Abstract

PROBLEM TO BE SOLVED: To efficiently save text data (alternative text) for enabling search for imaged text displayed by an image file in a markup document stored in a Web server. A text data storage device is provided. An image file specified from an image tag included in a markup document such as an HTML file is scanned to recognize text data specifying the imaged text displayed by the image file, and the image data is recognized. In contrast to the alternative text included in the tag, if it does not match, the recognized text data is saved as the alternative text, so that even if the image file is replaced due to revision of the web page etc., the replaced image The imaged text displayed by the file can be searched by the alternative text, and can be included in the search target without omission. [Selection] Figure 8

Description

The present invention, in the mark-up document, such as HTML files that have been stored in the Web server, save the text data for enabling search for text, such as letters and numbers that are thus displayed in the image file, text data storage device, The present invention relates to a text data storage program and a text data storage method.

  In a Web server that provides various information on the Internet, a markup document that is a file described in a markup language such as HTML or XML used when displaying a Web page, an image file that displays an image, Various files constituting the Web page such as an include file such as JavaScript (registered trademark) are stored. A user obtains necessary information by operating a terminal such as a personal computer or a smartphone to start a Web browser, reading a markup document or an image file from a Web server, and displaying a Web page on the terminal. Yes.

  Web pages are mainly composed of text and images such as letters and numbers, but texts such as letters and numbers displayed on the Web page are described as text data in the source code of the markup document. Therefore, the characters and numbers displayed on the Web page can be searched for text data described in the source code of the markup document, but the problem here is the image displayed on the Web page. This includes a case where text such as letters and numbers which are imaged is included. Such imaged text is displayed by an image file, but the image file does not contain searchable text data, and cannot be used as a search target as it is.

  For example, when a cross-sectional major revision occurs on a website of a company or the like, a text search of a file stored in a web server is performed by a technique called grep in order to specify a portion to be corrected without omission. As described above, since the imaged text is not a target of search, there is a problem that even if the image includes text to be corrected, it is overlooked.

  In general, a method of defining alternative text in the alt attribute of an HTML file is used to deal with such a problem. For example, in the Web page shown in FIG. 1, the free dial symbol and the telephone number “0120-999-999”, and the “reception time / 24 hours 365 days” portion below it are output by outputting an image file. Is displayed. That is, it is assumed that the characters and numbers displayed in this part are imaged text.

  FIG. 2 shows the source code of the HTML file in the “inquiry” frame portion of the example shown in FIG. 1, and among these, the image portion including the above text is designated by the image tag. FIG. 3 shows a portion and an image tag displayed by outputting an image file and displayed by the image file.

  The image tag shown in FIG. 3 includes “toll-free 0120-999-999” as an alt attribute (alt =) as well as address information (./imgs/autoaway.gif) specifying the storage area of the image file. The alternative text "Time 24 hours 365 days" is defined. In this way, when the alternative text is defined in the image tag, as shown in FIG. 4, when the cursor is placed on the image portion, the text information (free dial 0120-999-999 reception time 24 hours 365 days) is displayed. In addition to being displayed, if the source code of an HTML file that is a markup document is searched, the imaged text included in the image file can be included in the search target.

  However, in order to describe alternative text in the alt attribute in this way, the creator of the web page has to search for the image tag included in the markup document and individually edit it. If a person does not know this function, overlooks the existence of an image tag, or does not describe the work because it is troublesome, the imaged text of that part will be leaked from the search target.

  As a technique for dealing with such problems, for example, an image tag is automatically extracted from an HTML file so that even an unfamiliar person with web page creation can easily edit the alt attribute. An invention is disclosed in which an image of an image file designated by the above is displayed and the text displayed in the image is input to a computer, and the input text is written as an alternative text in the alt attribute (see Patent Document 1). ).

JP 2008-117125 A

  If the invention disclosed in Patent Document 1 is used, even those who are not accustomed to creating a Web page can easily edit the alt attribute, but still visually check the image for each image tag and edit the text. It is necessary to input, and complicated work will occur. In particular, when building a Web site composed of many Web pages, it is assumed that the amount of work becomes enormous.

  In addition, when a part of an existing website is revised instead of constructing a new website, the alt attribute must be edited for some image tags to be revised. Nevertheless, according to the invention disclosed in Patent Document 1, since all image tags including those not subject to revision are subject to confirmation work, the revision work becomes extremely inefficient. Conceivable.

The present invention has been made to solve the above problem, the markup document such as an HTML file stored in the Web server, images of text or the like numerals are thus displayed in the image file An object of the present invention is to provide a text data storage device, a text data storage program, and a text data storage method capable of efficiently storing text data (alternative text) for making text searchable. It is.

