- the example in Figure 9 shows one sample SMP11 included in the first prompt, the number of samples included in the first prompt may be multiple.
- the query included in the first prompt includes specified context data for the first item "INDUSTRIY", but includes only the item name for the second item "STEEP” and does not include a natural language sentence following the item name.

- the samples included in the second prompt include sample SMP21.
- Sample SMP21 includes the first relationship knowledge data D13 shown in FIG. 7 as the first item "INDUSTRIY", the second item “CAUSE", and the third item "EFFECT".
- the first relationship knowledge data D13 for generating sample SMP21 may be extracted from the first relationship knowledge dataset by the second generating unit 15A.
- the extraction process may be performed randomly, or may extract data that satisfies a predetermined condition.
- the predetermined condition may be a condition based on the score, the generation date and time, past extraction history, etc.
- the process of generating the second prompt in step S104 may be executed individually for each piece of second antecedent data included in the second antecedent data list, or may be executed once for some or all of the multiple pieces of second antecedent data.
- the samples included in the second prompt generated for each piece of second antecedent data may be different from each other. This reduces bias in the content of the samples, making it possible to generate a greater variety of second consequent data. Note that, although the example in FIG. 11 shows one sample SMP21 included in the second prompt, the number of samples included in the second prompt may be multiple.
- the query included in the second prompt includes the second context data as the first item "INDUSTRIY” and the second antecedent data as the second item "CAUSE". Meanwhile, the query includes only the item name as the third item "EFFECT" and does not include a natural language sentence following the item name.
- Such a query indicates a request to generate a natural language sentence indicating "EFFECT" that corresponds to the context "fishing" indicated by the second context data and the second antecedent data "The use of robots".
- step S105 the second generation unit 15A generates second consequent data corresponding to the second context data and the second antecedent data by inputting the generated second prompt into the language model 3A.

As shown in FIG. 12, the second relational knowledge data set includes second relational knowledge data D21, D22, .... When there is no need to particularly distinguish between them, each of them is also described as second relational knowledge data D2.
- the second relational knowledge data D2 includes second context data, second antecedent data, and second consequent data.
- the second relational knowledge data set is configured by adding a column of "second consequent data" to the second antecedent data list shown in FIG. 10. Since the second relational knowledge data D2 is generated by the language model 3A using the first relational knowledge data D1 as a sample, it is highly likely that the second relational knowledge data D2 has a "specific relationship” like the first relational knowledge data D1, but does not necessarily have a "specific relationship”. Therefore, the subsequent steps S106 to S108 are executed to perform processing according to the relationship contained in the second relationship knowledge data.
- Steps S106 to S108 Determine the relationship contained in the second relationship knowledge data
- Steps S106 to S108 will be described with reference to Figures 4 and 6 again.
- the determination unit 16A determines whether the relationship held by each piece of second relationship knowledge data is a "specific relationship,” a "different relationship,” or an “other relationship” by using the language model 3A.

- the "different relationship” may be a relationship in which the context is not specified, such as a "synonymous relationship" or an "implication relationship".
- a relationship in which the context is not specified is a relationship in which the "different relationship” holds even if the third antecedent data and the third consequent data are swapped.
- the "different relationship” is not limited to this, and may also be a relationship in which the context is specified.
- FIG. 13 is a diagram showing a specific example of the third relational knowledge dataset.
- the third relational knowledge dataset includes third relational knowledge data D31, D32, D33, ....

- the third instruction data includes information to be generated by the third prompt, including the first item "INDUSTRY”, the second item “SENTENCE1", the third item “SENTENCE2”, and the fourth item "Label”, as well as natural language sentences explaining the definitions of each item.
- the third instruction data includes a natural language sentence that explains that "e” indicates a different relationship and "x" indicates that the relationship is not different, as the definition of the fourth item "Label”.
- the samples included in the third prompt include a negative example sample SMP31 and a non-negative example sample SMP32.
- the negative example sample SMP31 includes the third relationship knowledge data D31 shown in FIG. 13 as the first to third items, and includes "e” as the fourth item "Label".
- e is a label indicating "different relationship”.
- the non-negative example sample SMP32 includes the first relationship knowledge data D12 shown in FIG. 7 as the first to third items, and includes "x" as the fourth item "Label”.
- "x" is a label indicating "not a different relationship”.
- the third relationship knowledge data D31 for generating the negative example sample SMP31 may be extracted from the third relationship knowledge dataset by the determination unit 16A.
- the first relationship knowledge data D12 for generating the non-negative example sample SMP32 may be extracted from the first relationship knowledge dataset by the determination unit 16A.
- the extraction process may be performed randomly, or data that satisfies a specified condition may be extracted.
- the specified condition may be a condition based on the score, the generation date and time, past extraction history, etc.
