Step 103: Determine at least one target question-answer pair that meets the matching requirement according to the target entity attribute and the pre-built knowledge base.

In this embodiment, the pre-built knowledge base may include a large number of question-and-answer pairs, and each question-and-answer pair includes not only questions and answers, but also retrospective data of the answers. The retrospective data are references, that is, the The answers are obtained from references to ensure the accuracy and traceability of the answers.

Specifically, in this embodiment, as an optional implementation manner, semantic analysis is performed on the questions in each question-answer pair to obtain the entity attributes of each question. The target entity attribute is then matched with the entity attribute of each question to obtain the matching degree of the target entity attribute with the entity attribute of each question. It is judged whether the matching degree meets the matching requirement, and if the matching requirement is met, the question-and-answer pair corresponding to at least one question and answer that meets the matching requirement is used as the target question-answer pair.

After the target question-and-answer pair is determined, if there are multiple target question-answer pairs, they can be arranged in sequence on the search result display interface according to the matching degree for simple display.

Step 104: In response to the user's triggering operation on the target question and answer pair, the target question and answer pair is displayed, and the target question and answer pair includes: the target question, the target answer and the retrospective data, and the retrospective data is a reference document.

In the pre-built knowledge base, each question-and-answer pair has traceability data corresponding to the answer, and the traceback data is in the form of references, which can ensure the accuracy and traceability of the answers to each question, so users After the answer is searched, the accuracy of the answer can be determined based on the retrospective data, which can be applied to the search in the medical field, and improves the experience of searching for an answer in the medical field.

Embodiment 2

Fig. 4 is a flowchart of the medical question and answer method provided in the second embodiment of the present invention. As shown in Fig. 4 , the medical question and answer method provided by the present embodiment is based on the medical question and answer method provided by the first embodiment of the present invention. 103 is further refined, and also includes the step of building a knowledge base, where the knowledge base is a knowledge graph, and the medical question answering method provided by this embodiment includes the following steps.

Step 201: Obtain document type and format information in the medical field configured by medical professionals through a configuration interface that meets accurate requirements.

Optionally, in this embodiment, a client for building a knowledge graph is set on the user terminal of a medical professional, and after the medical professional logs in to the client, the relevant certification of whether it is a medical professional is performed. After passing, the configuration interface can be opened to configure the document types and format information that meet the exact requirements in the medical field. For example, the configured document types that meet the exact requirements can be clinical guidelines, excellent medical journals, excellent medical papers, etc. The configured document format that meets the exact requirements can be image format, PDF format, etc.

Step 202: Acquire the construction corpus of the knowledge graph according to the document type and format information that meet the exact requirements.

Specifically, in this embodiment, documents in the medical field can be obtained by accessing a third-party platform, and then each document can be parsed to extract documents that meet the exact requirements of the configuration in terms of document type and format, so as to obtain the construction The corpus of the knowledge graph, which can be represented as a construction corpus.

Among them, the medical field can be the field of geriatric care, the field of infectious diseases, the field of hematology, or the field of other departments.

Step 203: Receive a schema set in the medical field input by a medical professional through a configuration interface.

In this embodiment, in addition to the configuration controls for document types and formats, the configuration interface also includes configuration controls for schema collections in the medical field.

When constructing the knowledge graph, the SPO triplet data should be extracted from the construction corpus. The SPO triplet data refers to the three elements consisting of entity S, relation P (or attribute P), and entity O (or attribute value O). A tuple, where S is the subject of P and O is the object of P. When extracting the SPO triplet data, it is necessary to determine the relationship/attribute P, the subject (S) type and the object (O) type of the SPO triplet data to be extracted from the construction corpus. The relationship/attribute P, as well as the subject (S) type and object (O) type of the P constitute the schema set.

Since medical professionals have a very professional understanding of the medical field, the schema collection in the medical field is configured by the medical professional through the configuration interface, and the schema collection can be configured accurately.

