Description

The disclosure of the present specification relates to an information processing device , a display control method, and a program.

When looking up a specific term using a dictionary, it is common to find a new term that you want to look up while reading a sentence explaining the meaning of the term. Assuming such a situation, some electronic dictionary terminals are provided with a jump search function for easily searching for new terms. This technique is described, for example, in Japanese Unexamined Patent Application Publication No. 2002-200012.

With the jump search function, simply by selecting a character string on the screen that displays detailed information corresponding to the term searched for in the headword search (hereinafter referred to as the headword), the user can further search for that character string. It is a function that enables By simply selecting a character string that has already been displayed, a search can be performed without key input of the character string, so the user can easily look up the meaning of the term.

JP 2011-164937 A

By the way, electronic dictionary terminals allow various types of searches. For this reason, when searching for a character string using the jump search function, before searching, the contents of the dictionary to be searched (for example, a Japanese dictionary) and the purpose of the search (for example, headline search) are different. A specification is adopted that allows the user to specify a search method from among multiple options.

However, search results do not necessarily exist for all search methods. Therefore, a situation may occur in which there is no search result even though the user is prompted to make a selection and selects it.

Although the electronic dictionary terminal has been described as an example, such a technical problem is not limited to terminals dedicated to electronic dictionaries, but may occur in general information processing apparatuses that provide a so-called jump search function for dictionary contents.

Hereinafter, each or a collection thereof will be referred to as dictionary content 14 when no particular distinction is made between individual dictionary contents.

The information processing apparatus 10 further includes an input device 15 and a display device 16, as shown in FIGS. The input device 15 is an example of an input unit of the information processing device 10, and is, for example, a keyboard. Input device 15 may also include a voice input device such as a microphone. Also, the display device 16 is an example of a display unit of the information processing device 10, and is, for example, a liquid crystal display, an organic EL (electro-luminescence) display, or the like. The display device 16 may be a display with a touch panel, and may function as the input device 15 in that case.

The information processing device 10 includes a communication module 17 as shown in FIG. The communication module 17 is an example of a communication unit of the information processing device 10, and is, for example, a wireless communication module. The communication module 17 may download dictionary content from the Internet, or add the downloaded dictionary content to the memory 12 to expand the electronic dictionary function.

In the information processing apparatus 10 configured as described above, the processor 11 executes the control program 13 developed in the memory 12 to provide an electronic dictionary function. More specifically, the processor 11 extracts information from the dictionary content 14 stored in the memory 12 according to the search conditions input by the input device 15 and displays it on the display device 16 .

1 and 2 illustrate the information processing device 10, which is a portable terminal dedicated to electronic dictionaries, the information processing device 10 may be a general-purpose portable terminal such as a smartphone, and an application The electronic dictionary function may be realized by installing . Moreover, although the case where the information processing device 10 is a portable device has been exemplified, the information processing device 10 is not limited to a portable device and may be a stationary device. Further, although an example in which the information processing device 10 includes the input device 15 and the display device 16 has been described, the information processing device 10 accesses the dictionary content in the information processing device 10 in response to a request from an external device, and performs a search. The result may be transmitted to the external device, and the information retrieved by the information processing apparatus 10 may be displayed on the display unit of the external device.

FIG. 3 shows an example of screen transitions displayed on the information processing apparatus 10 . A typical procedure for headword searching and jump searching will now be described with reference to FIG.

A screen G1 shown in FIG. 3 is an example of a home screen. In the information processing apparatus 10, when the user operates the input device 15 to press the content list while the screen G1 is displayed on the display device 16, the screen G2, which is the content list screen, is displayed on the display device 16. be done.

Furthermore, when the user operates the input device 15 to press a specific dictionary content from the content list, a screen G3, which is a search screen, is displayed on the display device 16. FIG. Here, a case is illustrated in which Japanese dictionary B is pressed as the dictionary content to be searched. Note that the transition to the screen G3 may be performed by pressing a shortcut key for specific dictionary content provided on the input device 15 .

