Specifically, the questions to be replied received in the present application refer to all questions posed by the user.
And 102, under the condition that the similarity between the problem to be replied and each preset problem is smaller than a preset similarity threshold, carrying out named entity recognition on the problem to be replied to obtain a named entity recognition result of the problem to be replied.

In this embodiment, when determining the similarity between the to-be-replied question and each preset question, it may be determined whether the similarity between the to-be-replied question and each preset question is smaller than a preset similarity threshold, and if both are smaller than the similarity threshold, at this time, the named entity recognition may be performed on the received to-be-replied question according to a preset manner, so as to obtain a named entity recognition result of the to-be-replied question.

Specifically, to take a simple example, the sentence "Xiaozhangying 8 am going to school class. "in, named entity identification should be able to extract information, name: small, time: morning 8, site: school.
Among them, Named Entity Recognition (NER) is an important basic tool in application fields such as information extraction, question-answering system, syntactic analysis, machine translation, and plays an important role in the process of putting natural language processing technology into practical use. Generally speaking, the task of named entity recognition is to identify named entities in three major categories (entity category, time category and number category), seven minor categories (person name, organization name, place name, time, date, currency and percentage) in the text to be processed.

In the information reply method in the embodiment of the application, in the process of the received reply information of the problem to be replied, the similarity between the problem to be replied and each preset problem is compared with a preset similarity threshold, and under the condition that the similarity between the problem to be replied and each preset problem is determined to be smaller than the preset similarity threshold, named entity recognition is carried out on the problem to be replied so as to obtain a named entity recognition result of the problem to be replied, and the reply information of the problem to be replied is determined and the reply information is output according to the named entity recognition result. Therefore, when the similarity between the received problem to be replied and each preset problem is smaller than a preset similarity threshold, the problem to be replied is subjected to named entity recognition, and reply information of the problem to be replied is determined according to the recognition result of the named entity of the problem to be replied. Therefore, the problem to be replied is replied by combining the named entity recognition result of the problem to be replied, and the man-machine interaction experience is improved.
Fig. 2 is a flowchart illustrating another information replying method according to an embodiment of the present disclosure.
As shown in fig. 2, the method may include:
In some embodiments of the present application, in order to accurately determine the named entity recognition result of the to-be-replied question through the named recognition model, the named recognition model in this embodiment may include a semantic representation layer, a conditional random field layer, and a full connection layer, which are sequentially connected, and the to-be-replied question is input to the pre-trained named entity recognition model, so as to obtain the named entity recognition result of the to-be-replied question in a possible implementation manner that: inputting the question to be replied into a semantic representation layer to obtain semantic representation characteristics of the question to be replied; inputting the semantic representation characteristics into a conditional random field layer to obtain the probability of each participle in the problem to be replied corresponding to the named entity category; and inputting the probability of the named entity category corresponding to each participle into the full connection layer to obtain the named entity recognition result corresponding to the problem to be replied.
In this embodiment, in order to accurately determine the recognition result of the named entity of the to-be-replied question through the named entity recognition model, the named entity recognition model may be trained in combination with training data. The exemplary embodiment of training the named recognition model is as follows: the method comprises the steps of obtaining training data, wherein the training data comprise sample problems and named entity identification marking data of the sample problems, inputting the sample problems into a semantic representation model to obtain semantic representation characteristics of the sample problems, inputting the semantic representation characteristics into a conditional random field layer to obtain the probability of each participle in a problem to be replied corresponding to a named entity category, inputting the probability of each participle corresponding to the named entity category into a full connection layer to obtain a named entity identification result corresponding to the problem to be replied, and adjusting parameters of the conditional random field layer and the full connection layer in the named entity identification model according to the named entity identification result and the named entity identification marking data until the named entity model meets preset conditions to obtain the trained named entity identification model. In some embodiments, the semantic representation layer may be a pre-trained language model in order to accurately represent semantic features of the questions to be replied. As an exemplary embodiment, the pre-training Language model may be a bert (bidirectional Encoder retrieval from transforms) model, or an enhanced semantic Representation model ernie (enhanced Language retrieval with information entities).
