can accurately narrate important party history events in the New Democratic Period and can allow users to learn about other important party history figures or events that are closely related to them when searching for important party history-related information. This paper responds to the call for promoting the popularisation of Party history for all people, and the visual and vivid display of important Party history events through the form of knowledge mapping can improve the public’s understanding and knowledge of Party history events.

Three-dimensional geological modeling can visually display and express complex geological bodies, which is conducive to showing the internal morphological characteristics of geological bodies and facilitating mine management and geological research. Taking an iron deposit as the research object, the relevant geological data in the region are collated and collected, and the data of the geological exploration line and drilling data of the production exploration line are processed by information technology. Based on the three-dimensional mining modeling software Surpac, the geological database, geological entity model and roadway model of the mining area are established. At the same time, the orebody model is established to provide the basis for delineating the effective mining boundary, and the local orebody model is established according to the model and the production exploration line data to compare and update the model. The establishment of the overall geological model provides technical support for the production and exploration process and provides guidance for the mining plan of the mine. [ABSTRACT FROM AUTHOR]

Using BIM for route selection design of urban rail transit based on GIS information is the inevitable product in the development of intelligent transportation. In order to realize route forward design based on BIM+GIS, this paper analyzes the forward design's characteristics of urban rail transit. Firstly, a structured data standard of three-dimensional environment model is proposed and the structure tree is formed. Based on the Openrail, a BIM route selection design platform compatible with multi-source data is developed to generate a standardized and structured three-dimensional environment entity model. Combined with geographic information model, route design tools are developed. Finally, the scheme's conceptual models are quickly generated based on route design results, and structured data are used to assist scheme decision. The research results show that the BIM route selection design platform can be compatible with a variety of data formats in BIM and GIS models, which meet the requirements of forward design of route selection. Standardized data can realize data sharing and improve the value of model data. BIM forward design can greatly improve the design efficiency and quality. [ABSTRACT FROM AUTHOR]
