Description

METHOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM FOR EXTRACTING TEXT BASED ON TAG INFORMATION}

The present invention relates to a method, a system for extracting text based on tag information of markup language used in the creation of a web page, and a computer readable recording medium for recording a computer program for executing the method. More specifically, the present invention analyzes the tag information of the markup language used for the creation of the web page, based on the extracted text when providing the text-based service such as speech conversion or translation using the extracted text in the web page A method, a system, and a computer readable recording medium for recording a computer program for executing the method, so that the text of the most suitable range is extracted.

In recent years, as the use of the Internet is becoming more common, various types of information can be obtained through the Internet. Companies that provide Internet services through Web sites provide various kinds of services to meet the needs of more and more diverse Internet users, and the types of such services are also increasing day by day.

Users are exposed to the services provided by these companies in various forms, and in particular, they want to obtain various Internet contents such as news information, dictionary information, professional information, local information, and shopping information through web sites.

Such users generally search through a web site to obtain desired content, and when the desired content is obtained from a specific web page, the user generally decodes the corresponding content mainly composed of text. However, from the user's point of view, using only text-based content may be unpleasant in the multimedia era, and in reality, as the amount of information contained in a web page increases, the user is provided in the form of text. There is also a problem in that it is necessary to keep an eye on a display means such as a monitor of a user computer until all of the text is read by the naked eye in order to decrypt the content. In addition, some users may have a multitasking desire to proceed with other tasks while obtaining desired information through the contents, but these desires have been difficult to satisfy.

In recent years, computer telephony integration (CTI) technologies, such as voice over IP (VoIP) technology, voice recognition technology, voice conversion technology, voice synthesis technology, and answering machine, have also attracted much attention. According to the technologies, it is expected that even in the Internet environment, users can enjoy advanced Internet services that provide voice instructions, voice information, and voice communications.

Accordingly, the TTS (Text To Speech) technology has been developed to solve the problem of providing text-oriented content and to widely use the CTI technology. TTS technology is a technology that can be used more widely than voice recognition technology, and is a human interface technology that converts and provides various text information into voice. TTS technology in a web page is mainly realized by extracting the text of the web page, converting it into voice, and presenting it to the user. For example, when a user stops the mouse at a certain position on a web page for a predetermined time, the word corresponding to the position of the mouse pointer is extracted according to a mouse-over event. Alternatively, it may refer to a case in which a user drags a portion of text on a web page and converts it to a voice.

However, TTS services through web pages, which are currently realized, are not a complete human interface technology. Specifically, the current TTS service has no choice but to convert only the words of the locations recognized by the user's mouseover into speech, or allow the user to directly drag the mouse to designate as much text as desired. There was a problem. In the former case, unlike the user's intention, only the mouseover word is uniformly converted into voice. In the latter case, in order for the user to convert the text of the desired range into speech, the user must roughly decode the text and then designate the text range to be converted into speech. There was a problem in that the subject matter of the TTS technology intended to exclude the case that should be decoded as much as possible, and also takes additional time to the above designation.

In addition, in order to avoid the above problems, if all the text in the web page is extracted and provided with the TTS service based on this, there may be a problem that even the text of the area that the user does not want to extract.

If a specific area of the web page is designated to enhance the user's convenience, and the text is extracted to include a button for providing the TTS service in the web page, the existing web page is implemented to implement the TTS service. There may also be difficulties in making extensive corrections.

Therefore, a technique for improving user convenience by solving all the above problems is required.

The present invention aims to solve all the problems of the prior art described above.

In addition, an object of the present invention is to analyze tag information of a markup language used for creating a web page and to actively extract text based on the tag information.

Meanwhile, an object of the present invention is to analyze tag information of a markup language used for creating a web page and to extract text of various different ranges based on this.

In addition, the present invention is to extract the text from the web page, so that the user does not need to perform a cumbersome user operation, such as mouse dragging, it is not necessary to specifically modify the web page.

Another object of the present invention is to enable a user of a web page to conveniently obtain voice data converted from extracted text.

