[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] It is understandable that, at present, due to the cumbersome process of online house signing and the need for manual online signing operations, information or data manipulation is prone to occur, resulting in the need for modification and repeated submission, which seriously affects the efficiency of online house signing. In addition, the data has a lag, and it often takes several working days after the completion of the online house signing to complete the update of the online signing record, which affects users' choice of house transactions.

[0021] To solve the above problems, the embodiment of the present invention receives an online signing management request, determines the online signing house and the online signing personnel, collects the online signing information of the online signing house and the personnel identity information of the online signing personnel, and performs information preprocessing and authenticity verification; when the authenticity verification is passed, obtains the online signing contract template, fills in and reviews the online signing information of the house and the personnel identity information, and generates an online signing contract for the house; based on the online signing contract for the house, performs identity authentication and electronic signature processing for both parties to the transaction, and records the signing time to generate a valid online signing contract; based on the valid online signing contract, generates online signing filing materials, uploads them to the preset target filing address for filing processing, generates filing key information, and makes filing announcements; collects the construction progress information of the online signing house in real time, obtains the management authority of the smart mobile terminal of the online signing personnel, creates an online supervision window, and displays the construction progress information online. It can automatically carry out the entire process of information collection, verification, contract generation and filing publicity in the online house signing, effectively avoiding errors and modifications caused by manual operations, speeding up the online house signing process, improving the efficiency of online house signing, and realizing real-time updating of online signing filings. It can also create an online supervision window for online supervision display, making it convenient for users to track and supervise the progress of house construction.

[0022] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0023] Specifically, a smart housing construction and construction house online signing and filing comprehensive management method, the method specifically includes the following steps: Step S101, receiving an online signing management request, determining the online signing house and the online signing personnel, collecting the online signing information of the online signing house and the personal identity information of the online signing personnel, and performing information preprocessing and authenticity verification.

[0024] In an embodiment of the present invention, by receiving an online signing management request and then performing target identification on the online signing management request, the online signing houses and online signing personnel that need to be subject to comprehensive management of smart housing and construction house online signing and filing are determined, the online signing information of the online signing houses is collected, and the personal identity information of the online signing personnel is collected, and content identification is performed on the online signing information of the house and the personal identity information, and then key extraction is performed to obtain the key information of the house and the key information of the personnel, and the key information of the house and the key information of the personnel are input into a database, and the authenticity of the key information of the house and the key information of the personnel is verified to determine whether the verification is passed.

[0025] Specifically, Figure 2 A flow chart of online signing management request processing in the method provided by an embodiment of the present invention is shown.

[0026] Among them, in the preferred implementation mode provided by the present invention, the receiving of the online signing management request, determining the online signing house and the online signing personnel, collecting the online signing information of the online signing house and the personal identity information of the online signing personnel, and performing information preprocessing and authenticity verification judgment specifically include the following steps: Step S1011, receiving an online signing management request; Step S1012, target identification is performed on the online signing management request to determine the online signing house and online signing personnel; Step S1013, collecting the online signing information of the online signing house and the identity information of the online signing personnel; Step S1014, performing key extraction on the house online signing information and the personnel identity information to obtain house key information and personnel key information; Step S1015, verify the authenticity of the house key information and the personnel key information, and determine whether the verification is successful.

[0027] Among them, in the preferred implementation manner provided by the present invention, the authenticity of the key information of the house and the key information of the personnel is verified, and judging whether the verification is passed specifically includes the following steps: Set static rules based on the format requirements of the property ownership certificate number and the standard rules of the ID card number; Match the fields of house key information and personnel key information with static rules one by one, and assign corresponding basic scores based on the matching results; Get the target values ​​of house addresses and people's names, and set fuzzy rules with missing field values, homophones, and spelling errors as error ranges; According to the fuzzy rules, a character-based fuzzy matching algorithm is used to calculate the similarity scores between all fields in the house key information and personnel key information and the target value; A similarity threshold is set, and similarity scores are filtered according to the similarity threshold, and the filtered similarity scores are given corresponding fuzzy scores; Submit key information of the house and key information of the personnel to the blockchain node for historical authenticity verification; According to the historical authenticity verification, the corresponding house key information and personnel key information are given corresponding verification scores; The basic score, the fuzzy score and the verification score are combined to obtain a first comprehensive score; A comprehensive score threshold is set, and the first comprehensive score is filtered according to the comprehensive score threshold, and the filtering result is a verification pass result.

[0028] In the embodiment of the present invention, through the multi-level verification mechanism of static rule verification, fuzzy matching verification and blockchain traceability verification, the judgment of information authenticity is expanded from a single dimension to multiple dimensions. Static rule verification solves the basic compliance problem of field format; fuzzy matching enhances the fault tolerance of subtle differences in data; blockchain traceability provides strong support for data integrity and historical authenticity.

