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

FIG. 1 is a diagram showing a configuration of an online content value enhancement system (hereinafter abbreviated as "online content value enhancement system") using search engine optimization according to a preferred embodiment of the present invention. (Hereinafter abbreviated as " method for enhancing an online content value ") using search engine optimization according to a preferred embodiment of the present invention.

Referring to FIG. 1, an online content value enhancement system according to a preferred embodiment of the present invention includes an indexing unit 110, a keyword extracting unit 120, a site map generating unit 130, an indexing monitoring unit 140, (150).

Referring to FIG. 2, the function of each component will be described. First, the indexing unit 110 receives contents from a plurality of websites (S210).

There are no restrictions on multiple websites, as long as they are capable of providing content through the Internet, such as a general online shopping mall, a news web site providing news articles, an internet portal site, a personal blog site, or a community web site for individuals.

In addition, the content may be a content composed of only simple text, an image, or a moving image, or may include text and an image, text and a moving image, or both.

The indexing unit 110 performs indexing on the received content, generates content indexing data, and outputs the content indexing data to the keyword extracting unit 120 (S220).

3 is a diagram illustrating an example of indexing data generated by the indexing unit 110 according to a preferred embodiment of the present invention. As shown in FIG. 3, the indexing data of the present invention can be used for various purposes such as a content title, a content creation date, a content author, a content content, a content publishing URL, a content publishing web site name or institution, Lt; / RTI > information.

The indexing data shown in FIG. 3 includes the content title (where the father is the mother, the reason why the children are pretty because of the mother gene), the date (2013-02-25), author (Kookmin Ilbo cookie news team) ), A URL (http://news.kukinews.com/article/view-), an agency (Kookmin Daily), a category (entertainment), and a keyword (where is Daddy).

The keyword extracting unit 120 extracts a main keyword from the indexing data input from the indexing unit 110, further extracts the keyword as a commercial keyword using the main keyword, summarizes the main text, And outputs the content summary to the site map generating unit 130 (S230).

The keyword extracting unit 120 extracts the main keywords by assigning the scores differentially according to the following five conditions to the respective words extracted from the indexing data according to the morphological analysis algorithm.

The first condition grades the words differently depending on whether the words were extracted from the title or from the text. Generally speaking, the words in the title are more likely to be the main keywords, so the words extracted from the title are given higher scores than the words extracted from the text.

The second condition is to score a word at a position adjacent to the word when a word extracted from the title is found in the text or when a word extracted from the title is found in the text. In this case, the former can be given a higher score.

In the case of FIG. 3, for example, in the title of the article ['Where are my dad' and 'Why are my children pretty thanks to my mother's genes'], words such as dad, where, mama, . In addition, words adjacent to the main keywords extracted from the titles in the article content are sequentially searched and scores are given. In the example of Fig. 3, the process of finding the adjacent word of the keyword " mom " will be described. In the text of the present invention, several recent photographs have been uploaded under the heading ' , A search target keyword " mother " is found, and a predetermined number of adjacent words (e.g., two words) are searched for " mom " In this case, the phrase "Daddy is under the title of moms mimo" is extracted, and the words "dad", "somewhere" and "mom" in the two words preceding "mom" "And" title "are extracted and given a score.

The third condition grades according to the position in the text where the word exists. Depending on where the word is located within the text (less than the top 25% of the document size), mainte- nance (greater than 25% of the document size and less than 75%), and conclusion (over 75% of the document size) . In the preferred embodiment of the present invention, a higher score is given to the keyword located at the conclusion, but this can be adjusted according to the manner of development of the content. For example, in the case of a bold sentence, a higher score can be assigned to a word located in the introductory part.

The fourth condition is weighted according to the word frequency. The more frequent repetition of a word, the more important it is because it can be a high score, but if the frequency of a certain number of words more than a certain number of words, the content is rather a spam document is likely to give a reverse weight.

The fifth condition is that there exist a set of main keywords pre-classified as the main keywords of the category to which the content belongs, and in the case of the corresponding words or in the same word as the main keywords of other documents analyzed before the same date of the same category Score is given.

When the main keyword is extracted from the main content, the keyword extracting unit 120 further extracts the commercial keyword using the extracted main keyword. The commercial keyword may be determined as a parent concept of the extracted key keyword or a word that is closely related to the extracted keyword so that the content can be searched not only in the main keyword but also in the search process of the commercial keyword, To be included in the content.

For example, when the main keywords such as "Lee Hyori", "sexy", and "dance" are extracted as the main keywords, the keyword extracting unit 120 can extract "diet" as commercial keywords from the main keywords. In this case, the content may include diet product advertisements, and may be exposed not only to users who search Lee Hyori, sexy, and dance, but also to users who search for diets.

In addition, when the keywords "Thailand" and "low cost airline" are extracted as the main keywords, commercial keywords such as "travel" and "Thailand hotel" can be extracted. However, &Quot; and " fall " are extracted together, words having a negative image of " falling " may be filtered so that the corresponding content is not included in the advertisement corresponding to the commercial keyword.

The site map generating unit 130 generates a site map using the indexing data input from the indexing unit 110, the main keyword input from the keyword extracting unit 120, and the commercial keyword (S240) The site map is provided to a plurality of search engines (S250).

4A and 4B are views showing an example of a site map according to a preferred embodiment of the present invention. FIG. 4A shows a site map for contents provided by a general site, and FIG. 4B shows a site map for news contents.

The site map itself may be generated according to internationally standardized forms.

The indexing monitoring unit 140 notifies the site map generating unit 130 of the fact that the site map of the specific content is provided to the search engines and transmits the main keyword received from the site map generating unit 130 or the keyword extracting unit 120 And searches the plurality of search engines provided with the site map at a predetermined time period using the commercial keywords to search the search order of the contents and outputs the search result to the analyzer 150 at step S260.

The analysis unit 150 analyzes the access ranking of the traffic caused in the search ranking and the web site, and analyzes the advertisement effect and the profitability according to the traffic (S270).

For example, the analysis unit 150 may analyze the traffic inducing efficiency by analyzing the traffic inducement level against the search ranking of the corresponding main keyword or commercial keyword included in the site map. In addition, the analyzer 150 may analyze each traffic connection log to determine which search engine has accessed the corresponding website through each traffic. After the connection, It is possible to investigate and analyze which advertisement is selected.

Particularly, in the process of analyzing the advertisement, the analyzer 150 can analyze the position (top advertisement, bottom advertisement, side advertisement, etc.) of the advertisement selected by the user, the form of the advertisement (batting advertisement, , Which can be used to analyze the profitability of advertising.

In addition, the analyzer 150 may analyze not only a specific content but also a plurality of contents generated from the corresponding web site.

In particular, the analysis unit 150 analyzes the amount of traffic generated for each of the plurality of contents generated on the corresponding web site, and the advertisement effect for each content, and analyzes whether the kind of the content is attracted to the public And the profit per content can be confirmed through the revenue analysis of the circulated contents and reflected in the budget for the content production (S280).
