JP4598800B2 - Content conversion apparatus, content conversion method, and content conversion program - Google Patents

Description

The present invention relates to an apparatus, a method, and a program for converting content information so as not to be lost even in a specific environment such as a voice browser, a text browser, a black and white monitor, and black and white printing. Further, the present invention relates to a technique for adding and converting alternative information so that the presence of the decoration is read out even when used in a voice browser, text browser, monochrome monitor, and monochrome printing environment.

  The spread of the Internet has progressed, and as of the end of 2005, the population penetration rate of the Internet has reached 66.8%. A wide variety of websites are released from local governments to companies, and the websites are one of the important information sources in daily life. Furthermore, in recent years, it is also possible for individuals such as web log and SNS to send out information and form a social community in the world of the web. It is becoming an important foundation in social life, and anyone can use it, that is, accessibility is an important factor.

  In general, many users often obtain information visually by viewing a screen displayed on a web browser and use a mouse to select and operate the screen. On the other hand, users who cannot obtain information visually also use websites. The method uses voice reading software that reads the contents of web content by voice, and acquires information by sound (for example, see Non-Patent Document 1).

However, not all the information that can be obtained visually from web content can be obtained by voice reading software, and users of voice reading software are currently facing the problem of missing information when using web content. . In addition to voice reading software, a black and white display, a browser that displays only text, and black and white printing also have a problem that information is lost when using web content.

  As one piece of missing information, there is a decoration given to an arbitrary element in the content. For example, it is assumed that a part of the text string in the content is displayed in bold for highlighting. However, since the text-to-speech software cannot read out the character decorations, it is read out in the same manner as for the non-bold characters. Therefore, there is a problem that the emphasized part is not transmitted to the voice reading software user.

  In addition, for example, suppose that information is classified by character color, such as “Trash collection is on Monday for red letter districts and Tuesday for blue letter districts”. Since the voice-to-speech software cannot convey the color information of characters, there is a problem that the user does not know which district is in red.

The present invention can prevent the presence of a decoration from being lost even if a portion provided with a decoration in content described in a predetermined description language such as web content is used in a specific environment. It is an object to provide a content conversion device, a content conversion method, and a content conversion program.

The present invention
Content acquisition means for acquiring content described in a predetermined description language;
A decoration information extraction unit that analyzes the acquired content and extracts decoration information that is information indicating a decoration content and a decoration target that decorates the text included in the content;
Alternative information giving means for giving an explanation for reading aloud expressing the decoration content to the acquired content;
Content output means for outputting the content provided by the alternative information providing means;
The content to which the description is added is surrounded by a specific symbol so that it can be seen that the content is an additional part when displayed with a text browser that visually displays the content . It is a content conversion device.

ADVANTAGE OF THE INVENTION According to this invention, there exists an effect that the decoration added to content, such as a character color and bold type, can be read out by audio | voice reading software in the content described in predetermined description languages, such as web content.

  The best mode for carrying out the invention is the following examples.

(Client type)
FIG. 1 is a block diagram showing a content conversion system 100 having a content conversion apparatus 10 that is Embodiment 1 of the present invention.

  Embodiment 1 is an embodiment in which decoration information is converted so as to be given to the web content so that the text color decorated in an arbitrary text can be read by voice reading software in the web content. A person who browses web contents with the voice reading software is implemented in the voice reading software used. Note that “decoration” is information associated with text, and includes character thickness, font, character color, character size, character shading, underline, and the like. The “decoration information” is information indicating the decoration contents that decorate the content and the decoration target.

  The content conversion apparatus 10 includes a content acquisition unit 11, a decoration information extraction unit 12, a content conversion unit 13, and a content output unit 14, and is realized by a computer, for example.

  The content acquisition unit 11 is content acquisition means for acquiring content to be converted.

  The decoration information extraction unit 12 is an example of a decoration information extraction unit that analyzes the content acquired by the content acquisition unit 11 and extracts decoration information that is information indicating a decoration content and a decoration target that decorates the content. In the first embodiment, the decoration target is a text portion where a color is set.

  The content conversion unit 13 assigns alternative information so that the decoration content (character color in the first embodiment) can be read out by the voice reading software before and after the decoration part extracted by the decoration information extraction unit 12. Content conversion means for converting content.

  The content output unit 14 is a content output unit that outputs the content converted by the content conversion unit 13.

