Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a program-equipped Web-compatible electronic device such as a PDA, a mobile phone, a television set, and a disk-mounted video recorder, a method for browsing and displaying Web contents, and a program.
[0002]
[Prior art]
Generally, the man-machine interface of a Web-compatible electronic device that incorporates a program, such as a PDA (Personal Digital (Data) Assistants), a mobile phone, a television set, and a disk-mounted video recorder, is poorer than that of a personal computer. I have to say that. On the other hand, contents on the Web are often created on the assumption that they are browsed and displayed by a mouse, a full-key layout keyboard or a similar keyboard, or a personal computer using a high-resolution display device. When browsing and displaying contents on the Web with the Web-compatible electronic device as described above, the user cannot avoid passing through various troubles.
[0003]
For example, many Web-compatible electronic devices are designed to operate a simple keyboard with a significantly reduced number of keys from a full-key layout keyboard with a finger or a pen to input a URL, which is inferior in key input operability. Do not distort.
[0004]
In most cases, a display device of a Web-compatible electronic device having a lower resolution than that of a personal computer is used. As described above, most of the contents on the Web are created on the assumption that the contents are browsed and displayed on a high-resolution display device used in a personal computer. Therefore, for example, as shown in FIG. In a display device with a low resolution provided in the compatible electronic device 161, in many cases, only a small portion 163 of the entire Web page 162 can be displayed once, and in order to see the entire page, vertical and horizontal scroll operations must be repeated. The operation is troublesome for the user.
[0005]
Further, the problem is not limited to the Web-compatible electronic apparatus, but some Web pages have a large overall data capacity due to the addition of bitmap data, animation data, and audio data. When an attempt is made to browse a Web page having a large data capacity in this way, it takes a long time to download the page in a communication environment similar to an analog connection.
[0006]
As a method of solving such a problem, a Web page desired by the user is collected on behalf of the user's browser based on instruction information from the user (browser), and text from the collected Web page is prioritized within the limited capacity. There is a known technique of installing a hypertext collection device on the Web that extracts text data within a time limit and returns the extracted text data to one file data to a user (browser) (for example, see Patent Document 1). .
[0007]

[0008]
[Problems to be solved by the invention]
However, such a known technique requires input of various instruction information such as a URL for designating a Web page desired by a user, and is not suitable for a Web-compatible electronic device apparatus having poor key input operability. Further, in the above-described known technology, in order to collect contents of many different Web sites, the user has to specify URLs corresponding to the number of the Web sites to the hypertext collection device, and the URL input operation requires I can imagine that it will take a lot of time. Further, the above-described known technique is only for collecting text data in a plurality of Web pages and providing the text data to a user.
[0009]
In view of such circumstances, the present invention provides a Web-enabled electronic device, a Web content browsing and displaying method, and a program that can comfortably browse and display contents of a large number of Web sites without inputting a URL or the like by a user. It is intended to provide.
[0010]
It is another object of the present invention to provide a Web-enabled electronic device, a Web content browsing / displaying method, and a program that allow a user to quickly access a Web page desired by a user based on a keyword.
[0011]
Still another object of the present invention is to provide a Web-enabled electronic device, a Web content browsing and displaying method, and a program that can simultaneously browse and display a plurality of headlines including a common keyword.
[0012]
A further object of the present invention is to provide a Web-enabled electronic device, a Web content browsing and displaying method, and a program, which are capable of browsing and displaying a plurality of Web pages offline without input operation of a URL or the like by a user. And

FIG. 3 is a diagram showing a module configuration of the page patrol / reconstruction program. As shown in the figure, the page patrol / reconstruction program includes a page patrol engine 31, a headline generation engine 32, a morphological analysis engine 33, a keyword generation engine 34, and a page reconstruction engine 35.
[0043]
The page patrol engine 31 traverses a plurality of Web pages at predetermined time intervals in accordance with a list of Web page URLs, which is a description content of the page patrol list defined or created in advance.
[0044]
The headline generation engine 32 extracts the text line of the headline from the Web page being circulated by the page rotation engine 31, extracts the URL of the linked page of the headline, and extracts the text line of the headline and the URL. In a database, that is, a headline / URL database is created.
[0045]
The morphological analysis engine 33 performs a morphological analysis on a text string which is a sentence of the headline stored in the headline / URL database, divides the text string into a plurality of words, and determines the part of speech of each word. Then, a database is created by associating these words with the parts of speech, that is, a word / speech database is generated.
[0046]
The keyword generation engine 34 determines from the contents of the word / speech database that the words can be keywords, such as proper nouns, facility names, organization names, person names, names other than regular person names, prefecture names, and ward names. The determined word is determined as a keyword.
[0047]
The page rebuilding engine 35 uses the headline text string stored in the headline / URL database, the source of the linked page of the headline, and the keyword generated by the keyword generation engine 34 to generate a Web-compatible page. Rebuild pages optimized for electronic devices.
