Determination apparatus, determination method, and non-transitory computer readable storage medium

1. A determination device comprising:

a processor configured to:

acquire a search query(ies) input by a plurality of input customers who have input a reference query;

categorize the search queries input in a predetermined period among the search queries into a plurality of categories;

determine whether a categorization result of the categorization satisfies a predetermined determination condition or not;

extract a search query categorized into the category that satisfies a predetermined categorization condition among the plurality of categories if it is determined that the categorization result satisfies the predetermined determination condition; and

provide a list of the extracted search queries.

2. The determination device according to claim 1 , wherein the processor is further configured to:

determine whether a number of the categories into which the search queries have been categorized satisfies a predetermined condition or not.

3. The determination device according to claim 2 , wherein the processor is further configured to:

determine whether the number of the categories into which the search query of predetermined percentage or higher among the search queries are categorized is equal to or less than a threshold value.

4. The determination device according to claim 2 , wherein the processor is further configured to:

specify the category into which the search query of predetermined percentage or higher among the search queries is categorized and

determine whether the number of the customer who have input the search query categorized into the specified category is equal to or higher than a predetermined threshold value.

5. The determination device according to claim 1 , wherein the processor is further configured to:

acquire the search query input in a period before reference time and date, at which the input customer has input a reference query, by predetermined time and date as the predetermined period.

6. The determination device according to claim 5 , wherein the processor is further configured to:

acquire the search query(ies) input in a mutually different plurality of periods based on the reference time and date;

categorize the search queries into the plurality of categories for each of the period; and

determine whether the categorization result satisfies the predetermined determination condition or not for each period.

7. The determination device according to claim 1 , wherein the processor is further configured to:

determine whether a high-level category into which the category into which the search query is categorized satisfies a predetermined condition or not.

8. The determination device according to claim 1 , wherein the processor is further configured to:

output information that the reference query is appropriate if it is determined that the categorization result satisfies the predetermined determination condition.

9. The determination device according to claim 1 , wherein the processor is further configured to:

output information that the plurality of categories into which the search queries are categorized are appropriate if it is determined that the categorization result satisfies the predetermined determination condition.

10. The determination device according to claim 1 , wherein the processor is further configured to:

specify the category into which the search query of predetermined percentage or higher is categorized among the search queries and extracts the search query categorized into the specified category.

11. The determination device according to claim 1 , wherein the processor is further configured to:

extract the search query having high relativity with the reference query among the search queries.

12. The determination device according to claim 1 , wherein the processor is further configured to:

specify, as a keyword used in targeting based on a first search query, a second search query input before the first search query is input and related to the first search query among the search queries.

13. A determination method executed by a determination device, the method including:

acquiring a search query(ies) input by a plurality of input customers who have input a reference query;

categorizing the search queries input in a predetermined period among the search queries into a plurality of categories;

determining whether a categorization result of the categorization satisfies a predetermined determination condition or not;

extracting a search query categorized into the category that satisfies a predetermined categorization condition among the plurality of categories if it is determined that the categorization result satisfies the predetermined determination condition; and

providing a list of the extracted search queries.

14. A non-transitory computer readable storage medium having a determination program thereon, the determination program causes a computer to perform:

acquiring a search query(ies) input by a plurality of input customers who have input a reference query;

categorizing the search queries input in a predetermined period among the search queries into a plurality of categories;

determining whether a categorization result of the categorization satisfies a predetermined determination condition or not;

extracting a search query categorized into the category that satisfies a predetermined categorization condition among the plurality of categories if it is determined that the categorization result satisfies the predetermined determination condition; and

providing a list of the extracted search queries.