  FIG. 2 is a flowchart showing the operation of the content conversion apparatus 10.

  In S11, the content acquisition unit 11 acquires content to be converted. In the first embodiment, a case will be described in which an HTML document, which is one of markup languages and to which an expression indicating structure / decoration is added together with a document, is acquired as content.

  FIG. 3 is a diagram illustrating an example of an HTML document that is content to be converted in the first embodiment.

  FIG. 4 is a diagram illustrating an example in which the content to be converted is displayed on the browser in the first embodiment.

  In the first embodiment, an HTML document as shown in FIG. 3 is acquired and displayed using a general web browser as shown in FIG.

  In the content shown in FIG. 4, information about the garbage collection date is displayed. In the content, it is described that “the deficit area is the daytime collection on Tuesday, Thursday and Saturday”. If the information can be obtained visually, the “Chuo 1 Ward”, “Chuo 2 Ward”, “Seikocho 2 Ward”, “Nankocho”, “Iwato Ward”, “Oka Ward” written in red , "Tuesday, Thursday, Saturday lunch collection". However, the conventional speech-to-speech software does not read out the decoration information on the characters, but only the text content, so it is impossible to determine which ward / town is in red and the garbage collection date is unknown There is.

  Next, in S12, a location where decoration is applied is extracted based on the content acquired by the decoration location acquisition unit 12.

  FIG. 5 is a diagram illustrating a decoration list according to the first embodiment.

  In the first embodiment, as a decoration target, a text portion in which a character color is set and a character color set in the portion are extracted and stored in a storage device. As shown in FIG. A decoration list having an object (extraction location), the number of lines, and a character color is extracted. Here, the number of lines is used to determine the extraction location, but may be other than the number of lines as long as it can indicate the position in the HTML document.

  The set character color is composed of two colors: a color code and a reading phrase for the color. In HTML document rules, colors are often expressed using hexadecimal numbers following #. A color and a hexadecimal number are associated with each other, and the read-out phrase is a phrase that reads out the name of the corresponding color in hexadecimal.

  Next, in S13, the content conversion unit 13 converts the HTML document so as to read out the decoration content based on the decoration list extracted in S12, and stores it in the storage device.

  In the first embodiment, a text to be read out is added before and after the decoration portion so as to read out the character color among the decorations. In other words, it is information that is given before the decoration target, that is, information that expresses by voice that it is the start part of the decoration target, and information that is given after the decoration target and that is the end part of the decoration target. Alternative information that is information expressed by voice is added.

  FIG. 6 is a diagram illustrating an example in which the text to be read is added.

  By inserting the text “(from here)” at the beginning of the decoration part, and inserting the text “(from here)” at the end of the decoration part, the red part can be recognized even when reading aloud. In addition, by adding parentheses, it indicates that the portion inside the parentheses is an additional part when displayed in a text browser.

  In S14, the content output unit 14 outputs the HTML document converted in S13. The output destination of the converted HTML document differs depending on the system, such as a display device, a storage device, or another system via a network.

  The content acquisition unit 11 acquires an HTML document constituting the content. However, instead of the HTML document, a CSS (Cascade Style Sheet) describing a style or another markup language may be acquired.

  The decoration extracted by the decoration information extraction unit 12 is the character color set in the text, but instead of extracting the character color, the background color, underline, bold setting, etc. of the table may be extracted. . In addition to text, tables and images may be extracted.

  The content conversion unit 13 inserts text for speech reading before and after the decoration part. Instead of inserting text for speech reading, the content conversion unit 13 may insert text as an <IMG> attribute, and a buzzer sound. And so on.

  FIG. 7 is a diagram illustrating an example of an HTML document after conversion in the first embodiment.

For example, as shown in FIG. 7, “<img src =“ clear. gif ”alt =“ Akaji from here ”>” is inserted, and “<img src =“ clear. You may make it insert gif "alt =" this time ">". And you may make it display with the general browser which displays a content visually. In this case, since the text-to-speech software reads out “Akaji from here” and “Akaji from here” without displaying the text for reading aloud, it can be displayed without breaking the appearance of the content.

(Server client type)
Example 1 is an example executed on a server.

  FIG. 8 is a diagram showing a content conversion system 200 having a content conversion apparatus 40 that is Embodiment 2 of the present invention.
