Description

Case search apparatus, case search method, and computer-readable recording medium

The present invention relates to a case search apparatus, a case search method, and a computer-readable recording medium in which a program for realizing them is recorded for searching various cases.

Conventionally, the production of agricultural products has been performed based on the producer's experience and intuition backed by the experience, and it is difficult for an inexperienced producer to stably produce agricultural products. On the other hand, in Japan, experienced producers are aging, and it is required that producers with little experience can stably produce agricultural products in a short period of time.

Therefore, in recent years, in the agricultural field, attempts have been made to support producers by utilizing IT technology. One of the attempts is the introduction of a case search system that searches for similar cases. If such a case search system can be introduced, it is considered that it is possible to appropriately support producers with little experience.

As an existing case search system, for example, Patent Document 1 discloses a case search system for performing failure diagnosis of a vending machine. In the case search system disclosed in Patent Document 1, when a defect phenomenon is input, a corresponding case is output. Patent Document 2 discloses a case search system that supports a help desk operator. In the case search system disclosed in Patent Document 2, when a query such as a product name and a keyword is input, a combination of a question and an answer related to the query is selected from combinations of questions and answers registered in advance. Identified and output.

These existing case search systems combine a combination of a phenomenon occurring in a crop (for example, thin stems, thin leaves, etc.) and countermeasures taken against the phenomenon (fertilizer, watering, etc.). By using the stored database, it can be easily applied to the agricultural field. In this case, the producer can know the appropriate countermeasure by inputting the phenomenon occurring in the agricultural product in his / her field, so that it is considered that the producer can stably produce the agricultural product. .

1 and 2 of the present invention.

(Embodiment 1)
Hereinafter, a case search apparatus, a case search method, and a program according to Embodiment 1 of the present invention will be described with reference to FIGS.

[Device configuration]
First, the configuration of the case search apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a schematic configuration of a case search apparatus according to an embodiment of the present invention.

The case search apparatus 10 according to the first embodiment shown in FIG. 1 is an apparatus that performs a search with respect to the database 20 using an event of an agricultural product as a search query. The database 20 registers each of a plurality of events in association with a countermeasure for each event, a cause of each event, and a result of the countermeasure.

As illustrated in FIG. 1, the case search apparatus 10 includes a search query receiving unit 11, a search processing unit 12, a question presenting unit 13, and a cause estimating unit 14.

The search query receiving unit 11 receives a search query. The search processing unit 12 specifies an event that matches or is similar to the search query from the database 20 and extracts a cause associated with the specified event as a cause candidate.

When the question presenting unit 13 is associated with the same cause as the extracted cause candidate and there is an event that does not match or similar to the search query, the existing event occurs. Present a question that asks if The cause estimating unit 14 receives an answer to the presented question, and estimates the cause of the search query based on the extracted cause candidate when the received answer is affirmative.

As described above, in the first embodiment, the cause (for example, “temperature”, “fertilizer”, “water”, etc.) is narrowed down by using the event (for example, “no energy”) as a search query. Then, based on the cause candidates, a question is asked whether “other such an event (for example,“ the stem is thin ”,“ the leaves are deflated ”, etc.) has occurred”, and the cause is estimated based on the answer result. For this reason, according to this Embodiment 1, since a cause can be analyzed from the input event, as a result, it becomes possible to identify a more appropriate countermeasure for the agricultural product.

Subsequently, a specific configuration of the case search apparatus 10 according to the first embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a block diagram showing a specific configuration of the case search apparatus according to Embodiment 1 of the present invention. FIG. 3 is a diagram showing an example of information registered in the database used in Embodiment 1 of the present invention.

First, the first embodiment is applied to the agricultural field. As shown in FIG. 2, in the first embodiment, the case search device 10 is connected to a terminal device 30 of an agricultural producer through a network 40. In the first embodiment, the search query is input by the producer on the terminal device 30 and then transmitted from the terminal device 30. In the first embodiment, the search query receiving unit 11 receives a search query transmitted from the terminal device 30.

The database 20 is connected to the case search apparatus 10 in the first embodiment. As shown in FIG. 3, in the first embodiment, the database 20 displays the date and time, the action taken by the producer for the event, the cause of the event, and the target result for each event input by the producer. Registered in association.

