FIG. 1 is a diagram illustrating an example of a hardware configuration of an information processing apparatus (computer). As illustrated in FIG. 1, the information processing apparatus 1 includes a CPU 11, an input device 12, a storage device 13, and a display device 14 as a hardware configuration.
The CPU 11 implements functions provided by the information processing apparatus 1 by executing processing based on a program stored in the storage device 13 including RAM, ROM, HD, and the like. The input device 12 is a mouse, a keyboard, or the like, for example, and inputs information to the information processing device 1 according to an operation of an administrator or the like. The display device 14 is a display or the like, for example, and displays a result of processing in the information processing device 1. The storage device 13 stores programs, data necessary for the processing of the CPU 11, and the like.
The input device 12 is not an essential hardware configuration of the information processing device 1.

<Embodiment 1>
FIG. 2 is a diagram illustrating an example of a functional configuration of the information processing apparatus according to the first embodiment.
As illustrated in FIG. 2, the information processing apparatus 1 according to the first embodiment includes, as functional configurations, a morphological analysis unit 21, a dependency unit 22, a case frame acquisition unit 23, a determination unit 24, and an output unit 25. ,including. It is assumed that the morpheme dictionary 31, grammar rule dictionary 32, case frame dictionary 33, and thesaurus dictionary 34 are stored in the storage device 13. However, the above-described dictionary is not necessarily stored in the storage device 13, and may be stored in a device that can be referred to via the network by the information processing device 1.
The morpheme analysis unit 21 uses the morpheme dictionary 31 to perform a morpheme analysis of a sentence included in the target document and divide the sentence into morphemes. For example, as shown in FIG. 3, the morphological analysis unit 21 “executes a test at a fixed time”
The sentence "on time""server""test""execute"
And divide into each morpheme. The morpheme dictionary 31 is a dictionary that collects morpheme information for Japanese vocabulary.

The dependency unit 22 uses the grammar rule dictionary 32 to analyze the dependency between morphemes constituting the sentence divided by the morpheme analysis unit 21. For example, as shown in FIG. 4, the dependency receiving unit 22 analyzes the dependency between morphemes and outputs an analysis result (what each morpheme is related to). The grammar rule dictionary 32 is a dictionary in which information on Japanese grammar is described.
The case frame acquisition unit 23 acquires a frame corresponding to the predicate (predicate) from the case frame dictionary 33 as a result of the analysis by the dependency unit 22. For example, the case frame acquisition unit 23 acquires a case frame “execute” as a predicate from the case frame dictionary 33.
Here, as shown in FIG. 5, the case frame of “execute”
“N1 executes N2”
N1 and N2 are called case slots (or slots).
In addition, as shown in FIG.
"N1 (machine / subject) N2 (abstract)"
This is a case slot constraint.
For example, N1 (machine / subject) indicates that N1 is a subject and a noun having a semantic feature (meaning belonging to a lower level of the machine) below the machine.

The determination unit 24 has a morpheme satisfying the restriction of the case slot included in the case frame acquired by the case frame acquisition unit 23 among the plurality of morphemes constituting the sentence divided into morphemes by the morpheme analysis unit 21. Whether or not an ambiguous expression that causes misunderstanding exists in the sentence is determined based on the result of the determination. Here, the thesaurus dictionary 34 is a dictionary in which words are hierarchized and arranged in meaning.
For example, the thesaurus dictionary 34
It has information such as noun>concrete>concrete>inanimate>artifact>machine> electrical equipment> computer, etc. and computer and server have synonyms.
Therefore, for example, the determination unit 24 “executes” “executed” “on time” “server” as shown in FIG.
Among them, it is determined that “server” corresponds to N1.
The thesaurus dictionary 34
Noun>Abstract>Things> Human Activity>Mental>Thinking> Survey / Research>Examination> We have information such as tests.
Therefore, for example, the determination unit 24 “executes” “executed” “on time” “server” as shown in FIG.
It is determined that “test” corresponds to N2.

