Hereinafter, with reference to the contents described in the accompanying drawings will be described in detail an embodiment according to the present invention. However, the present invention is not limited or limited by the embodiments. Like reference numerals in the drawings denote like elements. The method for providing a related site according to an embodiment of the present invention may be performed by a related site providing system.

1 is a flowchart illustrating a method for providing a related site according to an embodiment of the present invention.

The method of providing a related site according to an embodiment of the present invention may expose at least one search word introduced to a site (S101). For example, in the step S101 of exposing at least one search word introduced to the site, the site inflow rate for each of the at least one search word and the at least one search word may be exposed. In this case, in the step of exposing at least one search word introduced to the site (S101), the at least one search word may be arranged and exposed according to the inflow rate of each search word. In one example, the site may include a minihompy, a blog or a cafe. The type of site is not limited, and any site can be included as long as it can be accessed through a link such as a URL online.

For example, the site inflow rate for a search term may be calculated by the number of times of accessing the corresponding site and the number of accesses per search term. For example, it may be assumed that the search words a, b, and c flow into the 'A' site. At this time, the total number of times 'A' site was accessed was 100, of which 50 flowed into the query 'a', 37 flowed into the query 'b', and flowed into the query 'c'. Let's say 13 cases. Then, the site inflow rate for each search term may be calculated as 50% for search term 'a', 37% for search term 'b' and 13% for search term 'c'. In operation S101, at least one search word introduced to a site may be exposed in a sorted order of 'a', 'b', and 'c' according to the site inflow rate.

In the method of providing a related site according to an embodiment of the present invention, when any one of the at least one search term is selected, the related site for the search term may be detected (S102). Referring to the above example, when the user selects the 'b' search word, detecting the related site for the search word (S102) may detect the related site for the 'b' search word.

More specifically, if the search query 'Jazz' is ranked as the top search term inflow for the 'abcde' blog, and the user selects 'Jazz', the relevant site is provided by the blog, cafe or mini associated with 'Jazz'. Related sites such as homepages can be detected and provided. That is, the method for providing a related site according to an embodiment of the present invention may provide a related site associated with a specific search word.

In one example, detecting the associated site for the search word (S102) may collect the site to determine at least one characteristic word for the collected site. At this time, the step (S102) of detecting a related site for a search word may collect all the ranges of sites that can be collected and store them in a database. In operation S102, detecting an associated site for a search word may determine at least one characteristic word for a site stored in a database. In this case, the characteristic word may be a word representing a representative characteristic of the corresponding site. However, when various kinds of articles are posted through a plurality of lists in the site, the characteristic word may be one or more.

In this case, the determining of the at least one characteristic word may determine the at least one search word introduced to access the document of the site as the characteristic word of the site. For example, the at least one search word introduced to access the document of the site may be determined through the search log data accumulated during the preset period.

In the determining of the at least one characteristic word, the at least one index word for the document included in the site may be determined as the characteristic word of the site. That is, the index word that can represent the characteristics of the documents included in the collected site may be determined as the characteristic words of the site. For example, in the case of a blog related to 'wine', a document included in the blog may include content related to 'wine' and an index word may be a word related to 'wine'.

At this time, when a word that is frequently exposed or a word that is rarely exposed to the entire document of the site becomes an index word, the index word may not efficiently reflect the characteristics of the site. Accordingly, in the determining of the at least one characteristic word, the index word belonging to a preset document exposure frequency range among the at least one index word may be determined as the characteristic word of the site.

In the determining of the at least one characteristic word, the at least one tag word input when a document included in the site may be determined as the characteristic word of the site. In this case, the tag word may be a word input by the document creator as a representative feature of the content of the document.

In the determining of the at least one characteristic word, the at least one category word for classifying a document included in the site may be determined as the characteristic word of the site. That is, a category (eg, music, travel, photo, etc.) generated by the administrator of the site to classify the document may be a characteristic word of the site.