- the process of generating the third prompt in step S106 may be performed individually for each piece of second relationship knowledge data included in the second relationship knowledge data set, or may be performed once in common for some or multiple pieces of second relationship knowledge data.
- the samples included in the third prompt generated for each piece of second relationship knowledge data may be different from each other. This reduces bias in the content of the samples, making it possible to more accurately determine whether or not they are negative examples.
- one negative example sample SMP31 included in the third prompt is shown, but the number of negative example samples included in the third prompt may be multiple.
- one non-negative sample SMP32 included in the third prompt is shown, but the number of non-negative samples included in the third prompt may be multiple.
- the query included in the third prompt includes the second relational knowledge data as the first to third items, but includes only the item name as the fourth item, "Label," and does not include a natural language sentence following the item name.
- Such a query indicates a request to generate a natural language sentence indicating "Label" that corresponds to the second relational knowledge data included in the query.
- step S107 the determination unit 16A inputs the generated third prompt into the language model 3A to determine whether or not each piece of second relationship knowledge data included in the second relationship knowledge data set is a negative example. For example, the determination unit 16A determines that the second relationship knowledge data in which "e” is generated as the "Label” is a negative example (i.e., has a "different relationship”). Also, for example, the determination unit 16A determines that the second relationship knowledge data in which "x" is generated as the "Label” is not a negative example (i.e., does not have a different relationship).
- step S108 the determination unit 16A determines whether the second relationship knowledge data determined in step S107 to be not a negative example is a positive example or a negative example based on further input from the user.
- the user may input, for example, annotation information indicating whether the second relationship knowledge data determined to be not a negative example is a positive example having a specific relationship, a negative example having a different relationship, or something else. This makes it possible to identify "positive examples having a specific relationship" with greater accuracy than when all second relationship knowledge data determined by the language model 3A to be "not negative examples" are treated as positive examples.
- each piece of second relationship knowledge data included in the second relationship knowledge dataset is classified as a positive example or a negative example.
- the second relationship knowledge data classified as a positive example is determined not to be a negative example by the language model 3A and selected by the user to be a positive example.
- the second relationship knowledge data classified as a negative example includes data determined to be a negative example by the language model 3A.
- the second relationship knowledge data classified as a negative example may include data determined not to be a negative example by the language model 3A but selected by the user to be a negative example.
- Steps S109 to S111 will be described with reference to Figures 4 and 6 again.
- Steps S109 to S111 are steps for updating the first relationship knowledge data set, the third relationship knowledge data set, and the relationship knowledge database 2A.
- the second relationship knowledge data classified as a positive example is used to update the first relationship knowledge data set and the relationship knowledge database 2A.
- the second relationship knowledge data classified as a negative example is used to update the third relationship knowledge data set.
- step S109 the update unit 13A updates the third relationship knowledge dataset using the second relationship knowledge data classified as a negative example from the second relationship knowledge dataset.
- Updating the third relationship knowledge dataset may mean, for example, adding the second relationship knowledge data classified as a negative example to the third relationship knowledge dataset as new third relationship knowledge data.
- updating the third relationship knowledge dataset may mean, for example, replacing part or all of the third relationship knowledge dataset with the second relationship knowledge data classified as a negative example as new third relationship knowledge data.
- the language model 3A may output a score indicating the appropriateness of the fourth item "Label" generated for each piece of second relationship knowledge data in response to the third prompt.
- the update unit 13A may update the third relationship knowledge dataset using the second relationship knowledge data classified as negative examples whose scores satisfy a predetermined condition (e.g., the score is equal to or greater than a threshold, the score is within a predetermined rank from the top, within a predetermined percentage, etc.).
- the update unit 13A may update the third relationship knowledge dataset using the second relationship knowledge data classified as negative examples that is selected by the user.
- step S109 the first relational knowledge dataset that is referenced the next time information processing method S1A is repeated is updated, improving the accuracy of the second prompt generated based on the first relational knowledge dataset. As a result, the accuracy of the generated second relational knowledge data as a positive example is improved.
- step S110 the update unit 13A updates the first relationship knowledge dataset using the second relationship knowledge data classified as a positive example from the second relationship knowledge dataset.
- Updating the first relationship knowledge dataset may mean, for example, adding the second relationship knowledge data classified as a positive example to the first relationship knowledge dataset as new first relationship knowledge data.
- updating the first relationship knowledge dataset may mean, for example, replacing part or all of the first relationship knowledge dataset with the second relationship knowledge data classified as a positive example as new first relationship knowledge data.
- the updated first relationship knowledge dataset may be stored in the storage unit 120.
- the generation unit 12A may also output a score indicating the appropriateness of the second item "STEEP" (i.e., the second relationship knowledge data) generated for each context in response to the second prompt.
