[0035] The method embodiment provided in Embodiment 1 of this application can be executed on a mobile terminal, computer terminal, or similar computing device. Figure 1 A hardware structure block diagram of a computer terminal (or mobile device) for implementing an information retrieval method is shown. Figure 1As shown, the computer terminal 10 (or mobile device) may include one or more processors 102 (shown as 102a, 102b, ..., 102n in the figure) 102 (processor 102 may include, but is not limited to, a microprocessor (MCU) or a field-programmable gate array (FPGA), etc.), a memory 104 for storing data, and a transmission device 106 for communication functions. In addition, it may also include: a display, an input / output (I / O) interface, a Universal Serial Bus (USB) port (which may be included as one of the ports of a BUS bus), a network interface, a power supply, and / or a camera.

For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.
[0036] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof.

[0039] The display can be, for example, a touchscreen liquid crystal display (LCD), which allows the user to interact with the user interface of the computer terminal 10 (or mobile device).
[0040] Under the aforementioned operating environment, this application provides the following: Figure 2 The information retrieval method shown. Figure 2 This is a flowchart of the information retrieval method according to Embodiment 1 of this application.
[0041] Step S201: Upon receiving a retrieval request for bidding information, determine whether the retrieval request includes retrieval information for the target retrieval dimension.
[0042] Optionally, electronic devices, application systems, servers, or other similar devices can be used as the executing entity of this application. In this embodiment, the target processing system is used as the executing entity to execute the information retrieval method described above.
[0043] Optionally, a request to retrieve bidding information refers to a user's request to the system to find specific bidding information. For example, a user might ask, "What are some recent bidding announcements for 'competitive storage'?"
[0044] When retrieving bidding information, multiple search dimensions may be involved. These dimensions might include: bidding field (e.g., finance, construction), business type (e.g., account opening, deposit), business keywords, bidding region, issuing entity, and publication time. Target search dimensions are the key search dimensions pre-defined by the administrator of the target processing system. When a search request lacks information corresponding to a target search dimension, it indicates that the search request is missing key information. For example, target search dimensions could be business type and bidding region.
[0045] In an optional embodiment, upon receiving a search request, the target processing system can utilize a search dimension recognition model to parse the text content of the user's search request to identify whether it contains search information for the target search dimension. The search dimension recognition model can be trained based on a training sample set, where the training samples are sample search requests, and the true labels of the training samples represent the search dimensions included in the sample search requests. Therefore, based on the model's recognition results, it is determined whether the search request includes search information for the target search dimension.
[0046] In another optional embodiment, the target processing system can extract keywords from the search request and determine the search dimension to which each keyword belongs based on a preset mapping table (containing the correspondence between words and search dimensions) or natural language processing technology, so as to determine whether the search request includes search information of the target search dimension.
[0047] Step S202: If the search request does not include search information for the target search dimension, a prompt message is generated, wherein the prompt message is used to suggest supplementary search information.
[0048] When the system identifies that a search request lacks a specific search dimension (i.e., the target search dimension), it can generate a prompt message based on the missing target search dimension. For example, if the missing target search dimension in the search request is the bidding region, the prompt message could be "Please provide the bidding region" to help the user complete the search. Or, if the missing target search dimension in the search request is the bidding business type, the prompt message could be "Please provide the bidding business type, such as account opening business, deposit business, etc."
[0049] In an optional embodiment, if there are multiple target search dimensions, the system will generate a prompt message if any target search dimension is missing in the search request. After generating the prompt message, the prompt message will be sent back to the user, that is, to the initiator of the search request for the bidding information.
[0050] In an optional embodiment, if the search request includes search information for all target search dimensions, it is determined that the search information entered by the user is complete, and thus the bidding information is retrieved directly according to the user's search request to obtain the search results.
[0051] Step S203: Upon receiving the retrieval information for the target retrieval dimension, retrieve the bidding information based on the retrieval information and retrieval request to obtain the retrieval results.
[0052] Optionally, after receiving the prompt, the user supplements their search information based on the prompt and sends the supplemented information back to the target processing system. Upon receiving the search information for the target search dimension from the user, the target processing system determines that the user has provided complete search information. It then retrieves the bidding information based on the supplemented search information and the original search information in the search request, thus obtaining the search results.
[0053] In an optional embodiment, the search results include at least one tender information, which may be a tender document, a tender notice, or other information related to tendering.
[0054] In an optional embodiment, the search results may also include bidding information and structured information of the bidding information, such as key fields such as the bidding entity, title, brief description, time, and source website of the bidding information.
[0055] In an optional embodiment, when the target processing system receives the retrieval information of the target retrieval dimensions provided by the user, it can determine whether the target retrieval dimensions provided by the user are complete. If the target retrieval dimensions are still missing, it can continue to generate prompts to prompt the user to supplement the retrieval information until it is determined that the user has provided retrieval information of all target retrieval dimensions. Then, it retrieves the bidding information based on the retrieval information and the retrieval request to obtain the retrieval results.
