Please refer to FIG. 2, which illustrates a flow 200 of one embodiment of an artificial intelligence based human-computer interaction method in accordance with the present application. It should be noted that the method for human-computer interaction based on artificial intelligence provided by the embodiments of the present application may be performed by the

terminal devices

101, 102, and 103 in FIG. 1, for example, artificial intelligence configured by the

terminal devices

101, 102, and 103. The human-computer interaction application is executed, and accordingly, the artificial intelligence-based human-computer interaction device may be disposed in the

terminal devices

101, 102, and 103. The method includes the following steps:

Step 201: Receive an interactive statement input by a user.

In this embodiment, when the human-computer interaction application based on the artificial intelligence on the terminal device receives the human-computer interaction, the user inputs the interactive statement by using a keyboard, a voice, or the like. For example, when a user wants to know what a good movie to watch, he can input "What good movie have you recently?" by voice. After receiving the interactive statement for input, the voice may be first recognized to obtain a statement corresponding to the voice.

Step 202: Extract a type keyword from a preset type of search result in a search result corresponding to the interaction statement in the search engine.

In this embodiment, the type keyword includes: a subject name of a preset type of search result. After the interaction statement input by the user is received through step 201, in order to identify whether the interaction statement has an acquisition requirement for the preset type of information, the search result corresponding to the interaction statement input by the user in the search engine may be first acquired. For example, the interaction statement input by the user may be sent to the server, and the search engine of the server may use the interactive statement as a search type, ie, query, and use the inverted index to find the search result corresponding to the interactive statement. Then, the type keyword can be extracted from the search result of the preset type of the search result corresponding to the interactive sentence in the search engine.

In some optional implementation manners of the embodiment, the preset type includes: a movie type, a music type.

Taking the preset type as the movie type as an example, the user input is received in step 201. After the inter-statement, in order to identify whether the interactive statement has a need for the information of the movie type, the search result corresponding to the interactive sentence input by the user in the search engine may be first obtained. For example, the interaction statement input by the user may be sent to the server, and the search engine of the server may use the interactive statement as a search type, ie, query, and use the inverted index to find the search result corresponding to the interactive statement. Then, the type keyword may be extracted from the search result belonging to the movie type of the search result corresponding to the interactive sentence in the search engine, and the type keyword includes the topic name of the search result. The subject name of the movie type search result can be the movie name. For example, when the search result is presented in the html page, the information is defined in the html tag. When the content in the tag of the html page is detected as a link, and the link contains a keyword of the type of the video, the search result may be determined as movie types. The title of the search result can be defined in the title tag, and the content in the title tag can be extracted.

In some optional implementation manners of the embodiment, extracting the type keyword from the preset type of search results in the search result includes: performing a preset type search in a preset number of search results corresponding to the interaction statement a position of the result, a score of a preset type of search result is calculated, the score indicates a popularity level of the preset type of search result; a judgment score is greater than a score threshold; and when the score is greater than the score threshold, from a preset type of search result Extract the type keywords.

Please refer to FIG. 3, which shows an exemplary flowchart of a score extraction type keyword according to a preset type of search result.

Taking the preset type keyword as the movie name example, firstly obtain the first 10 search results in the search engine when the query is searched on the pc end and the mobile terminal, and the first 10 search results and the movie "Forrest Gump" The name of the movie in the relevant search results. The position of the movie result in the first 10 search results on the PC side and the position of the movie result in the first 10 search results on the mobile terminal are respectively taken as input parameters of the nonlinear function, and the score on the PC end and the score of the mobile terminal are obtained. Then, with different weights, the PC-side score and the mobile terminal's score are fitted to a final score final_score. A threshold threshold can be divided according to the scores of the search results corresponding to the queries of the plurality of strong demands. Taking the recognition of the movie type requirement as an example, a score threshold threshold can be divided according to the scores of the search results corresponding to the query of the plurality of pre-identified strong movie requirements. When final_score is greater than the fractional threshold threshold, the power parsed from the search results can be adopted. Film name.