- the update unit 13A may update the first relationship knowledge dataset using the second relationship knowledge data classified as positive examples whose scores satisfy a predetermined condition (e.g., the score is equal to or greater than a threshold, the score is within a predetermined rank from the top, within a predetermined percentage, etc.).
- the update unit 13A may also update the first relationship knowledge dataset using the second relationship knowledge data classified as positive examples that is selected by the user.
- step S109 the third relationship knowledge dataset that is referenced the next time information processing method S1A is repeated is updated, improving the accuracy of the third prompt generated based on the third relationship knowledge dataset. As a result, the accuracy of determining negative examples for the second relationship knowledge data is improved. This makes it possible to accurately exclude negative examples from the second relationship knowledge dataset.
- step S111 the update unit 13A updates the relationship knowledge database 2A using the second relationship knowledge data classified as a positive example from the second relationship knowledge data set. For example, the update unit 13A adds the second relationship knowledge data classified as a positive example to the relationship knowledge database 2A as new "relationship knowledge data having a specific relationship.”
- the information processing device 1A repeats the information processing method S1A.
- the acquisition unit 11A acquires an updated first relationship knowledge dataset.
- the generation unit 12A generates a first prompt and a second prompt using the updated first relationship knowledge dataset.
- a new second relationship knowledge dataset is generated that references the updated first relationship knowledge dataset as an example.
- the judgment unit 16A generates a third prompt using the updated first relationship knowledge dataset and the updated third relationship knowledge dataset.
- the present exemplary embodiment employs a configuration in which a new second relationship knowledge data set is generated by referring to the updated first relationship knowledge data set as an example. Therefore, according to the present exemplary embodiment, since the first relationship knowledge data set, which has higher accuracy as having a specific relationship, can be referred to as an example, the relationship knowledge data having a specific relationship to be added to the relationship knowledge database 2A can be generated with high accuracy in accordance with the specified context.
- the relationship knowledge data stored in the relationship knowledge database 2A can be utilized for judgments, analyses, etc. in a specified context. In such cases, such judgments, analyses, etc. can be performed with high accuracy.
- the relationship knowledge data stored in the relationship knowledge database 2A can be utilized for management judgments, industry analysis, etc. in a specified industry. In such cases, changes/transformations in the industry can be accurately grasped, and future changes accompanying them can be accurately predicted.
- this exemplary embodiment employs a configuration in which the second relationship knowledge dataset, which satisfies a condition based on the score calculated by language model 3A, is used as second relationship knowledge data having a specific relationship to update the first relationship knowledge dataset. Therefore, according to this exemplary embodiment, the first relationship knowledge dataset can be updated using second relationship knowledge data that is highly likely to have a specific relationship based on the score, thereby improving the accuracy of the first relationship knowledge dataset that is referenced as an example having a specific relationship.
- this exemplary embodiment employs a configuration in which the second relationship knowledge data selected by the user from the second relationship knowledge data set is used as the second relationship knowledge data having a specific relationship to update the first relationship knowledge data set. Therefore, according to this exemplary embodiment, the first relationship knowledge data set can be updated using the second relationship knowledge data selected by the user as having a specific relationship, and therefore the accuracy of the first relationship knowledge data set referenced as an example having a specific relationship can be improved.
- this exemplary embodiment employs a configuration in which, by using the language model 3A, it is determined whether or not the second relationship knowledge data has a different relationship by referring to a third relationship knowledge dataset composed of third relationship knowledge data indicating a plurality of pieces of knowledge having a relationship different from the specific relationship as an example, and the second relationship knowledge data determined not to have a different relationship in the second relationship knowledge dataset is used as second relationship knowledge data having the specific relationship to update the first relationship knowledge dataset. Therefore, according to this exemplary embodiment, the same language model 3A is used to exclude negative examples from the second relationship knowledge dataset generated using the language model 3A, so accuracy can be ensured. Also, since it is not necessary to use a different model to exclude negative examples from the second relationship knowledge dataset generated using the language model 3A, negative examples can be more easily excluded.
- this exemplary embodiment employs a configuration in which the third relationship knowledge dataset is updated using the second relationship knowledge data determined to have a different relationship from the second relationship knowledge dataset. Therefore, according to this exemplary embodiment, the accuracy of the third relationship knowledge dataset having a relationship different from the specific relationship, which is referenced as a case to exclude negative examples from the second relationship knowledge dataset generated using the language model 3A, is improved, and as a result, it is possible to accurately extract relationship knowledge data having a specific relationship to be added to the relationship knowledge database 2A.
