As shown in fig. 7A, fig. 7A is a schematic flowchart of an interaction method provided by the embodiment of the present disclosure, where the interaction method specifically includes the following steps:

and S710, responding to the preset updating rule, and acquiring target access data within the preset time length of the user.

The preset update rule may be an access time for performing the update prompt, and if the preset update rule is time period information corresponding to one hour, it is determined that the preset update rule is reached when it is determined that the current time reaches one hour after the last update.

The preset time length may be a preset time period that is determined based on the current access time and is earlier than the current access time, for example, the preset time length may be within a previous hour corresponding to the current access time.

For example, if the current access time of the user is 2022.6.6,10, the corresponding preset time duration may be 2022.6.6,9, where the preset time duration may be adaptively set based on the update rule, such as within the first half hour, or within the first office hour, which is not specifically limited by the present disclosure.

The target access data may be access data for which the display device has not determined response information, that is, after receiving the target access data sent by the user, the display device does not search for response information corresponding to the target access data, or searches that the degree of matching between the response information corresponding to the target access data and the target access data is low, and does not feed back to the user.

It should be noted that, the user may input the target access data through a search box in the display interface of the display device, or the user may input the search target access data through voice, so that the display device receives the target access data sent by the user.

As exemplarily shown in fig. 7B, the user may input characters in the search box of the display device via a remote controller or other control device to obtain the target access data, and then trigger the "search" button to transmit the target access data to the display device.

And the area corresponding to the search box of the display equipment can also be used for setting and displaying the habitual terms of the user, so that the quick input of the user is facilitated.

As exemplarily shown in fig. 7C, one or more display areas for displaying the habitual terms of the user may be provided at positions around the search box of the display apparatus, such as a display area 1 for displaying a first habitual term of the user, a display area 2 for displaying a second habitual term of the user, and a display area 3 for displaying a third habitual term of the user.

The display positions corresponding to the

display areas

1, 2, and 3 may be determined correspondingly based on the display position of the search frame, for example, the display positions may be set at the display position below the display position of the search frame, or the display positions corresponding to the

display areas

1, 2, and 3 may be hidden and displayed on the search interface of the display device, and after the user triggers the display identifier, the display contents corresponding to the

display areas

1, 2, and 3 may be displayed.

The habitual terms of the user displayed in the search interface of the display device can be set and modified by the user, and can also be set by the display device based on the historical access condition of the user. The present disclosure is not particularly limited thereto.

Specifically, the habitual terms of the user may be some access data that is accessed by the user more frequently, for example, the first habitual term may be "popular movie", the second habitual term may be "popular comprehension", the third habitual term may be "tv drama with the highest popularity", and the like.

As exemplarily shown in fig. 7D, the user may trigger to start the voice interaction function of the display device through a preset voice instruction, and speak out specific characters corresponding to the target access data after the voice interaction function of the display device is started, so that the display device can obtain the target access data according to the voice data input by the user.

In addition, after the target access data within the preset time length of the user is obtained, data cleaning can be performed on the target access data to obtain effective data of the target access data.

Wherein the data cleansing may include: the washing of punctuation marks, the washing of partial intention words, etc.

The washing of the punctuation marks can be a washing operation performed on all punctuation marks included in the target access data, wherein when the sentence of the target access data is long and has a plurality of periods in the middle, the target access data can be firstly subjected to sentence breaking based on the periods to obtain a plurality of segmented sentences, and then each segmented sentence is subjected to washing of the punctuation marks.

When punctuation marks are cleaned on each segmented sentence, corresponding operations can be simultaneously carried out, and therefore symbol cleaning can be effectively and quickly achieved.

The partial intention words can be 'I want', 'help me', 'voice assistant image words', 'play', etc., the cleaning of the partial intention words can be to remove the set partial intention words, if the target access data is 'play song 1', then the partial intention words can be removed to obtain 'song 1'.

With reference to the foregoing example, assuming that the target access data received by the display device is "voice assistant, i want to listen to song 2", the target access data is cleaned by punctuation marks to obtain "voice assistant i want to listen to song 2", then partial intention words are cleaned, and "voice assistant" and "i want" are removed, so that "listen to song 2" is finally obtained.

The index related to the target access data can be newly added for the target access data, and specifically, the index can include: text content (after data cleaning), access times, positioning service, positioning mode, time and the like.

See table 1 below for details.

Table 1 data presentation table 1

Wherein "123" represents a correct song title, and "423" and "523" represent words that are homophonic but different from the correct song title.

The positioning service is a scene service corresponding to text content, such as music, chat and the like, the return reply is a reply returned to the user by the display device based on the search of the target access data, the time is displayed in a timestamp mode, the positioning mode corresponds to different search engines, such as R corresponds to a first search engine, and S corresponds to a second search engine.

In addition, when data analysis is performed on the target access data, a positioning service set for analysis can be screened based on service types, some preset services (such as own services and services in specific applications) are not analyzed, and the linguistic data with a strong operation mode as a positioning mode is not analyzed.

And S720, updating the dynamic dictionary base based on the target access data.