In some optional implementation manners of the embodiment, calculating a score of the preset type of search result includes: calculating a score of the preset type of search result by using the following formula: pc_score=f(pc_index); wise_score=f(wise_index) ;final_score=g(w_pc*pc_score+w_wise*wise_score); where f is a nonlinear function and g is a linear function; pc_index is a preset number of searches corresponding to the interactive statement in the search engine when searching on the pc side The position of the first preset type of search result in the result; wise_index is the position of the first preset type of search result among the preset number of search results corresponding to the interactive sentence in the search engine when searching on the mobile terminal ;w_pc and w_wise are the weights corresponding to the pc end and the mobile terminal.

Taking the interaction statement input by the user, including "Forrest Gump" as an example, the first 10 search results in the search engine when searching for the "Gump" and the search engine in the mobile terminal are searched separately. Top 10 search results. The positions of the top 10 search results in the search engine and the search results of the movie type in the top 10 search results in the search engine when the mobile terminal performs the search may be separately determined. Then, the "A-Gump" can be searched on the pc side, and the position of the first search result belonging to the movie type in the first 10 search results in the search engine is used as the input parameter of the preset nonlinear function, and the PC end is obtained. Score. The position of the first one of the first 10 search results in the search engine belonging to the movie type may be used as the input parameter of the preset nonlinear function when the "Forrest Gump" searches in the mobile terminal, and the mobile terminal score is obtained. The sum of the product of the pc end score and the preset pc end weight value and the product of the mobile terminal score and the preset mobile terminal weight value is used as an input parameter of the preset linear function, thereby obtaining a score of the movie type search result.

Please refer to FIG. 4A, which shows an exemplary effect diagram of extracting type keywords from search results in a search engine corresponding to the PC side.

When you enter the query "Forrest Gump" in the search box on the pc side, you can get the search results associated with "Forrest Gump". The default type of search results are movie type search results, such as the website of the movie "Forrest Gump" and the "Gump of Forrest Gump". The type keyword can be extracted from the search result of the movie type, for example, the movie name "A" is extracted from the theme name of the search result corresponding to the website of the movie playing "Forrest Gump". Gan Zhengchuan."

Referring to FIG. 4B, an exemplary effect diagram of extracting a type keyword from search results in a search engine corresponding to a mobile terminal is shown.

When the query "Agan Zhengchuan" is input in the search box of the mobile terminal, since the search engine has the error correction function, the search result associated with the correct movie name "Forrest Gump" can be obtained. For example, the website of the movie "Forrest Gump" and the film review of "Forrest Gump". The type keyword can be extracted from the search result of the movie type as the movie name "Forrest Gump".

In this embodiment, the search engine is used to update the search result corresponding to the query and the error correction and optimization of the query are performed, and a type keyword such as a movie name is extracted from the search result. Thus, in the case where the question input by the user includes a type keyword such as the movie name of the latest release movie, or a colloquial expression in the interactive sentence, such as a movie name or a movie name, a typo can be searched for from the search engine. The correct movie name is extracted from the result, which provides guarantee for the subsequent identification of the requirement of the interactive statement, such as the requirement of the movie type.

For example, when the movie "will be indefinitely" is about to be released, if only the rule is matched, since "after the indefinite period" does not belong to the idiom, the word does not exist in the rule matching template, resulting in the interaction statement. The word is not recognized in the requirement identification, and the requirement cannot be identified. For another example, when the user enters the name of the movie "Forrest Gump" and enters the wrong name "Agan Zhengchuan" to perform rule matching only, the rule matching template only contains the correct word "Forrest Gump" As a result, the word cannot be recognized in the requirement identification of the interactive statement, and the requirement cannot be identified.

In this embodiment, when the interactive statement input by the user in the human-computer interaction includes "there is no future", since the search engine has a fast update function, the search result corresponding to the obtained interactive statement includes the upcoming release. The movie's movie name "will be indefinite", so that the movie name of the upcoming movie can be extracted from the search result corresponding to the interactive sentence. When the interactive statement input by the user in the human-computer interaction includes "A Gan Zheng Chuan", since the search engine has the error correction function, the search result corresponding to the obtained interactive sentence is the correct word corrected by the search engine. Gan Zhengchuan" search results obtained by searching, so that the correct movie name "Forrest Gump" can be extracted from the search results.