[0029] Among them, in the preferred implementation mode provided by the present invention, submitting the key information of the house and the key information of the personnel to the blockchain node for historical authenticity verification specifically includes the following steps: Divide all blockchain nodes into multiple levels according to node credibility, and set the number of blockchain nodes at different levels in ascending order; The key information of the house and the key information of the personnel are verified step by step through different levels of blockchain nodes in a parallel manner to obtain the verification results; Analyze the verification results of multiple blockchain nodes, obtain the percentage of nodes that successfully verify the key information of the house and the key information of the personnel to the total number of nodes, and obtain the consensus result; Set a consensus threshold, filter the consensus results according to the consensus threshold, and obtain the filtered results; The filtered results are given corresponding scores according to the credibility of each blockchain node to obtain the score of each node; Different weights are set for blockchain nodes at different levels, and the node scores of each level are weighted averaged according to the weights to obtain the level score; The hierarchical scores of different levels are further aggregated to obtain a second comprehensive score of the key information of the house and the key information of the personnel; The historical authenticity of the house key information and personnel key information is judged based on the second comprehensive score.

[0030] In an embodiment of the present invention, by dividing the blockchain nodes into multiple levels of the verification chain and assigning weights to different nodes, it is ensured that the verification results of high-reliability nodes have a greater impact on the score, while low-reliability nodes serve as supplementary verification. This hierarchical mechanism improves the adaptability of the system to uncertain scenarios. In addition, a multi-point consensus mechanism is designed. By analyzing the verification results of multiple blockchain nodes and calculating the consensus ratio, the system avoids the risk that a single node may return an erroneous result, thereby improving the reliability of verification. In addition, this consensus mechanism can adapt to changes in the number of blockchain nodes, without making major adjustments to the system logic, and can be easily expanded to more verification nodes. By making full use of the distributed characteristics of blockchain nodes, the authority and stability of verification are improved through hierarchical verification and multi-point consensus mechanisms.

[0031] Furthermore, the smart housing construction and construction housing online signing and filing comprehensive management method also includes the following steps: Step S102, when the authenticity verification is passed, obtain the online signing contract template, and fill in and review the house online signing information and the personnel identity information to generate the house online signing contract.

[0032] In an embodiment of the present invention, when the authenticity verification is passed, a standard online signing contract template is obtained, and according to the content to be filled in the online signing contract template, relevant extraction is performed from the house online signing information and personnel identity information to obtain the contract requirement information, and then the contract requirement information is filled in the online signing contract template to generate a basic online signing contract, and the basic online signing contract is sent to relevant reviewers for review feedback, and optimized according to the review feedback to generate a house online signing contract.

[0033] Specifically, Figure 3 A flow chart of generating an online house signing contract in the method provided in an embodiment of the present invention is shown.

[0034] Among them, in the preferred implementation mode provided by the present invention, when the authenticity verification is passed, the online contract template is obtained, and the online house signing information and the identity information of the personnel are filled and reviewed, and the generation of the online house signing contract specifically includes the following steps: Step S1021, when the authenticity verification is passed, obtain the online signing contract template; Step S1022, extracting contract requirement information from the house online signing information and the personnel identity information; Step S1023, filling in the contract requirement information in the online contract template to generate a basic online contract; Step S1024, review and optimize the basic online signing contract to generate the house online signing contract.

[0035] Among them, in the preferred implementation mode provided by the present invention, in the online contract template, the contract requirement information is filled in and the generation of the basic online contract specifically includes the following steps: Parse the online contract template and extract all placeholders; According to the naming rules of the placeholders, classify the placeholders in the contract template to obtain the classification results; According to the classification results, read the corresponding fill-in fields from the house online signing information and personnel identity information; Verify the format and integrity of the filled fields. After verification, fill the filled fields into the corresponding placeholders to obtain the filled online contract. Verify the filled online contract to confirm whether there are any missing characters; If there are missing characters, searching the external knowledge base for the first value associated with the missing field; Read the context information of the filled online contract, and obtain the second value by inferring the context information; The first value and the second value are evaluated according to source reliability, context consistency, logical rationality, and data flexibility as evaluation factors to obtain an evaluation result; According to the evaluation results, the first value or the second value is selected to fill in the missing characters to obtain the basic online signing contract; If there are no missing characters, the filled-in online contract will be used as the basic online contract.

[0036] The present invention can intelligently infer field values ​​when data is missing or information is incomplete. For example, it can dynamically infer missing fields based on existing house or personnel information, solving the problem that traditional methods have high requirements for input data integrity. Or it can use external knowledge bases to complete common field values ​​or default terms.

