Description

The present invention relates to a display mode change device that changes the display mode of characters.

In order to improve and establish brand power, active use of corporate logos is desirable. In response to this, Patent Document 1 discloses a computer system that converts received text into a corporate logo, etc.

Patent No. 5002017

However, it is not advisable to convert any text into a logo and display it on the site. For example, if a logo is included in text that is intended to be defamatory, there is a risk that a negative image of the logo will take root if the text is widely spread. This could result in the brand power of the logo being damaged.

The present invention has been made in consideration of these circumstances. Its purpose is to provide a display mode change device or the like that changes the display mode of a named entity, such as a company name or brand name, again when the content of a sentence that contains the named entity, whose display mode has been changed from a character string to another mode such as a logo or a specified font, does not satisfy a specified standard.

The display mode change device according to the present invention includes a change unit that changes the display mode of a named entity in an input character string to another mode, and a determination unit that determines whether or not character data associated with the named entity satisfies a predetermined criterion for avoiding a negative impression, and when the determination unit determines that the predetermined criterion is not satisfied, the change unit changes the display mode of the named entity back to the original display mode or to a mode associated with the changed other mode.

In the present invention, when a sentence contains a named entity whose display mode has been changed to another mode, and the content does not satisfy a predetermined standard, the display mode of the named entity is changed again, thereby making it possible to prevent damage to the brand power of the other mode.

The following describes an embodiment of this disclosure with reference to the drawings.

First embodiment
1 is an explanatory diagram showing the configuration of an SMS system. The SMS (Short Message Service) system 100 includes a plurality of communication devices 1 and a telephone communication network N that mediates communication between the communication devices 1. The communication devices (display mode change devices) 1 are composed of a smartphone, a tablet computer, a notebook computer, or the like.

Figure 2 is a block diagram showing an example of the configuration of a communication device. The communication device 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a large-capacity storage unit 14, a touch panel display 15, and a communication unit 16. Each component is connected by a bus B.

The CPU 11 performs various information processing by appropriately executing the control program 1P stored in the ROM 12. The control program 1P includes a function for using SMS. The control program 1P also incorporates the display mode change program of this disclosure or the functions of that program. The RAM 13 is, for example, an SRAM (Static RAM), a DRAM (Dynamic RAM), or a flash memory. The RAM 13 temporarily stores data generated when the CPU 11 executes a program.

The large-capacity storage unit 14 is, for example, a hard disk or a solid state drive (SSD). The large-capacity storage unit 14 stores various databases (DB: Data Base). The large-capacity storage unit 14 stores a logo image DB 141, a forbidden word DB 142, and an emotional expression DB 143. The control program 1P may also be stored in the large-capacity storage unit 14. All or part of the logo image DB 141, the forbidden word DB 142, and the emotional expression DB 143 may be stored outside the communication device 1. For example, they may be stored in a database server or cloud storage.

The touch panel display 15 is a combination of an image display device such as a liquid crystal panel and a position input device such as a touch pad. Instead of the touch panel display 15, a display unit such as a liquid crystal panel and an input unit such as a keyboard and a track pad may be provided.

The communication unit 16 is an interface for connecting to the telephone communication network N by wired communication or wireless communication. The communication unit 16 transmits and receives short messages to and from other communication devices via the telephone communication network N. The CPU 11 may also download the control program 1P from an external device via the telephone communication network N through the communication unit 16 and store it in the mass storage unit 14.

The DB used in the SMS system 100 will be described. FIG. 3 is an explanatory diagram showing an example of the logo image DB. The logo image DB 141 stores logo images and the like. The logo image DB 141 includes a word string, a logo string, a markup string, and a re-change string. The word string stores words corresponding to logos. The words stored in the word string are words (character strings) corresponding to named entities. Here, the words corresponding to named entities are company names, abbreviations of company names, or nicknames of companies, or product names or service names, etc. The logo string stores logo images (conversion candidates). Instead of storing logo images in the logo string, identification information for acquiring logo images, such as image file names, may be stored. Hereinafter, the logo image is also simply referred to as a logo. The markup string stores tags corresponding to logos. The tags correspond one-to-one to logo images. In the SMS system 100, when each communication device 1 stores a logo image, the communication devices 1 do not transmit and receive logo images to each other, but embed tags indicating the logo image in the transmitted message. When the communication device 1 receives the message and displays the message, it converts the tag into a logo image and displays it. When sending a logo image, the sending communication device 1 sends text data with the tag embedded as a message. It also sends an image file with the tag attached as an attribute. When the receiving communication device 1 displays the received text data, if a tag is included, it replaces it with an image corresponding to the tag and displays it. The re-change column stores the text (already stored form) to be replaced when changing the logo image back to text.