[0048]
The HTML file that is the source of the page reconstructed by the page reconstruction engine 35 is stored in the reconstructed page storage area 24 set in the main memory 2 shown in FIG.
[0049]
Next, a series of operations based on the page patrol / reconstruction program in the Web-compatible electronic device will be described with reference to a flowchart of FIG.
[0050]
It is assumed that a page patrol / reconstruction program resides in the main memory 2 and operates under the basic program.
[0051]
The page patrol engine 31 of the page patrol / reconstruction program reads URLs (Uniform Resource Locators) listed on the page patrol list one by one at predetermined time intervals (step 401) (step 401). Step 403), and accesses the Web page of the read URL (step 404).
[0052]
FIG. 5 shows an example of the page circulation list 51. The page circulation list 51 describes URLs of one or more Web pages. In the present embodiment, a list of URLs of Web pages by category such as “newspaper”, “sports / entertainment”, and “popular songs” is described in the page circulation list 51. The page circulation list 51 may be preset in the Web-enabled electronic device 100 in advance, or a list periodically distributed on the Web may be obtained.
[0053]
When the web-enabled electronic device apparatus 100 acquires the source of one Web page, the headline generation engine 32 extracts the text line of the headline from the acquired Web page source and the URL of the linked page of the headline. Is extracted (step 405).
[0054]
FIG. 6 shows an example of a Web page of a newspaper site. Here, the headline is a headline 61 such as an article displayed on, for example, a homepage 60 of a Web site, and the headline (headline 61) has a detailed article content (text string). 64) is set to a link 63 to another Web page 62.
[0055]
A specific method for extracting a headline text string from the source of a Web page is as follows. FIG. 7 shows a part 62 of the Web page 60 of FIG. 6 and an HTML source 71 corresponding thereto. The headline generation engine 32 determines, in the HTML source 71, whether or not this is a headline, with respect to the text string 72 between the <a> tag called an anchor and the </a> tag. Do it individually.
[0056]
As a specific method for determining whether or not the text string 72 sandwiched between the <a> tag and the </a> tag is a headline, the number of characters in the text string 72 is not less than a certain number. A method of determining a headline in a certain case, determining an average value of the number of characters of the text string 72 in a page, and determining whether the headline is determined according to a predetermined determination condition based on the average value. And a method of counting the number of consecutive anchor tags (the number of lines) and determining that the text string 72 surrounded by these anchor tags is a headline when the count value is equal to or greater than a certain value. is there.
[0057]
The headline generation engine 32 extracts the text line 72 of the headline from the source of the acquired Web page by the above-described method, and extracts the URL 73 of the link destination page described as the href attribute in the anchor tag. The database is created by associating the line text string 72 with the URL. That is, it is stored as a headline / URL database in the headline / URL database storage area 26 of the main memory 2 (step 406). As described above, when the reading of the URLs of all the Web pages described in the page circulation list 51 is completed (YES in step 402), the morphological analysis engine 33 is started.
[0058]
The morphological analysis engine 33 performs a morphological analysis on a text string that is a sentence of the headline stored in the headline / URL database, and divides the headline text string into a plurality of words, Is determined (step 407).
[0059]
FIG. 8 is an example of a morphological analysis of a headline sentence. As described above, the headline text string 80 is divided into a plurality of words 81 by the morphological analysis, and the part of speech 82 of each word 81 is determined. Then, the morphological analysis engine 33 associates the determined word 81 with its part of speech 82 and stores it in a database in the word / part of speech database storage area 27 of the main memory 2 (step 408).
[0060]
Next, the keyword generation engine 34 is activated. The keyword generation engine 34 determines from the content of the word / speech database that it can be a keyword, such as a proper noun, a facility name, an organization name, a person name, a name other than a regular person name, a prefecture name, or a ward name. The extracted words are extracted as keywords (step 409). In addition, in this keyword generation, an optimized keyword selection criterion is adopted so that a new word, a first name and a last name which are not in the dictionary can be detected as keywords. Specifically, for example, as shown in FIG. 9, a keyword selection criterion 91 is added so that a surname, first name, or the like that is not in the dictionary can be selected as a keyword based on the suffix “san”.
[0061]
Thereafter, the page reconstruction engine 35 is activated. The page reconstruction engine 35 uses the headline text string stored in the headline / URL database, the source of the linked page, and the keyword generated by the keyword generation engine 34 to generate the Web-compatible electronic device. A page optimized for the purpose is reconstructed (step 410).
[0062]
FIG. 10 shows an example of pages reconstructed by the page reconstruction engine 35 and their links. In this example, one or more keyword list pages 101 in which a list of keywords is described, and a list of one or more pages created for each keyword, each containing a common keyword, are described. Headline list page 102 and one or more pages created for each headline, detail page 103 comprising a main text portion in a Web page linked to each individual headline. Is done.
