FIG. 2 is a schematic diagram of a compilation module according to an embodiment of the present invention. Referring to FIG. 1 and FIG. 2, the compilation module 210 includes a built-in sentence template 211, and the built-in sentence template 211 may be, for example, a command sentence template or a control sentence template, and these sentences are generally used to represent the same semantic meaning. Different sentence patterns of the sentence, for example, multiple templates described in the following examples are multiple different command sentence patterns for expressing the same semantic meaning, but the present invention is not limited thereto. The built-in sentence template 211 includes a plurality of formal parameters, and these formal parameters include a verbal phrase parameter 212_1 and a nominal phrase parameter 2122. However, the number of verbal phrase parameters 212_1 and nominal phrase parameters 212_2 in the built-in sentence template 211 is not limited by the present invention, and the built-in sentence template 211 is not limited to verb parameters or noun parameters. In this In the embodiment, the input device 120 provides phrase data 220 and semantic data 230, so that the compilation module 210 combines the phrase data 220 and semantic data 230 with a built-in sentence template 211 to generate grammatical expression data 240.

In this embodiment, the phrase data 220 includes verb phrase data 221 and noun phrase data 222. The verb phrase data 220 may include multiple verb actual parameters, and the noun phrase data may include multiple noun actual parameters, where these verb actual parameters and noun actual parameters are usually used to represent multiple nouns or verbs with synonyms. In this embodiment, the semantic data 230 includes character string data, and the character string data includes modifier symbols and semantic words. In this embodiment, when the processor 110 combines phrase data 220 and semantic data 230 with a built-in sentence template 211 to generate grammatical expression data 240, the processor 110 combines at least one of the actual parameters of these verbs and At least one of the actual parameters of these nouns is associated with the formal parameters in the built-in sentence template 211 to generate grammatical expression data 240. In this embodiment, the syntax expression data 240 may include one or more syntax expressions. Therefore, when the processor 110 performs a natural language understanding operation, the processor 110 may generate a plurality of grammatical rule data by using the grammatical expression data 240, and compare the corpus data with the grammatical rule data to obtain a corresponding Corpus data semantic information.

For example, the built-in sentence template 211 includes the following multiple templates, for example.

The first template is "<_basic sentence pattern: template>: [= verbal phrase, noun phrase =] [Please] $ (verbal phrase) $ (noun phrase)".

The second template is "<_ 把 词句 ： template>: [= verbal phrase, noun Sexual Phrase =] [Please] put $ (noun phrase) $ (verbal phrase) ".

The third template is "<_ 帮忙 _ 动 宾 struct: template>: [= verbal phrase, noun phrase =] [Please] [帮] 帮帮 $ (verbal phrase) $ (noun phrase) ｜ $ (noun phrase) [Please] [帮] 帮帮 $ (verbal phrase) ｜ [Please] (帮 [帮] ｜ Help) (我 ｜ 俺) $ (verbal phrase) $ (nominal Phrase) "｜ $ (Noun Phrase) [Please] (帮 [帮] ｜ Help) (我 ｜ $) $ (verbal phrase) ｜ [Please] (Give ｜ to) (我 ｜ 俺) $ (Verbal phrase) $ (noun phrase) | $ (noun phrase) [please] (give ｜ to) (我 ｜ 俺) $ (verbal phrase) ".

Take the first template for illustration, "<_basic sentence: template>" represents the definition of a template, where "template" is a keyword, and the name of this template is "_basic sentence". "[= Verbal phrase, nominal phrase =]" is the parameter description of this template, and the two parameters described here are verbal phrase and noun phrase. "[Please] $ (verbal phrase) $ (noun phrase)" is the definition of this template. The symbol "$" is a keyword and is used to refer to a formal parameter. The symbol "|" is used to indicate "or". In this example, the compiled contents of the language symbols of these templates are generated according to the metalanguage symbolic representation of the Extended Backus-Naur Form (EBNF).