It can be understood that each medical professional specializes in different medical fields, so the medical field that the medical professional is good at can be determined according to the certification information of the medical professional, and the medical field is displayed in the configuration interface, so that each medical professional can Each medical professional configures the corresponding schema set according to the medical field they are good at.

Step 204, extracting the construction triplet data within the scope of the schema set from the construction corpus.

In this embodiment, an extraction algorithm can be used to extract the triplet data in the construction corpus, and when extracting the triplet data, the schema set is used as a constraint, so that the extracted triplet data is in the schema set Within the scope, the extracted triplet data is determined as the triplet data for constructing the knowledge graph, which can be expressed as constructing triplet data.

Step 205: Acquire the constructed question and answer pair corresponding to the constructed triple data.

In this embodiment, after the construction triplet data is extracted from the corpus, the corresponding questions, answers and retrospective data can also be extracted from the corresponding corpus, and the corresponding questions, answers and retrospective data can be expressed as constructing a question-and-answer pair .

Step 206 , constructing a knowledge graph according to the constructing triplet data and the corresponding constructing question-answer pairs.

Specifically, in this embodiment, all construction triplet data can be obtained, the association relationship between each construction triplet data can be extracted, and a graph structure can be constructed according to each association relationship, so as to construct a knowledge graph. And the mapping relationship between each constructed triple data and the corresponding question-answer pair is stored in the knowledge graph.

In the medical question answering method provided by this embodiment, in the process of constructing the knowledge graph, before acquiring the construction corpus of the knowledge graph, the document types and formats that meet the exact requirements in the preset medical field are configured by medical professionals through the configuration interface. information, so the accuracy and authority of the constructed corpus are guaranteed. In addition, when the construction triple data is extracted from the construction corpus, the schema set in the medical field is also configured by medical professionals, so the accuracy of the extracted construction triple data is ensured. Furthermore, the constructed knowledge graph can accurately reflect the objective relationship between objects in the medical field and the accuracy of question-and-answer pairs.

Optionally, in this embodiment, before step 206, the following steps are further included:

Step 2051: Send the construction triplet data and the corresponding construction question and answer pair to the user terminal corresponding to the medical professional, so that the user terminal displays the construction triplet data and the corresponding construction question and answer pair for review by the medical professional.

Step 2052: Receive the audit result sent by the user terminal.

Step 2053: If it is determined that the audit result is not passed, the revised construction triplet data and the corresponding construction question-and-answer pair are acquired.

In this embodiment, the construction triplet data and the corresponding construction question and answer pairs are sent to the user terminal corresponding to the medical professional, and after the construction triplet data and the corresponding construction question and answer pair are displayed on the user terminal, the medical professional The triplet data and the corresponding construction question-and-answer pair are reviewed. If the construction triplet data and the corresponding construction question-and-answer pair meet the accurate requirements, the review is passed. If the construction triplet data and the corresponding construction question-and-answer pair do not meet the exact requirements, the audit will fail. After the review fails, the construction triplet data and/or the corresponding construction question-and-answer pair are corrected.

It is understandable that if the audit is passed, the audit result that has passed the audit will be sent to the medical question-and-answer device. If the audit is not passed, the result of the audit that has not passed the audit will be combined with the revised construction triplet data and the corresponding construction question-and-answer pair. Send it to the medical question answering device, so that the medical question answering device can obtain the revised construction triplet data and the corresponding construction question answering pair.

Correspondingly, step 206 is specifically: constructing a knowledge graph according to the revised construction triplet data and the corresponding construction question and answer pairs.

In the medical question answering method provided in this embodiment, in the process of constructing the knowledge graph, after acquiring the constructing triplet data and the corresponding constructing question and answer pair, it is sent to the user terminal of the medical professional, and the medical professional will review it, so that the The accuracy of constructing triplet data for constructing knowledge graph and corresponding constructing question-answer pairs further improves the accuracy of knowledge graph.

Step 207: Receive the target key field input by the user through the search input box in the homepage operation interface.

