Description

  The present invention relates to a method and system for extracting text based on the characteristics of a web page, and a computer-readable recording medium. More specifically, the present invention extracts a text in a web page, and then uses this to provide a service based on text, such as speech conversion and translation, according to the characteristics of the web page, The present invention relates to a method, a system, and a computer-readable recording medium for extracting different ranges of text such as sentences, paragraphs, and full sentences.

  Recently, the use of the Internet has become universal, and various information can be acquired through the Internet. Businesses that provide Internet services through websites offer a variety of services to meet the needs of the increasingly diverse users, and the types of such services are increasing.

  Internet users interact with the services provided by such vendors in various ways. In particular, various Internet contents such as news information, dictionary information, full-text information, regional information, and shopping information are obtained through a website.

  When such a user performs a search through a website in order to obtain the content he / she desires, and through this, he / she obtains the desired content from a specific web page, the relevant mainly composed of text It is common to decipher content with the naked eye. However, from the user's point of view, it is not so preferable in recent years called the multimedia era to use only the contents provided in the text center. Realistically, as the amount of information contained in a web page increases, users must read the text with their naked eyes to decipher the content provided in the form of text. There is also a problem that you must keep an eye on the display means such as monitors. Some users have the so-called multitasking needs to perform other tasks while obtaining the desired information through the content. However, there are aspects where such needs are difficult to be met. It was.

  On the other hand, recently, it is also true that CTI (Computer Telephony Integration) technologies such as VoIP (Voice over Internet Protocol) technology, speech recognition technology, speech conversion technology, speech synthesis technology, and automatic response system have attracted much interest. In addition, even in the Internet environment in such a technology, it is possible to enjoy an advanced Internet service in which a user gives an instruction by voice, receives information by voice, and communicates by voice.

  Thus, while solving the problem in providing text-centric contents, TTS (Text To Speech) technology has been developed to be widely used in CTI technology. The TTS technology is a technology that is used more widely than the speech recognition technology, and is a human interface technology that converts various text information into speech and provides it. The TTS technology for web pages is realized mainly by extracting the text of the web page and converting it into speech and providing it to the user. For example, a word corresponding to the current position of the mouse pointer due to a mouse-over event (an action of moving the mouse) that occurs when the user pauses the mouse at a certain position on the web page for a certain period of time. Can be extracted and converted to speech, or the user can drag a certain part (region) of text on a web page and convert it to speech.

  However, the currently realized TTS service through a web page is not a perfect human interface technology. Specifically, the current TTS service converts only the word at the position recognized by the user's mouse-over operation into speech, or specifies text that the user wants to convert by dragging the mouse. There was only a problem. In the former case, unlike the user's intention, there is a problem that only the word over which the mouse is uniformly over is converted into speech. In the latter case, in order to convert the text in the range desired by the user into speech, the user must roughly decode the text with the naked eye and then specify the range of text to be converted into speech. As a result, it will be out of the spirit of the TTS technology that tries to eliminate as much as possible the case where the user is forced to decipher the text. Furthermore, the act of specifying such text is an additional time-consuming problem. there were.

Therefore, by extracting text in a specific range (for example, word, sentence, paragraph or full text range) according to the characteristics of the web page according to the user's intention and providing various text-based services, the user can There is a need for an approach to increase the convenience (convenience).

Text Extraction and Speech Conversion FIG. 3 is a flowchart illustrating a process of extracting text and converting the extracted text into speech in an embodiment of the present invention. Hereinafter, with reference to FIGS. 2A and 2B and FIG. 3, a process of extracting text in a web page and a process of outputting the extracted text by voice conversion according to an embodiment of the present invention will be described in detail. .

  When a user uses a user computer 100 to execute a web browser, in one embodiment of the present invention, a program for extracting text and converting the extracted text into speech is output together. . As described above, this program can be recorded in the program storage unit 150 included in the user computer 100, or can be recorded in another recording medium.

