1 is a diagram illustrating a configuration of a search system that provides a conversation based search. 2 is a flowchart provided to explain a topic-based search providing method.

Referring to FIG. 1, the search system 100 may include a document collector 110, a searcher 120, a response index calculator 130, an alignment unit 140, and an information provider 150. have.

1 and 2, first, the searcher 120 may extract documents in which a creation time is set from the collected documents (210).

In this case, the document collecting unit 110 may collect various types of documents such as a photo, an article, a web site address, and the like by using a web crawler. Then, the search unit 120 may extract the documents whose creation time is set from the collected documents.

For example, the searcher 120 may extract documents including clear articles, such as newspaper articles, posts, blog posts, and Twitter posts, from the collected documents. In this case, when the writing time of the document is clear, the documents composed of the text may include not only text but also an image and a web site address.

Subsequently, the searcher 120 may compare the extracted documents and cluster the extracted documents for each document that is the same document or the contents of the document are similar to each other (220). In this case, the searcher 120 may determine, as target documents, similar documents among documents having similarity between documents.

For example, when 100 documents are extracted, the searcher 120 may cluster 30, 25, 17, 15, and 13 documents having similar contents among the extracted documents so that they belong to the same cluster. have. That is, 30 documents may belong to the first cluster, 25 documents to the second cluster, 17 documents to the third cluster, 15 documents to the fourth cluster, and 13 documents to the fifth cluster.

The search unit 120 may determine the representative document for each cluster by using the documents belonging to the cluster (230).

For example, the searcher 120 may determine a document having the highest response index among documents belonging to the cluster as the representative document.

In this case, the response index may include at least one of the number of comments on the document, the number of bookmarks of the document in various bookmark sites, the number of times the document is cited in another document, and the rating of the document. Can be. Here, the rating of the document may include a number of times recommended in various review sites or an evaluation value.

As another example, the search unit 120 may determine a document that is highly related to a search keyword among the documents belonging to the cluster as the representative document. Here, the document having a high relation with the search keyword may be a document having a large number of clicks by other terminals among documents belonging to the cluster. That is, a document having a large number of clicks by another terminal among documents belonging to the cluster may be determined as the representative document.

Subsequently, the response index calculator 130 may calculate a response index of the representative document determined for each cluster (240).

In this case, the response index calculator 130 may calculate the response index of the representative document as the sum of the response indexes of the documents belonging to the cluster. For example, when 10 documents belong to a cluster, and the response index of 10 documents corresponds to 1 to 10, the response index calculator 130 may calculate the response index of the representative document as 55, which is a sum of 1 to 10. Can be. In the same manner, the response index calculator 130 may calculate response indexes of representative documents belonging to a plurality of clusters, respectively.

In addition, the alignment unit 140 may arrange the determined representative documents according to an option (250). Here, the options may include a sorting option by time and a sorting option by response index. In this case, the option may be preset, or one of the sorting option by time and the sorting option by response index may be input from the user.

For example, as illustrated in FIG. 3, when the time-based sorting option is used, the sorting unit 140 may sort the representative documents in the order of the created time of the representative document.

Subsequently, the information providing unit 150 may provide the terminal with information about the arranged representative documents and information about the response index of the representative documents. In this case, the information providing unit 150 may also provide the terminal with information on the preparation time of the arranged representative documents. Then, the terminal may display the sorted representative documents, the response index of the representative documents, and the creation time together (260).

For example, the information provider 150 may provide a terminal with a web page including link information and response indexes of representative representative documents. Then, the terminal may display the response documents of the representative documents and the representative documents arranged based on the web page.

In this case, the response index of the representative document may be visualized and displayed. For example, as shown in FIG. 3, the response index 310 of the representative document may be displayed numerically, or may be displayed in a color or a gradient graph divided according to the number of special characters such as a star shape, the height of the response index, and the like. have.

On the other hand, when the response index sorting option is used, the alignment unit 140 may sort the representative documents in the response index order of the representative document. Then, as in the case where the time-based sorting option is used, the representative documents arranged in response index order, the response index of the representative document, and the creation time may be displayed together on the terminal.

In this case, when a document is selected by the terminal among the displayed representative documents, the information providing unit 150 may provide the terminal with information about documents belonging to the cluster of the selected representative document in the form of a web page. Then, documents belonging to the cluster of the selected representative document may be displayed on the terminal.

For example, as illustrated in FIG. 4, when a fourth representative document having a response index of 43 is selected, documents belonging to the cluster of the fourth representative document selected regardless of news, blogs, and bulletin boards may be displayed 410.

In this case, when the number of documents belonging to the cluster of the fourth representative document is equal to or greater than a predetermined threshold value, the information provider 150 may provide scrolling. Then, the terminal may display all documents belonging to the cluster of the representative document by using the scroll.

As another example, as illustrated in FIG. 5, the information providing unit 150 may provide only the documents corresponding to the news article among the documents belonging to the selected fourth representative document cluster to the terminal in the form of a web page. Then, only documents corresponding to the news article among the documents belonging to the selected fourth representative document cluster may be displayed on the terminal.

Meanwhile, when the detailed view option of the arranged representative documents is selected, the information provider 150 may provide detailed information of each representative document in the form of a web page. Then, as illustrated in FIG. 6, detailed information of each representative document may be displayed on the terminal.

In the above description, the representative documents are sorted in order of time or response index. However, this is an exemplary embodiment, and the search system 100 may sort the representative documents using both the time order and the response index.

For example, the search system 100 may extract documents corresponding to a creation time within a predetermined reference time from among the representative documents, and sort the extracted representative documents in order of high response index. That is, the representative documents recently created among the representative documents may be sorted in ascending order of response index.