For example, if the search query is “not good”, the search processing unit 12 obtains an event that matches the search query from the database 20, as shown in FIG. 3, ie, 12/1 to 12/3. Identify the event “I am not feeling well” registered in. As shown in FIG. 3, since the causes associated with the identified event are “temperature”, “fertilizer”, and “water”, the search processing unit 12 extracts these causes as candidate causes. To do.

In addition, as shown in FIG. 3, there are “stem is thin” and “leaf is deflated” as events associated with the same cause as the extracted cause candidates. Does not match or resembles. Therefore, in the first embodiment, the question presenting unit 13 creates a question for inquiring whether or not “the stem is thin” and “the leaf is deflated” have occurred as events.

In the first embodiment, the question presentation unit 13 transmits the created question to the terminal device 30 of the user who has input the search query via the network 40. Thereby, a question is displayed on the screen of the terminal device 30 of the producer who input the search query. And if a producer inputs a reply with respect to the displayed question and the terminal device 30 transmits a reply, the cause estimation part 14 will receive the transmitted reply.

For example, when the cause estimation unit 14 receives an answer that “the stem is thin” and “the leaf is deflated” as an event, the cause estimation unit 14 (“ Temperature ”,“ fertilizer ”,“ water ”) are estimated as the cause of the search query.

Further, as shown in FIG. 2, in the first embodiment, the case search apparatus 10 further includes a countermeasure determining unit 15. The handling determining unit 15 sets the handling associated with the estimated cause of the search query as the handling corresponding to the search query. In the above-described example, the countermeasure determining unit 15 sets “temperature reduction”, “fertilizer”, and “provide water” as countermeasures for the cause of the search query.

[Device operation]
Next, the operation of the case search apparatus 10 according to Embodiment 1 of the present invention will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the case search apparatus according to Embodiment 1 of the present invention. In the following description, FIG. 1 is taken into consideration as appropriate. Moreover, in this Embodiment 1, the case search method is implemented by operating the case search apparatus 10. Therefore, the description of the case search method in the first embodiment is replaced with the following description of the operation of the case search apparatus 10.

First, as shown in FIG. 4, the search query receiving unit 11 receives the search query transmitted from the terminal device 30 (step A1). In addition, the search query receiving unit 11 inputs the received search query to the search processing unit 12.

Next, the search processing unit 12 specifies an event that matches or is similar to the search query from the database 20 (step A2). Specifically, the search processing unit 12 performs similarity determination between the search query and each event registered in the database 20, and identifies an event having a certain degree of similarity with the search query. Similarity determination can be performed using existing technology.

Next, the search processing unit 12 determines whether or not an event that matches or is similar to the search query can be specified in Step A2 (Step A3). As a result of the determination in step A3, when the event cannot be specified, the process in the case search apparatus 10 ends. At this time, the case search apparatus 10 displays, for example, “There was no event related to the search query” on the screen of the terminal device 30.

On the other hand, if the event can be identified as a result of the determination in step A3, the search processing unit 12 extracts the cause associated with the event identified in step A2 from the causes registered in the database 20. Then, the extracted cause is set as a cause candidate (step A4).

Next, the question presentation unit 13 creates a question asking whether the event that can be identified in Step A2 has occurred, and sends the created question to the terminal device 30 that is the transmission source of the search query (Step A5). . By step A5, the terminal device 30 displays a question on the screen, and the question is presented to the producer. Thereby, the producer creates an answer to the question, and inputs the created answer to the terminal device 30. The terminal device 30 transmits the input answer to the case search device 10.

When an answer is transmitted from the terminal device 30, the cause estimating unit 14 determines whether or not the answer is affirmative with respect to the question (step A6). As a result of the determination in step A6, when the answer is not affirmative with respect to the question, the processing in the case search apparatus 10 ends. At that time, the case search apparatus 10 displays, for example, “There was no action corresponding to the search query” on the screen of the terminal device 30.

On the other hand, if the answer to the question is affirmative as a result of the determination in step A6, the cause estimating unit 14 estimates the cause candidate extracted in step A3 as the cause of the search query (step A7). Further, the cause estimating unit 14 inputs the estimated cause to the handling determining unit 15.

