The method for identifying the intention based on the artificial intelligence is applied to a user terminal, and is executed through application software installed in the user terminal, namely, the user terminal is a terminal device, such as a desktop computer, a notebook computer, a tablet computer or a mobile phone, for executing the method for identifying the intention based on the artificial intelligence so as to identify the intention of information input by a user.

As shown in fig. 1, the method includes steps S110 to S160.

And S110, acquiring input information of a user.

Input information of a user is acquired. Specifically, the user terminal may obtain the input information of the user through text information input by the user at the user terminal, or may obtain the input information of the user through voice information input by the user at the user terminal. That is, the user terminal may be a terminal device having a voice collecting function and/or a text information collecting function, such as a mobile phone, a tablet computer, a car phone, and the like.

And S120, processing the input information to obtain words in the input information.

The input information is processed to obtain words in the input information. Specifically, after the input information of the user is obtained, the user terminal processes the input information to obtain the words in the input information. For example, the user terminal obtains the input information of the user as "i want to inquire the balance of the bank card", and the user terminal processes the input information, so that the obtained terms are "i", "want", "inquire", "bank card", "balance", respectively, which are the terms in the input information.

In an embodiment, as shown in fig. 2, step S120 includes sub-steps S121, S122 and S123.

And S121, judging the type of the input information.

And judging the type of the input information. Specifically, the input information of the user acquired by the terminal may be text information or voice information, and the voice information is a word that needs to be converted into text information and then processed to obtain the input information in the subsequent steps, so that the terminal needs to judge the input information of the user after acquiring the input information of the user to obtain the type of the input information.

And S122, if the type of the input information is voice input information, converting the voice input information into text information.

And if the type of the input information is voice input information, converting the voice input information into text information. Specifically, when a user inputs information from a voice information collecting function at a user terminal, the terminal may determine that the input information is voice input information, and may convert the voice input information to obtain text information corresponding to the voice information.

And S123, processing the text information to obtain words in the input information.

The text information is processed to obtain words in the input information. For example, when the text information is "i want to query the balance of the bank card", the user terminal processes the text information to obtain the words in the input information, where the words are "i", "want", "query", "bank card", "balance", respectively.

In one embodiment, as shown in fig. 3, step S123 includes sub-steps S1231, S1232, and S1233.

And S1231, performing word segmentation processing on the text information according to a preset word segmentation processing model to obtain a text vocabulary.

And performing word segmentation processing on the text information according to a preset word segmentation processing model to obtain a text vocabulary. Specifically, the word segmentation processing model is preset in the terminal, and the word segmentation processing model is used for performing word segmentation processing on the text information, so as to obtain a vocabulary of the text information. For example, when the text information is "i want to inquire the balance of the bank card", the word segmentation processing model performs word segmentation processing on the text information to obtain the text vocabulary, and the text vocabulary is X ═ i, i want, i ask, silver, line, card, remainder, and amount }.

And S1232, marking the vocabulary in the text vocabulary to obtain the marked vocabulary.

And labeling the vocabulary in the text vocabulary to obtain the labeled vocabulary. Specifically, after the text vocabulary is labeled, the attribute of the vocabulary in the text vocabulary and the context connection relationship of the vocabulary in the text vocabulary can be obtained. For example, when the text vocabulary is X ═ i, i.

And S1233, analyzing the marked words to obtain words in the input information.

For example, after the attributes and connection relations of "i", "want", "search", "query", "bank", "line", "card", "remaining", "amount" in the text vocabulary are determined, the words in the input information are obtained by combining and splitting according to the attributes and connection relations, and the words are "i", "want", "query", "bank card", "remaining" and "remaining amount", respectively.

S130, acquiring a knowledge graph matched with the input information according to the words in the input information and a preset domain knowledge graph, wherein the domain knowledge graph comprises at least one knowledge graph.

And acquiring a knowledge graph matched with the input information according to the words in the input information and a preset domain knowledge graph, wherein the domain knowledge graph comprises at least one knowledge graph. Specifically, the domain knowledge graph is a knowledge graph established in a specified domain, wherein the domain knowledge graph may have a plurality of knowledge graphs of different types in the same domain, for example, a knowledge graph in a bank domain may be established, a knowledge graph in the bank domain may have a knowledge graph of an inquiry intention, or a knowledge graph of an elevated amount, and words in the input information are matched with knowledge factors in the knowledge graph of the inquiry intention in the bank domain and knowledge factors in the knowledge graph of the elevated amount to obtain a knowledge graph matched with the input information.