An alternative text included in an image tag for specifying the image file included in the document is updated to text data recognized by scanning the image file selected by the image file selecting unit, and the markup document updating unit Is stored in the Web server in the Web server The second markup document may also be characterized in that for updating the markup document alternate text is updated to be included in the image tag by the alternate text updating means.

  With this configuration, if the text alternative for an image file identified from an image tag is inappropriate, text alternatives for other image tags that target the same image file are also automatically corrected. Therefore, it is possible to improve the efficiency of storing appropriate text data as alternative text in the image tag.

  The markup document selection unit may select a markup document updated or created within a predetermined period from the markup documents stored in the Web server. it can. The image file selection unit selects an image file updated or created within the period from among image files specified from image tags included in the markup document selected by the markup document selection unit. It is good.

  With this configuration, not all markup documents stored in the Web server, but only markup documents updated within a certain period, and more specifically, image files updated within a certain period are narrowed down and processed. Therefore, it is possible to further improve the efficiency of the process of storing appropriate text data as alternative text.

  The present invention can also be specified as an invention relating to a text data storage program provided in the text data storage device according to the present invention.

  Embodiments for carrying out the present invention will be described below in detail with reference to the drawings. In addition, the following description shows an example of embodiment of this invention, Comprising: This invention is not limited to this embodiment. For example, in the following embodiment, an HTML file described in HTML will be described as an example of a markup document in the present invention. However, the markup document in the present invention is not limited to an HTML file, but an XML file or the like. A markup document described in another markup language may be used.

  FIG. 5 shows an example of an embodiment of a text data storage device according to the present invention. A user who operates a user terminal that can be connected to the Internet, such as a personal computer, a smartphone, or a tablet terminal, starts a Web browser on the user terminal, connects to a Web server via the Internet, reads a Web page, and reads various information. Browse.

  Web pages are configured by markup documents written in markup languages such as HTML and XML, image files, include files such as JavaScript (registered trademark), and the like. Stored. When the Web server receives the request specifying the URL from the user terminal, the corresponding file is read and transmitted to the user terminal.

  Normally, when an image is displayed on a web page, the HTML file of the web page includes an image tag, and the image tag includes a URL or file name in which the image file of the image to be displayed on the web page is stored. Address information such as is specified. When the HTML file is read out to the user terminal, the image file specified from the address information is also read out to the user terminal, and the image is displayed on the Web page by outputting the image file.

  The image displayed on the Web page in this way may include not only photographs, figures, patterns, etc., but also imaged text such as letters and numbers. In this case, the present invention is used to store searchable alternative text in an image tag corresponding to an image file so that the imaged text displayed on the Web page can be searched. A text data storage device.

  What is an image file that contains imaged text and what image tag corresponds to that image file, and how alternative text that can be searched for in the image tag is defined as the alt attribute? As described in the prior art with reference to FIGS.

  5 and 6 show a text data storage device according to the present invention, a text data storage server connected via a network to a Web server storing a target markup document (in these examples, an HTML file). However, the present invention is not limited to such a configuration. For example, the text data storage device according to the present invention may be provided in the same computer as the Web server as a partial function of the computer constituting the Web server.

  FIG. 6 shows an example of the configuration of the text data storage device according to the present invention. The text data storage server 10 corresponds to the text data storage device according to the present invention, and the text data storage server 10 is connected to the Web server 20 via a network, but these may be configured as an integrated computer. The good thing is as explained above.

  Further, the text data storage server 10 and the Web server 20 are not required to be physically configured by one computer, and a plurality of computers may be linked to realize necessary functions. Alternatively, these functions may be realized as a part of the functions of one computer having other functions.

  The text data storage server 10 is configured by a computer having an auxiliary storage device such as a CPU, main memory, and HDD, and corresponds to each function stored in the auxiliary storage device such as an HDD in order to realize a predetermined function. The application program to be read is read into the main memory or the like, and the arithmetic processing is executed by the CPU using the main memory or the like as a working area.

  The text data storage server 10 includes an HTML file selection unit 11, an image file selection unit 12, a text recognition unit 13, an alt reading unit 14, a matching processing unit 15, an HTML file selection unit 16, an alt writing unit 17, and an HTML. Although the file update unit 18 is provided, each of these units is functionally specified, and each function is an application program corresponding to each function stored in an auxiliary storage device such as an HDD. This is realized by reading out to the main memory or the like and executing arithmetic processing by the CPU using the main memory or the like as a working area.

  As the Web server 20, a server computer that can be connected via the Internet from a user terminal that can be connected to the Internet using a Web browser such as a personal computer, a tablet terminal, or a smartphone is used. The Web server 20 is configured by a computer including an auxiliary storage device such as a CPU, main memory, and HDD, and an application corresponding to each function stored in the auxiliary storage device such as an HDD in order to realize a predetermined function. The program is read into the main memory or the like, and the arithmetic processing is executed by the CPU using the main memory or the like as a working area.