As described above, the sentence is “scheduled” “server” “test” “execute” as shown in FIG.
In this case, the determination unit 24 can determine that the “server” corresponds to N1.
However, the sentence is “on time” “test” “execute” as shown in FIG.
In this case, the determination unit 24 determines that there is no morpheme (or noun) corresponding to N1 in the sentence using the “execute” case frame and the thesaurus dictionary 34 as shown in FIG. A NULL (zero pronoun) is inserted in the “N1 is” part. In the present embodiment, NULL is used to represent zero pronouns, but this does not limit the present embodiment.
Similarly, for example, the sentence is “on time” “server” “execute”
In this case, the determination unit 24 determines that there is no morpheme (or noun) corresponding to N2 in the sentence using the “execute” case frame and the thesaurus dictionary 34 as shown in FIG. Insert NULL (zero pronoun) in the “N2” part.
For example, in the case of a sentence that does not satisfy the restriction of the case slot as shown in FIG. 6, the determination unit 24 determines that there is an ambiguous expression that causes misunderstanding in the sentence.
When the determination unit 24 determines that there is an ambiguous expression that causes misunderstanding in the sentence, the output unit 25 displays, for example, on the display device 14 that the sentence has an ambiguous expression. The output unit 25 may output, for example, a voice indicating that an ambiguous expression is present, for example, in addition to outputting to the display device 14 that an ambiguous expression is present in the sentence. Good.

(Disqualification judgment)
If cases such as the main case (subject) and the target case (object) are omitted, there is a possibility that multiple interpretations are generated. Therefore, in the following, the information processing apparatus 1 determines whether or not a case is omitted in a sentence, and when ambiguity occurs due to the case being omitted, a process of displaying a message indicating that fact Will be explained.
FIG. 7 is a flowchart illustrating an example of the case omission determination process.
In step S <b> 10, the determination unit 24 determines whether the following inspection has been performed on all the sentences included in the target document. When the determination unit 24 performs the following inspection on all the sentences included in the target document, the determination unit 24 ends the process illustrated in FIG. 7 and performs the following on all the sentences included in the target document. If such inspection is not executed, the process proceeds to step S11.
In step S11, the determination unit 24 determines whether a zero pronoun exists in the sentence to be processed. The determination unit 24 advances the process to step S12 when the zero pronoun exists in the sentence to be processed, and returns the process to step S10 when the zero pronoun does not exist in the sentence to be processed.
In step S12, the determination unit 24 acquires a case slot constraint corresponding to the zero pronoun. For example, in the case of a sentence as shown in FIG. 6, the determination unit 24 acquires a case slot restriction of N1 (machine / subject) based on a case frame as shown in FIG.

In step S13, the determination unit 24 uses the thesaurus dictionary 34 to select a noun having a semantic feature that satisfies the restriction of the case slot acquired in step S12, for example, the sentence before the sentence to be processed (or the process target). Search (forward search) before the position where the zero pronoun of the sentence exists. If it demonstrates using the example mentioned above, the judgment part 24 will search the noun which has the semantic feature below a machine using the thesaurus dictionary 34, for example from the sentence before the said process target sentence (forward search). Note that the determination unit 24, for example, within the range of the setting (for example, within 3 sentences including the processing action sentence, and zero of the processing action sentence according to the setting of the setting file stored in the storage device 13 or the like. Perform a search with up to 50 words including pronouns.
In step S14, the determination unit 24 determines whether there are two or more nouns having semantic features that satisfy the restriction of the case slot acquired in step S12 as a result of the forward search in step S13. When there are two or more nouns, the determination unit 24 proceeds to step S15. When there are two or more nouns, the determination unit 24 returns the process to step S10.
Here, for simplification of description, the description is made with two or more, but the determination unit 24 may determine whether there are N or more nouns. N is an arbitrary natural number of 1 or more set in the setting file or the like.
However, in this embodiment, for the sake of simplicity of explanation, the case where N = 2 is set as the default setting value will be described as an example. This is because, when N = 1, for example, even if the sentence has no subject, it may be understood naturally without ambiguity as Japanese. In the following, similarly, the case where N = 2 will be described as an example.
In step S15, the output unit 25 displays, for example, on the display device 14 that there is an ambiguous expression in the sentence. Note that the output unit 25 may clearly indicate which sentence is ambiguous in the target document including a plurality of sentences, and display that the sentence has an ambiguous expression. . Note that the output unit specifies the sentence by changing the font size of the sentence, changing the font color of the sentence, or underlining the sentence, for example. The same applies to the following.
By the process shown in FIG. 7, when there are a plurality of noun candidates that fit the omitted case in the target document, it can be pointed out to the user that there is an ambiguous expression (an ambiguous abbreviated expression).