The configuration of the present invention for achieving the above object is as follows.

According to an aspect of the present invention, there is provided a method of extracting text based on tag information of markup language used to create a web page, the method comprising: recognizing a text pointer on a web page, the text pointer in the web page; A method is provided for determining whether at least one tag pair surrounding the text pointed to is a tag pair for extraction of predetermined text, and extracting the text surrounded by the tag pair determined in the determining step.

According to another aspect of the present invention, there is provided a system for extracting text based on tag information of a markup language used for creating a web page, the system comprising: a text pointer recognition unit for recognizing a text pointer on a web page; A tag pair determination unit for determining whether at least one tag pair surrounding the text pointed by the text pointer is a tag pair for extracting predetermined text, and text for extracting text surrounded by the tag pair determined by the tag pair determination unit A system is provided that includes an extraction unit.

In addition, according to the present invention, a computer-readable record for extracting text of a web page and / or recording another method, system for providing a TTS service based on the extracted text, and a computer program for executing the methods. Medium is further provided.

According to the present invention, it is possible to extract the text in the web page in accordance with the user's intention, and provide a TTS service based on this.

In addition, according to the present invention, by automatically extracting the text according to the characteristics of the web page to provide a TTS service, it is possible for the user to easily obtain the information of the web page, and improve the user's access to the web page. .

On the other hand, according to the present invention, it is possible to extract the text on the web page without modifying the old web page, and to provide a TTS service based on this.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Configuration of the entire system

1 is a view showing a schematic configuration of a TTS service providing system according to an embodiment of the present invention.

As shown in FIG. 1, the TTS service providing system according to an exemplary embodiment of the present invention may include a user computer 100 and a TTS server 300. Here, the user computer 100 and the TTS server 300 may communicate through various network environments such as a local area network (LAN) or a long-distance network (WAN) using a dedicated line. This network environment may be the known World Wide Web (WWW).

Meanwhile, the TTS server 300 is a server for providing a TTS service (ie, a service for converting text included in a web page into voice), and the TTS conversion unit 310 in the TTS server 300. Can perform the process of converting the text to speech. The TTS server 300 may be a web server of an Internet portal site, or may be an operation server of a company that specializes in providing only TTS services. The TTS server 300 may interactively communicate with one or more user computers 100 through an Internet protocol in a known network environment. In addition, the TTS server 300 may perform the necessary processing by referring to the speech conversion database 500 in response to a request from the user computer 100.

The voice conversion database 500 stores information on voice data corresponding to a specific text.

Configuration of Your Computer

FIG. 2 is a diagram illustrating a detailed configuration of a user computer 100 in the TTS service providing system of FIG. 1.

As shown in FIG. 2, the user computer 100 may include an operation unit 110, a tag information database 130, a program storage unit 150, a user input unit 170, and an output unit 190.

The operation unit 110 may include a mouseover recognition unit 111, a tag pair determination unit 113, a text extraction unit 115, a text transmission unit 117, and a voice data providing unit 119. According to an exemplary embodiment of the present invention, the mouseover recognition unit 111, the tag pair determination unit 113, the text extraction unit 115, the text transmission unit 117, and the voice data providing unit 119 are at least one of them. Some may be included in the calculator 110 or program modules communicating with the calculator 110. Such program modules may be included in the operation unit 110 in the form of an operating system, an application program module, and other program modules, and may be physically stored on various known storage devices. In addition, these program modules may be stored in a remote storage device that can communicate with the operation unit 110. Meanwhile, such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or execute particular abstract data types, which will be described later, according to the present invention.

The tag information database 130 includes a tag surrounding a text pointed by a mouse pointer among markup languages used for creating a web page having a predetermined identifier (for example, a URL) as described in detail below. Information on whether the pair is a tag pair for extracting a predetermined text is stored, and the operation unit 110 may refer to the tag information database 130 as necessary. Although the calculator 110 and the tag information database 130 are illustrated as separate components in FIG. 2, the tag information database 130 may be included as one component in the calculator 110. In addition, the tag information database 130 according to the present invention, as long as it is used to realize individual embodiments of the present invention, is not necessarily a user computer 100, for example, an external device such as the TTS server 300. It may also be included. However, in this case, since the TTS server 300 should be referred to when extracting text from the calculation unit 110, it is true that the configuration as shown in FIG. 2 is more preferable according to the need of efficient calculation.