In one embodiment, as shown in fig. 4, step S130 includes sub-steps S131 and S132.

S131, judging whether the words are matched with preset knowledge factors in the knowledge graph or not.

And judging whether the words are matched with preset knowledge factors in the knowledge graph. The term is obtained by screening the input information, and the knowledge factor refers to information used for representing a knowledge graph in the established knowledge graph. And matching the words with all knowledge factors in the knowledge graph to obtain a result of whether the knowledge graph is matched with the input information. Specifically, the word is matched with all knowledge factors in the knowledge graph, and if the word senses of the word are similar to the word senses of the knowledge factors, the word can be judged to be matched with the knowledge factors, so that a result of whether the knowledge graph is matched with the input information is obtained. For example, when the input information is "i want to inquire the balance of the bank card", the modifying terms "want" and "in the input information are removed, and the terms are obtained as i, inquiry, the bank card and the balance respectively; as shown in fig. 14, fig. 14 is a knowledge graph of credit card query intentions in the banking field, which is established in an embodiment of the present invention, wherein knowledge factors in the knowledge graph of fig. 14 are money, consumption, customers, queries, credit cards, attributes, amounts, and quantities, respectively, and according to me, query, bank card, and balance in the terms, for example, whether the knowledge graph of fig. 14 contains knowledge factors identical or similar to the terms is found, so as to obtain a result of whether the knowledge graph of fig. 14 matches the input information. Where the word senses of the bank card in the words are similar to the word senses of the credit card in fig. 14, it may be determined that the knowledge factor "credit card" in the knowledge graph of fig. 14 matches the "bank card" in the words.

And S132, if the words are matched with the knowledge factors, acquiring a matched knowledge graph according to the knowledge factors.

And if the words are matched with the knowledge factors, acquiring a matched knowledge graph according to the knowledge factors. Specifically, after the words are matched with the knowledge factors, all knowledge maps containing the knowledge factors in the field are obtained. For example, when the input information is "improve money that can be used by me", the modifying terms "can" and "in the input information are removed, and the terms are respectively improved, me, use and money, and whether the knowledge graph in fig. 14 and 15 contains the same or similar knowledge factors as the terms or not is searched according to the improved, me, use and money in the terms, wherein fig. 14 is the established knowledge graph of the credit card query intention in the bank field in the embodiment of the present invention; FIG. 15 is a diagram illustrating an established knowledge graph of credit card credit line increases in the banking domain in accordance with an embodiment of the present invention; thereby obtaining the knowledge-graph of fig. 14 and 15 to match the input information and obtaining the knowledge-graph of fig. 14 and 15.

And S140, judging the number of the knowledge graphs matched with the input information.

And judging the number of the knowledge maps matched with the input information. Specifically, the domain knowledge graph includes at least one knowledge graph, the number of words in the input information filled into a preset domain knowledge graph to obtain a knowledge graph matched with the input information is at least one, and the intentions represented by each knowledge graph in the domain knowledge graph are different, so that the number of knowledge graphs obtained from the domain knowledge graph needs to be judged to screen out the knowledge graph which best meets the intentions of the user. For example, when the words in the input information include "bank card", the knowledge graph of the credit card query intention and the knowledge graph of the promotion amount in the bank field established as shown in fig. 14 and fig. 15 are obtained; when the words in the input information include "bank card" and "inquiry", a knowledge map of the credit card inquiry intention in the banking field is obtained as established in fig. 14.

S150, if the number of the knowledge graphs matched with the input information is 1, determining the knowledge graph matched with the input information as a target knowledge graph, and obtaining the intention of the user according to the target knowledge graph.

And if the number of the knowledge graphs matched with the input information is 1, determining the knowledge graph matched with the input information as a target knowledge graph and obtaining the intention of the user according to the target knowledge graph. Specifically, when the number of the knowledge graph matched with the input information is 1, the knowledge graph can be determined to be a target knowledge graph of the input information, and the intention of the user who inputs the information can be obtained through the target knowledge graph. For example, when the words in the input information include "bank card" and "inquiry", a knowledge graph of the credit card inquiry intention in the bank domain is obtained as set up in fig. 14, and a target knowledge graph of the input information can be determined, and the intention of the user who inputs the information can be obtained through the target knowledge graph.

And S160, if the knowledge graph matched with the input information is a plurality of knowledge graphs, screening the knowledge graphs according to a preset screening rule to obtain a target knowledge graph and obtain the intention of the user.