The dynamic dictionary base can be a dictionary base constructed in advance based on historical access data of the user, can be used for carrying out semantic understanding on the access data, and is convenient for timely and effectively analyzing the intention of the user.

The dynamic dictionary base may store the entity words and the domain information corresponding to the entity words, the entity words may be the text content exemplified as above, and the domain information may be the location service exemplified as above, which specifically includes: music (music), movies (movie), televises (teleplay), chats (chat), and the like.

And S730, responding to the current access data of the user, and determining response information corresponding to the current access data based on the dynamic dictionary library.

The current access data of the user is access data, which is received by the display device and sent by the user to the display device at the current time, of "play song 2", "i want to listen to song 2", "search song 2", "play movie 3", "i want to watch movie 3", "search movie 3", "play drama 4", "i want to watch drama 4", "search drama 4", "i want to chat in idle, voice assistant", "open voice assistant", and the like.

After receiving the current access data of the user, the display device can match the entity words in the dynamic dictionary library with the current access data (text content) to obtain the matched entity words matched with the current access data, so that the display device can quickly find out the response information associated with the matched entity words based on the matched entity words to feed back the matched entity words to the user in time.

For example, if the current access data of the user is "play song 2", the matching entity word obtained by matching the current access data is "song 2", and the domain information corresponding to "song 2" is "music", the response information corresponding to the current access data is "music song 2".

The current access data of the user is "play movie 3", the matching entity word obtained by matching the current access data is "movie 3", and the field information corresponding to the movie 3 "is" movie ", so that the response information corresponding to the current access data is" movie 3".

The current access data of the user is 'play 4', the matching entity word obtained by matching the current access data is 'play 4', the field information corresponding to the 'play 4' is 'teleplay', and then the response information corresponding to the current access data is 'teleplay 4'.

The current access data of the user is ' i want to chat ', ' matching entity words obtained by matching the current access data are ' chat ', ' chat ' and ' chat ', the corresponding domain information of the ' chat ' is ' chat ', and then the corresponding response information of the current access data can be obtained as ' chat '.

And S740, displaying the response information corresponding to the current access data.

And the display equipment can display the response information corresponding to the current access data to the user on the display interface based on the obtained response information.

The display device may display the response information corresponding to the current access data in a preset region, where the preset region may be one sub-region in a display interface of the display device, or the preset region may be all display regions in the display interface of the display device.

As exemplarily shown in fig. 7E, when the response information corresponding to the currently accessed data is "music song 2", the response information "music song 2" corresponding to the currently accessed data may be displayed in the display area 4, so that the user can effectively know the search result.

As exemplarily shown in fig. 7F, when the response information corresponding to the current access data is "movie 3", the response information "movie 3" corresponding to the current access data may be displayed in the display area 5.

It should be noted that, in the present disclosure, data analysis on target access data and data response on current access data may be implemented in different service resources, for example, a data analysis process may perform word segmentation extraction and data analysis under a test environment service, and does not occupy on-line voice understanding server resources, and thus does not affect semantic response speed of formal environment service.

Based on the description of the above embodiments, the target access data may include: and each group of access data can comprise a plurality of pieces of access data, and the matching degree between the entity words in the plurality of pieces of access data is greater than the threshold value of the matching degree.

The target access data can be clustered to obtain multiple groups of clustering data (multiple groups of access data), each group of clustering data comprises multiple pieces of access data, each piece of access data comprises entity words, and the matching degree of the entity words in the multiple pieces of access data in each group of clustering data is greater than the threshold value of the matching degree.

It should be noted that, during clustering, similarity clustering may be performed based on a Term Frequency-Inverse text Frequency index (TF-IDF) method in combination with an edit distance method and a pinyin similarity calculation method, and during clustering, correct data of the same time period of the previous hour and the previous day of the same day are added to perform cluster classification on user original data.

When the dynamic dictionary base is updated, each group of access data in the multiple groups of access data can be independently processed, similarity matching is carried out on each group of access data to determine a first similarity value corresponding to each group of access data, when the first similarity value of the first access data is detected to be larger than a preset first threshold value, similarity comparison is continuously carried out on the first access data and the preset word base to obtain a second similarity value, and when the second similarity value of the second access data is detected to be larger than a preset second threshold value, comparison words corresponding to entity words in the second access data and entity words in the preset word base are added to the dynamic dictionary base, so that the entity words with high accuracy in user access data can be effectively determined according to the preset word base.

The first access data is one or more groups of access data with similarity values larger than a preset first threshold, and the second access data is one or more access data in the one or more groups of access data.

The preset lexicon can be a pre-constructed hot lexicon, and can store entity names (comparison words) in the user utterance with correct response in a certain period of time, such as video names, music names, news entries and other entity names in the user utterance with correct response in the last month, and can be obtained mainly through ranking list and user data statistics.

Specifically, the hot thesaurus may be ordered according to a time dimension, with a time priority: one hour before the same day > the same time period before the same day > other time periods on the same day (other priorities decrease with decreasing time), and then the request amount ordering of the users is accumulated according to the ordering of the request times.