Step 208: Perform semantic analysis on the target key field to obtain the target entity attribute corresponding to the target key field.

In this embodiment, the implementation manners of steps 207 to 208 are the same as the implementation manners of steps 101 to 102 in Embodiment 1 of the present invention, and details are not repeated here.

Step 209: Determine at least one target question-answer pair that meets the matching requirement according to the target entity attribute and the pre-built knowledge base.

Optionally, in this embodiment, step 209 includes the following steps:

Step 2091: Obtain a candidate triplet set from a pre-built knowledge graph according to the attribute of the target entity, where the candidate triplet set includes at least one candidate triplet.

Specifically, in this embodiment, the attribute of the target entity is parsed, and triplet data whose correlation degree with the attribute of the target entity meets the preset degree of correlation is obtained from a pre-built knowledge graph as candidate triplet data, and the candidate triplet The tuple data constitutes a set of candidate triples.

The correlation between the attribute of the target entity and each triplet data can be represented by the number of associated nodes. If the number of associated nodes between the attribute of the target entity and a certain triplet data is less than the preset number of nodes, it is determined that the triplet data satisfies the preset degree of relevancy, if the number of associated nodes between the attribute of the target entity and a certain triplet data is greater than or equal to If the number of nodes is preset, it is determined that the triplet data does not meet the preset correlation degree.

Alternatively, other data may be used to represent the correlation between the attribute of the target entity and the data of each triple, which is not limited in this embodiment.

Step 2092 , perform matching calculation between the target entity attribute and the candidate triplet using a matching model, so as to obtain a candidate triplet that meets the matching requirements as the target triplet.

Specifically, the target entity attribute and each candidate triplet are input into the matching model, and the matching model performs matching calculation on the target entity attribute and each candidate triplet, and calculates the matching degree between the target entity attribute and each candidate triplet, The candidate triplet data with the matching degree greater than the preset matching degree is determined as the candidate triplet that meets the matching requirement, and the candidate triplet that meets the matching requirement is determined as the target triplet.

The matching model may be a deep learning model, such as a convolutional neural network model, a recurrent neural network model, or the like.

Step 2093: Obtain the target question-answer pair corresponding to the target triplet from the pre-built knowledge graph.

In this embodiment, since each construction triplet and the corresponding construction question-and-answer pair are stored in the knowledge graph, the target question-answer pair corresponding to the target triplet is obtained from the knowledge graph, and the target question-answer pair includes the target question , target answers and retrospective data.

It should be noted that, before step 2091, the attribute of the target entity can also be verified through the knowledge graph. If the attribute of the target entity is not the entity attribute of the medical field corresponding to the knowledge graph, the user searched for the attribute corresponding to the attribute of the target entity is determined. The question is an invalid question, and a quick response to the invalid question is possible.

Step 210: In response to the user's click operation on the target question and answer pair, the target question and answer pair is displayed, and the target question and answer pair includes: the target question, the target answer and the retrospective data, and the retrospective data is a reference.

In this embodiment, the implementation manner of step 210 is similar to the implementation manner of step 104 in Embodiment 1 of the present invention, and details are not repeated here.

In the medical question answering method provided in this embodiment, when at least one target question answering pair that meets the matching requirements is determined according to the attributes of the target entity and the pre-built knowledge base, the candidate triplet set is obtained from the pre-built knowledge graph according to the attributes of the target entity, The candidate triplet set includes at least one candidate triplet; the target entity attribute and the candidate triplet are matched and calculated by using a matching model, so as to obtain the candidate triplet that meets the matching requirements as the target triplet; The target question-answer pair corresponding to the target triplet is obtained from the knowledge graph. First, the set of candidate triples matching the attributes of the target entity is obtained from the knowledge graph, and then the attribute of the target entity is matched with the candidate triples in the set of candidate triples, which can guarantee the obtained target triples. While it is an accurate triple, it effectively reduces the calculation amount of the matching algorithm for the matching calculation, and improves the efficiency of determining the target question-answer pair that meets the matching requirements.