  The Web server 20 is provided with an HTML file storage unit 21 that stores an HTML file that configures a Web page, and an image file storage unit 22 that stores an image file that configures a Web page. Each of these units is assigned a predetermined storage area of an auxiliary storage device such as an HDD, but in addition, a storage area for storing other files constituting a Web page such as an include file is usually provided. .

  For the HTML file stored in the HTML file storage unit 21 and the image file stored in the image file storage unit 22, metadata including history information such as the creation date / time and the latest update date / time of each file is stored. . The method for storing the metadata is not particularly limited. For example, the metadata may be stored in a header or the like as a part of each file. It is also possible to manage each file separately.

  Based on the above configuration, the flowchart of FIG. 7 and examples of three patterns for checking and storing whether or not an appropriate alternative text is stored in the image tag according to the present invention shown in FIGS. 8 to 10 are used. The processing flow of the text data storage program according to the present invention that operates in the text data storage server 10 will be described.

  First, the HTML file selection unit 11 of the text data storage server 10 is activated, and the HTML file updated after the previous activation from the HTML file storage unit 21 of the Web server 20 and a new one after the last activation. The created HTML file is selected, and the selected HTML file is read from the HTML file storage unit 21 (S01).

  The timing at which the HTML file selection unit 11 is activated is not particularly limited. For example, the HTML file selection unit 11 may be activated at a timing set in the HTML file selection unit 11 such as what time every day or what day of the week. May be activated at any timing such as pressing an activation button. In these examples, in order to select an updated or newly created HTML file, the latest update date / time (created date / time in the case of new creation) included in the metadata of each HTML file is searched. However, in order to improve the efficiency of the process for such selection, an update history including the latest update date and time of each HTML file stored in the HTML file storage unit 21 is separately managed as log data. It is suitable to leave.

  Alternatively, the HTML file storage unit 21 is monitored in the Web server 20, and the text data is saved when the HTML file stored in the HTML file storage unit 21 is updated or when a newly created HTML file is stored. The server 10 may be configured to send a signal serving as an activation command for the HTML file selection unit 11. In the case of such a configuration, the HTML file that is the target of sending a signal serving as a start command is selected as an updated or newly created HTML file.

  For the image file specified from the image tag included in the HTML file, only the file data is updated without changing the file name or the storage area address, and the HTML file itself is not changed. Even if the imaged text displayed by the image file is added, deleted, or changed, there may be a problem that such a change cannot be detected from the update history of the HTML file. In order to cope with such changes, not only the update history of the HTML file itself, but also the fact that the image file specified from the image tag included in the HTML file has been updated is recorded as the update history. Thus, it is preferable to manage log data.

  Subsequently, one HTML file is selected from the HTML file read from the HTML file storage unit 21 (S02), the source code of the selected HTML file is read, and it is confirmed whether an image tag is included (S03). . If the selected HTML file does not include an image tag, if all the HTML files read from the HTML file storage unit 21 have not been processed (S14), one other HTML file is selected. (S02), similar processing is repeated.

  If the selected HTML file includes an image tag, the image file selection unit 12 is activated to select an image file specified from the file name or address information specified in the image tag, and the Web server 20 It is read from the image file storage unit 22 (S04), and it is confirmed whether there is a change in this image file (S05).

  Here, in order to determine whether or not there is a change in the image file, it is updated or newly created since the last startup from the update history such as the update date and time of the image file, as in the case of the HTML file. Although the image file can be specified, even if the image file itself is not updated or newly created, the imaged text displayed on the Web page by changing the file name included in the image tag is not displayed. Since it may be changed, it is preferable to add not only the update date and time of the image file but also whether or not the file name included in the image tag has been changed.

  If there is no change in the image file, if processing for all the HTML files read from the HTML file storage unit 21 has not been completed (S14), one other HTML file is selected (S02), and the same Repeat the process. If the target HTML file includes a plurality of image files, if there is no change in all the image files, the process of S14 is performed. If even one image file is changed, the image file is changed. The process of S06-S13 demonstrated below is performed.

  When there is a change in the image file (when the image file is updated, when a new image file is added, or when the image file specified by the image tag is changed), the text recognition unit 13 is changed. It starts, scans the image file (scans the image output by the image file) (S06), and executes a process of recognizing text such as imaged characters and numbers displayed on the image (S07). ).

  The processing method when the text cannot be recognized is not particularly limited. For example, an image file that cannot recognize the text is recorded in the hold list, and the image file recorded in the hold list is displayed on the computer display. It is only necessary that the administrator confirms whether the administrator visually includes text such as letters and numbers, and edits the alt attribute as necessary.