- the first relational knowledge data includes first antecedent data indicating knowledge of an antecedent, and first consequent data indicating knowledge of a consequent having a specific relationship to the antecedent knowledge
- the second relational knowledge data including the second antecedent data and the second consequent data is generated by using the language model 3A to generate second antecedent data corresponding to the context by referring to the first antecedent data as an example, and to generate second consequent data corresponding to the generated second antecedent data by referring to the first relational knowledge data as an example. Therefore, according to this exemplary embodiment, the second antecedent data corresponding to the specified context is first created, and then the second consequent data corresponding to the second antecedent data is generated, so that the second relational knowledge data corresponding to the specified context can be generated more accurately.
- the third relationship knowledge data set includes third relationship knowledge data having a first relationship different from the specific relationship, and third relationship knowledge data having a second relationship different from both the specific relationship and the first relationship.
- third relationship knowledge data having a second relationship different from both the specific relationship and the first relationship.
- a "causal relationship” is applied as the "specific relationship”
- a "synonymous relationship” may be applied as the "first relationship”
- an "implication relationship” may be applied as the second relationship.
- the first relationship and the second relationship are not limited to these examples.
- the judgment unit 16A judges whether each piece of second relationship knowledge data included in the second relationship knowledge data set has either the first relationship or the second relationship.
- a plurality of pieces of knowledge having the first relationship will also be referred to as first negative examples
- a plurality of pieces of knowledge having the second relationship will also be referred to as second negative examples.
- the samples included in the third prompt are modified as follows. Specifically, the determination unit 16A extracts some or all of the third relationship knowledge data having the first relationship from the third relationship knowledge dataset, and includes each of the extracted third relationship knowledge data as a sample of a first negative example in the third prompt. The determination unit 16A also extracts some or all of the third relationship knowledge data having the second relationship from the third relationship knowledge dataset, and includes each of the extracted third relationship knowledge data as a sample of a second negative example in the third prompt.
- the definition of the fourth item “Label” is transformed as follows.
- the definition of the fourth item “Label” is transformed into a natural language sentence explaining that "e” indicates the first negative example, “a” indicates the second negative example, and "x" indicates neither the first nor the second negative example.
- the determination unit 16A inputs the third prompt into the language model 3A to determine whether each piece of second relationship knowledge data included in the second relationship knowledge data set is a first negative example, a second negative example, or any other.
- the determination unit 16A may further determine whether the second relationship knowledge data determined by the language model 3A to be neither the first negative example nor the second negative example is a "positive example,” a "first negative example,” a "second negative example,” or "any other" based on the user's input.
- the update unit 13A updates the first relationship knowledge dataset using the second relationship knowledge data determined to be neither the first negative example nor the second negative example as the second relationship knowledge data having a specific relationship. Specifically, the update unit 13A updates the first relationship knowledge dataset using the second relationship knowledge data selected by the user as a "positive example” from the second relationship knowledge data determined to be neither the first negative example nor the second negative example. The update unit 13A also updates the third relationship knowledge dataset using the second relationship knowledge data selected by the user as a "first negative example" from the second relationship knowledge data determined to be neither the first negative example nor the second negative example. The update unit 13A also updates the third relationship knowledge dataset using the second relationship knowledge data selected by the user as a "second negative example" from the second relationship knowledge data determined to be neither the first negative example nor the second negative example.
- multiple types of negative examples are determined from the second relationship knowledge dataset to be excluded as they do not have a specific relationship, so negative examples that do not have a specific relationship can be excluded with greater accuracy. Note that, although an example in which there are two types of negative examples has been described here, there may be three or more types of negative examples.
- the determination unit 16A uses a first third prompt and a second third prompt.
- the first third prompt can be similarly explained by replacing "different relationship” with “first relationship” in the description of the third prompt in the exemplary embodiment 2.
- the second third prompt can be similarly explained by replacing "different relationship” with “second relationship” in the description of the third prompt in the exemplary embodiment.
- the determination unit 16A first determines whether each piece of second relationship knowledge data is a first negative example by inputting a first third prompt into the language model 3A. Furthermore, the determination unit 16A determines whether each piece of second relationship knowledge data determined not to be a first negative example is a second negative example by inputting a second third prompt into the language model 3A. This allows the determination unit 16A to determine whether each piece of second relationship knowledge data is a first negative example, a second negative example, or something else.
- multiple types of negative examples that are excluded from the second relationship knowledge dataset as not having a specific relationship are determined in stages, so that a binary determination is sufficient in one stage, and negative examples can be determined more accurately.
- the judgment unit 16A may judge whether each piece of second relationship knowledge data is a first negative example at one judgment stage, and judge whether it is either a second or third negative example at another judgment stage.
- the first relationship knowledge data, the second relationship knowledge data, and the third relationship knowledge data are each described as data indicating a relationship between two pieces of knowledge.
- these relationship knowledge data may be data indicating a relationship between three or more pieces of knowledge.
