Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 shows an exemplary system architecture 100 to which embodiments of the method for generating information or the apparatus for generating information of the present application may be applied.
As shown in fig. 1, a database 101, a network 102, and a server 103 may be included in the system architecture 100. Network 102 is the medium used to provide communication links between database 101 and server 103. Network 102 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
The database 101 may store a large number of sample intents and corresponding sample slot annotation text sets.
The server 103 may provide various services. For example, the server 103 may analyze and process data such as a sample slot annotation text set corresponding to a sample intention acquired from the database 101, and generate a processing result (for example, a triple).
The server 103 may be hardware or software. When the server 103 is hardware, it may be implemented as a distributed server cluster composed of a plurality of servers, or may be implemented as a single server. When the server 103 is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the method for generating information provided in the embodiment of the present application is generally performed by the server 103, and accordingly, the apparatus for generating information is generally disposed in the server 103.
It should be understood that the number of databases, networks, and servers in fig. 1 are merely illustrative. There may be any number of databases, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for generating information in accordance with the present application is shown. The method for generating information comprises the following steps:
In this embodiment, an execution subject (e.g., the server 103 shown in fig. 1) of the method for generating information may obtain a large number of sample intents and a sample slot annotation text set corresponding to each sample intention. The sample slot annotation text set corresponding to each sample intention may include a plurality of sample slot annotation texts. The sample intention may be an intention of the sample text, and the corresponding sample slot labeling text may be a slot-labeled text obtained by performing slot labeling on the sample text.
Taking the sample intention of the playing MUSIC (MUSIC _ pal) as an example, the corresponding sample slot position marking text set may include the following 3 sample slot position marking texts:
1. i listen to the third generation of [ music _ name ] of [ want _ key ] song [ music _ term ] tensor [ music _ size ].
2. Play [ wait _ key ] music [ music _ term ].
3. Come [ wait _ key ] jazz [ music _ tag ] music [ music _ term ].
Wherein, the content in the [ ] "is the marked slot position.
In this embodiment, for each sample slot, the execution subject may count occurrence of each sample slot in the sample slot annotation text set corresponding to the execution subject to determine a core sample slot and a non-core sample slot corresponding to a sample intention.
Generally, based on the sample slot annotation text set, the execution subject may generate a sample slot set corresponding to the sample intention. Specifically, the sample slot position in the sample slot position labeling text set is subjected to duplication elimination processing, and a sample slot position set can be obtained. For example, the set of sample slots to which the sample intent of playing MUSIC (MUSIC _ pay) corresponds may include five sample slots, wan _ key, MUSIC _ term, MUSIC _ singer, MUSIC _ name, and MUSIC _ tag. The core sample slot may be a sample slot in which a sample slot corresponding to one sample intention has a high probability of labeling a text, or a sample slot in which the core sample slot has a high probability of labeling a text may correspond to the sample intention. The non-core sample slot may be a sample slot of the set of sample slots other than the core sample slot. For example, since the sample slots wan _ key and MUSIC _ term appear in all sample slot annotation text corresponding to the sample intention of playing MUSIC (MUSIC _ pay), wan _ key and MUSIC _ term are core sample slots, and MUSIC _ singer, MUSIC _ name, and MUSIC _ tag are non-core sample slots.
In some optional implementations of this embodiment, the core sample slot corresponding to the sample intent may be determined by:
firstly, a sample slot position set corresponding to a sample intention is generated based on a sample slot position labeling text set.
For example, the set of sample slots to which the sample intent of playing MUSIC (MUSIC _ pay) corresponds may be (wait _ key, MUSIC _ term, MUSIC _ singer, MUSIC _ name, MUSIC _ tag).
And then generating a sample slot position subset group corresponding to the sample slot position set.
For example, the sample slot subset group corresponding to the sample slot set (wait _ key, music _ term, music _ range, music _ name, music _ tag) may include the following 31 sample slot subsets: (wait _ key, music _ term, music _ range, music _ name, music _ tag), (wait _ key, music _ term, music _ range, music _ name), (wait _ key, music _ term, music _ name, music _ tag), (wait _ key, music _ range, music _ name, music _ tag), (music _ term, music _ range, music _ name, music _ tag), (wan _ key, music _ term, music _ range), (wan _ key, music _ term, music _ name), (wan _ key, music _ range, music _ tag), (wan _ key, music _ name, music _ tag), (music _ term, music _ range, music _ name, music _ term, music _ name, music _ tag), (music _ range, music _ name, music _ tag), (water _ key, music _ term), (water _ key, music _ index), (water _ key, music _ name), (water _ key, music _ tag), (music _ term, music _ singer), (music _ term, music _ name), (music _ term, music _ tag), (music _ singer, music _ name), (music _ name, music _ tag), (water _ key), (music _ term), (music _ singer), (music _ name), (music _ tag).
Then, for a sample slot subset in the sample slot subset group, the frequency of the sample slots in the sample slot subset is counted.
In general, the execution subject may count the frequency of occurrence of the sample slot position subset in the sample slot position annotation text set as the frequency of the sample slot position in the sample slot position subset. The frequency of the sample slot position subsets including one sample slot position in the sample slot position labeling text set is the frequency of the sample slot position, and the frequency of the sample slot position subsets including a plurality of sample slot positions in the sample slot position labeling text set is the frequency of the sample slot position combination.
And finally, determining the sample slot position with the frequency greater than a preset frequency threshold value in the sample slot position subset as a core sample slot position.