  If the text data can be identified by recognizing the imaged text, the alt reading unit 14 reads the alternative text defined in the alt attribute from the image tag specifying the target image file (S08). ). Further, the matching processing unit 15 is activated, and the text data specified from the imaged text previously recognized by the text recognition unit 13 is compared with the alternative text read by the alt reading unit 14 (S09). If they match, it is considered that an appropriate alternative text that matches the imaged text is defined in the alt attribute of the image tag, so there is no need to re-edit the alt attribute.

  On the other hand, if they do not match, it is necessary to re-edit the alt attribute. Here, the HTML file selection unit 16 is activated to read the text data specified from the recognized imaged text. The HTML file storage unit 21 of the Web server 20 is searched for another HTML file that includes an image tag that identifies an image file that does not match the alternative text (S10), and if there is a corresponding HTML file (S11) The HTML file is selected and read out from the HTML file storage unit 21 (S12). When a plurality of HTML files are hit by this search, all the HTML files are selected and read.

  Subsequently, the alt writing unit 17 is activated, and the image file is scanned for the alternative text defined in the alt attribute of the corresponding image tag included in all the HTML files including the first read HTML file. To the text data specified from the recognized text. Furthermore, the HTML file update unit 18 is activated, the HTML file with the modified alt attribute is uploaded to the Web server 20, and each HTML file stored in the HTML file storage unit 21 is updated (S13).

  When there is no HTML file hit by the search (S11), the alternative text defined in the alt attribute of the corresponding image tag included in the first read HTML file is identified from the text recognized by scanning the image file. The HTML file corrected to the text data and the alt attribute corrected is uploaded to the Web server 20 to update each HTML file stored in the HTML file storage unit 21 (S13).

  Even if the same image file is used without performing the processing shown in S10 to S12, it is possible to perform processing such as image file selection and scanning for each HTML file. When the processing shown in S12 is performed, it is not necessary to read and scan the same image file from the image file storage unit 22 of the Web server 20 many times, so that more efficient processing is possible.

  8 to 10 illustrate three patterns that can be generated in the processes of S06 to S13. In FIG. 8, an image including the imaged text “Ah” is displayed on the Web page displayed by the file 1, and an appropriate alternative text “Ah” is defined in the alt attribute. This image has been changed to an image that contains the imaged text “Yes”, but the alternate text defined in the alt attribute has also been changed to “Yes”, so the text that scanned the image file The alternative text of the alt attribute included in the data and the image tag matches. That is, with the change of the image file, it is considered that the alt attribute is also changed and an appropriate alternative text is stored, so that it is not necessary to edit the alt attribute.

  In FIG. 9, an image including the imaged text “UU” is displayed on the Web page displayed by the file 2, and the alt attribute of the image tag corresponding to the image is also appropriately set to “UU”. Where the alternative text was defined, the alternative text defined in the alt attribute remains "Uu" even though this image was changed to an image containing the imaged text "Yes" And there is a change omission. When the image file of this image is scanned and the text data specifying the imaged text “Yes” is recognized, and the alternative text of the alt attribute included in the image tag “Uu” is compared, Does not match, it can be confirmed that although the image file has been changed, the alt attribute is not changed and the appropriate alternative text is not saved.

  In such a case, in addition to the file 2, the HTML file storage unit 21 of the Web server 20 is searched to read out the file 3 in which the same image file is used, and the image tags of both the file 2 and the file 3 are read out. Change the text alternative defined in the alt attribute to “Yes”, upload the saved files, and update the files 2 and 3 stored in the HTML file storage unit 21 of the Web server 20. To do.

  In FIG. 10, the file 4 is newly created, and an image including the imaged text “Oo” is displayed on the Web page displayed by the file 4, but the image tag alt corresponding to the image is displayed. The definition of alternative text is missing in the attribute, and nothing is described. When the image file of this image is scanned, text data that identifies the imaged text "Oh" is recognized, but no alternative text is defined in the alt attribute of the image tag that identifies this image file, Since they do not match, it can be confirmed that an appropriate alternative text is not stored in the alt attribute of the displayed image.

  In such a case, in addition to the file 4, the HTML file storage unit 21 of the Web server 20 is searched to read the file 5 in which the same image file is used, and the image tags of both the file 4 and the file 5 are read. Each of the files stored by defining the alternative text “Oo” in the alt attribute included in the URL and uploading the files is updated, and the files 4 and 5 stored in the HTML file storage unit 21 of the Web server 20 are updated.

  For the previously selected HTML file described above, if the image file contains text that has been imaged, the text data of the text is appropriately stored in the alternative text of the alt attribute, and text search is performed. When the processes of S06 to S13 to be enabled are completed, if all the HTML files read from the HTML file storage unit 21 are not completed (S14), one other HTML file is selected (S02). Repeat the same process. When the processing for all the HTML files is finished, the processing by the text data storage program according to the present invention is finished.