When the user operates the input device 15 to enter the character string Str1 (“dictionary”) corresponding to the term to be searched for in the search window on the screen G3, and instructs the execution of the entry word search, a screen which is a detailed information screen is displayed. G4 is displayed on the display device 16 . Detailed information corresponding to the character string Str1 is displayed on the screen G4.

After that, if there is a term that the user wants to look up further in the displayed detailed information, the user selects the character string corresponding to the term by, for example, tracing it on the screen G4. As a result, a menu M for jump-searching for the selected character string (hereinafter referred to as a selected character string) is displayed on the display device 16 . The screen G5 is a screen when the character string Str2 (“word”) is selected, and the screen A is a screen when the character string Str3 (“kana character”) is selected.

Menu M includes one or more search method options for searching for the selected character string. Selecting one of these options executes a jump search that searches for the selected character string using the selected search method. In FIG. 3, as search method options, a button B1 corresponding to headword search, a button B2 corresponding to example sentence search, a button B3 corresponding to phrase search, and a button B4 corresponding to voice search are displayed in menu M. example is shown.

As shown in FIG. 3, in the information processing apparatus 10, the processor 11 responds to a selection operation for a character string displayed on the display device 16 while a screen G3, which is a detailed information screen, is being displayed, and selects a selected character string. The display device 16 displays a menu M including one or more search method options (buttons B1 to B4) for searching for . At this time, the information processing apparatus 10 changes the display mode of each option (buttons B1 to B4) in this menu M according to the search result of the selected character string by each of one or more search methods. That is, before displaying the menu M, the information processing apparatus 10 detects the selected character string in advance by each search method and obtains the search result. As a result, for example, options can be displayed in different display modes depending on whether search results exist or not, so the user can grasp at a glance whether or not there are search results for each option. becomes possible. Therefore, according to the information processing apparatus 10, the menu M can be displayed only by performing a selection operation on a character string, and the execution of unnecessary searches can be suppressed, so that high work efficiency in search work can be realized. can be done.

More specifically, the processor 11 causes the display device 16 to display, in the menu M, selectable detection method options for which there are search results for the selected character string, while there is no search result for the selected character string. The options of the detection method are displayed on the display device 16 in the menu M so that they cannot be selected. A screen G5 shown in FIG. 3 shows a state in which all options in the menu M are valid and selectable. On the other hand, the screen G6 shown in FIG. 3 shows a state in which the buttons B1, B2, and B4 can be selected among the options in the menu M, and the button B3 cannot be selected. As a result, it is possible for the user to understand at a glance that there is no search result for the character string Str3 "kana character" even if a phrase search is performed, and the execution of a search without search results. can be prevented. Therefore, according to the information processing apparatus 10, the execution of useless searches can be reliably prevented, so that even higher work efficiency in search work can be achieved. In addition, although the case where the character string is selected as the search target has been exemplified above, the search target is not limited to the character string. That is, the menu M may include one or more search method options for searching any search target, not limited to the selected character string. The display mode of each option in the menu M may be changed according to the search result of the search target.

The display control method for displaying the menu M for jump search will be described in more detail below.
[First embodiment]
FIG. 4 is an example of a flowchart of processing performed by the information processing apparatus 10 . FIG. 5 is an example of a sequence diagram of processing performed by the information processing apparatus 10 . FIG. 6 is a diagram showing an example of a background processing result. The display control method according to the first embodiment will be described below with reference to FIGS. 4 to 6. FIG.

When the dictionary content is selected, in the information processing device 10, the processor 11 causes the display device 16 to display a search screen (step S1). After that, when a character string is input using the input device 15 and the search button is pressed (step S2 YES), the processor 11 retrieves the character string input from the input device 15 (hereinafter referred to as a predetermined (referred to as a headword.), and searches for a predetermined headword from the dictionary contents stored in the memory 12 (step S3).