In addition, the operation unit 110 further includes a program driver (not shown), which is a program stored in the program storage unit 150, that is, a program for extracting text and providing a TTS service according to the present invention. It can also be driven together at run time. The program storage unit 150 does not necessarily need to be included as a component of the user computer 100, but may be a computer-readable recording medium, that is, a hard disk, a floppy disk, a floppy disk, a magnetic tape, a CD-. It may be replaced by a recording medium such as a ROM or a DVD.

The user input unit 170 may be a conventional computer input means, that is, a keyboard or a mouse, and the like, and the output unit 190 outputs a computer monitor or text for voice to visually display a web browser display and / or a web page display. It can be implemented as a speaker that can.

For reference, each component of FIGS. 1 and 2 may communicate with each other as needed, but will not be specifically illustrated for known communication means for the communication.

Text Extraction and Speech Conversion

Hereinafter, referring to FIGS. 1 to 3, a process of extracting text from a web page and a process of converting the extracted text into voice and outputting the same will be described. 3 is a flowchart illustrating a process of extracting a text of a predetermined region, converting the text into a voice, and then outputting it when a mouseover is performed on text included in a web page according to an exemplary embodiment of the present invention.

When a user executes a web browser using the user computer 100, a program for extracting text, converting the extracted text into voice, and outputting the same is driven according to an embodiment of the present invention. As described above, this program may be recorded in the program storage unit 150 in the user computer 100, or may be recorded in a separate recording medium.

Thereafter, the user can connect to the Internet and visit a web page having a predetermined URL through an activated web browser. On the other hand, a number of servers provide content that can be viewed through a web browser, the URL is usually used to indicate their location. This URL is intended to specify the location of the files on each of the servers on the Internet, but since the URL has a relatively freely definable property, other information may be used to characterize the web page (e.g., Information about a tag pair for extracting a predetermined text according to an embodiment) may also be included. In either case, the URL or part of the URL may correspond to information about tag pairs for extraction of certain text according to the present invention.

Such web pages are typically written in a markup language (eg, HyperText Markup Language (HTML), eXtensible Markup Language (XML), eXtensible HyperText Markup Language (XHTML), etc.). The markup language is a programming language used to create web pages. Among them, HTML, which is widely used, is a language developed for writing hypertext on a web document. The markup language includes instructions for defining font size, font color, font shape, graphics, document movement (hyperlink), and the like on a web page. Commands used in the markup language are collectively called tags, which are characterized by a pair of two tags that mark the beginning and end. In this specification, this is referred to as a tag pair.

Countless kinds of web pages, which are now widely distributed, are implemented by web documents written in such markup language, and the web browser interprets them to provide a visually comfortable user experience. That is, a web document written in such markup language and a tag pair included in the markup language allow a user to view web pages of various configurations.

Referring to FIG. 3, a process of extracting text from a web page and outputting data obtained by voice conversion will be described with reference to FIG. 3.

First, when the user places the mouse pointer on the text included in the web page, which is displayed by the web browser of the user computer 100, in step S310, the mouseover recognition unit 111 of the operation unit 110 performs the mouseover. Determine whether an event has occurred. In general, when the user wants to be provided with the TTS service according to an embodiment of the present invention, the mouse is continuously positioned for a predetermined time or more on the corresponding text. Accordingly, the mouseover recognition unit 111 may recognize that the mouseover event has occurred when the mouse pointer is stopped for a predetermined time or more on arbitrary text.

In step S330, the tag pair determination unit 113 determines whether the tag pair surrounding the current mouseover text is the final tag pair for text extraction, and detects the final tag pair based on the determination result. . In this regard, it will be described in more detail with reference to FIG. 4 as follows.