Therefore, in this example, the user can input the phrase data 220 and the semantic data 230 to the compilation module 210 through the input device 120. In this example, the content of the phrase data 220 may be, for example, "<verb phrase 1>: start | open | open | open | open | open | open" and "<noun phrase 1>: air conditioner". The semantic data 230 includes character string data, and the content of the character string data may be, for example, "<{@ = openconditioner}>", where "@" Is a modifier and "openconditioner" is a semantic word. In this example, the compiling module 210 can generate the following multiple grammars corresponding to the first to third templates respectively according to the phrase data 220 and semantic data 230.

The first grammar is "<grammar_basic sentence pattern_1>: <_ basic sentence pattern (<verb phrase 1>, <noun phrase 1>)> <{@ = openconditioner}>".

The second grammar is "<grammar_ 把 字句 _1>: <_ 把 字句 (<verb phrase1>, <noun phrase1>)> <{@ = openconditioner}>".

The third grammar is "<grammar_ 帮帮 _ 动 宾 结构 _1>: <_ 帮帮 _ 动 OB structure (<verb phrase 1>, <noun phrase 1>)> <{@ = openconditioner}>".

Take the first grammar as an example, "<grammar_basic sentence pattern 1>" is the name of the grammar. "<_Basic sentence pattern (<verb phrase 1>, <noun phrase 1>)>" means that the first template "<_basic sentence pattern>" is called, and the actual parameters passed to the first template at the same time are <verb phrase 1 > And <noun phrase 1>. "<@ = Openconditioner>" is represented as a modifier. That is, if the first grammar matches the corpus data, an "openconditioner" is output to represent the semantics.

Therefore, in this example, the compiling module 210 may combine the first to third templates with the first to third grammars to generate grammatical expression data 240. When the electronic device 100 performs a natural language understanding operation, the processor 110 may obtain a plurality of grammatical rules according to the grammatical expression data 240. In this example, the corpus data provided by the input device 120 may be, for example, “Please turn on the air conditioner”, “Please turn on the air conditioner”, and “Please turn on the air conditioner for me”. Therefore, the processor 110 may match the corpus "Please turn on the air conditioner" to the grammar "<grammar_basic sentence pattern 1>" and output semantic information "Openconditioner". The processor 110 may match the corpus "Please turn on the air conditioner" to the grammar "<grammar_ 把 字句 _1>" and output the semantic information "openconditioner". The processor 110 may match the corpus "Please turn on the air conditioner for me" to the grammar "<grammar_ 帮帮 _ 动 宾 结构 _1>" and output the semantic information "openconditioner". Accordingly, the user can generate a plurality of syntaxes according to the syntax compiling system 10 of the present invention without compiling any syntax rules. In addition, the user can determine the phrase content and the number of phrases of the phrase data 220 according to different needs, and is not limited to the above examples.

FIG. 3 is a flowchart of a syntax compiling method according to an embodiment of the present invention. Referring to FIG. 1 to FIG. 3, the syntax compiling method of this embodiment is applicable to at least the syntax compiling system 10 of FIGS. 1 and 2. In step S310, the electronic device 100 executes the compilation module 210, and reads a built-in sentence template 211 in the compiled module 210. The built-in sentence template 211 includes a plurality of formal parameters, and the compiled module 210 has syntax Compile platform. In step S320, the electronic device 100 receives the phrase data 220 and the semantic data 230 via the input device 120. The compilation module 210 combines the phrase data 220 and the semantic data 230 with the built-in sentence template 211 to generate grammatical expression data 240. The grammatical expression data 240 can be used to generate multiple grammars. That is, the grammar compiling method of this embodiment can directly combine the phrase data 220 and semantic data 230 input by the user with the built-in sentence template 211 to quickly and conveniently generate the grammatical expression data 240. Therefore, the syntax compiling method of this embodiment can effectively save the workload of compiling the syntax.

In addition, the relevant device features and technical contents of the syntax compiling system 10 of this embodiment can be obtained based on the contents of the embodiments of FIG. 1 and FIG. 2 described above. Instructions, recommendations, and implementation instructions, so I wo n’t repeat them.
