Description

Technical Field

[0001] This invention relates to the field of computers, and more specifically, to a method and apparatus for updating a knowledge graph, a storage medium, and an electronic device. Background Technology

[0002] Currently, the process of acquiring user needs and providing feedback based on those needs largely relies on search or recommendation algorithms. In user search, users directly input keywords and select the desired content from the results. This requires users to conduct targeted searches and have a clear objective for the feedback they seek. It's difficult to effectively recommend products to users who lack a clear target audience. In contrast, app recommendations, based on user behavior (e.g., listening to music), use various recommendation algorithms to display lists in the app at appropriate times. Users then select songs they are interested in. However, in this process, users don't accurately understand why the app recommends these songs; they are in a passive state. Furthermore, since user preferences may change over time, continuous recommendations from app algorithms can lead to increasingly homogenized service types, failing to truly meet user needs.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0070] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0071] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0072] The present invention will now be described with reference to the following embodiments:

[0073] According to one aspect of the present invention, a method for updating a knowledge graph is provided. Optionally, in this embodiment, the above-described knowledge graph updating method can be applied to, for example... Figure 1 The hardware environment shown consists of server 101 and user terminal 103. For example... Figure 1As shown, server 101 connects to terminal 103 via a network and can be used to provide services to user terminals or clients installed on user terminals. Clients can be video clients, instant messaging clients, browser clients, educational clients, game clients, etc. Database 105 can be set up on the server or independently of the server to provide data storage services to server 101, such as a game data storage server, audio data storage server, etc. The aforementioned network can include, but is not limited to, wired networks and wireless networks. The wired network includes local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). The wireless network includes Bluetooth, Wi-Fi, and other networks that enable wireless communication. User terminal 103 can be a terminal configured with media information applications and / or target game applications, and can include, but is not limited to, at least one of the following: mobile phones (such as Android phones, iOS phones, etc.), laptops, tablets, handheld computers, MIDs (Mobile Internet Devices). Internet devices (mobile internet devices), PADs, desktop computers, smart TVs, and other computer devices. The aforementioned server can be a single server, a server cluster composed of multiple servers, or a cloud server, and may include, but is not limited to, routers or gateways. The application 107 using the aforementioned knowledge graph update method is displayed through the user terminal 103. The application 107, configured on the terminal for knowledge graph updates, displays a first interactive interface and the target knowledge graph. A first interactive operation is performed on a second graph node on the first interactive interface, and the application 107 can respond to this first interactive operation. The application 107 is connected to the server 101 via a network. The application can also be configured as a webpage, a mini-program, or an app to display the target knowledge graph on the first interactive interface and execute the aforementioned knowledge graph update method. The above is merely an example, and no limitations are imposed in this embodiment.

[0074] Alternatively, as an alternative implementation method, such as Figure 2 As shown, the methods for updating the knowledge graph include:

[0075] S202, the target knowledge graph is displayed on the first interactive interface. The target knowledge graph includes a first graph node and a first group of graph nodes. Each graph node in the first graph node and the first group of graph nodes displays a corresponding keyword. The first group of graph nodes is displayed as the adjacent nodes of the first graph node. The keywords on the first graph node and the keywords on the first group of graph nodes are related.

[0076] S204, on the first interactive interface, obtain the first interactive operation to be performed on the second graph node, wherein the second graph node is a graph node in the first group of graph nodes, and the first interactive operation is used to select the second graph node;

[0077] S206, in response to the first interactive operation, the newly added second set of graph nodes is displayed on the first interactive interface. The second set of graph nodes is displayed as the adjacent nodes of the second graph node. Each graph node in the second set of graph nodes displays a corresponding keyword. The keywords on the second graph node are related to the keywords on the second set of graph nodes. The target knowledge graph includes the second set of graph nodes.

[0078] Optionally, in this embodiment, the aforementioned target knowledge graph can be applied to application scenarios that make recommendations based on user needs, such as audio, video, text, images, applications, and products.