  Thereafter, the user can connect to the Internet and access a web page having a predetermined URL through a web browser. On the other hand, many servers provide content accessible through a web browser, but URLs are usually used to display these addresses. Such a URL is for specifying the address of a file in each server on the Internet. However, since the URL has an attribute that is determined relatively freely, other information for indicating the characteristics of the web page is used. (For example, information regarding a text extraction range according to an embodiment of the present invention) may also be included. In any case, the URL or a part of the URL can correspond to the information regarding the text extraction range according to the present invention.

  In the example of FIG. 3, a process of extracting text from a web page and outputting data obtained by voice conversion of the text in one embodiment of the present invention will be described.

  First, when the user positions the mouse pointer on the text included in the web page displayed by the web browser of the user computer 100, the mouse over recognition unit 111 of the calculation unit 110 displays the mouse over event in step S310. It is grasped (determined) whether or not an error has occurred.

  In step S330, the extraction range information confirmation unit 112 determines whether or not the text extraction range information database 130 has information regarding the text extraction range stored corresponding to the URL of the current web page. As described briefly above, the text extraction range information database 130 stores information on the text extraction range corresponding to the URL of the web page. Such information regarding the text extraction range can be stored for each URL, and can also be stored collectively for each type of the web page. This will be described in more detail below.

  In step S330, when the extraction range information confirmation unit 112 determines that the information regarding the text extraction range corresponding to the URL of the current web page does not exist in the text extraction range information database 130, in step S331, the extraction range The information request unit 113 requests the TTS server 300 for information regarding the text extraction range corresponding to the URL of the current web page. According to an embodiment of the present invention, the latest extraction range information database 500 referred to by the TTS server 300 includes various information required for providing the TTS service, that is, information on the text extraction range of each URL, and Information on the types of web pages provided for each URL is periodically updated to store the latest information on the text extraction range. When the extraction range information request unit 113 requests information regarding the text extraction range corresponding to the URL of the current web page, the latest extraction range information acquisition unit 330 of the TTS server 300 refers to the latest extraction range information database 500. Then, the latest information corresponding to the corresponding URL is transmitted to the calculation unit 110 of the user computer 100.

  In step S330, if the extraction range information confirmation unit 112 determines that the information regarding the text extraction range corresponding to the URL exists in the text extraction range information database 130, the latest extraction range information of the calculation unit 110 in step S333. Since the request unit 115 determines whether or not the information existing in the text extraction range information database 130 is the latest information, the request unit 115 receives the provision of the latest information from the TTS server 300 if the information is not the latest information. Is transmitted to the TTS server 300. The latest extraction range information determination unit 310 of the TTS server 300 exists in the text extraction range information database 130 with reference to information stored in the latest extraction range information database 500 in response to a request from the latest extraction range information request unit 115. It is determined whether the information to be updated is the latest information. At this time, for example, if the information is the latest information, a predetermined signal corresponding to the information is transmitted to the user computer 100. On the other hand, for example, when the information is not the latest information, the latest extraction range information acquisition unit 330 extracts the latest text extraction range information stored in the latest extraction range information database 500 and calculates the calculation unit of the user computer 100. 110 can be transmitted.

  In step S340, the calculation unit 110 receives information regarding the text extraction range transmitted by the TTS server 300 in response to the request issued in step S331 or step S333. That is, the calculation unit 110 extracts only the word at the position where the mouse is over, or extracts a sentence or a paragraph from the text of the web page currently displayed on the web browser, or is included in the web page. Receive information about whether to extract full text. In the latest extraction range information database 500 referred to by the TTS server 300, the latest information regarding the text extraction range is updated and stored for each URL. Therefore, in step S340, the information regarding the text extraction range received from the TTS server 300 is stored. Is always the latest information.

  In addition, the calculation unit 110 stores the latest information regarding the text extraction range received from the TTS server 300 in the text extraction range information database 130. If the information regarding the text extraction range of the current web page exists in the text extraction range information database 130, but the TTS server 300 determines that the information is not the latest information, it is stored in the text extraction range information database 130. Information is updated to the latest information transmitted by the TTS server 300; otherwise, such an update can be omitted. On the other hand, if the determination result in step S330 is “No”, the received latest text extraction range information is newly stored in the text extraction range information database 130.

