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

1 is a schematic block diagram of a system for providing up-to-date information according to an embodiment of the present invention.

As shown in FIG. 1, the latest information providing system 10 according to an exemplary embodiment of the present invention includes a web page extractor 12, a webpage storage unit 14, a main word extractor 16, and a counter 18. ), A main word storage unit 20, a determination unit 22, and an information providing unit 24.

The web page extracting unit 12 extracts a predetermined web page from respective websites included in the website list for each subject. At this time, the list of websites for each topic may be extracted from directory information provided by various portal sites. For example, as shown in FIG. 2A, a list of websites as shown in FIG. 2B is extracted from directory information. 2b shows a list of websites on the subject of 'movie'.

In one embodiment, the web page extraction unit 12 extracts the first page of each website included in the website list for each subject. This is because the first page of each website often contains new information or updated information of the content. In the modified embodiment, not only the first web page of the website but also a web page providing new information may be extracted.

The web page extracting unit 12 extracts the above-mentioned web page from the website in predetermined cycle units, and the predetermined cycle is preferably set to one day.

The web page storage unit 14 stores web pages extracted by the web page extraction unit 12 for each field. In the case of web pages stored in the web page storage unit 14, after the main word included in the web page is counted by the counter 18, the web pages may be deleted to efficiently use the storage space.

The main word extractor 16 extracts one or more main words from the web page extracted by the web page extractor 12. In one embodiment, the main word extraction unit 16 extracts a main word from the anchor text included in each web page. The anchor text refers to a clickable portion of a specific web page. The anchor text is a word representing the linked document, such as the title of the linked document. The main word extractor 16 extracts each main word from all anchor texts included in each web page.

In one embodiment, the main word extractor 16 extracts a noun or a compound noun included in the anchor text as the main word in extracting the main word from the anchor text of the web page. In this case, all nouns or compound nouns included in the anchor text may be extracted as the subject words, but anchor texts of only the extracted nouns or compound nouns may be excluded from the main word.

For example, if there is an anchor text "How did you see the colorful vacation?" Among web pages related to the movie, the compound noun "gorgeous vacation" is extracted from the anchor text as the subject. As another example, when there is an anchor text of "the gravestone seems to smoke after seeing the colorful holiday", nouns or compound nouns such as "gorgeous holiday", "myo", "song" are extracted from the anchor text, If an anchor text with the word "gorgeous holiday" exists on the web page or another web page, but no anchor text with the words "myo" and "spinning" does not exist, "gorgeous holiday" is the subject of the anchor text. Will be extracted.

Meanwhile, in the case of a link having no anchor text, such as a link formed as an image, the main word may be extracted from the title of the web page. At this time, the title of the web page may be obtained by downloading the web page itself.

The counter 18 counts the number of occurrences of the main words extracted by the main word extracting unit 16 and stores them in the main word storage unit 20 for each main word. In one embodiment, the counter 18 counts the number of occurrences of the main words extracted from each web page extracted for a specific subject according to the period in which the web pages are extracted and stores the result in the main word storage 18. Can be.

For example, if it is set to extract a web page from the website list on a daily basis, and the theme of the website list is a movie, the number of occurrences of the main words of each web page extracted on the theme "movie" on August 1, 2007 Counting and storing each key word, and counting the number of occurrences of each key word of the web page extracted on August 2, 2007 to store each key word.

The main word storage unit 20 stores the main word extracted by the main word extracting unit 16 together with the occurrence number of each main word calculated by the counter 18 and the anchor text including the main word. In one embodiment, in storing the extracted main word, the main word storage unit 20 may store a URL (Uniform Resource Locator) address mapped to the anchor text including the extracted main word along with the main word.

A format in which the above-described data is stored in the main control unit 20 will be described with reference to FIG. 3. As shown, the above-described data is recorded in the main word storage unit 20 in the form of a table. The main word field 26 stores the main words extracted from each web page, and the anchor text field 28 includes the main word. The anchor text is stored, and the URL field 30 stores the URL address linked to the anchor text. In addition, the counting date field 32 stores the date on which the corresponding main word is counted, and the appearance frequency field 34 stores the number of occurrences of the extracted main word.

Referring back to FIG. 1, the determination unit 22 compares the number of occurrences of the main word extracted by the main word extraction unit 16 at predetermined intervals to determine the amount of change in the number of occurrences of each main word and use the amount of change in the number of occurrences. The main words are classified as first type main words or second type main words. In detail, the determination unit 22 classifies the corresponding main word as the first type main word when the amount of change in the appearance frequency of the main word is equal to or greater than the first reference value.

Here, the change in the number of appearances is more than the first reference value means that the recent number of appearances increases or decreases compared to the previous appearances, and that the increase in the number of appearances includes content related to the relevant keyword recently. This means that the subject can be judged to represent the latest information. For example, when a movie is released, many websites include a topic related to the movie that has not appeared before due to a review of the movie or an interview with a main actor before the release.

In addition, the decrease in the number of occurrences was a topic that had been dealt with by many websites until recently, but its content has been greatly reduced, and it is determined that this topic is not a problem for people anymore. If registered, you can delete the subjects.

Meanwhile, although the number of appearances is large, it is always included in all web pages so that the main words such as menus can be excluded from the latest information through the above-described process since there is almost no change in the appearance frequency compared to the previous. For example, in a movie-related website, the term "pre-sale" is always included in the website, so the number of occurrences may be high, but the change in the number of appearances is less than the first reference value and thus excluded from the latest information.