In operation S102, when the determined at least one characteristic word is related to the search word, the site may be determined as the related site for the search word.

For example, when a search word 'A' is selected, a site whose characteristic word is determined to be associated with 'A' among collected sites includes a document related to the search word 'A'. Therefore, it can be said that a site whose determined characteristic word is related to 'A' is related to 'A' search term.

In this case, when the search word and the characteristic word are not limited to the same thing and are related in the same or similar fields, the site including the characteristic word may be detected as the related site for the search word.

The method for providing a related site according to an embodiment of the present invention may provide the detected related site by linking the selected search word with a link (S103). In one example, providing a detected related site (S103) may provide a list of a plurality of related sites that are associated with a search term. Also, as an example, providing a detected related site (S103) may provide a document in which the selected search word is exposed among documents included in the detected related site.

2 is a diagram illustrating an example of exposing a search word introduced to a site according to a related site providing method according to an exemplary embodiment of the present invention.

FIG. 2 shows a search result 201 that provides a ranking of search terms flowing into the A site when the user inputs the A site 202. As mentioned earlier, the site can include a minihompy, a blog or a cafe.

Referring to the search word list 203 of FIG. 3, at least one search word most introduced among the search words introduced to the site A is illustrated. Each of the search terms may be exposed together with an inflow rate, and the search term ranking may be determined according to the inflow rate.

The related site providing method according to an embodiment of the present invention may provide a related site for the selected search word when the user selects the exposed search word. For example, when the user selects the first priority search word 'ab', the related site providing method may detect and provide a related site related to 'ab'. In the same manner, when the user selects the second ranking search term 'cd', the related site providing method may detect and provide a related site related to 'cd'. In this case, a detailed process of providing a related site for the selected search word will be described in detail with reference to FIG. 3.

3 is a diagram illustrating a process of providing a related site for a selected search word according to an embodiment of the present invention.

Referring to FIG. 3, when the user selects the search term 'ab' having the highest ranking, the A site 302, the B site 303, and the C site 304 related to the search word 301 and 'ab' are detected and provided. Can be. In one example, the detected sites may be provided in the form of a list, and the number of sites is not limited to the above example. In addition, the detected site may be exposed and provided together with the document including the selected search word 301. In addition, the detected site may be exposed and provided together with a document including a word associated with the selected search word 301.

As already described in FIG. 2, at least one search term entered into the site from the collected site, at least one index word for the document of the site, at least one tag word associated with the site, or at least to classify the document of the site. Any one of the category words may be determined as a characteristic word. The related site providing method may detect the site as the related site when the determined characteristic word and the search word 301 are related to each other.

4 is a flowchart illustrating a method for providing a related site according to another embodiment of the present invention. 4 illustrates a related site providing method for providing a related site related to a specific site, unlike FIG. 1.

In the method of providing a related site according to an embodiment of the present invention, at least one feature word for a site may be determined to generate a word vector of each feature word (S401). For example, in operation S401, the word vector of each feature word may be determined as the feature word of the site, at least one search word introduced to access the document of the site. In this case, the generating of the word vector of each characteristic word (S401) may include generating the word vector for the at least one search word by using the total number of accesses to the document of the site and the access times of each of the at least one search word. Can be generated. That is, when the characteristic word is a search word, the word vector may be calculated as a site inflow rate for the search word.

For example, generating a word vector of each feature word (S401) may determine at least one index word for a document included in the site as the feature word of the site. At this time, when a word that is frequently exposed or a word that is rarely exposed to the entire document of the site becomes an index word, the index word may not efficiently reflect the characteristics of the site. Accordingly, in the generating of the word vector of each feature word (S401), an index word belonging to a preset document exposure frequency range among the at least one index word may be determined as the feature word of the site.

At this time, generating the word vector of each characteristic word (S401) may calculate the word vector by calculating the ratio of each index word to the total index word in the document of the site. For example, the word vector may be calculated in the form of index 1 for 30% and index 2 for 20%.