Figure 4 is an explanatory diagram showing an example of a forbidden word DB. The forbidden word DB (word storage unit) 142 stores words that, if the word and logo image are included in the message, will prevent the message from being sent. The forbidden word DB 142 includes strings of forbidden words. The forbidden word strings store forbidden words. For example, forbidden words are words that show negative emotions such as resentment, jealousy, rancor, hatred, desperation, and destructive impulses, and words used in expressions intended to slander.

The following describes the functions realized by the CPU 11 of the communication device 1 executing the control program 1P. FIG. 5 is a block diagram showing the functional configuration of the communication device. FIGS. 6 to 8 are explanatory diagrams showing example screens. When the CPU 11 of the communication device 1 executes the control program 1P stored in the ROM 12, it realizes the functions of the first reception unit 101, the extraction unit 102, the matching unit 103, the acquisition unit 104, the second reception unit 105, the change unit 106, the transmission reception unit 107, and the determination unit 108. Note that in this embodiment, these functions are realized by the CPU 11 executing the control program 1P, but some of these functions may be realized by dedicated hardware circuits.

In this embodiment, the CPU 11 of the communication device 1 executes the control program 1P. When the CPU 11 receives an instruction to create a message to be sent from the user via the touch panel display 15, the CPU 11 displays the creation screen shown in FIG. 6A on the touch panel display 15. The screen shown in FIG. 6A displays a software keyboard for inputting Japanese. FIG. 6A shows a scene in which a message (character data) is being input using kana-kanji conversion. Conversion candidates are displayed for the hiragana entered by the user. The user is entering "ima makku". Then, "ima mac" (mac is a registered trademark) is selected from the conversion candidates. FIG. 6B shows the state after the user has completed the selection of candidates and the conversion has been confirmed. When the conversion has been confirmed, the first reception unit 101 accepts the input text. The extraction unit 102 analyzes the text accepted by the first reception unit 101 and extracts words. The collation unit 103 compares the words (character strings) extracted by the extraction unit 102 with the logo image DB 141 and determines whether they are registered. The acquisition unit 104 acquires a logo image for a word (named entity) registered in the logo image DB 141. The acquisition unit 104 displays the logo image as a conversion candidate on the touch panel display 15. FIG. 6C shows a screen displaying conversion candidates for the word "Mac." The candidates are "McDonald's (registered trademark)," a mark with two arches joined together that resembles an M (this mark is a registered trademark), and a mark of a bitten apple (this mark is a registered trademark). The user selects one of the conversion candidates using the touch panel display 15 in the same way as in the kana-kanji conversion. The second reception unit 105 receives the selection result (selection information). The change unit 106 changes the word to a logo image in accordance with the selection result. That is, the change unit 106 changes the display mode of the named entity to a logo.

The screen shown in FIG. 7A shows an example of the screen after the word has been changed to a logo image. When the user selects the send button 71 on the screen shown in FIG. 7A to give a send instruction (output instruction), the transmission reception unit 107 accepts the transmission message (the named entity and the character data associated with the named entity). The determination unit 108 determines whether the content of the transmission message is suitable for sending a logo image. Here, the unacceptable word DB 142 is checked to see whether the transmission message contains words that cannot be combined with a logo image, unacceptable words. If the determination unit 108 determines that the transmission message does not contain unacceptable words, the transmission reception unit 107 transmits the transmission message including the logo image via the communication unit 16. FIG. 7B shows an example of the screen after the transmission message including the logo image has been sent.

If the determination unit 108 determines that the message to be sent contains a forbidden word, the change unit 106 changes the logo image back to text. The text to be changed back to is obtained from the re-change column of the logo image DB 141. The transmission acceptance unit 107 transmits the message to be sent in which the logo image has been changed back to text via the communication unit 16. Figure 8A shows an example in which a message containing the forbidden word "extremely angry" has been input. Following the message input in Figure 7A, "But, extremely angry..." has been input. In Figure 8A, when the send button 71 is pressed, the logo image is changed back to "McDonald's (registered trademark)" and then sent. Figure 8B shows the message that was actually sent.

Next, the flow of processing in the communication device 1 will be described using a flowchart. FIG. 9 is a flowchart showing an example of the procedure of the transmission process. When the CPU 11 of the communication device 1 receives an instruction to create a message to be sent from a user, the CPU 11 generates a creation screen for creating a message to be sent and displays it on the touch panel display 15 (step S1). An example of the creation screen is shown in FIG. 6 and the like. The user inputs a message on the creation screen. The CPU 11 determines whether or not text has been accepted (step S2). For example, the CPU 11 accepts text when the content entered by kana-kanji conversion on the creation screen is confirmed. When the CPU 11 determines that text has been accepted (YES in step S2), it extracts words contained in the text and compares the extracted words with words stored in the logo image DB 141 (step S3). The CPU 11 determines whether or not there is a word corresponding to the logo (step S4). When the CPU 11 determines that there is a word corresponding to the logo (YES in step S4), it acquires a logo image from the logo image DB 141 (step S5). The CPU 11 displays the acquired logo images as candidates on the touch panel display 15 (step S6). The CPU 11 accepts the selection result (step S7). Based on the selection result, the CPU 11 changes the display of the word to the logo image (step S8). The CPU 11 returns the process to step S4. In step S4, the CPU 11 determines whether there are any other words that have not been changed. If the CPU 11 determines that there are no unprocessed words that correspond to the logo (NO in step S4), the CPU 11 returns the process to step S2.

