Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and more specifically to a resource retrieval method, apparatus, device, medium and program product. Background Art

[0002] When teams in an enterprise or organization collaborate, they need to use a knowledge base system to share and collaboratively edit information such as knowledge documents, project progress, and meeting minutes. When the knowledge base is used to a certain extent and the knowledge document content has reached a considerable scale, members of different teams in the knowledge base need to perform full-text searches on the document content under their permissions when using the knowledge base. At present, the method of full-text search under permission control generally takes documents as units, authorizes documents to users or user-related groups (such as user groups, roles, organizations, etc.), and establishes query indexes for authorized objects.

[0056] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0057] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0058] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0059] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0060] When teams in an enterprise or organization collaborate, they need to use a resource library system to share and collaboratively edit knowledge documents, project progress, meeting minutes, and other resources. When the resource library is used to a certain extent and the resources have reached a considerable scale, members of different teams in the resource library need to perform full-text searches on the resources under their permissions when using the resource library.

[0061] Currently, the method for full-text search under authority control generally uses resources as units, authorizes resources to users or user-related groups (such as user groups, roles, organizations, etc.), and establishes a query index for the authorized objects.

[0062] However, there are at least the following problems in the related technology: resources are directly authorized to users or user-related groups and a full-text search index is established for the authorization information. On the one hand, the index will be frequently updated as the authorization information changes, thereby consuming a large amount of memory and input and output interface resources. On the other hand, when there are more authorized users, the number of bits in the index query conditions will increase accordingly, generating lengthy Boolean filter statements during retrieval, ultimately resulting in reduced full-text retrieval performance and low retrieval efficiency.

[0063] In view of this, the present disclosure aims at the above technical problems by attributing resources to spaces, authorizing space permissions to users, forming a space permission list corresponding to the user, and using the space permission list to filter out the space to which the user has permissions as the target space according to the preset matching rules. Since resources belong to spaces, determining the target space means determining all the resources to be retrieved to which the user has permissions; finally, the target resource is determined from the resources to be retrieved according to the search keywords. The present disclosure attributes resources to spaces and authorizes space permissions to users, thereby separating resources from users, reducing the complexity of search query conditions, and at the same time, the association relationship of structured data between users and resources is handled by a relational database, saving memory resource consumption and helping to improve search efficiency.

[0064] Specifically, an embodiment of the present disclosure provides a resource retrieval method, comprising: in response to a resource retrieval request, parsing user information and retrieval keyword information in the above resource retrieval request; obtaining a space permission list corresponding to the above user information based on the above user information, wherein the user corresponding to the above user information has the authority to access the space in the above space permission list; filtering a target space corresponding to the above user information from multiple spaces according to preset matching rules based on the above space permission list, wherein the above target space includes resources to be retrieved; and determining the target resource from the above resources to be retrieved based on the above retrieval keyword information.

Accordingly, the resource retrieval device provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the terminal devices 101, 102, 103 and / or the server 105.

[0074] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0075] The following will be based on Figure 1The scene described by Figure 2 to Figure 6 The resource retrieval method of the disclosed embodiment is described in detail.

[0076] Figure 2 The flowchart of the resource retrieval method according to the embodiment of the present disclosure is schematically shown.

[0077] like Figure 2 As shown, the resource retrieval method of this embodiment includes operations S210 to S240, and the resource retrieval method can be executed by a server.

[0078] In operation S210, in response to a resource search request, user information and search keyword information in the resource search request are parsed.

[0079] According to an embodiment of the present disclosure, user information may include, for example, information that can determine the user's space permissions. User information may include information such as the user group, role, or organization to which the user belongs. For example, information such as the user's name, user number, user position, and user permissions.

[0080] According to an embodiment of the present disclosure, the search keyword information may include, for example, a search keyword input by a user, which is used to search for resources corresponding to the keyword.

[0081] According to an embodiment of the present disclosure, when performing resource retrieval, the user logs in to the retrieval system on the login page, enters the retrieval keyword in the retrieval input box, and clicks the retrieval button to send a resource retrieval request, wherein the resource retrieval request includes user information and the retrieval keyword information entered by the user. In response to the resource retrieval request, the user information and the retrieval keyword information in the resource retrieval request are parsed to obtain the user information and the retrieval keyword information.

[0082] In operation S220, a space permission list corresponding to the user information is acquired according to the user information, wherein the user corresponding to the user information has the permission to access the space in the space permission list.

