[0057] Furthermore, the present invention enables different categories of information to be clearly classified and managed by analyzing information classification requirements and determining railway engineering information classification standards, thereby improving the efficiency of information organization and management; the present invention can more accurately understand the importance of various types of information to railway engineering projects by evaluating the importance of railway engineering information categories, providing a more scientific basis for decision-making; the present invention determines the security level of various types of information by evaluating the importance of information categories, which helps to reasonably formulate information security strategies and measures and improve information security; the present invention formulates corresponding encryption strategies and storage locations according to the security level of information categories to ensure the confidentiality and integrity of information; the present invention standardizes the management of railway engineering information through classified encrypted storage management, thereby improving the scientificity and standardization of information management; through the above measures, the present invention improves the security protection effect of railway engineering information, reduces the risk of information leakage and damage, and helps to ensure the smooth progress of railway engineering projects.

[0058] In an embodiment of the present application, a railway engineering information management method is provided, wherein the classification standard of information is obtained, and the classification standard is analyzed to determine the classification rule of the railway engineering information, including: obtaining the classification standard of information, and splitting the classification standard into multiple classification rule indicators; judging whether each classification rule indicator can classify all railway engineering information, and selecting the classification rule indicators that can classify all railway engineering information as candidate classification rules; determining the number of types that each candidate classification rule classifies all railway engineering information, and determining the candidate classification rule with the largest number of types as the classification rule for the railway engineering information.

[0059] Specifically, the classification standard of information is obtained, and the classification standard is split into multiple classification rule indicators; it is determined whether each classification rule indicator can classify all railway engineering information; after determining the number of types that each candidate classification rule classifies all railway engineering information, the candidate classification rule with the largest number of types is selected as the classification rule of the railway engineering information. Through the above method, the classification rules of railway engineering information can be scientifically and systematically determined so as to effectively manage and classify information, which is helpful to improve the scientificity and efficiency of railway engineering information management and provide a scientific basis for the smooth progress and decision-making of railway engineering projects.

[0060] In an embodiment of the present application, a railway engineering information management method is provided, wherein the railway engineering information is classified based on a classification rule, and the railway engineering information is divided into multiple railway engineering information categories, including: the railway engineering information is divided separately according to the classification rule to obtain a plurality of initial railway engineering information categories, and it is determined whether there is an intersection between each initial railway engineering information category; if there is an intersection between each initial railway engineering information category, the title of the railway engineering information in the intersection is determined, the strength of conformity between the title of the railway engineering information and each initial railway engineering information category is analyzed, and the initial railway engineering information category with the highest strength of conformity is used as the railway engineering information category where the railway engineering information is located; if there is no intersection between each initial railway engineering information category, each initial railway engineering information category is directly used as the railway engineering information category.

[0061] Specifically, for each initial railway engineering information category, an intersection analysis is required to determine whether there is common information between them. If there is an intersection, we need to further analyze the title and content of the railway engineering information in the intersection; for the railway engineering information in the intersection, its title needs to be extracted, and for each railway engineering information title in the intersection, it is compared with each initial railway engineering information category to analyze its compliance strength with each category; according to the analysis results of the compliance strength, the initial railway engineering information category with the highest compliance strength is selected as the final railway engineering information category; if each initial railway engineering information category does not have an intersection, then each initial railway engineering information category is directly used as the final railway engineering information category. Through the above steps, the final railway engineering information category can be scientifically determined based on the title, content and classification rules of the railway engineering information, so as to manage and classify the information more finely and accurately, which helps to improve the scientificity and accuracy of railway engineering information management and provide effective support for the information management of railway engineering projects.