The BERT model is a pre-training language model which is learned by performing unsupervised learning pre-training on large-scale unmarked corpus by using a transformer architecture; the goal of the BERT model is to obtain the rich semantic information-containing Representation of the text using large-scale markerless corpus training [ i.e.: semantic representation of text ]. The semantic representation of the text is then fine-tuned in a specific Natural Language Processing (NLP) task, and ultimately applied to the NLP task. BERT training procedure brief introduction: BERT is also pre-trained. Its weight is learned beforehand by two unsupervised tasks. These two tasks are: a Masked Language Model (MLM) and a next sentence prediction (next sense prediction). BERT applies mode profile-BERT does not need to be trained from scratch for every new task. Instead, fine-tuning (fine-tuning) is performed on the pre-trained weights.
In some embodiments, the conditional random field layer may be a conditional random field model. Conditional random fields CRF (conditional random fields) are a kind of discriminative probability model, which is a kind of random field commonly used for labeling or analyzing sequence data, and is a conditional probability distribution model P (Y | X) representing a markov random field of another set of output random variables Y given a set of input random variables X, that is, CRF is characterized by assuming that the output random variables constitute a markov random field. Conditional random fields can be viewed as a generalization of the maximum entropy markov model over the labeling problem.
Among them, the fully connected layers (FC) play a role of "classifier" in the whole convolutional neural network. If we say that operations such as convolutional layers, pooling layers, and activation function layers map raw data to hidden layer feature space, the fully-connected layer serves to map the learned "distributed feature representation" to the sample label space. In practical use, the fully-connected layer may be implemented by a convolution operation: a fully-connected layer that is fully-connected to the previous layer may be converted to a convolution with a convolution kernel of 1x 1; while the fully-connected layer whose preceding layer is a convolutional layer can be converted to a global convolution with a convolution kernel of hxw, h and w being the height and width of the preceding layer convolution result, respectively.
In an embodiment of the present application, in order to accurately determine the reply information of the to-be-replied question, one possible implementation manner of determining the reply information of the to-be-replied question according to the named entity identification result is as follows: determining the category number of the named entity categories according to the named entity identification result; and under the condition that the number of the categories is one, generating corresponding question-answering sentence information according to the text information corresponding to the named entity categories, and taking the question-answering sentence information as reply information of the question to be replied.
In some embodiments, under the condition that the number of the categories is multiple, the problem to be replied is disassembled to disassemble the problem to be replied into multiple sentences; determining a named entity type of each statement, and generating question-back statement information corresponding to the statement according to text information corresponding to the named entity type; and generating reply information of the question to be replied according to the question return information corresponding to each statement.
In some embodiments of the present application, in a case where the name recognition category is an entity word type, corresponding question-back sentence information may be generated according to text information corresponding to the entity word.
For example, in a case where it is determined that the named entity category of the question to be answered is the entity word category, and the entity word type corresponds to a "white bar", the generated question-back sentence information may be "ask, what question you want to consult the white bar? ".
For another example, the question to be replied is "what is the white bar of i today, what is the gold bar? "the password entity category in the question to be replied may be determined as an entity word category through named entity recognition, and the text information corresponding to the entity word category is" white bar "and" gold bar ", and the generated question-answering information may be" according to the text information corresponding to the entity word type: ask, which question you want to ask for the white bar, gold bar? ".
In other embodiments, when the named entity type is an attribute word type, corresponding question-back statement information may be generated according to text information corresponding to the attribute word type.
For example, in the case that the named entity category of the question to be answered is determined as the attribute word category, and the attribute word corresponds to the "quota", the generated question-asking sentence information may be "ask, what service is you want to know about the quota question? ".
For another example, the question to be answered is "amount and balance, the named entity identification is performed on the question to be answered, the type of the named entity of the question to be answered is determined to be an attribute word type, two attribute words are" amount "and" balance ", at this time, according to the text information corresponding to the attribute word type, the generated question-answering sentence information is" ask, and you want to know which question in the amount and balance.
In other embodiments, when the named entity category is an operation word, determining whether the number of the operation words is multiple; and if the number of the operation words is multiple, generating corresponding question-back sentence information according to the text information corresponding to each operation word.
For example, when the named entity category of the question to be answered is determined as the operation word, and the "how to open, how to activate, and how to query" corresponding to the operation word, the generated question-answering sentence information may be "ask, who wants to know how to open, how to activate, and which question to query? ".