And when the second similarity value of the third access data is detected to be smaller than or equal to a preset second threshold value, the field information of the credible entity words and the credible entity words in the third access data is obtained, the field information of the credible entity words and the credible entity words is added to the cache library, and the dynamic dictionary library is updated based on the cache library.

And the credible entity words are entity words with the highest confidence in the third access data.

The first access data is one or more groups of access data with similarity values larger than a preset first threshold value, and the third access data is one or more access data in the one or more groups of access data.

Therefore, the entity words with the highest confidence coefficient can be selected to be added into the cache library, so that the entity words can be conveniently expanded, and the word quantity of the dynamic dictionary library is increased.

In addition, when the target access data is a group of data or a piece of data, the calculation of the second similarity can be directly carried out.

When the first similarity value of the fourth access data is detected to be smaller than or equal to a preset first threshold value, adding the fourth access data to the cache library; and updating the dynamic dictionary base based on the cache base.

The fourth access data is one or more groups of access data with the similarity value smaller than or equal to a preset first threshold, and the fourth access data is added into the cache library to expand the entity words, so that the word quantity of the dynamic dictionary library is further expanded.

As exemplarily shown in fig. 8A, the cache library (extensible library) is constructed in the following manner.

And S810, acquiring original data.

The original data is user access data acquired within a preset time length.

S820, similarity calculation is carried out on the original data, and a first similarity value is determined.

Wherein, the similarity calculation may include: the TF-IDF method combines an editing distance mode and a pinyin similarity calculation method.

S830, judging whether the first similarity value is larger than T1, if so, executing S840, and if not, executing S880.

Wherein, T1 is a preset first threshold.

And S840, generating a unified statement cluster to obtain multiple groups of access data.

Wherein, by generating the uniform speaking distance, the plurality of pieces of access data can be clustered.

And S850, judging whether the second similarity value is larger than T2, if so, executing S860, and if not, executing S870.

And T1 is a preset second threshold, and the second similarity value is obtained by comparing the similarity of the multiple groups of access data with the hot word library.

And S860, outputting a mapping pair of the error-correcting word and the original word.

And S870, selecting the most credible corpus, searching by combining the keywords, and adding the most credible corpus into the library to be expanded.

The keywords (key words, service positioning words, such as movies, music, news, and the like) are predetermined in the early stage, and can be determined by reference word matching and knowledge graph calculation, the reference words can be mapped differently according to different services, and the initial mapping is exemplarily shown in table 2 below.

Table 2 mapping table

FIELD	Key word	Generalization to
			Film and television	Film	Film, movie, video app
Film and television	TV play	Drama and TV drama
			Film and television	Video	Watch with
Music	Song (music)	Songs, heaps, musicApp

For the calculation of the instruction map, a triple () determination field can be established through semantic tags, which mainly covers the statement that there is no intention word but there is a related tag, and a connection diagram can be exemplarily shown in fig. 8B.

And S880, outputting the single text and adding the single text into the library to be expanded.

Wherein, the cache library can include: when the candidate words or the candidate words and the domain information corresponding to the candidate words are updated based on the cache library, determining that the first words have corresponding domain information from the cache library, and determining the first entity words corresponding to the first words based on the domain information corresponding to the first words, wherein the first words are at least one of the candidate words; and adding the first entity word and the domain information corresponding to the first word to a dynamic dictionary library.

Wherein, the first word is one or more words with domain information in the cache library.

In addition, the dynamic dictionary base can be expanded based on some words without domain information in the cache base, and the word quantity of the dynamic dictionary base is further improved.

Specifically, it may be determined from the buffer library that the second word does not have corresponding domain information, and the second word is segmented to obtain at least one segmented word, where the second word is at least one word in the candidate words; determining that at least one segmentation word has a corresponding second entity word, and adding the second entity word and the domain information corresponding to the second word to the dynamic dictionary database

Wherein the second word is one or more words without domain information in the cache library.

The second words without the domain information can be labeled, the words to be labeled can adopt a sequence labeling algorithm, the intention words are removed, a Chinese syntax segmentation algorithm can be adopted in other mining modes to adopt a maximum matching algorithm, and if the words are hit, the entry analysis is finished, so that word segmentation which causes other irrelevant intention expressions to be added to a knowledge base and influences other conditions due to too fine granularity of mining data can be eliminated.

The dynamic dictionary database is stored in a preset cache region, and when the dynamic dictionary database is updated, the dynamic dictionary database in the preset cache region can be updated based on the cache region.

Specifically, the dynamic dictionary base can be used as a secondary word segmentation dictionary through the storage function of a Search server (Elastic Search, es), only the cache related to the dynamic dictionary base is refreshed, the wireless pressure is applied, the label and the error-correcting word requested by the user at high frequency can be automatically added in a delayed mode for 1 hour, and the accuracy of user experience and semantic understanding is guaranteed.

When the current access data of the user is semantically understood, the semantic understanding can be realized by a main dictionary and a dynamic dictionary, the main dictionary can be firstly used for word segmentation, if only one word segmentation is carried out, the semantic understanding can be directly executed, and for other conditions, the secondary word segmentation dictionary (dynamic dictionary) can be executed based on the word segmentation of the main dictionary.