When it is determined that no text has been received (NO in step S2), such as when no text has been input or when the kana-kanji conversion has not been confirmed, the CPU 11 determines whether or not transmission has been instructed (step S9). When it is determined that no transmission has been instructed (NO in step S9), the CPU 11 returns the process to step S2. When it is determined that transmission has been instructed (YES in step S9), the CPU 11 makes a determination (step S10). For example, it determines whether or not the received text contains an incompatible word stored in the incompatible word DB 142. The CPU 11 determines whether or not transmission is possible (step S11). When the text does not contain an incompatible word, the CPU 11 determines that transmission is possible. When the text contains an incompatible word, the CPU 11 determines that transmission is impossible. When it is determined that transmission is impossible (NO in step S11), the CPU 11 re-changes the incompatible word (step S12). That is, the logo image is changed to the corresponding re-changed text. If the CPU 11 determines that transmission is possible (YES in step S11), the process proceeds to step S13. The CPU 11 transmits the text via the communication unit 16. Determining whether transmission is possible or not based on whether or not the text contains prohibited words is an example of a predetermined criterion in the present disclosure.

As described above, in this embodiment, if the message text including the logo image contains a word (unacceptable word) that may weaken the brand power, the logo image is changed to text. This makes it possible to avoid the possibility of a negative image of the logo becoming established. As a result, it is possible to prevent the brand power of the logo from being damaged. Although the logo image is used to display the logo, a font corresponding to the logo may be created. A font dictionary that stores the characters that make up the logo as fonts is stored in the mass storage unit 14. Instead of the logo image DB 141, a table that associates named entities with font names is prepared. When changing the display mode, first, the font name is obtained from the named entity. The display font of each character that makes up the named entity is set to the font of the obtained font name. The display mode of each character becomes a mode (other mode) corresponding to the logo stored in the font dictionary, and the logo is displayed as a whole.

When a user is inputting hiragana when creating a message, the predictive conversion of an IME (input method editor) may be used. In the example of FIG. 6, when the user inputs "ima mama", the IME may display candidates such as "ima mac" and "ima mac". When the user selects "ima mac", the extraction unit 102 extracts "ima" and "mac". The collation unit 103 compares each of "ima" and "mac" with the logo image DB 141. When "ma" is input, the IME displays the candidate "mac" and when the user selects "mac", the extraction unit 102 passes "mac" as it is to the collation unit 103. The collation unit 103 may display a logo corresponding to "mac" as a conversion candidate. Furthermore, the IME may cooperate with the collation unit 103 and the acquisition unit 104. For example, when the user types "ima mama," a candidate such as "ima McDonald's" is displayed. In other words, instead of showing the character string "makku" as a candidate for "ma," the system can predict that "ma" means "makku," replace "ma" with the logo that corresponds to "makku," and display it as a conversion candidate.

Variation 1
A modified example of the first embodiment will be described. In the above, when a logo image is changed again to a word, the word stored in the changed column of the logo image DB 141 is used. However, when a plurality of words correspond to one logo image, the word may be different from the word input by the user, causing the user to feel uncomfortable. Therefore, when a word is changed to a logo image (step S8), the word before the change is stored in a temporary storage area provided in the RAM 13 or the large-capacity storage unit 14. Then, when the word is changed again (step S12), the word stored in the temporary storage area (stored state) is used. FIG. 10 is an explanatory diagram showing an example of a screen. FIG. 10 shows a screen when the logo image of the message shown in FIG. 8A is returned to text. The logo image of two combined arches is changed again to the word "Mac" (the inputted named entity) before the change shown in FIG. 6C. In this modified example, it is possible to reduce the sense of discomfort felt by the user when the word is changed again.

Variation 2
In this modified example, when the logo image is changed back to words, an annotation message is displayed. When the logo image is changed again (step S12), a message is displayed to the effect that the logo has been changed back to text. Fig. 11 is an explanatory diagram showing an example screen. In the example shown in Fig. 11, the CPU 11 (notification unit) displays an annotation message (notification) below the corresponding transmitted message. In this modified example, it is possible to make the user aware that the image has been changed again.

