DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present disclosure will be described. Note that the present disclosure is not limited to the following embodiment. Note that in the following drawings, the same parts are assigned the same reference numerals. Furthermore, the descriptions of the embodiments can be used interchangeably unless otherwise specified. Furthermore, the configurations of the embodiments can be combined unless otherwise specified. Furthermore, in each procedure described below in the program of the present disclosure, for example, "procedure" can be read as "processing."

[0013] [Embodiment 1] An ontology evaluation program, an ontology evaluation device, and an ontology evaluation method according to the present disclosure will be described.

[0014] The ontology evaluation program of the present disclosure is a program for causing a computer to execute an acquisition procedure and an evaluation procedure. The ontology evaluation program of the present disclosure can also be said to be a program for causing a computer to function as the acquisition procedure and the evaluation procedure. Furthermore, the ontology evaluation program of the present disclosure can also be said to be a program for causing a computer to execute, for example, each step of an ontology evaluation method described below.

[0015] Next, an example of the ontology evaluation device of the present disclosure will be described with reference to FIGS.

[0016] 1 is a block diagram showing an example of the configuration of an ontology evaluation device 10 (the present device 10) according to the present disclosure. As shown in FIG. 1, the present device 10 includes an acquisition unit 11 and an evaluation unit 12.

[0017] The device 10 may be, for example, a single device including the above-described units, or a device in which the units can be connected via a communication network. The device 10 can also be connected to an external device (described later) via the communication network. The communication network is not particularly limited and any known network can be used, for example, a wired or wireless network. Examples of the communication network include the Internet, the World Wide Web (WWW), a telephone line, a Local Area Network (LAN), a Storage Area Network (SAN), a Delay Tolerant Networking (DTN), a Low Power Wide Area Network (LPWA), and a Local 5G (L5G). Examples of wireless communication include Wi-Fi (registered trademark), Bluetooth (registered trademark), Local 5G, and LPWA. Examples of the wireless communication include direct communication between devices (Ad Hoc communication), infrastructure communication, and indirect communication via an access point. The device 10 may be incorporated into a server as a system. Furthermore, the present device 10 may be, for example, a personal computer (PC, for example, desktop or notebook type) on which the program of the present disclosure is installed, a smartphone, a tablet terminal, digital signage, etc. The present device 10 may be in the form of cloud computing or edge computing, for example, in which at least one of the above-mentioned units is located on a server and the other units are located on a terminal.

[0018] 2 shows a block diagram of the hardware configuration of the device 10. The device 10 includes, for example, a central processing unit (CPU, GPU, etc.) 101, a memory 102, a bus 103, a storage device 104, an input device 105, an output device 106, and a communication device 107. The components of the device 10 are connected to each other via the bus 103 and their respective interfaces (I / F).

[0019] The central processing unit 101 operates in cooperation with other components via a controller (such as a system controller or an I / O controller) and is responsible for overall control of the device 10. In the device 10, the central processing unit 101 executes, for example, the program of the present disclosure and other programs, and also reads and writes various types of information. Specifically, for example, the central processing unit 101 functions as an acquisition unit 11 and an evaluation unit 12. The central processing unit 101 may include, as a computing device, a CPU, a GPU (Graphics Processing Unit), an APU (Accelerated Processing Unit), or a combination of these.

[0020] The bus 103 can also be connected to, for example, an external device. Examples of the external device include an external storage device such as an external database, a printer, an external input device, an external display device, an external imaging device, etc. The device 10 can be connected to an external network (the communication line network) by, for example, a communication device 107 connected to the bus 103, and can also be connected to other devices via the external network.

[0021] The memory 102 may be, for example, a main memory (primary storage device). When the central processing unit 101 performs processing, the memory 102 reads various operating programs, such as the program of the present disclosure, stored in the storage device 104 (described later), and the central processing unit 101 receives data from the memory 102 and executes the programs. The main memory may be, for example, a RAM (random access memory). The memory 102 may also be, for example, a ROM (read only memory).

