[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] Understandably, the current online property transaction process is quite cumbersome, requiring manual processing. This can easily lead to errors in information or data, necessitating modifications and repeated submissions, which severely impacts the efficiency of online property transactions. Furthermore, the data is often delayed, with the online transaction registration taking several working days to update, affecting users' choices regarding property transactions.

[0033] To address the aforementioned issues, this invention receives online contract signing management requests, identifies the properties and personnel involved in the online contract signing process, collects the property's online contract signing information and the personnel's identity information, and performs information preprocessing and authenticity verification. Upon successful authenticity verification, a contract template is obtained, and the property's online contract signing information and personnel's identity information are filled in and reviewed to generate a property online contract signing agreement. Based on the property online contract signing agreement, identity verification and electronic signature processing are performed for both parties, and the signing time is recorded to generate a valid online contract signing agreement. Based on the valid online contract signing agreement, online contract signing filing materials are generated, uploaded to a preset target filing address for filing processing, and key filing information is generated and publicly disclosed. Real-time collection of construction progress information for the properties involved in the online contract signing process is conducted, management permissions for the personnel's smart mobile devices are obtained, and an online monitoring window is created to monitor and display the construction progress information online. It can automate the entire process of information collection, verification, contract generation, and filing and public disclosure in online housing contract signing, effectively avoiding errors and modifications caused by manual operation, speeding up the online housing contract signing process, improving the efficiency of online housing contract signing, realizing real-time updates of online contract signing and filing, and creating an online supervision window for online supervision and display, making it convenient for users to track and supervise the progress of housing construction.

[0034] Figure 1 A flowchart of the method provided by an embodiment of the present invention is shown.

[0035] Specifically, a comprehensive management method for online contract signing and filing of smart housing construction projects includes the following steps:

[0036] Step S101: Receive the online contract signing management request, identify the online contract signing property and the online contract signing personnel, collect the online contract signing information of the online contract signing property and the personnel identity information of the online contract signing personnel, and perform information preprocessing and authenticity verification judgment.

[0037] In this embodiment of the invention, by receiving a request for online contract signing management and then performing target identification on the request, the system determines the houses and personnel for which smart housing construction online contract signing and filing management is required. It collects the online contract signing information for the houses and the identity information for the personnel. Through content recognition of the online contract signing information and the identity information, key information is extracted to obtain key information about the houses and personnel. This key information is then input into the database, and its authenticity is verified to determine whether the verification is successful.

[0038] Specifically, Figure 2 A flowchart of the online signature management request processing in the method provided by an embodiment of the present invention is shown.

[0039] In a preferred embodiment of the present invention, the steps of receiving the online contract signing management request, identifying the property and personnel involved in the online contract signing, collecting the property's online contract signing information and the personnel's identity information, and performing information preprocessing and authenticity verification specifically include the following steps:

[0040] Step S1011: Receive online contract signing management request;

[0041] Step S1012: Perform target identification on the online contract signing management request to determine the property and personnel involved in the online contract signing;

[0042] Step S1013: Collect the online contract signing information of the houses and the personnel identity information of the online contract signing personnel;

[0043] Step S1014: Extract key information from the online property transaction information and the personnel identity information to obtain key property information and key personnel information;

[0044] Step S1015: Verify the authenticity of the key information about the house and the key information about the personnel, and determine whether the verification is successful.

[0045] In a preferred embodiment of the present invention, verifying the authenticity of the key information about the house and the key information about the personnel, and determining whether the verification passes, specifically includes the following steps:

[0046] Static rules are set according to the format requirements of the property ownership certificate number and the standard rules of the ID card number;

[0047] The fields of key information about the house and key information about the personnel are matched one by one with static rules, and a corresponding basic score is given based on the matching results.

[0048] Obtain target values ​​for house addresses and people's names, and set fuzzy rules with missing field values, homophones, and spelling errors as error ranges;

[0049] Based on fuzzy rules, a character-based fuzzy matching algorithm is used to calculate the similarity scores between all fields in the key information of houses and key information of personnel and the target value.