[0079] Optionally, in this embodiment, as Figure 3 As shown, taking the above-mentioned target knowledge graph applied to the audio recommendation field as an example, through the pre-configured or randomly generated first set of graph nodes 302, wherein the first set of graph nodes 302 includes a first graph node 304 and a second graph node 306, the keyword "singer A" on the first graph node 304 is related to the keyword "region B" on the second graph node 306. Clicking the second graph node 306 responds to the click operation and displays the second set of graph nodes 308 on the first interactive interface, wherein the keyword "singer B" on graph node 310 and the keyword "singer C" on graph node 312 in the second set of graph nodes 308 are both related to the keyword "region B" corresponding to the second graph node 306.

[0080] Optionally, in this embodiment, as Figure 4As shown, taking the application of the aforementioned target knowledge graph in the field of application recommendation as an example, a first set of graph nodes 402 is pre-configured or randomly generated. This first set of graph nodes 402 includes a first graph node 404 and a second graph node 406. The keyword "C" on the first graph node 404 is associated with the keyword "E" on the second graph node 406. Clicking on the second graph node 406 responds to the click operation, displaying the second set of graph nodes 408 on the first interactive interface. The keyword "F" on graph node 410 and the keyword "G" on graph node 412 in the second set of graph nodes 408 are both associated with the keyword "E" corresponding to the second graph node 406. The keywords A, B, C, D, E, F, and G can include, but are not limited to, keywords associated with applications. For example, A and B might represent different application names, C, F, and G might represent different application parent companies, and E and D might represent application types.

[0081] Optionally, in this embodiment, the above-mentioned graph nodes can be represented using different shape rules according to different keyword types, for example, such as Figure 3 As shown, circular graph nodes are used to represent the keyword "song", square graph nodes are used to represent the singer, and diamond graph nodes are used to represent the region to which the singer belongs.

[0082] Optionally, in this embodiment, the above-mentioned graph nodes can be represented by different colors according to different keyword types, for example, such as Figure 3 As shown, the graph nodes with the keyword "song" are configured in red, the graph nodes with the keyword "singer" are configured in blue, and the graph nodes with the keyword "singer's region" are configured in yellow.

[0083] Optionally, in this embodiment, the adjacent nodes are used to indicate that the keywords of the graph nodes in the adjacent state have an association relationship. The association relationship may include, but is not limited to, subordinate and parallel relationships. Different association relationships can also be set based on different application scenarios, for example, Figure 3 As shown, song A is a work by singer A. Therefore, the graph node with the keyword "song A" is associated with the graph node with the keyword "singer A".

[0084] Optionally, in this embodiment, the first interactive operation may include, but is not limited to, touch operation methods such as clicking, long pressing, releasing, tapping, and swiping, or interactive operations such as voice recognition, VR, and AR that can interact with the second graph node.

[0085] Optionally, in this embodiment, the above-mentioned response to the first interactive operation to display the newly added second set of graph nodes on the first interactive interface may include, but is not limited to, displaying a pre-configured second set of graph nodes associated with the keywords of the second graph node, or may include, but is not limited to, searching according to the keywords of the second graph node to obtain the above-mentioned second set of graph nodes of a preset type.

[0086] The above is merely an example, and this embodiment does not impose any specific limitations.

[0087] This embodiment displays a first graph node and a first group of graph nodes on a first interactive interface. Each graph node in the first graph node and the first group of graph nodes displays a corresponding keyword. The keywords on the first graph node and the keywords on the first group of graph nodes are related. A first interactive operation for selecting a second graph node is obtained on the first interactive interface. In response to the first interactive operation, a newly added second group of graph nodes is displayed on the first interactive interface. The second group of graph nodes is displayed as adjacent nodes of the second graph node. Each graph node in the second group of graph nodes displays a corresponding keyword. The keywords on the second graph node and the keywords on the second group of graph nodes are related. By standardizing and organizing user needs based on keywords and establishing relevant knowledge graphs, the purpose of providing users with recommendation services that truly meet their needs is achieved. This improves the accuracy of recommended content and optimizes the user experience, thereby solving the technical problems of related technologies that are difficult to truly meet user needs and have low accuracy in updating recommended content.

[0088] In an optional embodiment, the method further includes: in response to a first interactive operation, canceling the display of graph nodes other than the second graph node in the first group of graph nodes on the first interactive interface, or, a group of graph nodes other than the second graph node in the first group of graph nodes, wherein the keywords on the group of graph nodes are the same type of keywords as the keywords on the second graph node.