[0083] According to an embodiment of the present disclosure, the space to which the user has access rights may be determined based on the user information, and the space permission list may be obtained based on the user information.

[0084] According to an embodiment of the present disclosure, each space has a corresponding space code, and the space permission list includes space codes corresponding to spaces to which the user has access rights.

[0085] According to an embodiment of the present disclosure, the space code is a unique code of the space, which is used to identify and authorize the space. The space code may include English letters, numbers, etc. For example, the space code may be spaceA1, spaceB2.

[0086] In operation S230, a target space corresponding to the user information is screened from a plurality of spaces according to the space permission list and a preset matching rule, wherein the target space includes resources to be retrieved.

[0087] According to an embodiment of the present disclosure, the preset matching rule may include, for example, matching the space codes of multiple spaces with each space code in the space permission list in sequence, and using the successfully matched space as the target space. The target space is the space corresponding to the space code in the space permission list.

[0088] According to the embodiments of the present disclosure, resources are attributed to spaces, and resources are bound to corresponding spaces. When a user has access rights to a space, he or she also owns all resources in the space.

[0089] For example, among multiple spaces, a user has access rights to the following spaces: space with space code A, space with space code B, space with space code C, space with space code D, and space with space code E, then the space permission list corresponding to the user includes: A, B, C, D, and E. When determining the target space, the space codes of the multiple spaces are matched with A, B, C, D, and E in sequence, and the space with space code A, space with space code B, space with space code C, space with space code D, and space with space code E are screened out from the multiple spaces, that is, the target space corresponding to the user.

[0090] In operation S240, a target resource is determined from the resources to be searched according to the search keyword information.

[0091] According to the embodiment of the present disclosure, after the target space is determined, the resources in the target space are all resources to be searched, and a full-text search is performed from the resources to be searched according to the search keyword information, and the search results are rendered and displayed.

[0092] According to an embodiment of the present disclosure, by responding to a resource retrieval request, the user information and retrieval keyword information in the resource retrieval request are parsed; then, a space permission list corresponding to the user information is obtained according to the user information, wherein the user corresponding to the user information has the permission to access the space in the space permission list; then, according to the space permission list, a target space corresponding to the user information is screened from multiple spaces according to a preset matching rule, wherein the target space includes the resources to be retrieved; finally, according to the retrieval keyword information, the target resource is determined from the resources to be retrieved. The present disclosure attributes resources to spaces, and authorizes space permissions to users, thereby separating resources from users, reducing the complexity of retrieval query conditions, and at the same time, the association relationship of structured data between users and resources is handled by a relational database, saving memory resource consumption and helping to improve retrieval efficiency.

[0093] According to an embodiment of the present disclosure, the above-mentioned resource retrieval method also includes: converging the above-mentioned space permission list according to preset convergence rules to obtain an actual permission list and a converged permission list, wherein the above-mentioned actual permission list includes space permissions that have not been converged in the above-mentioned space permission list, and the above-mentioned converged permission list is the space permissions formed after the spaces in the above-mentioned space permission list are converged; wherein, the above-mentioned screening of the target space corresponding to the above-mentioned user information from multiple spaces according to the preset matching rules according to the above-mentioned space permission list includes: screening the above-mentioned target space corresponding to the above-mentioned user information from multiple spaces according to the above-mentioned actual permission list and the above-mentioned converged permission list according to the above-mentioned preset matching rules.

[0094] According to an embodiment of the present disclosure, a plurality of spaces form a space tree, and the space tree includes one or more layers to form a corresponding space hierarchical structure.

[0095] According to an embodiment of the present disclosure, the preset convergence rule may include, for example, when all child nodes belonging to the same parent node have spatial authority, converging the authority to the spatial encoding of the parent node, and filtering the spatial encoding of the child node from the spatial authority list.

[0096] For example, in the spatial hierarchy, the spatial code of one of the parent nodes is A, and the spatial codes of the two child nodes belonging to the parent node are B and C respectively. When the user has the spatial permissions of B and C, the user's permissions are converged to the parent node A, the spatial code A of the parent node is stored in the converged permission list, and the spatial codes B and C are filtered out from the spatial permission list to obtain the actual permission list.

[0097] According to an embodiment of the present disclosure, the above-mentioned space permission list can be converged multiple times according to preset convergence rules until there are no child nodes that can be converged.