Step 203: Determine whether the type keyword is associated with the acquisition requirement of the preset type information, and obtain the judgment result.

In this embodiment, after the search result corresponding to the interactive sentence in the search engine is acquired through step 202, and the type keyword is extracted from the search result of the preset type in the search result, it may be determined whether the extracted type keyword is It is associated with the acquisition requirement of the preset type of information, and the judgment result is obtained. For example, when the type keyword is a movie name, it can be judged whether the movie name is associated with the acquisition request of the movie type information.

Step 204: Generate an answer corresponding to the interaction statement in a manner corresponding to the determination result.

In this embodiment, after determining whether the type keyword is associated with the acquisition requirement of the preset type of information by step 203, and obtaining the determination result, the answer corresponding to the interaction statement may be generated in a manner corresponding to the determination result.

Taking the type keyword as the movie name as an example, when it is recognized in step 203 that the movie name is not associated with the acquisition requirement of the movie type information, the artificial intelligence based human-computer interaction application can generate the movie name as a common word. answer. When the acquisition requirement of the movie name and the movie type information is recognized by step 203, the artificial intelligence based human-computer interaction application can generate an answer based on the acquisition requirement of the movie type information. For example, to get a link to the movie coupon for the movie, then generate the answer "I recommend you a few cinemas + links that are close to you and have discounts."

Please refer to FIG. 5, which illustrates a flow 500 of another embodiment of an artificial intelligence based human-computer interaction method in accordance with the present application. It should be noted that the method for human-computer interaction based on artificial intelligence provided by the embodiments of the present application may be performed by the

terminal devices

101, 102, and 103. Human-computer interaction application execution. The method includes the following steps:

Step 501: Receive an interactive statement input by a user.

In this embodiment, the human-computer interaction application based on the artificial intelligence on the terminal device can be used to receive an interactive statement input by the user through a keyboard, a voice, or the like when the human-computer interaction is received. For example, when a user wants to know what a good movie to watch, he can input "What good movie have you recently?" by voice. After receiving the interactive statement for input, the voice may be first recognized to obtain a statement corresponding to the voice.

Step 502, a preset type in the search result corresponding to the interaction statement in the search engine Type keywords are extracted from the search results.

In this embodiment, after receiving the interaction statement input by the user through step 501, the search result corresponding to the interaction statement input by the user in the search engine may be first acquired. Then, the score of the preset type of search result may be calculated based on the preset type of search result at the position of the search result corresponding to the interactive sentence. The score of the preset type of search result indicates the popularity of the preset type of search result. When the score is greater than the score threshold, the type keyword can be extracted from the preset type of search result.

Taking the interaction statement input by the user, including "Forrest Gump" as an example, the first 10 search results in the search engine when searching for the "Gump" and the search engine in the mobile terminal are searched separately. Top 10 search results. The positions of the top 10 search results in the search engine and the top 10 search results in the search engine when searching on the mobile terminal can be separately determined by "Forrest Gump". Then, the "A-Gump" can be searched on the pc side, and the position of the first search result belonging to the movie type in the first 10 search results in the search engine is used as the input parameter of the preset nonlinear function, and the PC end is obtained. Score. The position of the first one of the first 10 search results in the search engine belonging to the movie type may be used as the input parameter of the preset nonlinear function when the "Forrest Gump" searches in the mobile terminal, and the mobile terminal score is obtained. The sum of the product of the pc end score and the preset pc end weight value and the product of the mobile terminal score and the preset mobile terminal weight value is used as an input parameter of the preset linear function, thereby obtaining a score of the movie type search result.

Step 503: Determine, according to the probability of the common word, whether the type keyword is associated with the acquisition requirement of the preset type of information, and obtain the judgment result.