[0050] Set a similarity threshold, filter the similarity scores based on the similarity threshold, and assign the filtered similarity scores to the corresponding fuzzy scores;

[0051] Key information about the property and key information about the people are submitted to the blockchain node for historical authenticity verification.

[0052] Based on historical authenticity verification, corresponding verification scores are assigned to the relevant key housing information and key personnel information.

[0053] The basic score, fuzzy score, and validation score are combined to obtain the first comprehensive score;

[0054] Set a comprehensive score threshold, and filter the first comprehensive score according to the comprehensive score threshold. The filtering result is the verification result.

[0055] In this embodiment of the invention, a multi-layered verification mechanism, comprising static rule verification, fuzzy matching verification, and blockchain traceability verification, expands the determination of information authenticity from a single dimension to multiple dimensions. Static rule verification addresses the fundamental compliance issues of field formats; fuzzy matching enhances the tolerance for subtle differences in data; and blockchain traceability provides strong support for data integrity and historical authenticity.

[0056] In a preferred embodiment of the present invention, submitting key information about the house and key information about the personnel to a blockchain node for historical authenticity verification specifically includes the following steps:

[0057] All blockchain nodes are divided into multiple levels according to node trustworthiness, and the number of blockchain nodes in different levels is set to increase sequentially according to the level.

[0058] 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;

[0059] By analyzing the verification results of multiple blockchain nodes, the percentage of nodes that successfully verified key information about the house and personnel was obtained out of the total number of nodes, and a consensus result was obtained.

[0060] Set a consensus threshold, filter the consensus results according to the consensus threshold, and obtain the filtered results;

[0061] The filtering results are assigned a score based on the credibility of each blockchain node, resulting in a score for each node.

[0062] Different weights are assigned to blockchain nodes at different levels according to the level, and the node scores of each level are weighted and averaged to obtain the level score.

[0063] The scores from different levels are further aggregated to obtain a second comprehensive score for key housing information and key personnel information;

[0064] The historical authenticity of key information about houses and people is determined based on the second comprehensive score.

[0065] In this embodiment of the invention, by dividing blockchain nodes into multiple layers of a 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 verifications. This layered mechanism improves the system's adaptability to uncertain scenarios. Furthermore, 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 of a single node returning an incorrect result, thus improving the reliability of verification. This consensus mechanism can also adapt to changes in the number of blockchain nodes without requiring significant adjustments to the system logic and can be easily scaled to more verification nodes. By fully utilizing the distributed characteristics of blockchain nodes, the authority and stability of verification are enhanced through layered verification and a multi-point consensus mechanism.

[0066] Furthermore, the intelligent housing construction online contract signing and filing integrated management method also includes the following steps:

[0067] Step S102: When the authenticity verification is passed, obtain the online contract template, fill in and verify the online housing contract information and the personnel identity information, and generate the online housing contract.

[0068] In this embodiment of the invention, after the authenticity verification is passed, a standard online contract template is obtained, and relevant information is extracted from the housing online contract information and personnel identity information according to the content to be filled in the online contract template to obtain the contract requirement information. Then, the contract requirement information is filled in the online contract template to generate a basic online contract, and the basic online contract is sent to relevant reviewers for review feedback. The contract is optimized according to the review feedback to generate a housing online contract.

[0069] Specifically, Figure 3 The flowchart illustrating the method for generating online housing sales contracts provided in this embodiment of the invention is shown.

[0070] In a preferred embodiment of the present invention, the step of obtaining the online contract template and filling in and verifying the housing online contract information and the personnel identity information to generate the housing online contract after the authenticity verification is passed specifically includes the following steps:

[0071] Step S1021: Obtain the online contract template upon successful authenticity verification;

[0072] Step S1022: Extract contract requirement information from the online house registration information and the personnel identity information;

[0073] Step S1023: In the online contract template, the contract requirement information is filled in to generate a basic online contract.

[0074] Step S1024: Review and optimize the basic online contract to generate a housing online contract.

[0075] In a preferred embodiment of the present invention, the process of filling in the contract requirement information in the online contract template to generate a basic online contract specifically includes the following steps:

[0076] Parse the online contract template and extract all placeholders;

[0077] Based on the naming rules for placeholders, the placeholders in the contract template are categorized to obtain the categorization results;

[0078] Based on the classification results, the corresponding fill fields are read from the online housing transaction information and personnel identity information;

[0079] Perform format and integrity validation on the fill fields. After validation, fill the fill fields into the corresponding placeholders to obtain the filled online contract.