[0098] According to an embodiment of the present disclosure, the above-mentioned spatial permission list is converged according to a preset convergence rule to obtain an actual permission list and a converged permission list, including: analyzing the above-mentioned spatial permission list according to the spatial hierarchical structure to obtain an analysis result; when the above-mentioned analysis result indicates that all child nodes belonging to the same parent node have spatial permissions, the spatial coding of the above-mentioned parent node is stored in the above-mentioned converged permission list to obtain the above-mentioned converged permission list; the spatial coding of the above-mentioned child node is filtered out from the above-mentioned spatial permission list to obtain the above-mentioned actual permission list.

[0099] Figure 3 A schematic diagram schematically shows the convergence of the space permission list according to an embodiment of the present disclosure.

[0100] like Figure 3As shown, the spatial permission list corresponding to the user includes spatial codes D, H, C, J, and K, which are converged twice in sequence, including an initial spatial hierarchy structure 310, a spatial hierarchy structure 320 after the first convergence, and a spatial hierarchy structure 330 after the second convergence.

[0101] A convergence includes analyzing the spatial permission list according to the initial spatial hierarchical structure 310, and the analysis results include that the two child nodes J and K belonging to N both have spatial permissions, and the two child nodes D and H belonging to B both have spatial permissions; then the spatial codes of J and K are filtered out from the spatial permission list, and the spatial code of N is stored in the converged permission list, the spatial codes of D and H are filtered out from the spatial permission list, and the spatial code of B is stored in the converged permission list, to obtain an actual permission list and a converged permission list after a convergence, wherein the actual permission list after a convergence includes the spatial code C, and the converged permission list after a convergence includes the spatial codes N and B.

[0102] The initial spatial hierarchical structure after the first convergence forms the spatial hierarchical structure after the first convergence 320. The second convergence is performed on the basis of the spatial hierarchical structure 320 after the first convergence.

[0103] The secondary convergence includes analyzing the actual permission list C and the converged permission lists N and B after the first convergence according to the spatial hierarchical structure 320 after the first convergence. The analysis result includes that the two child nodes B and C of A both have spatial permissions, then the spatial code B is filtered out from the converged permission list, the spatial code C is filtered out from the actual permission list, and the spatial code of A is stored in the converged permission list to obtain the actual permission list and the converged permission list after the secondary convergence, wherein the actual permission list after the secondary convergence is empty, and the converged permission list after the secondary convergence includes the spatial codes N and A.

[0104] The spatial hierarchical structure 320 after the first convergence forms the spatial hierarchical structure 330 after the second convergence. After the second convergence, there is no child node that can be converged, indicating that the convergence is complete. The final convergence result is that the actual permission list is empty, and the converged permission list includes the spatial codes N and A.

[0105] According to an embodiment of the present disclosure, the above-mentioned resource retrieval method also includes: determining the spatial path corresponding to the space according to the spatial hierarchical structure and the spatial coding; using the above-mentioned spatial path as the permission index corresponding to the resources in the above-mentioned space; wherein, the above-mentioned filtering the target space corresponding to the above-mentioned user information according to the preset matching rules based on the above-mentioned actual permission list and the above-mentioned converged permission list includes: filtering the above-mentioned target space corresponding to the above-mentioned user information according to the above-mentioned preset matching rules based on the above-mentioned actual permission list, the above-mentioned converged permission list and the above-mentioned permission index.

[0106] According to an embodiment of the present disclosure, a spatial path represents a spatial location, and hierarchical relationships can be quickly found. A spatial path is formed by splicing the spatial coding intervals through which the space passes using underscores. For example, Figure 3 In the initial spatial hierarchical structure, the spatial path for space K can be expressed as: XGNK.

[0107] According to an embodiment of the present disclosure, when resources are created in a space, the space path is used as a permission index corresponding to the resources in the space, and the permission index is used to filter out a target space when filtering according to a preset matching rule.

[0108] According to an embodiment of the present disclosure, the above-mentioned screening of the above-mentioned target space corresponding to the above-mentioned user information according to the above-mentioned actual permission list, the above-mentioned converged permission list and the above-mentioned permission index according to the above-mentioned preset matching rules includes: generating a path list according to the space encoding in the above-mentioned permission index; matching the above-mentioned path list with the above-mentioned actual permission list and the above-mentioned converged permission list according to the above-mentioned preset matching rules to obtain a matching result; in a case where the above-mentioned matching result indicates a successful match, the space corresponding to the above-mentioned path list is used as the above-mentioned target space.