[0037] Generally, the values ​​of external knowledge bases have high reliability, especially when the knowledge base has been strictly verified and comes from an authoritative data source. The reliability of contextual inference values ​​depends on the accuracy and clarity of the context. If the context information is complete and logical, the inferred value may also be very accurate. However, if the context information is insufficient or the semantics are ambiguous, the reliability of the inferred value will be reduced.

[0038] Since the values ​​in the external knowledge base are general, they may not perfectly match the specific scenario of the current contract. For example, the default signing date in the knowledge base may not be consistent with the date agreed in the contract.

[0039] Context-inferred values ​​are derived directly from the contract itself, and are therefore more likely to be semantically and logically consistent with the context. They are usually more consistent than the default values ​​provided by the knowledge base.

[0040] If the missing field involves compliance or clear business rules (such as the uniqueness of the contract number, the authenticity of the ID number, etc.), it is preferred to obtain it from the knowledge base, because the values ​​in the knowledge base are usually regularized and more in line with business logic.

[0041] If the missing fields tend to rely more on the specific content and context of the contract, context inference is preferred because the context inference value can better reflect the personalized needs of the contract.

[0042] The numerical values ​​obtained from the knowledge base have low flexibility and are usually fixed or rule-generated values, which may not be suitable for special scenarios.

[0043] The value obtained from the context has higher flexibility because it is dynamically inferred and can adapt to the special semantic logic of the contract.

[0044] Therefore, in order to ensure better results, the present invention performs a multi-dimensional comprehensive evaluation on the characters obtained externally and inferred, and uses this method to fill in the missing characters to reduce dependence on user input.

[0045] Among them, in the preferred embodiment provided by the present invention, reading the context information of the filled online contract and obtaining the second value by inferring the context information specifically includes the following steps: Get the position of missing characters in the filled online contract; Dynamically extract context fragments of different lengths from the filled online contract according to the position of the missing characters; Use several pre-trained BERT models to analyze the semantic information of context segments of different lengths, obtain the segment prediction results of missing characters in context segments of different lengths, and the corresponding segment confidence scores; The global context of the filled online contract is input into the pre-trained BERT model for semantic analysis to obtain the global prediction result and the corresponding global confidence score; The segment confidence scores of several segment prediction results are respectively combined with the global confidence score of the global prediction result by weighted evaluation to obtain several comprehensive confidence scores; Compare the prediction results of several segments, and when it is determined that the prediction results of several segments are consistent, use the consistent results as candidate values; When it is determined that several segment prediction results are inconsistent, the segment prediction result corresponding to the highest score is selected from the comprehensive confidence score as the candidate value; The candidate values ​​are screened according to the format rule, the context relevance rule and the domain rule to obtain a second value.

[0046] In an embodiment of the present invention, a dynamic context window adjustment mechanism is introduced to flexibly adjust the extraction range according to the information density of the missing field, so as to ensure that the extracted information is both detailed and relevant. This mechanism avoids the problem of too much or too little context. In addition, the context is divided into direct context and global context, and semantic analysis is performed separately, focusing on the accuracy of local information and utilizing the integrity of global information. This hierarchical processing method significantly improves the accuracy of inference and context consistency. In addition, multiple models are adopted, and by assigning different weights to the inference results of direct context and global context, the system can more reasonably integrate the information of the two. This mechanism improves the credibility of the inference results. When fusing the results of multiple models, the results with higher confidence will be given priority, and further screened through logical consistency verification, which effectively avoids the appearance of unreasonable or low-quality inference results.

[0047] Furthermore, the smart housing construction and construction housing online signing and filing comprehensive management method also includes the following steps: Step S103, based on the online house signing contract, identity verification and electronic signature processing are performed on both parties to the transaction, and the signing time is recorded to generate a valid online signing contract.

[0048] In an embodiment of the present invention, identity verification such as fingerprint verification, face recognition, and iris recognition is performed on both parties to the transaction, and it is determined whether the verification is passed. If the identity verification is passed, electronic signatures are processed for both parties to the transaction, the corresponding electronic signature data is obtained, and the corresponding signing time is recorded. By integrating the online housing contract, the electronic signature data, and the signing time, a valid online contract is generated.

[0049] Specifically, Figure 4 A flow chart of generating a valid online signing contract in the method provided by an embodiment of the present invention is shown.

When the online signing personnel agrees to the authority application through the smart mobile terminal, the management authority of the smart mobile terminal is obtained. At this time, based on the management authority, an online supervision window is created in the default browser of the smart mobile terminal, and then when the online signing personnel has supervision needs, the construction progress information can be displayed online through the online supervision window.

[0057] It is understandable that multiple regulatory channels may include the developer’s official website, third-party sales websites, etc.