[0089] Optionally, in this embodiment, the above-mentioned method of canceling the display may include, but is not limited to, deleting all graph nodes in the first group of graph nodes except for the second graph node, or deleting a group of graph nodes in the first group of graph nodes except for the second graph node.

[0090] For example, such as Figure 5 As shown, in response to the first interactive operation, after displaying the second group of graph nodes 502, the graph nodes 508 other than the second graph node 506 in the first group of graph nodes 504 are canceled in the first interactive interface, or, a group of graph nodes 508 other than the second graph node 506 in the first group of graph nodes 504.

[0091] This embodiment achieves the technical effect of simplifying the display interface by canceling the display of graph nodes other than the second graph node in the first group of graph nodes, or displaying a group of graph nodes other than the second graph node in the first group of graph nodes. This makes it easier for users to find newly added graph nodes more quickly for subsequent selection, improves the accuracy of recommended content, and optimizes the user experience.

[0092] In an optional embodiment, the method further includes: when the display of all graph nodes in the first group of graph nodes except the second graph node is cancelled on the first interactive interface, obtaining a second interactive operation performed on the first graph node on the first interactive interface; in response to the second interactive operation, displaying all graph nodes in the first group of graph nodes except the second graph node on the first interactive interface; when the display of a group of graph nodes in the first group of graph nodes except the second graph node is cancelled on the first interactive interface, obtaining a second interactive operation performed on the first graph node on the first interactive interface; in response to the second interactive operation, displaying a group of graph nodes in the first group of graph nodes except the second graph node on the first interactive interface.

[0093] Optionally, in this embodiment, the graph node that is in the canceled display state can be redisplayed by performing the second interactive operation on the first graph node, including but not limited to. The second interactive operation can be set to be the same as or different from the first interactive operation.

[0094] For example, the first interactive operation is set to click, and the second interactive operation is set to swipe. After the swipe operation is obtained on the first graph node, a group of graph nodes other than the second graph node in the first group of graph nodes is displayed on the first interactive interface.

[0095] like Figure 5 As shown, by performing a second interactive operation on the first graph node 510, a group of graph nodes other than the second graph node are displayed on the first interactive interface.

[0096] The above is merely an example, and this embodiment does not impose any specific limitations.

[0097] This embodiment provides users with more options, allowing them to adjust their selection of graph nodes at any time according to the actual situation. It also fully displays the selection history of graph nodes, records the content selected by the user, and optimizes the user experience.

[0098] In an optional embodiment, the method further includes: if a second interactive operation is performed on the first graph node on the first interactive interface, canceling the display of the second group of graph nodes on the first interactive interface.

[0099] Optionally, in this embodiment, after obtaining the second interactive operation, in addition to displaying the first group of atlas nodes excluding the second atlas node, the display of the second group of atlas nodes can also be cancelled. For example, as shown... Figure 5 As shown, after performing the second interactive operation on the first graph node 510, the second set of graph nodes is de-displayed on the first interactive interface.

[0100] This embodiment allows users to adjust the selection of graph nodes at any time according to the actual situation, and can fully display the selection history of graph nodes, thus optimizing the user experience.

[0101] In an optional embodiment, displaying the newly added second set of graph nodes on the first interactive interface includes: obtaining a set of keywords that are related to the keywords on the second graph nodes from the first information set; displaying the first set of keywords in the corresponding graph nodes in the second set of graph nodes, wherein the first set of keywords corresponds one-to-one with the second set of graph nodes.

[0102] Optionally, in this embodiment, the first set of keywords may be stored in a preset server or database, or the first set of keywords may be obtained by performing a network search based on the keywords.

[0103] Optionally, in this embodiment, the keywords mentioned above may include, but are not limited to, keywords corresponding to the application scenario. Taking audio recommendation as an example, if the keyword is a song title, the associated keywords may include, but are not limited to, the singer, genre, bpm, instrument, rhythm, release date, various tags, OST (original soundtrack of a movie), etc. If the keyword is a singer title, the associated keywords may include, but are not limited to, singer type, such as "male or female singer, group, band", date of birth, country / region, genre, awards received, career, etc.