[0109] According to an embodiment of the present disclosure, the path list is obtained by arranging the spatial codes in the authority index in order.

[0110] According to an embodiment of the present disclosure, the actual permission list and the converged permission list are matched with the path list according to the above preset matching rules to obtain a matching result. If the match is successful, the space corresponding to the path list is used as the target space.

[0111] For example, to match space K with permission index XGNK, first, generate a path list corresponding to the permission index: X, G, N, K; then, match the path list (X, G, N, K) according to the preset matching rules based on the actual permission list and the converged permission list to obtain a matching result. If the match is successful, the space K corresponding to the path list is used as the target space, that is, space K is the target space. Users can retrieve resources in space K. If the match fails, it means that the user does not have access rights to space K and cannot retrieve resources in space K.

[0112] According to an embodiment of the present disclosure, the above-mentioned path list is matched according to the above-mentioned preset matching rules based on the above-mentioned actual authority list and the above-mentioned convergence authority list to obtain a matching result; when the above-mentioned matching result indicates a successful match, the space corresponding to the above-mentioned path list is used as the above-mentioned target space, including: matching the space coding in the above-mentioned path list with the space coding in the above-mentioned actual authority list to obtain a first matching result; when the above-mentioned first matching result indicates a failed match, matching the space coding in the above-mentioned path list with the space coding in the above-mentioned convergence authority list to obtain a second matching result; when the above-mentioned second matching result indicates a successful match, the space corresponding to the above-mentioned path list is used as the above-mentioned target space.

[0115] According to an embodiment of the present disclosure, in a case where the first matching result represents that the spatial coding in the path list does not have the same spatial coding as the spatial coding in the actual authority list, for example, the spatial coding in the path list (such as X, G, N, K) does not have the same spatial coding as the spatial coding in the actual authority list (such as Y), indicating that the first matching result fails to match.

[0118] According to an embodiment of the present disclosure, when the second matching result indicates a successful match, taking the space corresponding to the path list as the target space includes: when the second matching result indicates that the space coding of the convergence authority list has the same space coding as the space coding in the path list, and the convergence authority list does not contain the last space coding in the path list, taking the space corresponding to the path list as the target space.

[0119] According to an embodiment of the present disclosure, when the spatial coding of the convergence authority list in the second matching result table is the same as the spatial coding in the path list, and the convergence authority list does not contain the last spatial coding in the path list, for example, the spatial coding of the convergence authority list (such as N) and the spatial coding in the path list (such as X, G, N, K) have the same spatial coding N, and the convergence authority list does not contain the last spatial coding in the path list (such as K), it means that the space corresponding to the path list is the target space.

[0121] According to an embodiment of the present disclosure, when the second matching result indicates that the spatial coding in the convergence authority list does not have the same spatial coding as the spatial coding in the path list, the matching ends, and the space corresponding to the path list is not the target space.

[0122] Figure 4 The flowchart of screening the target space according to the preset matching rules is schematically shown.

[0123] like Figure 4 As shown, the method includes operations S401 to S407.

[0124] In operation S401, an actual authority list, a converged authority list, and a path list are acquired.

[0125] In operation S402, it is determined whether the spatial coding in the path list is identical to the spatial coding in the actual authority list. If it is determined that the spatial coding in the path list is not identical to the spatial coding in the actual authority list, operation S403 is performed; if it is determined that the spatial coding in the path list is identical to the spatial coding in the actual authority list, operation S405 is performed.

[0126] In operation S403, it is determined whether the spatial coding in the path list and the spatial coding in the convergence authority list have the same spatial coding. If it is determined that the spatial coding in the path list and the spatial coding in the convergence authority list have the same spatial coding, operation S404 is performed; if it is determined that the spatial coding in the path list and the spatial coding in the convergence authority list do not have the same spatial coding, operation S406 is performed.

If it is determined that the convergence right list does not include the last space code in the path list, operation S405 is performed.

[0129] In operation S406 , it is determined that the space corresponding to the path list is not the target space.

[0130] In operation S407, the matching ends.

[0131] It should be noted that Figure 4 The process of filtering the target space according to the preset matching rules is only the process of matching one of the spaces. In the process of determining the target space, the permission index corresponding to each space needs to be matched as follows Figure 4 The screening process in .