Thereafter, the processor 11 causes the display device 16 to display the detailed information corresponding to the predetermined headword read from the memory 12 (step S4). More specifically, the processor 11 reads out from the memory 12 from the dictionary content containing a plurality of combinations of headwords and detailed information corresponding to the headwords, among the detailed information corresponding to the predetermined headwords, Information for one screen is decompressed, a detailed information screen is generated based on the decompressed information, and displayed on the display device 16 .

The processor 11 also searches the dictionary contents in the background (step S5). Here, the processor 11 creates, for example, a list of terms included in the detailed information, particularly a list of terms included in the detailed information displayed on the detailed information screen. Note that the listed terms are candidate character strings that are search target candidates for the jump search, that is, search candidates. The method of creating the term list is not particularly limited. For example, the term list may be created by setting a limit on the number of characters and dividing the detailed information into all possible combinations.

When the list is created, the processor 11 retrieves each term in the list from the dictionary contents by a retrieval method corresponding to each option displayed on the menu M, and stores the result in a predetermined area (buffer area) of the memory 12. ). Search results may be stored in association with terms (candidate character strings) and search methods. The content of the search result may be the presence or absence of the search result as shown in FIG. 6(a), or the detailed information itself extracted from the dictionary content as shown in FIG. good too.

After that, when a character string included in the detailed information screen displayed on the display device 16 is selected using the input device 15 (step S6 YES), the processor 11 acquires the selected character string and stores it in the buffer of the memory 12. The area is searched for the acquired selected character string (step S7). That is, when the selected character string is selected, processor 11 specifies the search result of the selected character string based on the search result of the candidate character string and the selected character string. More specifically, a first search candidate corresponding to the selected character string is identified from the candidate character strings, and the search result of the identified first search candidate is identified as the search result of the selected character string. More specifically, search results for the selected character string are specified for each search method.

After that, the processor 11 generates a menu M for jump search (step S8), and causes the display device 16 to display the menu M (step S9). Here, the processor 11 generates the menu M so that the display form of the options in the menu M becomes a display form according to the search result in the corresponding search method obtained in step S7, and the generated menu M is displayed on the display device 16 .

As described above, in the present embodiment, after the detailed information is displayed on the display device 16 and before the selected character string is selected, the processor 11 selects the candidate character string included in the detailed information from the dictionary content. Searched by each of one or more search methods. The user selects the selected character string after reading through the detailed information display screen and recognizing the necessity of further searching for the specific term. In other words, it is assumed that there is a certain amount of time from when the detailed information screen is displayed until the user selects the selected character string. Therefore, even if a relatively large number of terms are listed as candidate character strings in step S5 and the search is repeated, the search can be sufficiently completed before the selected character string is selected. As a result, when the selection of the selected character string is detected in step S6, the buffer area of the memory 12 is accessed instead of the dictionary contents, and the search results for each search method can be obtained in a short period of time. Therefore, according to the present embodiment, it is possible to quickly display on the screen the menu M that can prevent unnecessary searches. Although an example of searching for a selected character string has been shown, the search target is not limited to character strings. An image or the like may be specified as a search target.

[Second embodiment]
FIG. 7 is another example of a flowchart of processing performed by the information processing apparatus 10 . A display control method according to the second embodiment will be described below with reference to FIG. This embodiment differs from the first embodiment in that a dictionary search is performed in the background each time the screen is scrolled to the next page after displaying the detailed information screen.

Steps S11 to S15 in FIG. 7 are the same as steps S1 to S5 in FIG. When the search of the dictionary contents in the background ends, scrolling of the screen to the next page is monitored (step S16). When scrolling to the next page is detected (step S16 YES), the processor 11 decompresses the information for one screen of the next page among the detailed information corresponding to the predetermined headword from the dictionary contents, and extracts the decompressed information. A detailed information screen is generated based on the above and displayed on the display device 16 (step S14). After that, the processor 11 creates a list of terms included in the detailed information (that is, the next page) displayed on the detailed information screen, and associates each term in the list with each option displayed on the menu M. The dictionary content is searched by the search method, and the result is stored in the buffer area of the memory 12 (step S15).