Variation 3
In this modified example, unacceptable words can be set for each logo image. Fig. 12 is an explanatory diagram showing another example of the logo image DB. In addition to the logo image DB 141 shown in Fig. 3, the logo image DB 141 includes a string of unacceptable words. The string of unacceptable words stores words that make it impossible to send a message when the word and logo image are included in the message. When determining whether the message to be sent includes unacceptable words (step S10 in Fig. 9), the unacceptable words corresponding to the logo image are also referenced to determine whether the message can be sent. In this modified example, unacceptable words can be set according to the product/service or company that uses the logo image, so that words that are unacceptable for a specific logo image can be set, although they are not unacceptable for all logo images.

Note that when making the determination, it is also possible to refer only to the string of unacceptable words in the logo image DB 141, without referring to the unacceptable word DB 142. Also, it is possible to determine which data to refer to for each logo image. On the other hand, the unacceptable words for each logo image may be integrated into the unacceptable word DB 142. For example, it is implemented as follows. A logo ID is assigned to each logo image in the logo image DB 141. A logo ID string is added to the unacceptable word DB 142, and the ID of the logo image corresponding to the unacceptable word is stored in the logo ID string. This makes it possible to associate unacceptable words with logo images in the unacceptable word DB 142. In this modified example, the logo image DB 141 also functions as a word storage unit in the present disclosure.

Embodiment 2
In this embodiment, the method of determining whether or not a message can be sent differs from that in embodiment 1. In this embodiment, the user's emotion implied in the message is estimated. If the estimated user's emotion is positive, sending of the message including the logo image is allowed. If the estimated user's emotion is negative, sending of the message including the logo image is prohibited. In this embodiment, the configurations of the SMS system 100 and the communication device 1 are the same as in embodiment 1. The processing performed by the communication device 1 is almost the same as in embodiment 1, so the following explanation will mainly focus on the differences from embodiment 1.

Figure 13 is an explanatory diagram showing an example of an emotion expression DB. The emotion expression DB 143 stores words that express emotions. The emotion expression DB 143 includes word strings, emotion strings, and weight strings. The word strings store words that express emotions. The emotion strings store emotions expressed by words. In this case, positive or negative is stored. The weight strings store the strength of the emotion expressed by the word as a weight. Hereinafter, positive will also be referred to as posi and negative as nega.

Figure 14 is a flowchart showing an example of the procedure of the judgment process. This is a process that replaces the judgment process in embodiment 1 (step S10 in Figure 9). The CPU 11 compares the words included in the message with the words stored in the emotion expression DB 143, and extracts words that express the emotion included in the message (step S21). The CPU 11 acquires the emotion and weight of the extracted words from the emotion expression DB 143 (step S22). The CPU 11 calculates the emotion score from the emotion and weight of the acquired words (step S23). For example, the weights of negative words are added up. The weights of positive words are also added up. If the same word appears multiple times, the weights of the number of times it appears are added up as a score. The CPU 11 judges whether the negative score is equal to or greater than the positive score (step S24). If the CPU 11 judges that the negative score is equal to or greater than the positive score (YES in step S24), the result of the judgment is NG (not transmittable) (step S25). If the CPU 11 determines that the negative score is less than the positive score (NO in step S24), the result of the determination is OK (transmission possible) (step S26). The CPU 11 ends the determination process and returns the process to the caller. In other words, it executes steps S11 and onward in FIG. 9.

In this embodiment, the sendability of a message containing a logo image is determined based on the user's emotions contained in the message, so even if the message contains forbidden words, it can be deemed sendable if the overall content is positive. This allows for flexibility in determining whether a message can be sent.

The judgment of whether a message containing a logo image can be sent or not may be performed by a learning model. In the learning stage, supervised learning is performed. Messages containing product names, service names, or company names from bulletin boards and SNS (Social Networking Service) published on the Internet are collected as message materials. If the logo image is a company logo, collected messages containing the name of the company are selected. For each selected message, a correct answer of whether it can be sent or not is assigned. Multiple combinations of logo images, messages, and assigned correct answers are input and trained into the learning model. After supervised learning, reinforcement learning may be performed by inputting only the logo image and message into the learning model and feeding back whether the answer output by the learning model is correct or incorrect. This completes the learning stage. The trained learning model is installed in the communication device 1. In the above judgment process, the logo image and message are given as input to the learning model. Subsequent processing is performed using the judgment result of whether it can be sent or not output by the learning model.

The technical features (constituent elements) described in each embodiment can be combined with each other, and by combining them, new technical features can be formed. The embodiments disclosed herein are illustrative in all respects and should be considered as not limiting. The scope of the present invention is indicated by the claims, not the meaning described above, and is intended to include all modifications within the meaning and scope equivalent to the claims.
