In particular, through machine learning and deep learning models, key information can be automatically extracted from large amounts of documents, structured data can be generated, and retrieval and management processes can be optimized.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0042] Example 1, with reference to Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a document management method based on big data analysis, including the following steps:

[0043] S1. Collect document data and preprocess it to generate words. Map syntactic coordinates and semantic heat values ​​to a two-dimensional space to construct a semantic heat field. Use numerical differentiation methods to calculate the gradient modulus of the semantic heat field. Define each word as a particle and calculate the displacement modulus of the updated word position. Based on the gradient modulus and displacement modulus, use weighted linear combination to calculate the conflict score. Filter the conflict scores that are greater than the score threshold to obtain the conflict words.

[0044] Specifically, document data is collected and preprocessed to generate words, including:

[0045] Use the APL interface to collect document data from cloud storage services, use document parsing to extract text from the document data to obtain text sentences, use natural language processing to segment the text sentences, and perform text cleaning on the segmentation results (use regular expressions to remove numbers, extra spaces, line breaks, and punctuation in the text, use the stop word list provided by NLTK to remove common meaningless words, and perform standard processing) to generate words.

[0046] By removing redundant information such as unnecessary symbols, numbers, spaces, and stop words, the efficiency and accuracy of subsequent text analysis can be significantly improved. Using pre-trained natural language processing models for standardized processing ensures consistency between documents from different sources, providing an accurate text basis for subsequent semantic analysis.

[0047] Furthermore, a weighted linear combination is used to calculate the conflict score, and conflict scores greater than the score threshold are filtered to obtain conflict words, including:

[0048] Use the pre-trained BERT model to encode words, generate semantic vectors for each word and perform normalization. Use dependency parsing to parse the text sentences containing the words, generate a dependency syntax tree, assign syntactic coordinates to each word, and obtain the position vector of each word.

[0049] The cosine function is used to calculate the cosine similarity. Based on the cosine similarity, the TF-IDF weighted semantic distance method is used to calculate the semantic heat value of each word. The formula is:

[0054] Map the syntactic coordinates and semantic heat values ​​into two-dimensional space to construct the semantic heat field. The formula is:

[0061] Define each word as a particle, and calculate the initial velocity vector of each particle based on the normalized semantic vector. The formula is:

[0069] PCA is used to extract the maximum eigenvector of the semantic field tensor, which is defined as the flow field velocity direction vector. The initial velocity vector and the flow field velocity direction vector are superimposed to obtain the final velocity of the particle. The formula is:

[0070] ,

[0071] in is the final velocity of the pth particle, is the velocity direction vector of the p-th particle;

[0072] Use the final velocity of the particle to update the word position and calculate the displacement modulus of the updated word position. The formula is:

[0073] ,

[0074] ,

[0075] in is the updated particle position of the i-th particle at time t+1, is the displacement modulus of the i-th particle at time t+1;

[0076] Based on the gradient modulus and displacement modulus, a weighted linear combination is used to calculate the conflict score, which is:

[0077] ,

[0078] in For a two-dimensional plane The conflict score at and are the weights of the weighted linear combination (set using web search);

[0079] The percentile method is used to set the scoring threshold, and conflicting words with scores greater than the scoring threshold are filtered to obtain conflicting words.

[0080] The BERT model can capture the deep semantic information of words, overcoming the limitations of traditional rule-based word segmentation methods. This allows words in documents to not only rely on their surface meaning but also reflect the semantics of the context. Dependency parsing provides a structured representation of the grammatical relationships between words, allowing the system to simultaneously consider the grammatical connections between words when analyzing documents. By combining semantic vectors and syntactic coordinates, it not only analyzes the independent semantics of vocabulary but also reveals the relationships between words and their importance in the document. Particle swarm optimization simulates the laws of particle interaction in nature by dynamically adjusting the positions of words, effectively optimizing the semantic relationships in documents. By calculating the gradient modulus and displacement modulus of the semantic thermal field, the present invention can identify potential conflicting words in documents and effectively process them. The LIF model simulates the discharge process of neurons. Its advantage is that it can make real-time dynamic adjustments based on the semantics and contextual information of conflicting words, avoiding the problem of information misunderstanding or loss caused by conflicting words in traditional document management and improving the accuracy and relevance of documents.