(Indicator determination-things)
An instruction word whose destination is unclear may cause multiple interpretations. Therefore, in the following, the information processing apparatus 1 determines whether or not there is an instruction word (this, that, that) representing an object in a sentence, and there are a plurality of instruction destinations of the instruction word in a document including the sentence. Then, when there are a plurality of instruction destinations of the instruction word, a process for displaying a message indicating that will be described.
FIG. 8 is a diagram illustrating an example of a sentence including an instruction word representing a thing.
FIG. 9 is a flowchart illustrating an example of the instruction word determination process for things.
In step S <b> 20, the determination unit 24 determines whether the following inspection has been performed on all the sentences included in the target document. When the determination unit 24 performs the following inspection on all of the sentences included in the target document, the determination unit 24 ends the process illustrated in FIG. 9 and performs the following on all of the sentences included in the target document. If such inspection is not executed, the process proceeds to step S21.
In step S <b> 21, the determination unit 24 determines whether or not an instruction word for an object exists in the sentence to be processed. The determination unit 24 advances the process to step S22 when the instruction word for the object exists in the sentence to be processed, and returns the process to step S20 when the instruction word for the object does not exist in the sentence to be processed.
In step S <b> 22, the determination unit 24 acquires a case slot constraint corresponding to the instruction word of the thing. For example, in the case of the sentence as shown in FIG. 8, the determination unit 24 uses N1 (machine / subject) as the restriction of the case slot corresponding to the instruction word (this) based on the case frame as shown in FIG. get.

In step S23, the determination unit 24 uses the thesaurus dictionary 34 to search for a noun having a semantic feature that satisfies the restriction of the case slot acquired in step S22 from, for example, a sentence before the sentence to be processed (forward search). ) If it demonstrates using the example mentioned above, the judgment part 24 will search the noun which has the semantic feature below a machine using the thesaurus dictionary 34, for example from the sentence before the said process target sentence (forward search). Note that the determination unit 24, for example, within the range of the setting (for example, within 3 sentences including the processing action sentence, and zero of the processing action sentence according to the setting of the setting file stored in the storage device 13 or the like. Perform a search with up to 50 words including pronouns.
In step S24, the determination unit 24 determines whether there are two or more nouns having semantic features that satisfy the restriction of the case slot acquired in step S22 as a result of the forward search in step S23. When there are two or more nouns, the determination unit 24 proceeds to step S25. When there are two or more nouns, the determination unit 24 returns the process to step S20.
In step S25, the output unit 25 displays, for example, on the display device 14 that there is an ambiguous expression in the sentence. Note that the output unit 25 may clearly indicate which sentence is ambiguous in the target document including a plurality of sentences, and display that the sentence has an ambiguous expression. .
The processing shown in FIG. 9 can indicate to the user that there is an ambiguous expression (an ambiguous instruction expression) when there are a plurality of instruction destinations of instruction words representing things in the target document.

(Disagreement judgment)
If the subject and predicate do not match, multiple interpretations can occur. Therefore, in the following, a process will be described in which the information processing apparatus 1 determines whether or not the subject and predicate included in the sentence match, and if they do not match, displays a message indicating that fact.
FIG. 10 is a diagram illustrating an example of a sentence in which the subject and the predicate do not match.
As shown in FIG. 10, the “software package”, “presentation application”, “collectively”, and “install”
In this case, the case frame acquisition unit 23 acquires the case frame “install” from the case frame dictionary 33 as a predicate. Here, as shown in FIG. 10, the “install” case frame includes
“N1 installs N2”
It is described.
Also, as shown in FIG.
"N1 (machine / subject) N2 (abstract)"
This is a limitation of the case slot as described above.