Meanwhile, the determination unit 22 classifies the corresponding main word as the second type main word when the amount of change in the number of occurrences of the main word is more than the second reference value and less than the third reference value. Specifically, the main word, which is the latest information but does not change much in the number of occurrences, is classified as the second type main word. That is, the second reference value serves as a criterion for determining whether the corresponding main word is new information, and the third reference value serves as a criterion for determining whether the corresponding main word is a reason for reason. In this case, the third reference value may be set to be the same as the first reference value, but may be set to be less than the first reference value.

For example, when food information is updated on a cooking-related website, the updated food information is new information because it has not appeared before but recently appeared, but since it is not an issue for people, the change in the number of appearances is not large. It is classified as a type subject.

In one embodiment, the determination unit 22 may determine the amount of change in the appearance frequency of each main word every 1 day, 7 days, or 10 days.

The information providing unit 22 provides the first type main word and the second type main word classified by the determination unit 20 to the user for each type together with the contents including the corresponding main word. Specifically, the main words classified as the first type are provided to the user by grouping the first types, and the main words classified as the second type are provided to the user by grouping the second types. In this case, the information providing unit 22 preferably provides anchor text including the corresponding main word as the content including the corresponding main word. This allows the user to view the web page linked with the anchor text by clicking on the anchor text.

In one embodiment, the information providing unit 22, in providing the first type or the second type main word to the user, creates a directory for each subject and corresponds to the directory of the subject to which the first type or the second type main word belongs. You can provide up-to-date information by listing topics. For example, when the first type or the second type main word is related to a movie, the first type or the second type main word is arranged in a keyword form in the movie area of the generated directory. In the modified embodiment, the first type or the second type main word may be provided to the user in a region to which the corresponding main word belongs among the directories provided in each portal site without creating a separate directory.

In another embodiment, the first type or the second type main word may be provided through the search result. For example, when a first type subject is input as a search query, the anchor text stored together with the first type subject is provided to the user as a search result.

A method of providing the latest information to the user through the above-described latest information providing system will be described in detail with reference to FIG. 4.

First, a predetermined web page is extracted and stored from each website included in a website list on a specific topic (step 100). At this time, the list of websites for each topic may be extracted from directory information provided by various portal sites. In one embodiment, in extracting a web page from each website included in the website list for each subject, the first page of each website is extracted. This is because the first page of each website often contains new information or updated information of the content. In the modified embodiment, not only the first web page of the website but also a web page providing new information may be extracted.

Next, at least one topic word is extracted from the extracted web page and stored (step 110). In an embodiment, in extracting a main word from a web page, the main word may be extracted from anchor text included in each web page. To do this, we first extract all anchor text from each web page, and then extract each main word from all extracted anchor text.

In extracting the main word from the anchor text of the web page, a noun or compound noun included in the anchor text may be extracted as the main word. In this case, all nouns or compound nouns included in the anchor text may be extracted as the main word. It is preferable to exclude from the main word that the noun or compound noun anchor text of the noun or compound noun does not exist in the web page or other web pages.

The extracted subject word is saved along with the anchor text containing the subject word and the URL address linked with the anchor text.

Thereafter, the number of occurrences of the extracted main word is counted and the result is stored for each main word (step 130), and the above-described steps 100 to 130 are repeated for each predetermined period (step 140). For example, when a predetermined period is one day, the process of extracting a predetermined web page from the website list, extracting a main word from the extracted web page, and counting the number of occurrences of the extracted main word is repeated every day.

Next, the amount of change in the number of occurrences of each main word is determined by comparing the number of occurrences of the extracted main word every predetermined period (step 150). In one embodiment, the amount of change in the number of occurrences of each main word may be determined based on one day, seven days, or ten days.

As a result of the determination, when the amount of change in the appearance frequency is equal to or greater than the first reference value, the corresponding main word is classified into the first type main word (step 160). Changes in the number of occurrences above the first threshold means that the number of recent occurrences has increased or decreased compared to the number of previous occurrences. The increase in the number of appearances indicates that many websites have recently been related to the topic. As such, it can be determined that such a subject word represents the latest information.

In addition, the decrease in the number of occurrences was a topic that had been dealt with by many websites until recently, but its contents have been greatly reduced, and it is no longer an issue for people. If the main word is registered with the latest information, it is preferable to delete it.

In operation 150, when the amount of change in the appearance frequency is greater than or equal to the second reference value and less than the third reference value, the corresponding main word is classified into the second type main word (step 170). Although this type of main word is new information, it can be judged as a main word that is not being socially issued due to the small amount of change in the appearance frequency.

Finally, the first type main word or the second type main word is provided to the user for each type along with the contents including the corresponding main word (step 180). Specifically, the main words classified as the first type are provided to the user by grouping the first types, and the main words classified as the second type are provided to the user by grouping the second types.

In this case, it is preferable to provide anchor text including the corresponding main word as the content including the corresponding main word. This allows the user to view the web page linked with the anchor text by clicking on the anchor text.

In one embodiment, in providing a user with a first type or a second type main word, a directory for each subject is created and a first type or second type main word is included in a directory of a subject to which the first type or second type main word belongs. May be provided by listing, or anchor text including a first type or a second type main word may be provided through a search result.

The above-described latest information providing method may also be implemented in the form of a program that can be performed using various computer means. In this case, the program for performing the latest information providing method may be a hard disk, a CD-ROM, a DVD, a ROM. Data is stored in a computer-readable recording medium, such as, RAM, or flash memory.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features.

Therefore, it is to be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention. do.