In this embodiment, before the interaction statement input by the user is received through step 501, the web crawler type keyword may be pre-selected, and the common word probability of the captured type keyword being a common word may be calculated. Taking the type keyword as the movie name, you can use the web crawler to capture a large number of movie names from the website in advance. Then, the ordinary word probability of the movie named ordinary word is calculated separately.

In this embodiment, the common word probability of the type keyword extracted by step 502 can be compared with the determined probability threshold strong probability threshold or standard probability threshold according to the common word probability of the pre-calculated massive type keyword. , the type keyword is Whether it is associated with the acquisition requirement of the preset type of information, the judgment result is obtained.

Taking the type keyword as a movie name example, the common word probability of the movie name extracted by step 502 and the determined probability threshold value may be based on the common word probability of the pre-calculated movie name. Compare. When the common word probability corresponding to the movie name is greater than the determined probability threshold, it may be determined that the movie name is not associated with the acquisition requirement of the movie type information. When the common word probability corresponding to the movie name is less than the determined probability threshold, it may be determined that the movie name is associated with the acquisition requirement of the information of the movie type. Thereby, it is finally determined whether or not the movie name extracted by step 502 has a request for acquisition of information of a movie type.

In this embodiment, whether the strong threshold or the standard threshold is adopted is determined by the rule matching whether the interaction statement input by the user received in step 501 has a preset type of information. For example, the rule matching template containing the preset requirement keyword matches the interactive sentence input by the user, and determines whether the interactive keyword input by the user includes the demand keyword.

Taking the information of the preset type of movie as an example, the preset demand keywords are “have a sequel?” and “when a release”. When the rule matching template matches the interaction statement input by the user, and it is determined that the interaction statement input by the user includes the requirement keyword, it may be determined that the interaction statement input by the user is associated with the acquisition requirement of the information of the movie type. When the rule matching template matches the interactive sentence input by the user, and it is determined that the interactive keyword input by the user does not include the demand keyword, it may be determined that the interactive sentence input by the user is not associated with the acquisition requirement of the movie type information.

When it is recognized by rule matching that the interaction statement is associated with the acquisition requirement of the preset type of information, the strong probability threshold may be determined as a probability threshold for comparison with the common word probability corresponding to the type keyword. When it is recognized by the rule matching that the interactive sentence is not associated with the acquisition requirement of the preset type of information, the standard probability threshold may be determined as a probability threshold for comparison with the common word probability corresponding to the type keyword.

Please refer to FIG. 6, which illustrates an exemplary flowchart for identifying whether an interaction statement is associated with an acquisition requirement of a preset type of information by rule matching.

First, receive the query that needs to be processed, that is, the interactive statement input by the user. Then, the intent of the query and the contents of the slot under the intent of the parsing can be identified by rule matching. Demand for film For example, when the query has a movie intent, that is, the query is associated with the acquisition requirement of the information of the movie type, the slot content of each dimension obtained by the parsing, such as a movie name, an actor, and a type, may be recorded. When the query does not have a movie intent, that is, the query is not associated with the acquisition requirement of the movie type information, the slot content can be emptied.

Please refer to FIG. 7, which shows an exemplary flowchart for determining whether to filter a movie name.

Firstly, the common word probability is calculated by the massive movie name obtained by the web crawler, and a common word probability dictionary is obtained. The higher the probability of the common word, the more likely the movie is called the ordinary word.

According to the common word probability dictionary, the training is divided according to the probability value, and a strong common word set, a general common word set, and a movie demand word set are obtained. Strong probability threshold, standard probability threshold.

According to the rule matching and the analysis result of the search engine, the current movie name is subjected to different degrees of probability threshold detection, that is, a strong probability threshold corresponding to the result obtained by matching the movie name and the rule matched in the search result corresponding to the interactive sentence input by the user or Standard probability thresholds are compared. Only when the common word probability of the current movie name is lower than the threshold, the movie name is finally retained, that is, the answer is generated based on the movie name, otherwise the movie name is filtered, that is, the movie name is generated as an ordinary word.