In other embodiments, if the number of the operation words is one, the text information corresponding to the operation words is obtained, the entity word information corresponding to the text information is obtained, and the corresponding question-back sentence information is generated according to the entity word information.
For example, when the named entity category of the question to be answered is determined as the operation word, and if the operation word corresponds to "how to open", the generated question-back sentence information may be "ask, which one of the open questions in the common white bar, the gold bar, and the small vault wants to know? ".
It can be understood that, in different application scenarios, the above manner of obtaining the entity word information corresponding to the text information is different, and is illustrated as follows:
as an exemplary implementation manner, the entity word information corresponding to the text information may be obtained according to a correspondence relationship between the text information corresponding to the operation word and the entity word information that is stored in advance.
It should be noted that the text information and the entity word information corresponding to the operation word in the corresponding relationship are identified by a named entity identification model. Specifically, a plurality of entity words corresponding to each operation word may be counted, and a corresponding relationship between the operation word and the entity word may be established.
As another exemplary embodiment, in order to quickly and accurately determine the entity word information corresponding to the corresponding text information, one possible implementation manner of acquiring the entity word information corresponding to the text information is as follows: and acquiring corresponding service information, acquiring an entity word information set corresponding to the service information, and acquiring entity word information corresponding to the text information from the entity word information set.
The service information may include service name information and/or service identification information, and the embodiment is not limited in this respect.
And step 204, outputting the reply message.
In the information reply method in the embodiment of the application, in the process of the received reply information of the problem to be replied, the similarity between the problem to be replied and each preset problem is compared with a preset similarity threshold, and under the condition that the similarity between the problem to be replied and each preset problem is determined to be smaller than the preset similarity threshold, named entity recognition is carried out on the problem to be replied so as to obtain a named entity recognition result of the problem to be replied, and the reply information of the problem to be replied is determined and the reply information is output according to the named entity recognition result. Therefore, when the similarity between the received problem to be replied and each preset problem is smaller than a preset similarity threshold, the problem to be replied is subjected to named entity recognition, and reply information of the problem to be replied is determined according to the recognition result of the named entity of the problem to be replied. Therefore, the problem to be replied is replied by combining the named entity recognition result of the problem to be replied, and the man-machine interaction experience is improved.
In order to make the technical solutions of the present application clearly understood by those skilled in the art, the technical solutions of this embodiment are further described below with reference to fig. 3, it should be noted that subj in fig. 3 represents an entity word, pred represents an operation word, and prop represents an attribute word.
Specifically, in step 301, after the user inputs a query term (query), the query term may be used as a question to be replied. Correspondingly, the named entity recognition model can be carried out on the query word through the named entity recognition model so as to obtain the named entity recognition result of the question to be replied.
Correspondingly, step 302, several categories in the named entity recognition result are determined. In this embodiment, three categories are taken as an example, and are an entity word category, an operation word category and an attribute word category. That is, several categories in the named entity recognition result are judged.
Step 304 may perform a single element range based on one of three categories in the case where one category is included in the named entity recognition result:
in step 305, if the category number identified by the named entity only contains one sub j, ask "ask, what question you want to ask sub j? "; if > 2 or more subj are included, ask "ask a question, which question of subj1, subj2, subj3.. will you consult? "
In some embodiments, where multiple types are included in the named entity recognition result, multiple element processing logic may be employed, with punctuation and single element processing logic processing per sentence.
An exemplary procedure for asking back the post-logic process is as follows: three slots are opened in redis before the question-back logic is performed: subj, pred, prop, are initially empty, and if there is only one subj, ask "ask, what question you want to ask subj? ". After a user inputs a query, a model identifies a subj, the subj is filled into a subj slot position, after the user answers a question, element NER identification is carried out according to the question answered by the user, pred or prop is identified, the corresponding slot position is filled, question splicing is carried out, response logic is triggered again, and all the slot positions are cleared until field words are switched. If > 2 or more subj are included, ask "ask a question, which question of subj1, subj2, subj3.. will you consult? ". The user answers subj, fills the slot corresponding to subj, goes through the order element question-back logic, and queries to continue filling the slot until finding faq answer.
Among them, redis called: remote Dictionary Server (Remote data service), is a memory-based high-performance key-value database. faq is an abbreviation for freqently assigned Questions, the "Frequently Asked question".