[0080] Verify the completed online contract to check for any missing characters;

[0081] If a missing character exists, the first value related to the missing field is retrieved from an external knowledge base;

[0082] Read the context information of the filled-in online contract and obtain the second value by inferring from the context information;

[0083] The first and second values ​​are evaluated based on factors such as source reliability, contextual consistency, logical rationality, and data flexibility to obtain the evaluation results.

[0084] Based on the evaluation results, the first or second value will be selected to fill in the missing characters, resulting in the basic online contract.

[0085] If there are no missing characters, the online contract with the missing characters will be used as the base online contract.

[0086] This 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 of traditional methods requiring high completeness of input data. Alternatively, it can utilize external knowledge bases to complete common field values ​​or default terms.

[0087] Values ​​from external knowledge bases are generally highly reliable, especially when the knowledge base is rigorously validated and comes from authoritative data sources. The reliability of context-inferred values, however, depends on the accuracy and clarity of the context. If the context is complete and logically sound, the inferred value can be very accurate. But if the context is insufficient or semantically ambiguous, the reliability of the inferred value will decrease.

[0088] Because the values ​​in external knowledge bases are generic, they may not perfectly match the specific context of the current contract. For example, the default signing date in the knowledge base may not match the date stipulated in the contract.

[0089] 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 typically a better fit than default values ​​provided by the knowledge base.

[0090] If the missing field involves compliance or explicit business rules (such as the uniqueness of contract number, the authenticity of ID card number, etc.), it is preferable to retrieve it from the knowledge base, because the values ​​in the knowledge base are usually rule-based and more in line with business logic.

[0091] If the missing fields rely more on the specific content and context of the contract, then context inference should be preferred, as context inference values ​​can better reflect the personalized needs of the contract.

[0092] Numerical values ​​obtained from knowledge bases have low flexibility; they are usually fixed or rule-based values ​​and may not be suitable for specific scenarios.

[0093] The values ​​obtained from the context are highly flexible because they are dynamically inferred and can adapt to the specific semantic logic of the contract.

[0094] Therefore, in order to ensure better results, this invention conducts a comprehensive evaluation of characters obtained externally and through inference, and uses this method to fill in missing characters, reducing reliance on user input.

[0095] In a preferred embodiment of the present invention, reading the context information of the filled-in online contract and obtaining the second value based on the inference method of the context information specifically includes the following steps:

[0096] Get the positions of missing characters in the filled-in online contract;

[0097] Based on the position of the missing characters, context fragments of different lengths are dynamically extracted from the filled online contract.

[0098] Using several pre-trained BERT models, we analyze the semantic information of context segments of different lengths to obtain the segment prediction results of missing characters in context segments of different lengths, as well as the corresponding segment confidence scores.

[0099] The global context of the inflated 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.

[0100] The segment confidence scores of several segment prediction results are combined with the global confidence scores of the global prediction results using a weighted evaluation method to obtain several comprehensive confidence scores.

[0101] The prediction results of several segments are compared. When it is determined that the prediction results of several segments are consistent, the consistent result is taken as the candidate value.

[0102] If it is determined that the prediction results of several segments are inconsistent, the segment prediction result corresponding to the highest score in the comprehensive confidence score is selected as the candidate value.

[0103] The candidate values ​​are filtered according to format rules, contextual rules, and domain rules to obtain the second value.

[0104] In this embodiment of the invention, a dynamic context window adjustment mechanism is introduced to flexibly adjust the extraction range based on the information density of missing fields, thereby ensuring that the extracted information is both sufficiently detailed and relevant. This mechanism avoids the problem of too much or too little context. Furthermore, the context is divided into direct context and global context, and semantic analysis is performed separately for each, focusing on both the accuracy of local information and the completeness of global information. This hierarchical processing significantly improves the accuracy and contextual consistency of inference. Multiple models are employed, and by assigning different weights to the inference results of direct and global contexts, the system can more reasonably integrate the information from both. This mechanism improves the credibility of the inference results. When fusing the results of multiple models, results with higher confidence are prioritized and further filtered through logical consistency checks, effectively avoiding the occurrence of unreasonable or low-quality inference results.