In this embodiment, when the problem that the user input has a preset type of information acquisition requirement by the rule matching, the strong probability threshold is compared with the common word probability of the current movie name. It is judged whether the type keyword is associated with the acquisition requirement of the preset type of information. Thus, the movie name is more carefully filtered to improve the accuracy of the demand identification.

Step 504: Determine, according to the determination result, a manner of generating an answer corresponding to the question.

In this embodiment, after the step 503 is based on the probability that the type keyword is a common word, it is determined whether the type keyword is associated with the acquisition requirement of the preset type information, and after the judgment result is obtained, the generation problem may be determined according to the judgment result. The way the answer is.

When the type keyword is not associated with the acquisition requirement of the preset type of information, the answer is generated based on the type keyword as a common word; when the type keyword is associated with the acquisition requirement of the preset type of information, based on the preset type The information is obtained by the need to generate an answer.

Taking the type keyword as the movie name example, when it is recognized in step 503 that the movie name is not associated with the acquisition requirement of the movie type information, the artificial intelligence based human-computer interaction should be Use the movie name as a common word to generate an answer. When the acquisition requirement of the movie name and the movie type information is recognized by step 503, the artificial intelligence based human-computer interaction application can generate an answer based on the acquisition requirement of the movie type information. For example, to get a link to the movie coupon for the movie, then generate the answer "I recommend you a few cinemas + links that are close to you and have discounts."

Please refer to FIG. 8 , which illustrates an exemplary flowchart of an artificial intelligence based human-computer interaction method according to the present application.

First receive the content entered by the user. Taking the preset type as the movie type as an example, the user can input the interactive statement through the keyboard, voice, etc. when the human-computer interaction application based on the artificial intelligence on the terminal device receives the human-computer interaction. For example, when a user wants to know what a good movie to watch, he can input "What good movie have you recently?" by voice. After receiving the interactive statement for input, the voice may be first recognized to obtain a statement corresponding to the voice.

The search engine-based parsing system can obtain the search result of the query, that is, the content input by the user in the search engine, and extract the movie related content. The score of the search result of the movie type may be calculated based on the search result belonging to the movie type at the position of the preset number of search results corresponding to the interactive sentence, and whether the score is greater than the score threshold. When the score is greater than the score threshold, a type keyword such as a movie name is extracted from the search result of the movie type.

The rule matching based parsing system can perform rule matching on the query, that is, the content input by the user, and extract the movie related content. Then, the rule matching method can be used to identify whether the interactive sentence input by the user is associated with the acquisition request of the movie type information. When it is recognized by the rule matching that the interactive sentence is associated with the acquisition requirement of the information of the movie type, the strong probability threshold may be used as a probability threshold for comparison with the common word probability corresponding to the type keyword such as the movie name. When it is recognized by rule matching that the interactive sentence is not associated with the acquisition requirement of the preset type of information, the standard probability threshold may be used as a probability threshold for comparison with a common word probability corresponding to a type keyword such as a movie name.

The filtering system based on the common word probability can adopt the web crawler crawling type keyword in advance, and calculate the common word probability that the captured type keyword is a common word. Then, it can be judged whether the type of the keyword, for example, the common word probability corresponding to the movie name is greater than the comparison probability threshold for the comparison. When the movie name corresponds to the common word probability is less than the sum used to compare it When the threshold is used, it can be determined that the movie name is not associated with the acquisition requirement of the movie type information, that is, the current demand of the user is non-movie, then the current movie name is filtered, and the human-computer interaction application based on artificial intelligence can use the movie name as a common word. To generate an answer. When the probability of the common word corresponding to the movie name is greater than the probability threshold for comparison with the movie name, it may be determined that the movie name is associated with the acquisition requirement of the information of the movie type, that is, the current demand of the user is a movie, and the current movie name is retained, which may be based on artificial intelligence. The human-computer interaction application can generate an answer based on the acquisition requirements of the information of the movie type. For example, to get a link to the movie coupon for the movie, then generate the answer "I recommend you a few cinemas + links that are close to you and have discounts."