[0104] Optionally, in this embodiment, it can be done by means of, for example Figure 6 The above-mentioned target knowledge graph is constructed in the manner shown. This process may include the following steps:

[0105] S602 uses knowledge extraction technology to extract knowledge elements such as entities, relationships, and attributes from semi-structured, unstructured, and third-party structured databases.

[0106] S604 represents knowledge elements through effective means, facilitating further processing and use. The comprehensive vectors formed by distributed knowledge representations are of great significance for the construction, reasoning, fusion, and application of knowledge bases.

[0107] S606, through knowledge fusion, can eliminate ambiguity between entities, relations, attributes and other referential terms and factual objects, forming a high-quality knowledge base.

[0108] S608, through knowledge processing, further mines implicit knowledge on the basis of the existing knowledge base, constructs new ontology, and completes relationships, thereby enriching and expanding the knowledge base.

[0109] S610, through knowledge assessment, can quantify the credibility of knowledge, retain those with higher confidence and discard those with lower confidence, effectively ensuring the quality of knowledge.

[0110] This embodiment provides users with visualized keyword information, enabling them to select keywords and determine the necessary graph nodes based on actual circumstances.

[0111] In an optional embodiment, obtaining a set of keywords that are related to the keywords on the second graph node from the first information set includes: obtaining a first set of keywords that are related to the keywords on the second graph node from the first information set; sorting the first set of keywords according to their popularity to obtain a second set of keywords; and selecting the top N keywords in popularity from the second set of keywords to obtain a set of keywords, where N is a natural number.

[0112] Optionally, in this embodiment, the first group of keywords can be sorted based on popularity information to obtain the second group of keywords. The popularity can be determined by factors including but not limited to search index and click-through rate. The second group of keywords can be determined based on the topN algorithm. By setting a threshold N, the top N keywords are selected from the second group of keywords as keywords corresponding to the graph nodes.

[0113] For example, with Figure 3 For example, the relevant song keywords for singer A include song A, song B, song C, etc., which are sorted by popularity as "song A", "song B", and "song C". If N is set to 2, the knowledge graph nodes corresponding to the keywords "song A" and "song B" will be displayed, but the knowledge graph node corresponding to "song C" will not be displayed. If N is set to 3, the knowledge graph nodes corresponding to the keywords "song A", "song B", and "song C" will be displayed.

[0114] This embodiment enables filtering based on the current popularity of information, thereby providing users with keywords for knowledge graph nodes with high popularity, facilitating subsequent selection by users and optimizing the user experience.

[0115] In an optional embodiment, displaying the newly added second set of graph nodes on the first interactive interface includes: when the second set of graph nodes includes a third graph node and a fourth graph node, displaying the third graph node on the first interactive interface using a first display method and displaying the fourth graph node using a second display method, wherein the keywords on the third graph node and the keywords on the fourth graph node are keywords of different types.

[0116] Optionally, in this embodiment, the display can be based on one or more combinations of different shapes, colors, fonts, etc., for example, Figure 3 As shown, the graph nodes used to represent songs are displayed using a first display method, which is a circle, and the graph nodes used to represent singer names are displayed using a second display method, which is a square.

[0117] This embodiment displays different types of graph nodes based on different display methods, and displays the same type of graph nodes based on the same display method. This can more clearly show the graph nodes and their corresponding types to the user, improve the user's efficiency, and optimize the user experience.

[0118] In an optional embodiment, the method further includes: in response to a first interactive operation, displaying a target node on a first interactive interface, wherein the target node is displayed as an adjacent node of a second graph node, the target node is used to display a third set of keywords, the third set of keywords is associated with the keywords on the second graph node, and the third set of keywords is different from the keywords on the second graph node.

[0119] Optionally, in this embodiment, the third set of keywords may include, but is not limited to, keywords that are different from the keywords on the second set of graph nodes, for example, such as Figure 7 As shown, the third set of keywords 704 may include, but is not limited to, "more", "other", etc. The target node 702 may be configured to display other content of the same or different types after obtaining the interactive operation. The content may include media information, keywords, links, etc., and may be displayed as keywords that do not appear in the second set of graph nodes after being sorted based on popularity.

[0120] In this embodiment, target nodes are used to display keywords that are not directly displayed in the graph nodes. This provides users with richer and more diverse choices when the keywords corresponding to the second set of graph nodes are not the keywords the user needs. This facilitates better service based on user needs, optimizes the user experience, and improves user efficiency.