Next, the countermeasure determining unit 15 extracts a countermeasure associated with the estimated cause of the search query from the database 20, and determines the extracted countermeasure as a countermeasure corresponding to the search query (step A8). Further, the handling determining unit 15 transmits the determined handling to the terminal device 30 that is the transmission source of the search query. Thereby, the terminal device 30 displays the countermeasure on the screen, and the countermeasure is presented to the producer.

After the execution of step A8, the process in the case search apparatus 10 ends. Steps A1 to A8 are executed every time the producer inputs a search query.

[Effects of Embodiment 1]
As described above, according to the first embodiment, an appropriate cause corresponding to an event input as a search query is estimated, and a countermeasure for the estimated cause is determined. For this reason, since the producer can know appropriate measures, he can produce agricultural products stably. In addition to the agricultural field, the first embodiment is useful in various fields that require know-how such as plant system operation, steel furnace control, and maintenance of various machines.

[program]
The program in the first embodiment may be a program that causes a computer to execute steps A1 to A8 shown in FIG. By installing and executing this program on a computer, the case search apparatus 10 and the case search method in the present embodiment can be realized. In this case, a CPU (Central Processing Unit) of the computer functions as a search query receiving unit 11, a search processing unit 12, a question presenting unit 13, a cause estimating unit 14, and a handling determining unit 15, and performs processing.

Further, the program in the first embodiment may be executed by a computer system constructed by a plurality of computers. In this case, for example, each computer may function as any one of the search query receiving unit 11, the search processing unit 12, the question presenting unit 13, the cause estimating unit 14, and the countermeasure determining unit 15.

(Embodiment 2)
Next, a case search apparatus, a case search method, and a program according to Embodiment 2 of the present invention will be described with reference to FIGS.

FIG. 5 is a diagram showing an example of information registered in the database used in Embodiment 2 of the present invention. FIG. 6 is a flowchart showing the operation of the case search apparatus according to Embodiment 2 of the present invention.

First, in the second embodiment, the case search apparatus has the same configuration as the case search apparatus 10 in the first embodiment shown in FIG. Therefore, in the following description, reference is made to FIG. 2 as appropriate, and the reference numerals used in FIG. 2 are also used. However, the second embodiment is different from the first embodiment in the information registered in the database 20 and the processing in the question presenting unit 13 and the cause estimating unit 14. Hereinafter, the difference from Embodiment 1 will be mainly described.

As shown in FIG. 5, also in the second embodiment, the database 20 stores the date and time, the action taken by the producer for the event, the cause of the event, and the target for each event, as in the first embodiment. The result of the association is registered. However, in the second embodiment, the database 20 further registers numerical data and setting conditions (hereinafter referred to as “alert conditions”) for outputting alerts. In the database 20, the numerical data and the alert condition are associated with causes associated with each other by respective numbers.

Suppose that the cause related to the numerical data is extracted as a cause candidate by the search processing unit 12. In this case, the question presenting unit 13 presents numerical data related to the extracted cause candidates. Specifically, the question presenting unit 13 transmits to the terminal device 30 a question for inquiring whether or not the event identified from the search query is related to the numerical data.

Further, after this, the cause estimating unit 14 relates to the numerical data when the accepted answer recognizes that the numerical data is related to the identified event, that is, when the question is affirmed. Estimate the cause of a search query based on possible causes. Specifically, for example, if the cause estimating unit 14 obtains an answer indicating that the lack of energy in the crop is related to the fact that the precipitation is low, the “water Is estimated as the cause.

Further, it is assumed that causes related to numerical data and alert conditions have been extracted as cause candidates by the search processing unit 12. In this case, the question presentation unit 13 presents numerical data and alert conditions related to the cause candidate. Specifically, the question presentation unit 13 transmits a question for inquiring whether or not this numerical data satisfies the alert condition to the terminal device 30.

Further, after this, the cause estimating unit 14 relates to the numerical data and the alert condition when the accepted answer recognizes that the numerical data satisfies the alert condition, that is, when the question is affirmed. Estimate the cause of a search query based on possible causes. Specifically, for example, if the cause estimating unit 14 obtains an answer that the change in the temperature satisfies the alert condition, the cause estimating unit 14 estimates the “temperature” associated with the temperature data and the alert condition as a cause. .