[0105] Furthermore, the intelligent housing construction online contract signing and filing integrated management method also includes the following steps:

[0106] Step S103: Based on the online housing contract, verify the identities of both parties and process their electronic signatures, record the signing time, and generate a valid online contract.

[0107] In this embodiment of the invention, identity verification is performed on both parties to the transaction through fingerprint verification, facial recognition, iris recognition, etc., and it is determined whether the verification is successful. If the identity verification is successful, electronic signature processing is performed on both parties to the transaction to obtain the corresponding electronic signature data and record the corresponding signature time. By combining the online housing contract, electronic signature data and signature time, a valid online contract is generated.

[0108] Specifically, Figure 4 The flowchart illustrating the method for generating a valid online contract provided in an embodiment of the present invention is shown.

[0109] In a preferred embodiment of the present invention, the step of verifying the identity of both parties to the transaction and processing their electronic signatures based on the online housing contract, recording the signing time, and generating a valid online contract specifically includes the following steps:

[0114] Furthermore, the intelligent housing construction online contract signing and filing integrated management method also includes the following steps:

[0115] Step S104: Based on the valid online contract, generate online contract filing materials, upload them to the preset target filing address for filing processing, generate key filing information, and publicize the filing.

[0116] In this embodiment of the invention, online contract signing and filing materials are generated based on a valid online contract signing contract, and a target filing address is obtained. The online contract signing and filing materials are then uploaded to the target filing address to achieve automatic filing processing of the online contract signing and filing materials. Furthermore, key information such as the filing number, the building to which the property belongs, the building to which the property belongs, and the address of the property are extracted from the online contract signing and filing materials and organized to generate key filing information.

[0117] Specifically, Figure 5 The flowchart illustrating the generation of online contract signing and filing materials in the method provided by the embodiments of the present invention is shown.

[0122] Step S1044: Extract key information from the online contract signing and filing materials to generate key filing information;

[0123] Step S1045: Publicly disclose the key information for filing.

[0124] Furthermore, the intelligent housing construction online contract signing and filing integrated management method also includes the following steps:

[0125] Step S105: Collect construction progress information of the houses registered online in real time, obtain management permissions of the smart mobile terminal of the person registering the online contract, create an online supervision window, and monitor and display the construction progress information online.

[0126] In this embodiment of the invention, by extracting housing characteristic information such as the housing registration name, housing sales name, and housing developer from the housing online contract signing information, and then collecting the construction progress information of the online contracted housing in real time through multiple preset supervision channels using the housing characteristic information, an authorization request is generated and sent to the smart mobile terminal of the online contract signing personnel. When the online contract signing personnel agree to the authorization request through the smart mobile terminal, they obtain management permissions on the smart mobile terminal. At this time, based on the management permissions, an online supervision window is created in the default browser of the smart mobile terminal. Thus, when the online contract signing personnel have supervision needs, they can monitor and display the construction progress information online through the online supervision window.

[0127] Understandably, multiple regulatory channels may be involved, including the developer's official website, third-party sales websites, etc.

[0128] Specifically, Figure 6 A flowchart of the online monitoring and display process in the method provided by an embodiment of the present invention is shown.

[0129] In a preferred embodiment of the present invention, the real-time collection of construction progress information of the online-signed houses, obtaining management permissions of the smart mobile terminals of the online-signing personnel, creating an online monitoring window, and displaying the construction progress information online specifically includes the following steps:

[0130] Step S1051: Extract house feature information from the online house transaction information;

[0131] Step S1052: In multiple preset monitoring channels, the construction progress information of the online-signed house is collected in real time through the house feature information;

[0139] In this embodiment of the invention, the information collection and processing unit 101 receives online contract signing management requests, then performs target identification on the online contract signing management requests to determine the online contract signing houses and personnel that need to be subject to comprehensive management of smart housing construction online contract signing and filing. It collects the online contract signing information of the online contract signing houses and the personnel identity information of the online contract signing personnel.