The tag pair determination unit 113 recognizes the lowest tag pair that is closest to the pointed text once (step S410), and determines whether the tag pair is a tag pair that determines the range of text to be finally extracted from the corresponding position of the web page. Determine (step S430). In this case, the tag pair determination unit 113 may refer to information stored in the tag information database 130, that is, whether a predetermined tag pair of a web page is a tag pair indicating text extraction. If the lowest tag pair is indicated in the tag information database 130 as being not a tag pair for text extraction, the tag pair discrimination unit 113 determines such a tag pair for the upper one step surrounding the lowest tag pair. The process is repeated (step S431), and this continues until a tag pair for text extraction is detected. That is, the determination continues from the lowest tag pair surrounding the pointing text to the highest tag pair in order to determine whether the tag pair is a tag pair for text extraction, and if such a pair of tag pairs for text extraction is detected, the process is repeated. It stops (step S433). On the contrary, if the lowest tag pair is a tag pair for text extraction, the tag pair discrimination unit 113 stops further discrimination processing (step S433).

For example, if you have text written in the markup language called "<p> Why is there no Nobel prize? </ P>", and the mouse pointer is at the "upper" position in the text when the mouseover event occurs, the tag The pair discrimination unit 113 determines whether the text pointed by the mouse pointer, that is, the <p> and </ p> tag pairs that are the lowest tag pairs surrounding the 'up' is the final tag pair for text extraction. . In this case, when referring to the tag information database 130, if it is confirmed that the tag pairs <p> and </ p> are tag pairs for text extraction, further determination processing is stopped. On the contrary, if the tag pairs <p> and </ p> are not tag pairs for text extraction, the determination process is repeated for the tag pairs up one step.

In step S350, the text surrounded by the tag pair determined by the tag pair determination unit 113 in step S330 is extracted. This step is performed by the text extraction unit 115. Referring to the above example, if the tag pair determination unit 113 determines that the tag pairs <p> and </ p> are the tag pairs for the final text extraction, the 'Well Nobel Prize' is the text surrounded by the tag pairs. Is not there? '

In step S370, the text transmitter 117 transmits the final text extracted in step S350 to the TTS server 300. The TTS conversion unit 310 of the TTS server 300 converts the received text into speech by referring to the speech conversion database 500 that stores information necessary for converting text into speech, and then converts the received text into speech. Resend to. The voice data corresponding to each text code may be stored in the voice conversion database 500, or voice data corresponding to the detailed syllables of the actual text may be stored.

In step S380, the user computer 100 receives voice data transmitted from the TTS server 300, that is, the TTS conversion unit 310 of the TTS server 300 receives data converted from text into voice, In operation S390, the received voice data is provided by the voice data provider 119 of the calculator 110. The voice data may be output to the user by an output unit 190 such as a speaker.

Hereinafter, with reference to the configuration of the tag information database 130, which is one of the main components of the TTS service providing system according to an embodiment of the present invention, as described above, the tag information according to an embodiment of the present invention Let's take a closer look at how to analyze and determine whether to extract text.

Tag information database

As is well known, web pages that a user can use a user's computer 100 to run a web browser and access a web site are available, including the description of the underlying markup language and the tags used. Depending on the appearance will have a variety. For example, the main page of a portal site is divided into many areas (eg, title area, banner area, video area, etc.), each area containing a plurality of short texts, each short text having a different web. Hyperlinks can be included to link to pages. In addition, in a web page such as an encyclopedia, an area for displaying a search word and a description area for the search word may be divided. Meanwhile, a web page representing an online bulletin board may be divided into an area indicating a bulletin board classification and an area indicating a bulletin board content, and an area indicating the bulletin board content may be divided into a plurality of areas for each title of the bulletin board.

Most of these visually divided areas contain texts that are not related to each other, and users are provided with text-based services. In this case, unrelated texts are extracted independently from each other. I prefer to bundle them together and then convert the extracted text into voice. On the other hand, a user may want to be provided with a text-based service based on texts that are related to each other even if the texts that are language-divided such as sentences or paragraphs are related to each other. In addition, the user may want to extract the texts of the visually separated areas within the web page separately and receive a service based on the texts.