  In step S350, based on the text extraction range information received from the TTS server 300 or the latest text extraction range information stored in the text extraction range information database 130, a word, sentence, paragraph or whole sentence is extracted. The required extraction scheme can be determined. An example regarding the text extraction method according to the present invention will be described later.

  In step S360, text is extracted based on the text extraction range and text extraction method determined in the preceding step. At this time, the extracted range of text can be visually distinguished from other text that is not extracted. Therefore, the user can grasp which part of the text of the web page has been extracted, thereby indirectly checking what characteristics the web page has. can do. Furthermore, when it is determined that the web page and the corresponding text extraction range are not appropriate, the user can provide this to the TTS server 300 as user feedback.

  In step S370, the text extracted in step S360 is transmitted to the TTS server 300. The TTS conversion unit 370 of the TTS server 300 converts the received text into speech data by referring to the speech conversion database 700 storing information necessary for converting the text into speech, and further converts this into speech data. 100 can be transmitted. In the voice conversion database 700, voice data can be stored for each encoded text, and corresponding voice data can be stored for each word, each sentence, or each paragraph.

  In step S380, the audio data transmitted from the TTS server 300 is transmitted to the user computer 100.

  In step S390, the received audio data is provided by the audio data providing unit 119 of the computing unit 110, and the audio data can be output from the output unit 180 such as a speaker.

  In the present specification, in one embodiment of the present invention, the user computer 100 has a text extraction range information database 130 different from the TTS server 300, and is basically based on the text extraction range information stored in the database. However, the reference database for deciding which range of text to extract is centralized in the latest extraction range information database 500 while omitting such components. It is also possible to understand that, unlike the case where the voice conversion is described as an example, it can also be performed by the user computer 100 without referring to the voice conversion database 700 by the TTS server 300. There must be. On the other hand, in the modification according to the present invention, it should be understood that the so-called text extraction referred to in the present invention can be performed not only by the user computer 100 but also by the TTS server 300 as an alternative. Don't be.

Utilization of Information on Text Extraction Range According to an embodiment of the present invention, it is possible to extract and use text in a different range based on the characteristics of a web page. Below, the example of the characteristic of the web page which is a reference | standard for differentiating the range of text extraction is demonstrated.

  Each web page that a user accesses using the user computer 100 has a unique URL, and each web page has certain characteristics. Such web pages can be classified into various categories such as news article pages, life information pages, shopping information pages, encyclopedia pages, language dictionary pages, full text information pages, blog pages, etc. according to the content attributes. . In the unlikely event that the content contained in a web page is a news article, the user viewing the web page will not be able to concentrate on a specific word or sentence, but rather the full text of the news article or the contents of a given paragraph. Should try to figure out. On the other hand, if a user views a web page that deals with full-text information such as the “knowledge iN” corner, which is the applicant's famous knowledge service, he / she should be interested only in knowledge questions and the contents of answers related to them. It is. In addition, a user who is viewing a web page of an encyclopedia or a language dictionary is likely to be interested only in the definition of a specific word and an example sentence for explaining the definition. Therefore, the text extraction range that is the basis for providing a text-based service must be changed according to the attributes and types of content included in the web page. That is, for example, for a web page containing a news article, it is preferable to extract the text in the page in paragraphs or full text units, and for a dictionary page, it corresponds to a word and its associated description. It would be preferable to extract only the text you want.

  For this reason, the text extraction range information database 130 according to an embodiment of the present invention may store information regarding different text extraction ranges based on the characteristics of each web page. In the text extraction range information database 130 according to the present invention, a URL of a web page or the like can be stored corresponding to information on the text extraction range.

  If necessary, information in the extraction range information database 130 can be changed or deleted according to a user's online / offline request. It should be noted that only the trader providing the TTS service should have the authority to access the information in the extraction range information database 130. As described above, the information in the extraction range information database 130 can be updated to the latest information through communication with the TTS server 300. To this end, the TTS server 300 may be configured to include the extraction range information database 130, or may be configured to use the latest extraction range information database 500 that communicates with the TTS server 300.