And if the knowledge graph matched with the input information is a plurality of knowledge graphs, screening the knowledge graphs according to a preset screening rule to obtain a target knowledge graph and obtain the intention of the user. Specifically, the screening rule is rule information for screening the knowledge graphs to obtain the knowledge graph which best meets the user intention. Because the intention represented by each knowledge graph in the domain knowledge graph is different, and the knowledge graph matched with the input information obtained through the input information can be a plurality of knowledge graphs representing different intentions, when the knowledge graphs are screened, the knowledge graphs can be screened through the analysis result after being analyzed according to the middle overall semantics of the input information, so that the target knowledge graph conforming to the input information can be obtained, and the intention of the user can be obtained.

In addition, the number of knowledge factors matching the words in each of the plurality of knowledge maps may be calculated, and the knowledge map with the largest number of knowledge factors may be used as the target knowledge map of the input information to obtain the intention of the user.

In one embodiment, as shown in fig. 5, step S160 includes sub-steps S161 and S162.

S161, calculating the number of target knowledge factors in each knowledge graph of the knowledge graphs, wherein the target knowledge factors are knowledge factors matched with the words in the knowledge graphs.

And calculating the number of target knowledge factors in each knowledge graph of the plurality of knowledge graphs, wherein the target knowledge factors are knowledge factors matched with the words in the knowledge graphs. Specifically, the target knowledge factor is a knowledge factor matched with the words in each knowledge graph. For example, when the input information is 'improve money that can be used by me', and the acquired knowledge graphs are the knowledge graph of the query intention and the knowledge graph of the promotion amount, the number of the knowledge factors matched with the words in the input information in the knowledge graph of the query intention and the knowledge graph of the promotion amount is calculated respectively, so that 3 knowledge factors in the knowledge graph of the query intention are calculated to be matched with the words in the input information, and 4 knowledge factors in the knowledge graph of the promotion amount are matched with the words in the input information.

And S162, taking the knowledge graph with the most target knowledge factors as a target knowledge graph to obtain the intention of the user.

And taking the knowledge graph with the most target knowledge factors as a target knowledge graph to obtain the intention of the user. Specifically, the input information is "increase money that i can use", the number of the target factors contained in the knowledge graph of fig. 14 is 3, and the number of the target factors contained in the knowledge graph of fig. 15 is 4, so that the knowledge graph of fig. 15 can be used as a target knowledge graph to obtain the intention of the user.

In one embodiment, as shown in fig. 6, step S162 includes sub-steps S1621 and S1622.

S1621, judging whether the number of the knowledge graphs with the most target knowledge factors is larger than 1.

And judging whether the number of the knowledge-graphs with the most target knowledge factors is more than 1. Specifically, the knowledge graph with the most target knowledge factors may have two or more different types of knowledge graphs, and when the number of the target knowledge factors in the knowledge graph is the same as the number of words in the input information, the knowledge graph of the user cannot be obtained. For example, if the input information is "i inquire whether money available in the credit card is increased", the number of the target knowledge factors in the knowledge graph inquiring the intention and the knowledge graph promoting the amount is the same as the matching number of the terms in the input information, that is, the knowledge graph with the most target knowledge factors is two knowledge graphs.

S1622, if the number of the knowledge graphs with the most target knowledge factors is larger than 1, acquiring a target knowledge graph from the knowledge graphs with the most target knowledge factors according to the dependency syntax relationship of the words, and obtaining the intention of the user.

And if the number of the knowledge graphs with the most target knowledge factors is more than 1, acquiring a target knowledge graph from a plurality of knowledge graphs with the most target knowledge factors according to the dependency syntax relation of the words, and acquiring the intention of the user according to the target knowledge graph. Specifically, the syntactic analysis is to analyze the dependency relationship between words labeled in the text vocabulary. For example, when the terms in the input information are "i", "come", "query", "down", "credit card", "middle", "usable", "money", "whether", "raise", "changed", respectively, it can be determined that the user's intention of the input information is a knowledge graph conforming to the query intention by the dependency syntax relationship between the terms in the input information, thereby determining that the user's intention is the query intention. The dependency relationship of the input information "i inquire whether money available in the credit card is increased" is as shown in fig. 16, and the structural relationship between terms in the input information can be obtained through fig. 16, so that the deep semantics of the input information is obtained, and the real intention of the user is obtained.