[0056] In this embodiment, upon receiving a retrieval request for bidding information, the system determines whether the retrieval request includes retrieval information for the target retrieval dimension. This enables the detection of the completeness of the retrieval conditions in the bidding request. If the retrieval request does not include retrieval information for the target retrieval dimension, a prompt message is generated. This allows the user to supplement relevant information when the retrieval conditions lack key information, so that the retrieval can be performed based on the complete retrieval information after the information is supplemented. This avoids meaningless data retrieval when the retrieval information provided by the user lacks key content, effectively improving the accuracy and efficiency of retrieving bidding information.
[0057] Therefore, the method provided in this application achieves the goal of retrieving bidding information based on complete search information, realizes the technical effect of improving the accuracy of retrieving bidding information, and solves the technical problem of low accuracy in retrieving bidding information in related technologies.
[0058] Optionally, in the information retrieval method provided in this application embodiment, determining whether the retrieval request includes retrieval information of the target retrieval dimension includes: extracting keywords from the retrieval request and determining the retrieval dimension to which each keyword belongs; determining whether the retrieval dimensions to which all keywords belong include the target retrieval dimension; if the retrieval dimensions to which all keywords belong include the target retrieval dimension, determining that the retrieval request includes retrieval information of the target retrieval dimension; if the retrieval dimensions to which all keywords belong do not include the target retrieval dimension, determining that the retrieval request does not include retrieval information of the target retrieval dimension.
[0059] Optionally, the target processing system can utilize natural language processing techniques, such as part-of-speech tagging and named entity recognition, to identify and extract keywords from the user's search request text. Within the target processing system, a mapping table between keywords and search dimensions can be designed and maintained. The search dimension to which each keyword belongs is determined by looking up the mapping table. For example, "competitive storage" might map to "business type," and "Shanghai" might map to "bidding region." Alternatively, a search type classification model can be used to process keywords to determine the probability that a keyword belongs to each search dimension, and then the search dimension to which the keyword belongs can be determined based on the probability value. The search type classification model can be a pre-trained neural network model.
[0060] After obtaining the search dimensions to which all keywords belong in the search request, it is determined whether the search dimensions to which all keywords belong include the target search dimension. If the search dimensions to which all keywords belong include a target search dimension, then it is determined that the search request includes search information for that target search dimension; if the search dimensions to which all keywords belong do not include a target search dimension, then it is determined that the search request does not include search information for that target search dimension.
[0061] It should be noted that the above method enables accurate determination of whether a search request includes key information.
[0062] Optionally, in the information retrieval method provided in this application embodiment, retrieving bidding information based on retrieval information and retrieval request to obtain retrieval results includes: retrieving bidding information based on retrieval information and retrieval request to obtain initial retrieval results; obtaining a preset target thesaurus, wherein the target thesaurus includes keywords for at least one supplementary retrieval dimension; and filtering the initial retrieval results based on the target thesaurus to obtain retrieval results.
[0063] The target processing system can retrieve bidding information based on user-supplemented search information and the original search information in the search request, thus obtaining initial search results. For example, during the search process, bidding information containing user-supplemented search information or the original search information in the request is identified as the initial search results.
[0064] In an optional embodiment, the target processing system may store a preset target thesaurus. The target thesaurus may include keywords for at least one supplementary search dimension. This target thesaurus may be preset by staff, and the supplementary search dimension differs from the target search dimension; the supplementary search dimension is pre-specified by the staff. The target processing system may be a system within the target financial institution, and the keywords in the target thesaurus may correspond to bidding information that the target financial institution is particularly interested in. By designing a target thesaurus, on the one hand, it can help reduce the amount of input for users; on the other hand, it can relatively focus on bidding information that is more important to the target financial institution.
[0065] For example, supplementary search dimensions could include the publishing organization, the publishing field, or business keywords.
[0066] After obtaining the target thesaurus, the initial search results are filtered based on the target thesaurus to obtain the final search results. For example, each bidding information in the initial search results is compared with the target thesaurus to check if any words from the target thesaurus exist in the bidding information. If they do, the bidding information is identified as a search result; otherwise, it is not identified as a search result.
[0067] It should be noted that the above method enables a secondary filtering of search results based on a preset target thesaurus, thereby improving the accuracy of the search results.
[0068] Optionally, in the information retrieval method provided in this application embodiment, the initial search results are filtered according to the target thesaurus to obtain the search results, including: determining the keywords of the target supplementary search dimension from the target thesaurus according to the search request, wherein the target supplementary search dimension refers to the supplementary search dimension missing in the search request; and filtering the initial search results based on the keywords of the target supplementary search dimension to obtain the search results.
[0069] Optionally, the target processing system can extract keywords from the search request and determine the search dimension to which each keyword belongs. Then, it compares the search dimensions to which the keywords belong with the target thesaurus to find the supplementary search dimensions missing in the search request. In other words, it analyzes the user's search request to determine which supplementary search dimensions (such as time, target audience, etc.) are not mentioned in the request.