[0132] According to the embodiments of the present disclosure, by rewriting the Lucene query method and screening the target space by using preset matching rules, efficient retrieval of the target space is achieved.

[0133] Figure 5 The following schematically shows an architecture diagram of a retrieval device according to an embodiment of the present disclosure.

[0134] like Figure 5 As shown, the search device 500 includes a space management module 510 , a resource management module 520 , a permission query module 530 and a permission search module 540 .

[0135] The space management module 510 is mainly responsible for adding, deleting, modifying and checking spaces and for authorizing spaces. Spaces can be authorized to users, roles, user groups and organizations. When authorizing roles, user groups and organizations, users are associated with roles, user groups and organizations. When creating a space, the space code is combined with a special identifier (such as an underscore) according to the spatial hierarchy of the current space to generate a space path. The generated space path is managed by the resource management module.

[0136] The resource management module 520 is used to add, delete, modify and query resources under the space, and bind resources to the space through the space management module. When adding new resources, the domain of the initial resource (such as resource name, creation time, creator, resource content, etc.) is created, and the space domain is assigned as the space path of the current space, and a search index is generated according to the type of different domains.

[0137] The permission query module 530 is used to query the space authorized by the current user from the space management module according to the user information, obtain the space permission list, and perform convergence and compression processing on the space permission list to flatten the space permission list, generate the user's actual permission list and converged permission list, and improve the efficiency of subsequent query creation.

[0138] The authority search module 540 is used to obtain the actual authority list and the converged authority list from the authority query module 530, filter the authority index, and select the target space. It can also query the resources in the target space from the resource management center according to keywords, perform full-text search, and output the target resources.

[0139] Figure 6 The following schematically shows a flow chart of a resource retrieval method according to another embodiment of the present disclosure.

[0140] like Figure 6 As shown, the method includes operations S601 to S613.

[0141] In operation S601, a space is created in a space management module, and a space code, such as K, is input.

[0142] In operation S602, a spatial path, for example, _X_G_N_K, is automatically generated according to the spatial hierarchical structure.

[0143] In operation S603, the space type is set, wherein the space type includes an open space and a permission space. The open space does not perform permission control, while the permission space requires permission control.

[0144] In operation S604, authorization operation is performed on the permission space, and the permission space can be authorized to users, roles, user groups, and organizations.

[0145] In operation S605, a space is selected in the resource management module, resources are created in the selected space, and the resources are bound to the space, and the space path of the space is used as the permission index of the resource, such as _X_G_N_K.

[0146] In operation S606, the authority query module responds to the resource search request and parses the user information and search keyword information in the resource search request.

[0147] In operation S607, a space permission list corresponding to the user information is obtained from the space management module according to the user information.

[0148] In operation S608, the space permission list is analyzed according to the space hierarchy structure to obtain an analysis result.

[0149] In operation S609, when the analysis result indicates that all child nodes belonging to the same parent node have spatial authority, the spatial code of the parent node is stored in a converged authority list to obtain a converged authority list.

[0150] In operation S610, the spatial code of the child node is filtered out from the spatial permission list to obtain an actual permission list.

[0151] In operation S611, the permission indexing module screens a target space corresponding to the user information from multiple spaces according to the converged permission list and the actual permission list according to preset matching rules, wherein the target space includes resources to be retrieved, and the resources to be retrieved are managed by the resource management module.

[0152] In operation S612, a target resource is determined by performing a full-text search from the resources to be searched in the resource management module according to the search keyword information.

[0153] In operation S613, the target resource is output.

[0154] According to the embodiment of the present disclosure, resources are attributed to spaces, authorization operations are performed on spaces, and then the space permission list corresponding to the user is converged, and the converged permission list and the actual permission list are converged; then, the target space corresponding to the user information is screened from multiple spaces according to the preset matching rules based on the actual permission list and the converged permission list. By attributing resources to spaces, authorizing space permissions to users, and converging space permission lists, the complexity of search query conditions is reduced, and at the same time, the association relationship between structured data between users and resources is handed over to the relational database for processing, saving memory resource consumption and helping to improve search efficiency.

[0155] It should be noted that, unless it is explicitly stated that there is a sequence of execution between different operations shown in the flowchart in the embodiments of the present disclosure, or there is a sequence of execution between different operations in technical implementation, otherwise, the execution order of multiple operations may not be prioritized, and multiple operations may also be executed simultaneously.
