With continued reference to fig. 2, a flow 200 of one embodiment of a digest generation method according to the present disclosure is shown. The abstract generation method of the embodiment comprises the following steps:
step 201, a target document is obtained.
In this embodiment, the execution subject of the digest generation method may acquire the target document in various ways. For example, the executive agent may crawl financial reports, or event statistics documents, published by various companies from the network. Here, the target document may be a document containing a plurality of parameters and parameter values.
Step 202, according to the type of the target document and the parameter set matched with the type, determining a plurality of parameters and values of the parameters included in the target document.
The execution subject may determine the type of the target document after obtaining the target document. The types of target documents may include financial reports, event statistics, and the like. The execution subject can analyze the words at the specific position of the target document to determine the type of the target document. For example, the performing agent may analyze the preamble portion of the financial report to determine the type of target document as a financial report. The executing agent may obtain a set of parameters that match the types described above. For example, the set of parameters that match the financial report may include: revenue, total profit, etc. The set of parameters that match the event statistics may include: a three point hit rate, a number of shots taken, etc. The execution subject may find each parameter in the parameter set in the target document, and determine the parameter included in the target document. The executing agent may then also determine values for the parameters from the target document using a deep-learning model, KV (key-value) algorithm.
Step 203, determining a target template matched with the target document according to the plurality of parameters.
The execution body may also determine a target template matching the target document according to a plurality of parameters in the target document. Here, the target template may be a template including the plurality of parameters described above. The target template may include a plurality of sentences, each sentence including a plurality of word slots, and the execution subject may fill the plurality of word slots with a plurality of parameters and values of the plurality of parameters.
Step 204, determining the abstract of the target document according to the values of the parameters and the target template.
The execution subject may populate the target template with values for the plurality of parameters to obtain a summary of the target document. Or the execution subject may generate a sentence including values of the plurality of parameters from the sentence included in the target template, resulting in the digest.
With continued reference to fig. 3, a schematic diagram of one application scenario of the summary generation method according to the present disclosure is shown. In the application scenario of fig. 3, the server 301 receives a financial report of a company, and the server 301 first extracts core elements therein and determines values of the respective core elements. And then filling the values of the core elements into a target template to obtain the summary of the financial report.
The abstract generation method provided by the embodiment of the disclosure can automatically extract parameters from the target document, match a proper template, and automatically generate the abstract, thereby improving the generation efficiency of the abstract.
With continued reference to fig. 4, a flow 400 of another embodiment of a digest generation method according to the present disclosure is shown. As shown in fig. 4, the method of the present embodiment may include the following steps:
step 401, obtain the target document.
Step 402, extracting a plurality of candidate parameters included in a target document by using at least one parameter extraction algorithm; and determining parameters and values of a plurality of parameters included in the target document according to the type of the target document, the parameter set matched with the type and the candidate parameters.
In this embodiment, the executing agent may extract a plurality of candidate parameters included in the target document using a plurality of parameter extraction algorithms. This is because different parameter extraction algorithms extract different types of parameters with different accuracies. Specifically, the parameter extraction algorithm may include a depth language model, a KV algorithm, a table extraction, and the like. The deep language model is used for extracting fields such as operating profit, net profit, operating income and the like by using a deep learning named entity recognition technology for parameters appearing in paragraphs. For the parameters with relatively fixed and regular format, such as company name, company stock number and financial newspaper release date, KV extraction algorithm is used for extracting corresponding industry parameters. Part of the financial elements appear in the table. For the part of elements, whether the table is extracted or not is judged according to the matching degree of the table header and the element schema, and then the corresponding cell content is extracted.
Step 403, normalizing the plurality of parameters.
In this embodiment, in order to unify parameters with the same meaning expressed differently, the above parameters may be normalized, so that the subsequent abstract generation is more accurate.
Step 404, determining a target sentence matched with each parameter from a preset sentence set; and combining the target sentences to obtain a target template.
In this embodiment, the execution subject may obtain the statement set in advance. Each statement in the statement set comprises at least one parameter. The execution body may set a sentence including each of the plurality of parameters as a target sentence. And then combining the target sentences to obtain a target template.
In this embodiment, the execution subject may further determine the target template through step 405:
step 405, determining a template containing a plurality of parameters as a target template from a preset template set.
In this embodiment, the execution subject may obtain the template set in advance. Each template in the set of templates may include a plurality of parameters therein. The execution subject may take a template including the plurality of parameters described above in the template set as a target template.
Step 406, in response to determining that the target template includes an additional parameter other than the plurality of parameters, calculating values of the additional parameter according to the values of the plurality of parameters; and filling the values of the parameters and the values of the additional parameters into the target template to obtain the abstract of the target document.
In this embodiment, if additional parameters are included in the target template in addition to the above parameters, for example, the parameter A, B is included in the target document, and the parameter A, B, C is included in the target template, then the parameter C is an additional parameter. The execution subject may calculate the value of the additional parameter using the values of the plurality of parameters according to the association relationship between the plurality of parameters and the additional parameter. The executing agent may then populate the target template with values for the plurality of parameters and values for the additional parameters, resulting in a summary of the target document.
The abstract generation method provided by the embodiment of the disclosure can determine a proper target template for different target documents, so that the obtained abstract is more accurate.