[0022] The storage device 104 is also referred to as a so-called auxiliary storage device, for example, in contrast to the main memory (primary storage device). As described above, the storage device 104 stores an operating program including the program of the present disclosure. The storage device 104 may be, for example, a combination of a recording medium and a drive that reads and writes from and to the recording medium. The recording medium is not particularly limited and may be, for example, an internal or external type, such as a hard disk (HD), CD-ROM, CD-R, CD-RW, MO, DVD, flash memory, or memory card. The storage device 104 may be, for example, a hard disk drive (HDD) or a solid state drive (SSD) in which the recording medium and drive are integrated.

[0023] In the present device 10, the memory 102 and the storage device 104 can also store various information such as log information, information acquired from an external database (not shown) or an external device, information generated by the present device 10, and information used when the present device 10 executes processing. In this case, the memory 102 and the storage device 104 may store, for example, ontologies, sentences, relationship evaluation results, etc., which will be described later. Note that at least a portion of the information may be stored, for example, in an external server other than the memory 102 and the storage device 104, or may be stored in a distributed manner across multiple terminals using blockchain technology or the like.

[0024] The device 10 further includes, for example, an input device 105 and an output device 106. Examples of the input device 105 include pointing devices such as a touch panel, track pad, and mouse; a keyboard; imaging means such as a camera and scanner; card readers such as an IC card reader and a magnetic card reader; and audio input means such as a microphone. Examples of the output device 106 include display devices such as an LED display and a liquid crystal display; audio output devices such as a speaker; a printer; and the like. In the present disclosure, the input device 105 and the output device 106 are configured separately, but the input device 105 and the output device 106 may also be configured as an integrated device, such as a touch panel display.

[0025] First, an example of the processing of the ontology evaluation program of the present disclosure will be specifically described with reference to Fig. 3. Fig. 3 is a flowchart showing an example of each procedure of the ontology evaluation program of the present disclosure.

[0026] The acquisition unit 11 acquires two or more ontologies (S11, acquisition procedure). The acquisition unit 11 may acquire the two or more ontologies by generating an ontology from two or more sentences, for example. The description format of the ontology is not particularly limited, and the two or more ontologies may be written in the same format or in different formats, but it is preferable that they are written in the same format. The sentences are not particularly limited, and examples include novels and sentences describing ideal futures. Note that when generating an ontology from the two or more sentences, the ontology may be generated by, for example, a generation unit (generation procedure) included in the device 10, or the ontology may be generated by a device other than the device 10. The generation of the ontology may be performed, for example, by a conventionally known method.

[0027] Next, the evaluation unit 12 compares the properties of the ontologies to evaluate the ontologies (S12, evaluation procedure). For example, the evaluation unit 12 compares the properties of the ontologies and further evaluates the relationships between at least two or more objects selected from individuals, groups, and objects, which are the sources of the text expressed as the ontologies. For example, the evaluation unit 12 evaluates provocativeness or novelty, matching between individuals, or matching between individuals and groups, based on the evaluation results of the relationships. Specifically, if the sources are all individuals, the evaluation unit 12 evaluates the matching between individuals based on the evaluation results of the relationships between individuals. The evaluation of the matching between individuals is, for example, an evaluation of matching between individuals based on commonalities of ideas and inclinations, such as an evaluation of matching between individuals with high expandability of ideas, matching between individuals with high similarity in ideal future visions, and matching between individuals with similar ideal visions of future lives. The matching between individuals can be, for example, one-to-one matching between individuals, partner matching, or group matching (group creation) between multiple individuals. When the source is an individual and a group, the evaluation unit 12 evaluates the matching between the individual and the group based on the evaluation result of the relationship between the individual and the group. The group is not particularly limited, and examples thereof include any group such as a company, department, team, class, club, or community. When the source is an individual and a company, the evaluation of the matching between the individual and the group may include, for example, an evaluation of the career match between the individual and the company based on future work styles. When the source is all objects, the evaluation unit 12 evaluates the provocation or novelty based on the evaluation result of the relationship between the objects. The objects are not particularly limited, and examples thereof include novels and writings describing ideal futures. When the source is a novel, the evaluation of the provocation or novelty may include, for example, an evaluation of the provocation or novelty as a novel. The evaluation unit 12 evaluates the ontology, for example, by comparing the properties of the components of the ontology. The evaluation unit 12 evaluates the ontology by comparing the properties of the nodes and links that make up the ontology. The properties include, for example, similarity.The evaluation unit 12 may evaluate the ontology by, for example, scoring the properties of the nodes and the links.