[0070] After identifying the keywords for the target supplementary search dimensions, the system uses these keywords as filtering conditions to perform a secondary screening of the initial search results. For example, it uses text matching techniques, such as keyword search, regular expressions, or natural language processing, to check whether each bidding information in the initial search results contains these keywords for the target supplementary search dimensions. Optionally, bidding information containing keywords for the target supplementary search dimensions in the initial search results is selected as search results, while bidding information not containing these keywords in the initial search results is prohibited from being selected as search results.
[0071] For example, if the supplementary search dimensions in the target thesaurus include publishing unit and publishing field, and the user has already specified the publishing unit in the search request, then the publishing field is determined to be the target supplementary search dimension, while the publishing unit is not.
[0072] It should be noted that, through the above method, the user's intent is prioritized during the supplementary search process, and secondary filtering is performed only based on the supplementary search dimensions omitted by the user, thereby further improving the accuracy of the search results.
[0073] Optionally, in the information retrieval method provided in this application embodiment, retrieving bidding information based on retrieval information and retrieval request to obtain retrieval results includes: obtaining multiple preset search sources, wherein each search source includes bidding information; retrieving bidding information from the multiple search sources based on retrieval information and retrieval request to obtain retrieval results.
[0074] Optionally, the preset multiple search sources refer to a series of data sources pre-configured by the system, including but not limited to bidding websites, related publishing platforms, industry report databases, etc. These data sources are the main channels for obtaining bidding information. For example, the system maintains a list of search sources, each of which is connected to its specific interface or data crawling technology to retrieve data from these sources in real time or periodically.
[0075] Optionally, the target processing system can retrieve bidding information from multiple search sources based on the user-supplemented search information and the original search information in the search request to obtain search results. Optionally, a concurrent processing mechanism, i.e., multi-threading or distributed search technology, can be used to perform search operations on multiple data sources simultaneously to improve search speed and efficiency.
[0076] It should be noted that the above method enables accurate determination of the data source range, thereby improving retrieval efficiency and accuracy.
[0077] Optionally, in the information retrieval method provided in this application embodiment, retrieving bidding information based on the retrieval information and retrieval request to obtain retrieval results includes: retrieving bidding information based on the retrieval information and retrieval request to obtain initial retrieval results; determining the bidding termination date and bidding object of each bidding information in the initial retrieval results; and determining the bidding information in the initial retrieval results whose bidding termination date is later than the target date and whose bidding object includes the first object as the retrieval results.
[0078] Optionally, bidding information can be retrieved based on the user-supplemented search information and the original search information in the search request to obtain initial search results.
[0079] After obtaining the initial search results, for each bidding information, the bidding end date and the target bidders can be identified. For example, keyword recognition can be used, employing regular expressions to determine the bidding end date and target bidders from the bidding information. The bidding end date refers to the last date specified in the bidding announcement for companies to submit their bids, and the target bidders refer to the intended group of bidders or the type of companies targeted in the bidding announcement.
[0080] For each bidding information in the initial search results, check whether its bidding termination date is later than the preset target date, and confirm whether the bidding object includes the first object. Bidding information with a bidding termination date later than the target date and whose bidding object includes the first object will be identified as search results; otherwise, bidding information will not be identified as search results. The aforementioned target date is predetermined by staff, and the first object can be the financial institution to which the initiator of the search request belongs (e.g., the target financial institution), or other preset enterprises or institutions.
[0081] It should be noted that the above method enables a secondary screening process that combines time and bidding target factors, thereby further improving the accuracy of the search.
[0082] In an optional embodiment, the above-mentioned secondary retrieval using the target thesaurus, secondary retrieval using the tender termination date and the tendering object, and retrieval in the search source are not contradictory. That is, the target processing system can choose one or two of these methods to retrieve tender information, or it can retrieve tender information based on the aforementioned three methods.
[0083] Optionally, in the information retrieval method provided in this application embodiment, after retrieving bidding information based on the retrieval information and retrieval request and obtaining the retrieval results, the method further includes: extracting target information from the bidding information in the retrieval results, wherein the target information includes at least one of the following: bidding entity, title, introduction, bidding time information, source website; and sending the retrieval results and target information to the device terminal of a second object, wherein the second object is the initiator of the retrieval request.
[0084] Optionally, the target processing system can use keyword-based regular expressions or natural language processing techniques to extract target information from the bidding information.
[0085] After obtaining the target information, the search results and the target information are sent to the second party's device terminal. For example, the search results and target information can be sent to the second party via SMS, email, or other means.
[0086] It should be noted that the above methods can improve the user experience and information delivery quality of the bidding information retrieval service.
[0087] In an optional embodiment, the target processing system may obtain historical tender documents that match the tender information in the search results, and then generate the current tender document based on the historical tender documents.
[0088] Therefore, the method provided in this application achieves the goal of retrieving bidding information based on complete search information, realizes the technical effect of improving the accuracy of retrieving bidding information, and solves the technical problem of low accuracy in retrieving bidding information in related technologies.
[0089] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