The division of the visual area within a web page written in a given markup language is made possible mainly by the use of tags. Thus, in extracting text, if it is extracted only within a range within a specific tag pair, the text in each area of the visually separated web page can be extracted separately. In addition, even if there is a tag pair that separates sentences or paragraphs, if the tag pair is not a tag pair for extracting a predetermined text from the corresponding area, the classification by the tag pair is ignored and all the text in the wider area can be extracted. have.

According to an embodiment of the present invention, the tag information database 130 may store information on whether a specific tag pair is a tag pair for extracting a predetermined text. For example, tag pairs <p> and </ p> are not tag pairs for extracting predetermined text, and only tag pairs <div> and </ div> that are one level higher than that are tag pairs for extracting predetermined text. For example, if the information of the pair is stored in the tag information database 130,

<div class = 'knCnt' style = 'overflow: hidden; word-wrap: break-word; word-break: break-all;'>

Mathematics is closely related to science and is an important discipline that many disciplines need.

Why are there no Nobel prizes?

</ div>

In a web page written in a markup language, the tag pair discrimination unit 113 extracts text from the tag pairs <div> and </ div> that are one level higher than the lowest tag pairs <p> and </ p>. And the text surrounded by the tag pairs <div> and </ div> may be extracted by the text extractor 115.

Meanwhile, information on which tag pair is a tag pair for extracting a predetermined text may vary according to the characteristics of the web page as necessary. Accordingly, the tag information database 130 may be configured for each web page or for each characteristic of the web page. Different information can be stored. For example, for a web page that contains news articles, extracting the full text including the title of the news article at once and performing a voice conversion or translation may be in line with the user's needs, so that the top page containing all text Only tag pairs of may be designated and stored as tag pairs for text extraction. Meanwhile, in the case of an encyclopedia web page, a search word and a description part thereof may be visually separated into different areas, but a tag pair for extracting a predetermined text may be specified to extract only the search word and the description part thereof. will be.

In the case of Naver ^TM , the well-known portal site of the applicant, each web page is described by various tag pairs, among which, a pair of tags which can be used as a tag pair for extracting a predetermined text according to several types of web pages and Breaking down the tag phases that do not are as shown in the following table:

As such, the information on the tag pair for extracting the predetermined text stored in the tag information database 130 may be changed as necessary or in accordance with a change in user's preference.

Example of Extracting Text Using Tag Information

Hereinafter, an example of performing text extraction using tag information stored in the tag information database 130 according to an embodiment of the present invention will be described in detail.

For convenience of explanation, it is assumed that there is a web page as shown in FIG. 5. The lower part (question part) of the content of the web page of FIG. 5 consists of the following markup languages.

<div class = 'knCnt' style = 'overflow: hidden; word-wrap: break-word; word-break: break-all;'>

Mathematics is closely related to science and is an important discipline that many disciplines need.

Why are there no Nobel prizes?

<P> Please write more about the Fields Award </ P>

<P> The Nobel Prize in mathematics is la ... </ P>

</ div>

In the tag information database 130, it is assumed that tag pairs <div> and </ div> are designated and stored as tag pairs for text extraction in association with at least a part of the identifier of the web page of FIG. 5. It is also assumed that the mouse pointer points to 'no' for 'Why No No No Prize?'

First, as described above, since the lowest tag pair surrounding 'none', which is the text pointed by the mouse pointer, is <p> and </ p>, it is determined whether they are tag pairs for text extraction. However, since the tag pair is not found even with reference to the tag information database 130, discrimination of <div> and </ div>, which is one step higher, is performed. As mentioned above, since the tag pair is designated as a tag pair for text extraction, the text surrounded by the tag pair is a text extraction target according to an embodiment of the present invention. Accordingly, the web page is surrounded by a pair of tags <div>, </ div>,