[0062] In an embodiment of the present application, a railway engineering information management method is provided, wherein the analysis of the conformity strength between the title of the railway engineering information and each initial railway engineering information category includes: respectively determining the semantic meaning of the title of each railway engineering information and each initial railway engineering information category, and converting the semantic meaning corresponding to the railway engineering information title and the semantic meaning corresponding to the initial railway engineering information category into a vector; respectively calculating the cosine similarity between the semantic meaning vector of the railway engineering information title and the semantic meaning vector of each initial railway engineering information category, and determining the calculation result as the conformity strength between the title of the railway engineering information and each initial railway engineering information category.

[0063] Specifically, a natural language processing model is used to represent the semantics of each railway engineering information title and the initial railway engineering information category, which can be achieved through word embedding, sentence vector or other methods; the semantic meaning corresponding to the railway engineering information title and the semantic meaning corresponding to the initial railway engineering information category are converted into vectors, and the vector representation of each text is obtained by using a pre-trained natural language processing model (such as BERT, GPT, etc.); for the semantic meaning vector of each railway engineering information title, the cosine similarity between it and the semantic meaning vector of each initial railway engineering information category is calculated. Cosine similarity is a commonly used method to measure the degree of consistency between the directions of two vectors and can be used to measure semantic similarity; the calculation result is determined as the consistency strength of the railway engineering information title and each initial railway engineering information category, and the consistency strength of each railway engineering information title and the initial category can be determined by comparing the size of the cosine similarity; according to the calculation result, the initial railway engineering information category with the highest consistency strength is selected as the final railway engineering information category, and a higher cosine similarity indicates that the semantic similarity between the title and the category is higher, which means that the title is more consistent with the semantic characteristics of the category. The above steps quantitatively measure the semantic similarity between each railway engineering information title and the initial category by utilizing the semantic representation ability of the natural language processing model, so as to more objectively determine the final railway engineering information category.

[0064] In an embodiment of the present application, a railway engineering information management method is provided, wherein the railway engineering information corresponding to the railway engineering information category is analyzed to determine the key information features that affect the importance of the railway engineering information category, including: obtaining the railway engineering information corresponding to the railway engineering information category, and determining the text content of the railway engineering information; extracting keywords and text themes from the text content, and determining the semantic meanings of the keywords, and determining the keywords with semantic meanings related to the text themes as the key information features that affect the importance of the railway engineering information category.

[0065] Specifically, the text content of the railway engineering information is obtained, and the keywords and themes in the text content of the railway engineering information are extracted using natural language processing tools or keyword extraction algorithms; for the extracted keywords, their semantic meanings are obtained; the keywords with semantic meanings related to the text theme are determined as key information features that affect the importance of the railway engineering information category. These key information features can help understand the theme and content of the railway engineering information, so as to make a more accurate judgment on the category to which it belongs. Through the above steps, keywords can be extracted from the railway engineering information text, the semantic meanings of these keywords can be understood, and the keywords related to the text theme can be determined as key information features that affect the importance of the railway engineering information category. These key information features can help better understand the railway engineering information, so as to provide more useful information for information classification and analysis.

[0066] In an embodiment of the present application, a railway engineering information management method is provided, wherein the importance of railway engineering information categories is evaluated based on key information features to obtain importance evaluation values ​​of railway engineering information categories, including: acquiring key information features and text topics, and calculating the correlation between each key information feature and the text topic; performing importance evaluation on the correlation between each key information feature and the text topic to obtain an importance evaluation value of each key information feature; pre-setting a weight for each key information feature, and performing weighted addition calculation on the importance evaluation value of each key information feature and the preset weight to obtain the importance evaluation value of the railway engineering information category.