FIG. 11 is a flowchart illustrating an example of the mismatch determination process.
In step S <b> 30, the determination unit 24 determines whether the following inspection has been performed on all the sentences included in the target document. When the determination unit 24 performs the following inspection on all the sentences included in the target document, the determination unit 24 ends the process illustrated in FIG. 11 and performs the following on all the sentences included in the target document. When such an inspection is not executed, the process proceeds to step S31.
In step S <b> 31, the determination unit 24 determines whether or not the “ga rating” noun that modifies the predicate of the sentence to be processed satisfies the restriction of the “ga rating” case slot of the case frame. If the noun of “ga case” that modifies the predicate of the sentence to be processed satisfies the restriction of the case slot of “ga case” in the case frame, the determination unit 24 returns to the process of step S30 and returns the predicate of the sentence to be processed. If the noun of “ga case” that modifies the case does not satisfy the restriction of the case slot of “ga case” of the case frame, the process proceeds to step S32.
In the case of the example in FIG. 10, since there is no “ga” noun that modifies the predicate in the sentence to be processed, the determination unit 24 advances the process to step S <b> 32.

In step S <b> 32, the determination unit 24 determines whether or not the “Category” noun that modifies the predicate of the processing target statement satisfies the restriction of the case frame “Ga” case slot. If the noun of “Category” that modifies the predicate of the sentence to be processed satisfies the restriction of the case slot of the “case” in the case frame, the determination unit 24 returns to the process of step S30 and returns the predicate of the sentence to be processed. If the noun of “Category” that modifies “Case” does not satisfy the restriction of the case slot of “Case” of the case frame, the process proceeds to step S33.
In the case of the example of FIG. 10, the noun of “Case” that modifies the predicate in the statement to be processed is “Software Package”, and the restriction of the case slot of “Ga Case” in the case frame is N1 (machine / Therefore, the determination unit 24 determines that the restriction of the case slot is not satisfied, and proceeds to step S33.
The output unit 25 displays, for example, on the display device 14 that an ambiguous expression exists in the sentence. Note that the output unit 25 may clearly indicate which sentence is ambiguous in the target document including a plurality of sentences, and display that the sentence has an ambiguous expression. .
With the processing shown in FIG. 11, when a sentence in which the subject and the predicate do not match exists in the target document, it can be pointed out to the user that an ambiguous expression exists.

Accordingly, in the following, the information processing apparatus 1 indicates whether or not there is an instruction word (a person, person, or person) representing a person (person) in a sentence, and there are a plurality of instruction destinations of the instruction word in a document including the sentence. When there are a plurality of instruction destinations of the instruction word, a process for displaying a message indicating that will be described.
FIG. 14 is a flowchart illustrating an example of a personal instruction word determination process.
In step S <b> 50, the determination unit 42 determines whether the following inspection has been performed on all the sentences included in the target document. When the determination unit 42 performs the following inspection on all the sentences included in the target document, the determination unit 42 ends the process illustrated in FIG. 14 and performs the following on all the sentences included in the target document. If the inspection as shown in FIG. 6 is not executed, the process proceeds to step S51.
In step S51, the determination unit 42 determines whether or not a personal instruction word exists in the sentence to be processed. The determination unit 42 proceeds with the process to step S52 when the personal instruction word is present in the sentence to be processed, and returns the process to step S50 when the personal instruction word does not exist in the sentence to be processed.

In step S <b> 52, the determination unit 42 uses the thesaurus dictionary 34 to search (forward search) for a noun having a semantic feature equal to or less than that of a person, for example, from a sentence before the sentence to be processed. For example, the determination unit 42 is within the range of the setting (for example, within 3 sentences including the sentence to deal with processing, and the personality of the sentence to deal with processing according to the setting of the setting file stored in the storage device 13 or the like. The search is executed within 50 words including the instruction word.
In step S53, the determination unit 42 determines whether or not there are two or more nouns having a semantic feature equal to or less than a person as a result of the forward search in step S52. When there are two or more nouns, the determination unit 42 proceeds to step S54. When there are two or more nouns, the determination unit 42 returns the process to step S50.
