3 is a flowchart schematically illustrating an example of a data providing method according to an embodiment of the present invention. Hereinafter, a data providing method using the data providing apparatus 100 as described above with reference to FIG. 3 will be described.

Referring to FIG. 3, the data providing apparatus 100 may perform a step S100 of receiving a query input by the user from the user terminal 200. Here, the data providing apparatus 100 may provide a search site so that a user can input a query and provide a search result.

The data providing apparatus 100 receiving the query may perform a step S200 of generating a plurality of data search results including a query word from the database 130. [ Such a search result may include, for example, an association query term, a power link including a query term, a blog including a query term, a still image including a query term, a knowledge IN including a query term, expert information including a query term, A magazine including a query term, a biz scene including a query term, a moving image including a query term, a news including a query term, a site including a query term, a web document including a query term, and the like.

The data providing apparatus 100 generating a plurality of data search results may perform a step S300 of generating a summary tag set in which one or more tags tagged in each of a plurality of data are extracted. Here, the summary tag set may be an extraction result of tags tagged in each of the data included in the search result. In addition, the tags included in the summary tag set may include a query term or may not include a query term. The data providing apparatus 100 can calculate the tagged frequency in the data for each tag included in the summary tag set. For example, if a tag A is tagged in 100 items for 100 items as a search result including a query word, the frequency of the tag A can be calculated to be 100, and the tag B can be calculated for 50 items The frequency of the tag B can be calculated to be 50. [

In an alternative embodiment, if the same tag exists in a plurality of data created by the same user and includes a query word, the information transmission device 100 tracks the user account ID, and includes the tag in the summary tag set, Quot; 1 ". For example, for Data 1 to Data 3, which are created by the same user and contain query terms, Tag 1, Tag B and Tag C are tagged in Data 1, Tag A and Tag D are tagged in Data 2 The tag A, the tag C, and the tag E are tagged, the data providing device 100 adds the tag A, the tag B, the tag C, the tag D, and the tag E to the summary tag set, 1 ", the frequency of the tag C is" 1 ", the frequency of the tag D is" 1 ", and the frequency of the tag E is" 1 ". In an alternative embodiment, the data providing device 100 may arrange the tags in descending order according to the frequency with respect to the tags that have calculated the frequency within the summary tag set.

Then, the data providing apparatus 100 may perform the step of purifying the tag satisfying the purification condition (S400) from the summary tag set. Here, refining the tag may mean that the tag is excluded (deleted) from the summary tag set. The reason for refining the tag is that it can be determined that the tag to be refined is widely dispersed irrespective of the subject of the tag or the query word It is because. For example, if the frequency for the tag " entertainer " included in the summary tag set for the query term " Lee Hyo Lee " is more than the threshold value, the " entertainer "

The refinement condition may also include the case where the frequency of the tags from the summary tag set is greater than or equal to a threshold value (e.g., 10,000). When the frequency of the tag is equal to or greater than the threshold value, the data providing apparatus 100 determines that the purification condition is satisfied and refines the tag from the summary tag set. The purification condition may include a case where the name of the tag is the same as the category name. If the name of the tag is the same as the category name, the data providing device 100 can determine that the purification condition is satisfied and refine the tag from the summary tag set. Further, the refinement condition may include a case where the refinement condition is included in a predetermined upper group (for example, upper 1-2%) among the tags arranged in descending order according to the frequency. When the tag is included in the upper group, the data providing apparatus 100 determines that the refinement condition is satisfied and refines the tag from the summary tag set. Further, the purification condition may include a case where the data providing apparatus 100 is included in a category set in advance. For example, when the data providing apparatus 100 sets the tag included in the category of daily thinking / thought as the refining condition, the tag included in the daily thinking / thought category among the tags included in the summary tag set can be refined.

When the purification is completed, the data providing device 100 may perform step S500 of providing each tag in the summary tag set that has been purified to the association tag. Here, the associated tag may include one or more tags included in the summary tag set that has been refined. The data providing apparatus 100 may provide an association tag when providing the search result for the query term to the user terminal 200. [ The data providing apparatus 100 may locate the association tag at the top of the search result.