Acquisition of information regarding latest extraction range The extraction range information confirmation unit 112 of the calculation unit 110 according to an embodiment of the present invention confirms whether or not there is information regarding the text extraction range, and based on the result, updates the latest information from the TTS server 300. The process of acquiring information related to the extraction range will be described in detail.

  As described above, the extraction range information confirmation unit 112 confirms whether or not the information regarding the text extraction range corresponding to the current web page exists in the text extraction range information database 130 of the user computer 100.

  For example, when it is determined that there is no information regarding the text extraction range corresponding to the URL of the current web page in the text extraction range information database 130, the extraction range information request unit 113 of the calculation unit 110 sends the information to the TTS server 300. Request information about the text extraction range.

  Accordingly, the latest extraction range information acquisition unit 330 of the TTS server 300 acquires information on the text extraction range requested from the extraction range information request unit 113 with reference to the latest extraction range information database 500, and uses this information as the user computer 100. To the arithmetic unit 110. The calculation unit 110 receives information about the text extraction range, stores it in the text extraction range information database 130, and extracts the text of the current web page based on the information.

  On the other hand, according to one embodiment of the present invention, if the extraction range information confirmation unit 112 determines that the information related to the text extraction range corresponding to the current web page already exists in the text extraction range information database 130, The latest extraction range information request unit 115 of the unit 110 can request the TTS server 300 to determine whether or not the corresponding information is the latest information.

  Subsequently, the latest extraction range information determination unit 310 of the TTS server 300 refers to the latest extraction range information database 500 to determine whether or not the information regarding the text extraction range existing in the current text extraction range information database 130 is the latest information. Can be determined.

  If the information existing in the text extraction range information database 130 and the information existing in the latest extraction range information database 500 are the same, the TTS server 300 sends the information in the text extraction range information database 130 to the calculation unit 110 of the user computer 100. It is possible to transmit a predetermined signal for confirming that is the latest information.

  Further, for example, when it is determined that the information existing in the text extraction range information database 130 and the information existing in the latest extraction range information database 500 are different, the TTS server 300 receives information existing in the latest extraction range information database 500. Can be transmitted to the calculation unit 110 of the user computer 100. Accordingly, the calculation unit 110 can replace the information stored in the text extraction range information database 130 with the received information.

Text Extraction Method According to an embodiment of the present invention , in extracting text included in a web page in units of words, sentences, paragraphs or whole sentences, MSAA (MicroSoft Active Accessibility) method or IHTML (Inner HTML) is used. This method can be used for extraction. According to an embodiment of the present invention, the decision on the extraction method is also determined based on the characteristics of the web page if necessary. Here, the MSAA method is a method of extracting a predetermined range of text in a web page using a predetermined function provided with a commonly used Internet Explorer (registered trademark) web browser. The method is a method of extracting text in tag units from a web page created in the HTML format (for example, a method of extracting text between predetermined tags). The determination of the text extraction method according to the present invention can be performed by an extraction method determination unit 117 as shown in FIG. 2A.

  For example, assume that a user is accessing a web page created with the following HTML source.

<Div class = 'knCnt' style = 'overflow: hidden; word-wrap: break-word; word-break: break-all;'>
<P> Mathematics &nbsp; is closely related to science and is an important discipline that is needed in many disciplines </ P>
<P> Why is there no Nobel Prize? </ P>
<P> Please write in detail for the Fields Prize </ P>
<P> Mathematical Nobel Prize. . . </ P>
</ Div>

  When the mouse over recognition unit 111 of the arithmetic unit 110 recognizes that the mouse over event has occurred in the “family” position among “close to science”, according to the MSAA method, “Mathematics is closely related to science and is an important discipline that is needed in many disciplines,” which is the text between close tags (ie, <P> and </ P> in the example sentence) Can be extracted. On the other hand, according to the IHTML method, text can be extracted in units of <P> HTML tags, but all HTML documents are brought and text is extracted based on <div> tags. It is also possible. In this way, if text is extracted based on the <div> tag, the entire text is extracted.