The processing from step S17 to step S20 is the same as that from step S6 to step S9 in FIG. According to the present embodiment, similarly to the first embodiment, it is possible to quickly display the menu M on the screen, which can prevent unnecessary searches.

[Third Embodiment]
FIG. 8 is yet another example of a flowchart of processing performed by the information processing apparatus 10 . FIG. 9 is another example of a sequence diagram of processing performed by the information processing apparatus 10. As shown in FIG. A display control method according to the third embodiment will be described below with reference to FIGS. 8 and 9. FIG. This embodiment differs from the first embodiment in that after the selected character string is selected, the selected character string is searched from dictionary contents by each of one or more search methods.

Steps S21 to S24 in FIG. 8 are the same as steps S1 to S4 in FIG. After the display process of step S24 is finished, the processor 11 monitors the user's selection of character strings included in the detailed information screen without performing dictionary search in the background (step S25).

When a character string included in the detailed information screen displayed on the display device 16 is selected using the input device 15 (step S25 YES), the processor 11 acquires the selected character string and extracts it from the dictionary contents of the memory 12. , the acquired selected character string is searched (step S26). More specifically, processor 11 retrieves the selected character string from the dictionary contents by each of one or more retrieval methods to obtain retrieval results.

After that, the processor 11 generates a menu M for jump search (step S27), and causes the display device 16 to display the menu M (step S28). Here, the processor 11 generates the menu M so that the display form of the options in the menu M becomes a display form according to the search result in the corresponding search method obtained in step S26, and the generated menu M is displayed on the display device 16 .

As described above, in this embodiment, after the selected character string is selected on the detailed information screen and before the menu M is displayed on the display unit, the processor 11 extracts the selected character string from the dictionary contents. Searched by each of one or more search methods. The process of retrieving only a specific character string from dictionary contents can be performed in a short period of time. Therefore, even when the menu M is generated and displayed based on the search result after the dictionary content is searched, the menu M can be quickly displayed in response to the user's selection operation. Therefore, according to this embodiment as well, it is possible to quickly display on the screen the menu M that can prevent unnecessary searches.

The above-described embodiments are specific examples for easy understanding of the invention, and the present invention is not limited to the above-described embodiments. The information processing device, the display control method, and the program can be variously modified and changed without departing from the scope of the claims.

In the above-described embodiment, as the display mode of the options in the search menu according to the search result of the selected character string, a selectable display mode and a non-selectable display mode were exemplified. Examples are not limited. For example, as shown in the screen G7 of FIG. 10, the display device 16 displays, in the menu M, selectable detection method options (button B1, button B2, button B4) for which search results for the selected character string exist. Therefore, the display device 16 may not display the detection method options for which there is no search result for the selected character string. In this case as well, it is possible to prevent useless searches for which there are no search results.

In the above-described embodiment, an example of specifying a search target by tracing a character string on the screen has been shown, but the search target may be specified by another method. For example, if the input device includes a voice input device, the search keyword may be extracted from the voice input to the voice input device. Based on the extracted search keyword, a character string selected from the character strings displayed on the display unit may be specified as a search target.

In the above-described embodiment, an example in which a single information processing apparatus provides the jump search function has been shown, but a system including a plurality of information processing apparatuses may provide the jump search function. For example, when an information processing apparatus performs a headword search, the information processing apparatus may transmit the search result to another information processing apparatus. Other information processing devices that have received the search results list all the terms in the search results and search for each term from the dictionary content. Then, the search result is transmitted to the information processing device that is the transmission source of the headword. As a result, even when a search target is specified immediately after displaying detailed information on headwords, the information processing apparatus of the transmission source can quickly perform a jump search based on the search results obtained in advance. By causing another information processing apparatus to perform such a heavy-load search process, it is possible to prevent the load on the information processing apparatus that provides the user interface from becoming excessively large. Therefore, according to a system comprising a plurality of information processing apparatuses, it is possible to provide high operability that allows users to perform searches without stress.