[0067] Specifically, key information features and text topics are obtained. For each key information feature and text topic, the correlation calculation method of word frequency statistics can be used to calculate the correlation between them; according to the calculated correlation, each key information feature is evaluated for importance. A higher correlation usually indicates that the feature is more closely related to the text topic, so its importance evaluation value will be higher; the weight of each key information feature is pre-set, and the importance evaluation value of each key information feature is weighted and added with the preset weight to obtain the importance evaluation value of the railway engineering information category. Through weighted addition calculation, the importance evaluation value of each railway engineering information category can be obtained. These evaluation values ​​represent the importance of each category in the text, and more accurate classification and analysis can be performed. A higher importance evaluation value indicates that the category is more important in the text, and vice versa, which helps to identify the key topics and features in the railway engineering information and to have a deeper understanding and analysis of the information. Through the above steps, the correlation, importance evaluation value and preset weight between the key information features and the text topic can be comprehensively considered to obtain the importance evaluation value of the railway engineering information category, providing strong support for further information processing and analysis.

[0068] In an embodiment of the present application, a railway engineering information management method is provided, wherein the security level of a railway engineering information category is determined according to an importance evaluation value, comprising: presetting a security level-importance evaluation value interval correspondence, wherein the security level-importance evaluation value interval is associated with a corresponding security level for each importance evaluation value interval; determining the importance evaluation value of the railway engineering information category, and based on a mapping relationship between the importance evaluation value interval to which the importance evaluation value belongs within the security level-importance evaluation value interval correspondence, selecting the security level corresponding to the importance evaluation value interval as the security level of the railway engineering information category.

[0069] Specifically, the corresponding relationship between the security level and the importance evaluation value interval is defined. For example, the importance evaluation value can be divided into several intervals, and then the corresponding security level is specified for each interval; the importance evaluation value of the railway engineering information category is calculated according to the previous steps, and based on the mapping relationship between the importance evaluation value interval to which the importance evaluation value belongs in the security level-importance evaluation value interval correspondence relationship, the security level corresponding to the importance evaluation value interval is selected as the security level of the railway engineering information category; according to the mapping relationship, the security level of the railway engineering information category is determined. Through this process, the importance evaluation value of the railway engineering information category can be mapped to the pre-set security level-importance evaluation value interval correspondence relationship according to the importance evaluation value of the railway engineering information category, thereby determining the security level of the railway engineering information category, which is helpful for better management and decision-making of railway engineering information, provides a basis for information security management, and ensures the reasonable evaluation and processing of railway engineering information.

[0070] In an embodiment of the present application, a railway engineering information management method is provided, wherein the encryption strategy and storage location of the railway engineering information category are determined according to the security level, including: judging the security level corresponding to the railway engineering information category, and setting the encryption strategy and storage location of the railway engineering information category according to the judgment result; for the railway engineering information category with a security level lower than the preset level, setting a password-based encryption algorithm to encrypt the railway engineering information category, and storing the encrypted railway engineering information category in a general area; for the railway engineering information category with a security level higher than or equal to the preset level, setting a strong encryption algorithm to encrypt the railway engineering information category, and storing the encrypted railway engineering information category in a core area.

[0071] Specifically, for railway engineering information categories with high security levels, complex encryption strategies should be adopted, such as using strong encryption algorithms (such as AES-256) to encrypt information. At the same time, multi-factor authentication may be required to control access rights to information. Encrypted railway engineering information categories that are higher than or equal to the preset level should be stored in the core area, which is a highly secure and controlled database or file system that can only be accessed by strictly authorized personnel; for railway engineering information categories with lower security levels, relatively simple encryption strategies can be adopted, such as password-based encryption algorithms (such as AES-128) to ensure the security of information during transmission and storage. Encrypted railway engineering information categories that are lower than the preset level can be stored in the general area, which may be a general database or file system, and basic access control and permission management need to be ensured. By setting different encryption strategies and storage locations, the security of railway engineering information can be protected, and the information can be reasonably managed and stored according to its security level; information with a security level higher than or equal to the preset level adopts stricter encryption and storage strategies to ensure its high confidentiality and security; while information with a security level lower than the preset level adopts relatively simple encryption and storage strategies to meet basic security needs. Through these measures, railway engineering information can be better managed and protected, its security and confidentiality can be ensured, and encryption and storage strategies can be reasonably formulated according to its importance.