Next, the operation of the case search apparatus 10 according to Embodiment 2 of the present invention will be described with reference to FIG. Also in the second embodiment, the case search method is implemented by operating the case search apparatus 10. Therefore, the description of the case search method in the second embodiment is also replaced with the operation description of the case search apparatus 10 below.

First, as shown in FIG. 6, the search query receiving unit 11 receives the search query transmitted from the terminal device 30 (step B1). Step B1 is the same as step A1 shown in FIG.

Next, the search processing unit 12 specifies an event that matches or is similar to the search query from the database 20 (step B2). Step B2 is the same as step A2 shown in FIG.

Next, the search processing unit 12 determines whether or not an event that matches or is similar to the search query can be specified in Step B2 (Step B3). Step B3 is the same as step A3 shown in FIG. As a result of the determination in step B3, when the event cannot be specified, the process in the case search apparatus 10 ends. At this time, the case search apparatus 10 displays, for example, “There was no event related to the search query” on the screen of the terminal device 30.

On the other hand, if the event can be identified as a result of the determination in step B3, the search processing unit 12 extracts the cause associated with the event identified in step B2 from the causes registered in the database 20. Then, the extracted cause is set as a cause candidate (step B4). Step B4 is the same as step A4 shown in FIG.

Next, the question presentation unit 13 selects one of the extracted cause candidates (Step B5), accesses the database 20, and determines whether the selected cause candidate is related to numerical data (Step S5). B6).

As a result of the determination in step B6, when the selected cause candidate is not related to the numerical data, the question presenting unit 13 creates and creates a question asking whether the event identified in step B2 has occurred. The question is transmitted to the terminal device 30 that is the transmission source of the search query (step B7). Step B7 is the same as step A5 shown in FIG.

On the other hand, if the selected cause candidate is related to the numerical data as a result of the determination in step B6, the question presenting unit 13 further determines whether the selected cause candidate is related to the alert condition (step) B8).

As a result of the determination in step B8, when the selected cause candidate is not related to the alert condition, the question presenting unit 13 presents numerical data related to the extracted cause candidate (step B9). Specifically, the question presenting unit 13 transmits to the terminal device 30 a question for inquiring whether or not the event identified from the search query is related to the numerical data.

On the other hand, as a result of the determination in step B8, if the selected cause candidate is related to the alert condition, the question presenting unit 13 presents numerical data and an alarm condition related to the extracted cause candidate (step) B10). Specifically, the question presentation unit 13 transmits a question for inquiring whether or not this numerical data satisfies the alert condition to the terminal device 30.

After execution of Step B7, Step B9, or Step B10, when an answer is transmitted from the terminal device 30, the cause estimating unit 14 determines whether the answer is affirmative with respect to the question (Step B11). If the result of determination in step B11 is that the answer is not positive for the question, step B13 is executed.

On the other hand, if the answer to the question is affirmative as a result of the determination in step B11, the cause estimating unit 14 estimates the cause candidate selected in step B5 as one of the causes of the search query (step B12). ).

Next, the cause estimating unit 14 determines whether or not the processing from Step B6 to B12 has been completed for all the cause candidates extracted in Step B4 (Step B13). As a result of the determination in step B13, when the processing from step B6 to B12 is not completed for all cause candidates, the cause estimating unit 14 causes the question presenting unit 13 to execute step B5 again.

On the other hand, as a result of the determination in step B13, when the processes from step B6 to B12 have been completed for all the cause candidates, the cause estimating unit 14 inputs all the estimated causes to the handling determining unit 15. Thereby, the countermeasure determining unit 15 extracts the countermeasure associated with the estimated cause of the search query from the database 20, and determines the extracted countermeasure as a countermeasure corresponding to the search query (step B14). Step B14 is the same as step A8 shown in FIG.

After the execution of Step B14, the process in the case search apparatus 10 ends. Steps B1 to B14 are executed every time the producer inputs a search query.

As described above, according to the second embodiment, when numerical data and alert conditions are registered in the database, the cause can be specified using these data. According to the second embodiment, the cause can be identified more appropriately. As in the first embodiment, the second embodiment is useful not only in the agricultural field but also in various fields that require know-how such as plant system operation, steel furnace control, and maintenance of various machines.