For example, generating a word vector of each feature word (S401) may determine at least one tag word input when a document included in the site is a feature word of the site.

In this case, in the generating of the word vector of each characteristic word (S401), the word vector may be calculated by calculating a rate at which each tag word is exposed for all the tag words in the document of the site. For example, the word vector may be calculated in the form of tag word 1 of 30% and tag word 2 of 20%.

For example, generating a word vector of each feature word (S401) may determine at least one category word that classifies a document included in the site as the feature word of the site.

In this case, in the generating of the word vector of each characteristic word (S401), the word vector may be calculated by calculating a ratio of the exposure of each category word with respect to all category words in the document of the site. For example, the word vector may be calculated in the form of category word 1 for 25% and category word 2 for 14%. Unlike FIG. 1, the characteristic word in FIG. 3 may be determined for each of the sites to be compared with the sites to be compared.

In the method of providing a related site according to an embodiment of the present invention, a degree of word vector association between sites may be calculated using the generated site word vector (S402). At this time, the step S402 of calculating the word vector association between the sites may calculate the word vector association between the sites using the size of the site word vector. That is, the word vector association may be calculated based on weights between the word vectors.

In one example, calculating the word vector association between sites (S402) may calculate the angle between the site word vector using cosine similarity (cosine similarity). In other words, the cosine similarity can be said to use the dot product between the two vectors.

For example, suppose the characteristic word for site A is 'wine, music, travel to Europe' and the characteristic word for site B is 'wine, photo, travel to France'. The word vector for each characteristic word is (0.6, 0.3, 0.1) for the A site and (0.3, 0.5, 0.2) for the B site. Then, the word vector association may be determined as 0.6 * 0.3 + 0.1 * 0.2 = 0.2.

For example, when a high degree of association between characteristic words of a site is applied, a method of weighting each characteristic word may also be applied. That is, in the case of the A site and the B site, since the characteristic words of 'wine' are the same, the characteristic word of 'wine' can be given more weight than other characteristic words.

In a method of providing a related site according to an embodiment of the present invention, an associated site may be detected using the word vector degree of association (S403). For example, the detecting of the related site (S403) may include determining a distance between the sites according to the word vector relevance and sorting the sites in the order of the shortest distance between the sites to determine which sites belong to a preset ranking. Detecting as an associated site.

For example, suppose the word vector association of site B is 0.7 and the word vector association of site C is 0.4 with respect to site A on which the word vector association is based. Then, site A may be determined to be closer to site B than site C. Detecting the related site (S403) is to arrange the sites in the order of short distance to the site A as a reference, and to detect and provide only sites belonging to a predetermined rank (for example, 5th) as the related site. Can be.

FIG. 5 is a diagram for describing a process of detecting an associated site through a degree of association between a site and a site word vector between sites according to an embodiment of the present invention. Referring to FIG. 5, the method for providing a related site according to an embodiment of the present invention may detect and provide an associated site with respect to the A site 501 as a reference.

In this case, the related site providing method may detect the related site by determining the degree of association with the collected sites B, 502, C, 503, and D, 504. In this case, the related site providing method may determine at least one characteristic word from each of the A site 501, which is a reference, and the B site 502, C site 503, and D site 504 to be compared. As already mentioned above, feature words can be determined through search terms, index words, tag words, or category words for each site. In addition, the method of providing a related site may determine a word vector for each of the determined characteristic words.

In this case, the method for providing a related site may calculate a word vector association between the word vector of the A site 501 and the word vectors of the B site 502, the C site 502, and the D site 504. In addition, the method of providing a related site may determine that the distance between the sites is closer as the word vector association is greater. In addition, the related site providing method may be arranged into the C site 503, the D site 504, and the B site 502 in the order of close proximity to the A site 501. For example, suppose that the related site providing method can detect the top 2 positions as the related site. Then, as shown in Figure 5, the associated site providing method can detect and provide the C site 503 and the D site 504 belonging to the top two to the associated site.