[0121] In an optional embodiment, the method further includes: obtaining a third interactive operation performed on the target node; displaying a third set of keywords in response to the third interactive operation; and, if a fourth set of keywords in the third set of keywords is selected, displaying a third set of graph nodes on the first interactive interface and displaying the fourth set of keywords in the corresponding graph nodes in the third set of graph nodes, wherein the third set of graph nodes corresponds one-to-one with the fourth set of keywords, and the third set of graph nodes is displayed as an adjacent node of the second graph node.

[0122] Optionally, in this embodiment, the third group of graph nodes may include, but is not limited to, the graph nodes corresponding to the fourth group of keywords. The fourth group of keywords can be selected from the third group of keywords by performing the third interactive operation on the target node.

[0123] Optionally, in this embodiment, a third interactive operation can be performed on the third set of keywords of the target node to trigger a drop-down menu to display the third set of keywords, and then an interactive operation can be performed to select a fourth set of keywords from the third set of keywords, for example, such as... Figure 7 As shown, clicking "More" triggers a drop-down menu, and clicking "Movies" selects the fourth set of keywords as "movies." Finally, the graph nodes associated with the keyword "movies" are displayed as the third set of graph nodes mentioned above.

[0124] The above is merely an example, and this embodiment does not impose any specific limitations.

[0125] This embodiment enables users to have a wider range of choices when the keywords corresponding to the second set of graph nodes are not the keywords they need. This facilitates services that meet user needs, optimizes the user experience, and improves user efficiency.

[0126] In an optional embodiment, the method further includes: if the third set of graph nodes is displayed on the first interactive interface, canceling the display of the second set of graph nodes on the first interactive interface.

[0127] In an optional embodiment, the method further includes: when the newly added second set of graph nodes is displayed on the first interactive interface, displaying a first set of media information matching the keywords on the second graph nodes on the second interactive interface; or, when the newly added second set of graph nodes is displayed on the first interactive interface, displaying a second set of media information matching the keywords on the second graph nodes and the keywords on some or all of the graph nodes in the second set of graph nodes on the second interactive interface; or, when the newly added second set of graph nodes is displayed on the first interactive interface, displaying a third set of media information matching the keywords on some or all of the graph nodes in the second set of graph nodes on the second interactive interface.

[0128] Optionally, in this embodiment, the media information corresponding to the keyword can be directly displayed in the graph node. For example, if the keyword is the singer's name, the graph node corresponding to the keyword will display the singer's photo and the singer's name.

[0129] Optionally, in this embodiment, when the newly added second set of graph nodes is displayed on the first interactive interface, the media information corresponding to the keyword can be played directly. For example, if the keyword is a song title, the corresponding song can be played directly.

[0130] Optionally, in this embodiment, the aforementioned media information may also include, but is not limited to, setting different display animation effects according to different graph nodes, and displaying the additional data of the keyword corresponding to the graph node as media information, such as the browsing popularity of the keyword, whether the keyword belongs to recent hot data, etc. Taking the keyword as belonging to recent hot data as an example, the graph node corresponding to the keyword belonging to recent hot data can be displayed in the form of being surrounded by "flame" effects to indicate that the keyword belongs to recent hot data.

[0131] This embodiment allows for direct content recommendations to users after they select a graph node, enabling them to obtain media information corresponding to the keywords associated with the graph node more quickly and effectively.

[0132] In an optional embodiment, the method further includes: before obtaining the first interactive operation performed on the second graph node on the first interactive interface, displaying a fourth set of media information on the second interactive interface, wherein the fourth set of media information matches the keywords on the fourth set of graph nodes that have been selected in the target knowledge graph; if the newly added second set of graph nodes is displayed on the first interactive interface, the method further includes: updating the fourth set of media information displayed on the second interactive interface to a fifth set of media information, wherein the fifth set of media information matches the keywords on the fifth set of graph nodes that have been selected in the target knowledge graph, and the fifth set of graph nodes includes the second graph node.

[0133] Optionally, in this embodiment, the media information can be updated according to the new interactive operation, and the displayed media information can be updated to the media information corresponding to the newly selected graph node.