[0063]
Here, each of the keyword list pages 101 is created as a page linked one-to-one to each category item of the portal page 104 set corresponding to the page circulation list. The headline list page 102 is created as a page linked one-to-one to each keyword described in the keyword list page 101.
[0064]
Further, the detail page 103 extracts only a main text string excluding elements such as banners and advertisements irrelevant to the content of the headline from the source of the actual Web page to which the headline is linked. Created. As a specific method, for example, as shown in FIG. 11, in the HTML source 111 of the actual Web site 110 to which the headline is linked, a portion where the number of characters of the text enclosed between the tags is the largest in the page For example, there is a method of extracting the text string 112 of the At this time, the processing efficiency of text extraction can be improved by narrowing down the portion including the main text according to the type of tag. More specifically, as shown in FIG. 12, for example, there is a method in which the type of a tag that ignores the number of characters is determined in advance, and only the number of characters of the text surrounded by other types of tags is counted.
[0065]
The HTML source file of each page reconstructed by the page reconstruction engine 35 in this manner is stored in the reconstructed page storage area 24 of the main memory 2. The HTML source file of the reconstructed page stored in the reconstructed page storage area 24 is backed up in the non-volatile program / data storage unit 3 so that it can be used even after the system is restarted.
[0066]
Thereafter, the portal page 104 as shown in FIG. 10 is displayed on the screen of the display device 6 by activating the Web browser by the user. On the portal page 104, items indicating categories such as "newspaper", "sports / entertainment", and "popular songs" are displayed. When the user selects a desired item from the operation input unit 13, the web browser displays the item. The keyword list page 101 linked to the selected item is read from the reconstructed page storage area 24 of the main memory 2 and displayed on the screen of the display device 6.
[0067]
Next, when the user selects a desired keyword from the keyword list page 101 displayed on the screen of the display device 6, a list of headlines linked to the selected keyword is displayed by the Web browser. Is read from the reconstructed page storage area 24 of the main memory 2 and displayed on the screen of the display device 6.
[0068]
Further, when a desired headline is selected by the user from the headline list page 102 displayed on the screen of the display device 6, a detailed page 103 linked to the selected headline is displayed by the Web browser. Is read from the reconstructed page storage area 24 of the main memory 2 and displayed on the screen of the display device 6.
[0069]
In this way, browsing and display of pages optimized for the Web-enabled electronic device 100 are realized. For example, as shown in FIG. 15, even in a Web-compatible electronic device 150 such as a PDA with a low display resolution, the content provided by the Web can be browsed with high visibility.
[0070]
Further, the HTML source file of the page reconstructed for the Web-enabled electronic device 100 is stored in the Web-enabled electronic device 100 (the main memory 2 or the program / data storage unit 3). In response to a page browsing request, the internal storage unit is accessed to read the source of the corresponding page, thereby improving the average response speed of page browsing and displaying, and browsing the contents of many Web sites offline. Display can be performed.
[0071]
Further, since it is possible to select content to be browsed based on a keyword, a user can quickly access a page of content of interest to the user. In addition, headlines of a plurality of Web pages including a common keyword can be compared and viewed on one screen.
[0072]
In addition, when the page is reconstructed, unnecessary elements that are not related to the content of the headline, such as banners and advertisements, are removed, thereby shortening the time required for downloading the page from the Web and improving the display response speed. be able to.
[0073]
Further, since a key operation or the like for inputting a URL by a user becomes unnecessary, it greatly contributes to improvement of operability of a Web-compatible electronic device such as a PDA and a mobile phone.
[0074]
Specifically, the Web-enabled electronic device 100 described above is used for various types of digital home appliances such as a terminal device such as a PDA and a mobile phone, and a television set and a disk-mounted video recorder. be able to.
[0075]
Some television sets and disk-mounted video recorders have a function of making a program recording reservation using a keyword or the like input in advance by a user. Therefore, a keyword input by the user for program recording reservation is searched from the keyword list page 101 shown in FIG. 10, and for example, as shown in FIG. 13, a headline list page 102 linked to the keyword is searched. May be displayed on the screen 141 of the television 140. As a result, it is possible to provide the user with contents on the Web related to the recording reservation program.
[0076]
It should be noted that the above-described processes of page cycling, headline generation, morphological analysis, keyword generation, and page reconstruction performed by the Web-enabled electronic device 100 can be performed by a server installed on the Internet. is there. In this case, the HTML source of the reconstructed page is stored on the server side. Upon receiving the request from the Web-compatible electronic device, the server returns the stored reconstructed page.
[0077]
FIG. 14 is a diagram showing the configuration of the Web system in this case. The window server 131 and the Web-enabled electronic device 132 can be connected via the Internet 133. The contact server 131 includes a CPU 138, a main memory 134, a program / data storage unit 135, and the like.