[0028] Next, the ontology evaluation method of the present disclosure will be described.

[0029] The ontology evaluation method of the present disclosure can incorporate the descriptions of the ontology evaluation program and ontology evaluation device of the present disclosure. The ontology evaluation method of the present disclosure is a method implemented by, for example, replacing the "procedures" in the program of the present disclosure with "steps." Specifically, the ontology evaluation method of the present disclosure includes an acquisition step and an evaluation step. The ontology evaluation method of the present disclosure can be implemented using, for example, the device 10 of FIG. 1. Note that the ontology evaluation method of the present disclosure is not limited to use with the device 10 of FIG. 1.

[0030] [Embodiment 2] An example of an ontology evaluation method using the ontology evaluation device of the present disclosure will be described with specific examples using Figures 4 and 5. Note that, although an example using the device 10 is shown in the present disclosure, the present disclosure is not limited to this. Furthermore, the ontology expression methods described in Figures 4 and 5 are merely examples and are not limited to these.

[0031] First, a method for evaluating an ontology will be described using FIG. 4. The device 10 acquires two or more ontologies. In FIG. 4, the definitions of "human" in novels written by Person A and Person B are expressed as ontologies. Next, the properties of the acquired ontologies are compared to evaluate the ontologies. In FIG. 4, the ontologies are evaluated as scores based on the number of links (has a, is a) connecting nodes (human, powered arm, mammal, BMI (Body Mass Index), brain) in the acquired ontologies, and matching between individuals is evaluated based on the magnitude of the score. Specifically, in the two ontologies shown in FIG. 4, Person A's definition of "human" has one "is a" and one "has a," while Person B's definition of "human" has zero "is a" and two "has a." The sum of the absolute values ​​of the differences between these links is "2," resulting in a score of "2." For example, if the definition of "human" in a written novel is expressed as an ontology and scored as described above, pairs of individuals with high scores can be presented as evaluation results, with "combinations of highly scalable people or worldviews." Furthermore, pairs of individuals with low scores can be presented as evaluation results, with "combinations of highly similar people or worldviews." Based on the presented evaluations, matching between individuals can be evaluated, which can be useful, for example, for creating teams to create new businesses.

[0032] Next, another ontology evaluation method will be described using FIG. 5. As in FIG. 4, the device 10 acquires two or more ontologies. In FIG. 5, the definitions of "human" in novels C and D are expressed as ontologies. Next, the acquired ontologies are compared to evaluate the ontologies. In FIG. 5, the ontologies are evaluated as scores based on the number of combinations of nodes (human, powered arm, mammal, tail) and links (has a, is a) connecting them in the acquired ontologies. The magnitude of the score evaluates the "novelty," "speculativeness," "provocativeness," etc. of the novel. Specifically, since there is only one different node-link combination in the two ontologies shown in FIG. 5 (human has a powered arm and human has a tail), the score is "1." The magnitude of this score can be used to evaluate the "novelty," "speculativeness," "provocativeness," etc. of the novel.

[0033] [Embodiment 3] The program of the present disclosure may be recorded on, for example, a computer-readable recording medium. The recording medium may be, for example, a non-transitory computer-readable storage medium. The recording medium is not particularly limited, and examples thereof include random access memory (RAM), read-only memory (ROM), hard disk (HD), flash memory (e.g., USB flash memory, SD / SDHC card, etc.), optical disk (e.g., CD-R / CD-RW, DVD-R / DVD-RW, BD-R / BD-RE, etc.), magneto-optical disk (MO), floppy disk (FD), etc. Furthermore, the program of the present disclosure (also referred to as, for example, a programming product or program product) may be distributed from, for example, an external computer. The "distribution" may be, for example, distribution via a communication network or via a device connected via a wired connection. The program of the present disclosure may be installed and executed on the device to which it is distributed, or may be executed without being installed.

[0034] Although the present disclosure has been described above with reference to the embodiments, the present disclosure is not limited to the above embodiments. The configuration and conditions of the present disclosure may be modified in various ways that are understandable to those skilled in the art within the scope of the present disclosure.