In general, if the frequency of occurrence of a sample slot position subset including one sample slot position in the sample slot position annotation text set is that the frequency of occurrence of the sample slot position is greater than a preset frequency threshold, the sample slot position is a core sample slot position. If the frequency of the sample slot position subset comprising the plurality of sample slot positions appearing in the sample slot position labeling text set is greater than a preset frequency threshold, all the sample slot positions in the sample slot position subset are core sample slot positions.
In addition, only sample slots that appear in the set of sample slots to which the sample is intended may also be determined to be core sample slots. And a sample slot that appears in a plurality of sample slot sets to which the plurality of samples are intended cannot be determined as a core sample slot. For example, the sample text "do you like jazz MUSIC" corresponding to the sample intention of CHAT (CHAT) also appears at the sample slot MUSIC _ tag, so the sample slot MUSIC _ tag cannot be used as the core sample slot corresponding to the sample intention of play MUSIC (MUSIC _ pay).
In some optional implementations of this embodiment, the execution body may determine, as the non-core sample slot, a sample slot in the sample slot set except for the core sample slot.
In this embodiment, the execution subject may generate the triplet based on the sample intent, the core sample slot, and the non-core sample slot. For example, the sample intent MUSIC _ poly, the core sample slots wait _ key and MUSIC _ term, and the non-core sample slots MUSIC _ singer, MUSIC _ name and MUSIC _ tag may constitute a triplet (MUSIC _ poly, wait _ key/MUSIC _ term, MUSIC _ singer/MUSIC _ name/MUSIC _ tag).
The method for generating the information comprises the steps of firstly obtaining a sample slot position marking text set corresponding to a sample intention; then counting the occurrence condition of each sample slot in the sample slot labeling text set, and determining a core sample slot and a non-core sample slot corresponding to the sample intention; and finally generating the triples based on the sample intention, the core sample slot positions and the non-core sample slot positions. A large amount of data do not need to be accumulated additionally, the features can be extracted only by using the intention and the slot position labeling samples, and the workload of feature extraction is reduced. In addition, the sample extraction features are marked on the basis of the intents and the slots, so that the extracted triple features are strongly related to the intents and the slots, and the relevance of the extraction features to the intents and the slots is improved.
With further reference to FIG. 3, a flow 300 of yet another embodiment of a method for generating information in accordance with the present application is illustrated. The method for generating information comprises the following steps:
In this embodiment, the specific operations of steps 301 to 303 are already described in detail in steps 201 to 203 in the embodiment shown in fig. 2, and are not described again here.
And 304, regarding a sample slot position labeling text in the sample slot position labeling text set, taking the sample text and the triple corresponding to the sample slot position labeling text as input, taking the sample intention and the sample slot position labeling text as output, and training a deep neural network to obtain an intention and slot position identification model.
In this embodiment, for a sample slot annotation text in a sample slot annotation text set, an execution subject (for example, the server 103 shown in fig. 1) of the method for generating information may take a sample text and a triplet corresponding to the sample slot annotation text as inputs, take a sample intention and the sample slot annotation text as outputs, train a deep neural network, and obtain an intention and slot identification model. Wherein, the deep neural network may be a bidirectional LSTM (Long Short-Term Memory network). In the model training stage, not only the intention and slot position marking samples are used, but also the extracted triple features based on the intention and slot position marking samples are used, the extracted triple features are strongly related to the intention and the slot position, and the recognition effect of the trained model on the intention and the slot position is improved.
As can be seen from fig. 3, the flow 300 of the method for generating information in the present embodiment adds a model training step compared to the embodiment corresponding to fig. 2. Therefore, in the scheme described in this embodiment, not only the intention and slot position labeling samples are used in the model training stage, but also the extracted triple features based on the intention and slot position labeling samples are used, and the extracted triple features are strongly related to the intention and the slot position, so that the recognition effect of the trained model on the intention and the slot position is improved.
With further reference to FIG. 4, a flow 400 of another embodiment of a method for generating information according to the present application is shown. The method for generating information comprises the following steps:
In this embodiment, the specific operations of steps 401 to 404 have been described in detail in steps 301 to 304 in the embodiment shown in fig. 3, and are not described again here.
In the present embodiment, an execution subject (e.g., the server 103 shown in fig. 1) of the method for generating information may receive a voice to be recognized input by a user. The voice to be recognized can be the voice input by the user in the process of man-machine interaction.
In this embodiment, the execution subject may convert the speech to be recognized into the text to be recognized. Specifically, the execution main body may perform speech recognition on the speech to be recognized to obtain a corresponding text to be recognized.
In this embodiment, the executing body may input the text to be recognized to the intention and slot recognition model for classification and sequence labeling, so as to obtain an intention and slot labeled text corresponding to the text to be recognized.
Usually, a possible intent is triggered only when a core slot is present in the text to be recognized. The combination of the core slot and the non-core slot that triggers the intent is the possible slot. For example, for the text to be recognized "play zhangjie jazz MUSIC", the intention MUSIC _ pay may be triggered by the triplet (MUSIC _ pay, wait _ key/MUSIC _ term, MUSIC _ singer/MUSIC _ name/MUSIC _ tag), and the jazz [ MUSIC _ tag ] MUSIC [ MUSIC _ term ] whose slot is labeled text play [ wait _ key ] zhangjie [ MUSIC _ singer ].
As can be seen from fig. 4, the flow 400 of the method for generating information in the present embodiment adds a model prediction step compared to the embodiment corresponding to fig. 3. Therefore, according to the scheme described in the embodiment, the text to be recognized is directly input to the intention and slot recognition model for classification and sequence labeling, and the intention and slot labeling text corresponding to the text to be recognized can be obtained. And under the condition that the recognition effect of the intention and slot position recognition model is improved, the intention and slot position accuracy of the recognized text to be recognized is also improved.