[0081] S2. Assign a LIF neuron to each conflicting word, use the LIF model to update the membrane potential of each neuron, screen the membrane potential greater than the trigger threshold, mark it as a high-conflict word, calculate the turbulence dissipation rate of the high-conflict word, calculate the priority and fitness of the candidate words, sort the candidate word set of each high-conflict word in descending order according to fitness, and select the candidate word with the highest fitness to replace it;

[0082] Specifically, membrane potentials greater than the trigger threshold are screened and marked as high-conflict words, including:

[0083] Assign a LIF neuron to each conflict word, initialize the membrane potential to 0, and calculate the current of each neuron. The formula is:

[0084] ,

[0085] in At time t, The current of a neuron, For the The context window of neurons (based on conflict word statistics), and Respectively and The semantic vector of and Respectively and The position vector of

[0086] The membrane potential of each neuron is updated using the LIF model, as follows:

[0087] ,

[0088] in is the time constant (set using the empirical setting method) that controls the membrane potential decay rate, At time t, The membrane potential of each neuron;

[0089] Use the Euler method to solve and obtain the membrane potential of each neuron. The formula is:

[0090] ,

[0091] in is the time step (set using stability analysis);

[0092] The trigger threshold was set using the statistical distribution method, and membrane potentials greater than the trigger threshold were screened and marked as high-conflict words.

[0093] The LIF neuron model can simulate the biopotential change process of neurons. Its membrane potential gradually changes with the passage of time and the influence of external current. By mapping each conflicting word to an independent neuron, the processing of conflicting words can be controlled more fine-grainedly. The membrane potential update process can reflect the influence that the conflicting words gradually generate in the document. This dynamic process improves the flexibility and accuracy of conflicting word recognition. The calculated results of the membrane potential provide a basis for further conflicting word screening. By real-time updating of the membrane potential of each neuron, the system can dynamically identify high-conflict words in the document and effectively mark them. The trigger threshold of the membrane potential can be dynamically adjusted according to the context of different documents, allowing the system to flexibly respond to different types of document content.

[0094] Furthermore, the candidates are sorted in descending order according to fitness, and the highest candidate words are selected for replacement, including:

[0095] Collect candidate words from the industry vocabulary, use the pre-trained Word2Vec model to convert the candidate words into candidate vectors, use the k-selection method to filter them, and perform normalization to obtain a candidate word set;

[0096] Calculate the turbulence dissipation rate of high-conflict words using the formula:

[0097] ,

[0098] in For the The turbulent dissipation rate of high-conflict words, For the context windows of high-conflict words, based on syntactic coordinate distance, and Respectively and The final speed of high-conflict words, and Respectively and Position vectors of high-conflict words, is the regularization constant, prevent it from being 0;

[0099] Based on the candidate word set, the priority and fitness of the candidate words are calculated using the following formula:

[0100] ,

[0101] ,

[0102] ,

[0103] in For the The context vectors of high-conflict words, is the priority of the qth candidate word, is the normalized candidate vector of the qth candidate word, is the fitness of the qth candidate word;

[0104] For each high-conflict word candidate set, sort them in descending order according to fitness, and select the highest candidate word for replacement.

[0105] By combining the industry vocabulary and deep semantic analysis of the Word2Vec model, multiple suitable alternative words can be provided for each conflicting word, thereby ensuring effective replacement while ensuring semantic consistency, avoiding the context distortion caused by the fixed replacement of a single word. The priority sorting of conflicting words can be further refined through the turbulent dissipation rate, making the conflicting word replacement process more efficient and accurate. The calculation of fitness can take into account multi-dimensional semantic information, including context windows, grammatical structures and position vectors, making the replacement process more refined and intelligent, and the semantic relevance and fluency of the replaced words effectively avoid the semantic deviation caused by improper word replacement.

[0106] S3. Build a visual interface to display the replacement results and store the document data collected and analyzed.

[0107] Specifically, a visual interface is built to display the replacement results, including:

[0108] Build a visual interface to display the replacement results, allowing users who have passed real-name verification to view them.

[0109] The visual interface makes word replacement in documents more intuitive. Users can clearly see which words are replaced and what the new words are, thereby enhancing their trust in the system processing results. Real-name verification ensures that only authorized users can view and modify documents, thereby effectively preventing unauthorized operations and avoiding data leakage or malicious tampering.

[0110] Furthermore, the document data generated by the collection and analysis is stored, including:

[0111] The collected RGB images and the detection results generated by the analysis are stored in the central database, and security access measures are set. The central database will back up the stored data to the cloud and regularly perform integrity checks on the stored data and backup data. After the test is completed, the integrity test record will be generated and stored synchronously in the central database.

[0112] By recording and synchronizing each test result to a central database, data reliability and traceability are further ensured. Through cloud backup, all document data and replacement results can be stored in a distributed cloud environment, greatly reducing the risk of data loss. By regularly performing data integrity checks, the system can automatically detect any damage or tampering with the data, and repair or update it in a timely manner to ensure the consistency of backup data with the original data, thereby enhancing the reliability and security of data management.

[0113] This embodiment also provides a document management system based on big data analysis, including:
