Description

System and method for providing online community services based on SNS document similarity

[0001] The present invention relates to a device and method for providing an online community service, and more particularly, to a device and method for providing an online community service, and in general, in a conventional online community service where users with similar interests gather, in order for users of a social network service (SNS) or an online community service to find other users with similar interests, they must extract keywords from documents posted online and perform a search, individually search for each similar document presented in the search results to determine similarity, and then identify the poster of a similar document determined to have common interests with them to initiate communication and create a new sub-community. Therefore, the process for forming a sub-community among users with common interests is very cumbersome and inconvenient. In order to solve the problem of the conventional online community services, when users of an SNS or an online community search for a specific document posted online, the device is configured to calculate the similarity between the document and other documents and provide similar documents similar to the document and information related to document similarity between the document and similar documents, thereby enabling each user to more easily and conveniently create a sub-community and communicate with the posters of similar documents within the online community. This relates to a system and method for providing an online community service based on SNS document similarity.

[0002] In addition, the present invention relates to a system and method for providing an online community service based on SNS document similarity, which is configured to calculate the similarity between a specific document posted online by users of SNS or online communities and provide similar documents similar to the document and information related to document similarity between the document and similar documents, and to directly invite users who have posted similar documents to the sub-community, thereby enabling each user to more easily and conveniently create and communicate with posters of similar documents and simultaneously enabling the process of inviting new members to the created sub-community to be performed more quickly and easily.

[0003]

[0004] Recently, with the development of Internet and IT technology and the widespread use of smartphones, various online community services for communication between individuals, such as social network services (SNS), are increasing, and the number of users of various online communities is also increasing significantly.

[0005] In other words, SNS is an online platform that creates and strengthens social relationships through free communication, information sharing, network expansion, and business cooperation between users. SNS users can register as members and upload documents, photos, videos, etc., such as posts, comments, and quotes they have written, and can view posts, comments, documents, photos, and videos uploaded by others, allowing them to communicate freely 1:1 or N:N regardless of time and place.

[0006] Additionally, it should be noted that documents uploaded to these SNS or online communities may include, but are not necessarily limited to, posted documents, comments on posted documents, comments (replies) to comments, profile introductions, sub-community introductions, keywords entered by users, and other text or numeric information entered by users or linked.

[0007] In addition, as presented in Korean Patent Publication No. 10-1815478 entitled “Online community service provision device and method corresponding to a game user group” and Korean Patent Publication No. 10-1632889 entitled “Game service method and system using SNS,” various devices and methods have been presented in the past to connect users with similar interests among SNS or online community service users, but the contents of the above-mentioned prior art had the following limitations.

[0008] Here, for each document posted on SNS or an online community, the similarity between that document and other documents excluding that document can be calculated 1:1 based on one document, and therefore, in the present invention, the document that serves as the standard for judging similarity is called a primary document, and a document that is similar to the primary document is defined as a similar document to the primary document.

[0009] That is, in general, in existing SNS or online community services, in order for users to find and communicate with users who have similar interests to themselves, they must first search for similar documents similar to a specific primary document through keyword searches, etc., subjectively judge the similarity of each similar document to the primary document, identify the user who posted the similar document, and then select the user to create a sub-community such as a chat or channel.

[0010] Therefore, existing SNS or online community services had the inconvenience of having to go through a somewhat complicated process of extracting keywords from the primary document to find users similar to oneself -> searching with the extracted keywords -> looking up each similar document presented in the search results to determine similarity to the primary document -> confirming the poster of the similar document -> initiating communication with the poster of the primary document and similar document.

[0011] Moreover, existing SNS or online community services, when inviting non-members to a sub-community after creating a sub-community through the process described above, have to go through the process of searching for the non-member's information and documents posted by the non-member to subjectively determine whether they match the sub-community and then decide whether to invite them, which is cumbersome.

[0012] Therefore, in order to solve the limitations of the SNS or online community services of the prior art as described above, it is desirable to propose a new SNS document similarity-based online community service provision system and method configured to calculate the similarity between a specific document posted online by users of the SNS or online community and provide similar documents similar to the document and information related to document similarity between the document and similar documents, thereby enabling each user to create and communicate with the posters of similar documents more easily and conveniently. However, a device or method that satisfies all of these needs has not yet been proposed.

[0047]

[0048] Hereinafter, with reference to the attached drawings, a specific embodiment of an online community service providing system and method based on SNS document similarity according to the present invention will be described.

[0049] Here, it should be noted that the contents described below are only one embodiment for carrying out the present invention, and the present invention is not limited to the contents of the embodiments described below.

[0050] In addition, in the description of the embodiments of the present invention below, it should be noted that for the sake of brevity, detailed descriptions of parts that are identical or similar to the contents of prior art or that can be easily understood and implemented by those skilled in the art have been omitted.

[0051] Continuing, with reference to the drawings, the specific details of the system and method for providing an online community service based on SNS document similarity according to the present invention will be described.

[0052] More specifically, first, referring to FIG. 1, FIG. 1 is a block diagram schematically showing the overall configuration of an online community service providing system (10) based on SNS document similarity according to an embodiment of the present invention.

[0053] As shown in Fig. 1, the SNS document similarity-based online community service providing system (10) according to an embodiment of the present invention can be broadly divided into a plurality of user terminals (11) for each user to request and receive a desired service, and a service server (12) that is linked to each user terminal (11) to receive a user's request and perform processing to provide a corresponding service.

[0054] Here, the user terminal (11) mentioned above can be configured by installing a dedicated application program that is linked to the service server (12) on an information processing device such as a PC or a laptop, or, preferably, a personal portable information and communication terminal such as a user's smartphone or tablet PC, thereby enabling implementation with a simpler configuration and lower cost without the need to implement dedicated hardware separately.

[0055] In addition, the above-described service server (12) may be configured to perform processing such as calculating a similarity score between a document selected by a user or a document uploaded by a user and other documents, as described below, presenting a list of similar documents according to predetermined settings, inviting the publisher of a similar document selected by a user to a user's sub-community, or creating a new sub-community so that users with similar interests can communicate more conveniently and easily with each other.

[0056] More specifically, referring to FIG. 2, FIG. 2 is a conceptual diagram schematically illustrating a configuration in which a service server (12) of an SNS document similarity-based online community service providing system (10) according to an embodiment of the present invention analyzes the similarity between a specific document posted online and other documents and presents a list of similar documents according to the similarity score.

[0057] As shown in Fig. 2, documents posted online, such as on SNS, can be calculated 1:1 in terms of similarity between a specific document (the first document) and other documents excluding that document. Accordingly, in the following examples, the document that serves as the standard for judging similarity is referred to as the first document, and a document that is similar to the first document is defined as a similar document to the first document.

[0058] At this time, the method for calculating the similarity between documents may be, for example, the Bag-of-Words (BOW) method, which uses the frequency count of the mention of words, or the Term Frequency-Inverse Document Frequency (TF-IDF) weight model, and the Word2vec, Vector Space, Doc2Vec, GloVe models based on artificial neural networks, but is not necessarily limited to these configurations.

[0059] That is, the present invention is not particularly limited and can be applied to all things that determine the similarity of documents and words or morphemes included in documents, and therefore, it should be noted that the present invention can be applied by modifying and changing it in various ways as needed by those skilled in the art within a scope that does not deviate from the spirit and essence of the present invention.

[0060] In addition, as for more specific details on the method for calculating similarity between documents using BOW or an artificial neural network model as mentioned above, since it is a matter that can be appropriately implemented by those skilled in the art by referring to the contents of document similarity calculation algorithms of the prior art, in the present invention, for the sake of concise explanation, it should be noted that a detailed description of the contents that are obvious to those skilled in the art from the contents of the prior art as mentioned above or that can be easily understood and implemented by those skilled in the art by referring to literature of the prior art, etc., has been omitted.

[0061] Furthermore, the service server (12) may be configured to perform a process of tagging the calculated document similarity score to the meta information of the first document and similar documents for the first document, respectively, when the document similarity score is calculated between the first document and other documents excluding the first document as described above, thereby enabling the user to quickly search for documents similar to the first document on the same screen (web page) when searching for the first document.

[0062] In addition, the service server (12) may be configured to calculate, when a new document is registered, a similarity score between documents with respect to the newly registered document and an existing document, update the similarity score between documents and information about similar documents based on the calculation result, and perform a process of tagging each document.

[0063] Therefore, with the configuration described above, when a user views a first document, he or she can view other documents similar to the first document together on the same screen, thereby increasing convenience when viewing documents and improving user experience.

[0064] That is, referring to FIG. 3, FIG. 3 is a conceptual diagram schematically showing an example of the configuration of a document search screen provided through a service server (12) of an online community service provision system (10) based on SNS document similarity according to an embodiment of the present invention.

[0065] As shown in Fig. 3, when a user searches for the first document, the search window of the first document may be configured to display information about the publisher who posted the first document (such as the publisher's name, nickname, or ID), information about the posting time of the posted document, and the contents of the posted document (such as the title of the posted document and the body of the posted document).

[0066] In addition, as shown in FIG. 3, the number of similar documents similar to the first document may be displayed at the bottom of the first document search window, and a similar recommendation setting button may be displayed to enable the user to set an algorithm for recommending similar documents.

[0067] More specifically, for example, when a user presses a similar recommendation setting button, the system may be configured to set an upper limit and a lower limit of a similarity score that serves as a criterion for selecting similar documents for the first document, and the system may be configured to select similar documents based on the posting date of the similar documents, or the system may be configured to adjust the sorting order of similar documents based on various criteria such as order of similarity, order of time based on posting date, order of number of views, order of number of comments, etc.

[0068] In addition, as shown in FIG. 3, a search window for searching for similar documents of the first document according to similar recommendation settings is displayed at the bottom of the first document search window, and the similar document search window can be configured to present similar documents in order according to the sorting order set in the similar recommendation settings (by similarity, by time based on posting date, by number of views, by number of comments, etc.).

[0069] At this time, each similar document may be configured to display a similarity score between the first document that serves as a reference and the similar document, and may be configured to display common keywords between the first document that serves as a reference and the similar document, and keywords that are included in the similar document but not included in the first document (non-common keywords).

[0070] Furthermore, as shown in FIG. 3, the document search page can be configured to provide a function that allows users to selectively search only documents corresponding to a specific category assigned to a posted document when selecting the category, and such categories can be assigned by the publisher when posting the document, so that users can select the category that best matches the content or purpose of the posted document when posting the document, and when the viewer selects a category that matches the content or purpose that he or she wants to search, he or she can selectively search only documents created under the category assigned.

[0071] In addition, as shown in FIG. 3, the document search page can be configured to provide a function that allows selective searching of only documents corresponding to a specific sub-community assigned to a posted document when that sub-community is selected, and similar to categories, these communities can be assigned by the publisher when posting the document, so that when posting, the publisher can select the sub-community that best matches the content or purpose of the posted document, and when the viewer selects the sub-community that matches the content or purpose that he or she wants to search, the viewer can be configured to selectively search only documents created by being assigned that sub-community.

[0072] In addition, in a sub-community, only members who have joined the sub-community can upload posted documents, and the sub-community administrator can set it to public / private, so that in the case of a public sub-community, all users can view the posted documents in the sub-community, but if it is set to private, only members who have joined the sub-community can view the posted documents.

[0073] Moreover, these sub-communities typically have the properties and form of one or more sub-communities established within an online community, and can be configured so that each sub-community manager has the authority to define the character of the community and to manage members and grant access rights.

[0074] Here, the above-mentioned sub-community may be configured so that the user can select the type of sub-community he or she desires, including the types of various existing online community services currently in service, such as chats, channels, blogs, cafes, SNS, etc., which enable 1:1 and N:N communication, in addition to the sub-community created through the service server (12) of the SNS document similarity-based online community service providing system (10) according to the embodiment of the present invention.

[0075] As described above, according to the present invention, the first document and a similar document to the first document are presented on the same screen, and each document is provided with a sub-community connection button, so that the process of inviting or communicating with the publisher of the first document and a similar document to the sub-community can be made more convenient and easy.

[0076] In addition, when a user selects the online community connection button, the function can be configured to register the publisher of a specific document in an invitation list, that is, when a user wants to invite the publisher of a specific document to a specific sub-community, the user can register the publisher of the specific document in an invitation list, then search the invitation list in the specific sub-community, and select and invite the publisher of the specific document from the invitation list based on the publisher of the specific document and the document information registered by the publisher.

[0077] Here, in particular, when inviting a publisher of a specific document to a specific sub-community as described above, it is necessary to select publishers from the already registered invitation list and invite only publishers who have written documents that fit the sub-community.

[0078] In other words, since most of the existing online community services only provide the poster's information (nickname, ID, etc.) in the invitation list, there is a limitation that it is difficult for the user to judge on the invitation list screen whether the purpose of the online community and the purpose of the document written by the poster to be invited are aligned. As a result, when the user invites another poster, there was the inconvenience of having to search and view the documents written by the poster one by one to judge the content before inviting them.

[0079] Accordingly, in the present invention, an SNS document similarity-based online community service provision system (10) is proposed that allows a user to more conveniently and easily invite a poster that matches a sub-community without having to separately search for the poster's posted document by providing poster information and information about the posted document together in the invitation list displayed when inviting a non-member from a sub-community.

[0080] That is, referring to FIG. 4, FIG. 4 is a conceptual diagram schematically showing an example of the configuration of an online community invitation screen provided through a service server (12) of an online community service providing system (10) based on SNS document similarity according to an embodiment of the present invention.

[0081] As shown in FIG. 4, according to the present invention, when a user searches for a document and registers the poster who posted the document in a specific document in an invitation list, not only the poster information of the document but also the information (title, body, main keywords) of the document are registered, and when inviting a non-member in a specific sub-community, the invitation list displayed is configured to provide the poster information who posted the specific document, information about the document, and information about the similarity with the introductory document of the sub-community, so that the user can more conveniently and easily select and invite only the posters who have written documents that are suitable for the purpose of the sub-community without having to separately search and search for the poster's posted documents to determine the contents.

[0082] In addition, as shown in FIG. 4, the invitation list can be configured to display information about a specific document along with the document similarity between the introductory document of the sub-community and the document in question, thereby enabling the user to more easily select a publisher who has written a document that matches the sub-community.

[0083] In addition, referring to FIG. 5, FIG. 5 is a conceptual diagram schematically showing a case where a member document search window is displayed as an example of a configuration of a specific sub-community introduction document display screen provided through a service server (12) of an online community service provision system (10) based on SNS document similarity according to an embodiment of the present invention.

[0084] As shown in FIG. 5, according to the present invention, the document similarity between an individual document searched within a sub-community and an introductory document for the corresponding sub-community can be calculated and displayed, and from this configuration, a user searching for a document can easily determine how similar various documents in the sub-community are to the introductory document of the corresponding sub-community, and thereby quickly and easily select and search for a document that is more suitable for the corresponding sub-community.

[0085] Furthermore, the above-described function can be configured to provide the same document search screen not only for documents of members who have joined the sub-community but also for documents posted by non-members who have not joined the sub-community.

[0086] More specifically, referring to FIG. 6, FIG. 6 is a conceptual diagram schematically illustrating a case in which a non-member document search window is displayed as an example of a configuration of a specific sub-community introduction document display screen provided through a service server (12) of an online community service provision system (10) based on SNS document similarity according to an embodiment of the present invention.

[0087] That is, since document similarity can be calculated between documents on SNS or online regardless of whether they are posted in a specific sub-community, documents posted in a specific sub-community can also have a document similarity score calculated with all other documents uploaded to SNS, and thus documents posted in a specific sub-community and documents not posted in a specific sub-community can be searched together when searching for similar documents.

[0088] Accordingly, as shown in FIG. 6, according to the present invention, the document similarity with the introductory document of the sub-community can be configured to be displayed together with the document of a non-member who has not joined the sub-community, and from this configuration, the member of the sub-community can check the information of the non-member (information of the document poster), the information about the document posted by the non-member, and the document similarity score all on the same screen, so the process of deciding whether to invite the non-member to the sub-community can be greatly shortened.

[0089] That is, members of a sub-community can determine whether a document written by a non-member is compatible with the sub-community based on the document written by the non-member and the information about the non-member, and the document similarity information between the document written by the non-member and the introductory document of the sub-community, and invite the non-member by clicking the community invitation button displayed on one side of the document posted by the non-member. This makes the process of inviting a non-member to the sub-community faster and easier.

[0090] At this time, the invitation method is to register the non-member in the invitation list as described above, then search the invitation list in the sub-community to which the invitation is to be made, and select the poster of the document from the invitation list based on the poster of the specific document, the document information registered by the poster, and the document similarity between the introductory document of the sub-community and the document in question.

[0091] Accordingly, according to the present invention, from the configuration described above, similar documents can be grouped and searched at once by calculating the similarity of documents uploaded on SNS, and sub-communities such as chats or channels can be created more easily with users who have posted similar documents, thereby enabling one-stop communication between users who have posted similar documents.

[0092] In addition, according to the present invention, by calculating the document similarity between an introductory document representing the characteristics of the sub-community and a specific posted document and utilizing it to select non-members to invite to the sub-community, the process of a member of the sub-community selecting a non-member who has posted a document matching the sub-community and inviting the non-member to the sub-community can be more easily and conveniently carried out.

[0093] In addition, according to the present invention, when selecting a non-member to invite to a sub-community, the invitation list is configured to display the document similarity between the introductory document of the sub-community and the document posted by the non-member to be invited, thereby eliminating the inconvenience of the user having to individually check whether the document of the non-member to be invited is in line with the purpose of the sub-community.

[0094] That is, referring to FIG. 7, FIG. 7 is a flowchart schematically showing the overall processing process of an online community service provision system (10) based on SNS document similarity according to an embodiment of the present invention configured as described above.

[0095] As illustrated in FIG. 7, the method for providing an online community service based on SNS document similarity according to an embodiment of the present invention can be broadly divided into a similarity calculation step (S10) in which processing is performed to calculate a similarity score between a specific document selected or uploaded by a user and other documents, a similar document list creation step (S20) in which processing is performed to create a list of similar documents according to predetermined settings based on the similarity score calculated in the similarity calculation step (S10), a similar document search step (S30) in which processing is performed to display a search screen for a specific similar document when the user selects the specific similar document from the list created through the similar document list creation step (S20), and an invitation step (S40) in which processing is performed to register the poster who posted the document in the invitation list when the user selects the community invitation button displayed on the similar document search screen displayed through the similar document search step (S30) and display various information including the poster information, the posted document information, the similarity score information, and an introductory document for a specific sub-community together.

[0096] In addition, although not shown, the above method may further include a sub-community member document search step in which, when a user searches for a document posted by a member of a specific sub-community in a specific sub-community, a list of similar documents is displayed together with an introductory document for the sub-community and based on a similarity score with the introductory document for the sub-community, and for each similar document, poster information, posted document information, and similarity score information with the introductory document for the sub-community are displayed together, and a sub-community non-member document search step in which, when a user searches for a document posted by a non-member of the sub-community in a specific sub-community, a list of similar documents is displayed together with an introductory document for the sub-community and based on a similarity score with the introductory document for the sub-community, and for each similar document, poster information, posted document information, similarity score information with the introductory document for the sub-community, and a community invitation button are displayed together.

[0097] Here, it should be noted that since the more specific processing process of each step described above can be configured as described above with reference to FIGS. 1 to 6, detailed descriptions of overlapping content have been omitted here for the sake of brevity.

[0098] Accordingly, as described above, an online community service providing system and method based on SNS document similarity according to an embodiment of the present invention can be implemented, and thereby, according to the present invention, when users of SNS or online communities search for a specific document posted online, the similarity between the document and other documents is calculated, and similar documents similar to the document and information related to document similarity between the document and similar documents are provided, and based on the information, a user who posted a similar document can be directly invited to a specific sub-community, so that each user can more easily and conveniently create and communicate with the posters of similar documents in an online community, and at the same time, the process of inviting new members to the created sub-community can also be more quickly and easily performed.

[0099] Hereinafter, the detailed contents of the SNS document similarity-based online community service providing system and method according to the present invention have been described through the embodiments of the present invention as described above, but the present invention is not limited to the contents described in the embodiments above, and therefore, it will be obvious that the present invention can be modified, changed, combined, and replaced in various ways by a person having ordinary knowledge in the technical field to which the present invention pertains according to design needs and other various factors.
