It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
In order to solve the problem that the content searched by the existing search function module provided by each APP or site for a user is not comprehensive enough, the embodiment of the specification provides a content searching method based on a block chain. The execution subject of the method provided in the embodiments of the present disclosure may be, but is not limited to, a target search server and the like, and may be configured to execute at least one of the method apparatuses provided in the embodiments of the present disclosure.
For convenience of description, an embodiment of the method will be described below taking an execution body of the method as an example of a target search server capable of executing the method. It will be appreciated that the subject matter of the method is merely an exemplary illustration of a content crawling platform and should not be construed as limiting the method.
Specifically, an implementation flow diagram of a content searching method based on a blockchain provided in one or more embodiments of the present disclosure is shown in fig. 1, and includes:
step 110, receiving a search request of a user, wherein the search request carries a search keyword of the user;
optionally, after obtaining the search keyword of the user, in order to provide the content with a higher matching degree with the search keyword for the user so as to improve the accuracy of the search, and improve the content search experience of the user, before obtaining the content list matched with the search keyword of the user based on the search keyword of the user, the embodiment of the present disclosure further includes:
acquiring a content search record from a blockchain;
the association degree between the search keywords in the content search records and the corresponding content is greater than or equal to a preset threshold value, and the content search records are uploaded to the blockchain by other search servers.
It should be appreciated that in order to make the content search in the target search server more comprehensive and accurate, the target search server may obtain content search records from the blockchain that may be obtained by other search servers based on the user searching within their corresponding APP or site and uploaded to the blockchain by other search servers periodically. In order to update the content search record in the target search server in time, the target search server may acquire the content search record from the blockchain every preset time period. The content search record may include a plurality of search keywords and content matching the plurality of search keywords, and a degree of association between each search keyword and the corresponding content.
The association degree between each search keyword and the corresponding content can be calculated based on the behavior operation record of the user on the content corresponding to each search keyword. The behavioral operation record of the user on the content corresponding to each search keyword may include: clicking behavior, copying behavior, sharing behavior, browsing behavior and browsing duration of the content corresponding to each search keyword by the user. The association degree between each search keyword and the corresponding content is used for ranking the content corresponding to each search keyword, so that the content ranked in the first few positions, namely the content with higher association degree, is displayed to the user, and the search accuracy is improved.
Generally, the format of the content includes one or more of text, image, video and audio, which causes the capacity of different content to be different, the content containing text only tends to be smaller, and if the content includes image, video or audio, the capacity of such content is larger. In order to reduce the amount of storage space occupied by such content uploaded to the blockchain, in the embodiment of the present disclosure, the content in the content search record obtained by the target search server from the blockchain is typically a link corresponding to the content.
Step 120, based on the search keyword of the user, obtaining a content list matched with the search keyword of the user;
it should be understood that a content search library should be maintained in the target search server, where the content search library includes a plurality of search keywords and contents corresponding to the plurality of search keywords, and then, based on the search keywords of the user, a content list matching the search keywords of the user is obtained, and in particular, the content list matching the search keywords of the user may be obtained in the content search library in the target search server. In order to provide a user with a more complete search result, the content search library includes, in addition to the search keywords and corresponding content existing locally at the target search server, the search keywords and corresponding content uploaded by other search servers and downloaded from the blockchain by the target search server.
And 130, displaying at least one target content with the highest association degree with the search keywords of the user in the content list to the user, wherein part or all of the content in the content list is obtained from the blockchain.
The content in the content list may be ranked based on the relevance between the content in the content list and the search keyword of the user, for example, the content in the content list may be ranked in order from high to low, and the top-ranked content in the content list may be displayed to the user, for example, the top-ranked content in the content list may be displayed to the user.
Optionally, in order to provide a more accurate search result for the user, the embodiment of the specification may further obtain a behavior operation record of the user on the search result, and calculate the association degree between the search keyword and the corresponding content based on the behavior operation record by pre-configuring the specified intelligent contract in the blockchain, so that the next time the user inputs the same search keyword, the user may display the content with higher association degree, thereby improving the search experience of the user. Specifically, after at least one target content in the content list, which is ranked in front of the association degree of the search keyword of the user, is presented to the user, the method further comprises:
acquiring a behavior operation record of a user on at least one target content;
uploading a transaction carrying a content search record of a user to a blockchain to trigger a specified intelligent contract in the blockchain to determine the association degree of a search keyword of the user and at least one target content based on a behavior operation record;
the content search records of the user comprise search keywords of the user, links of at least one target content and behavior operation records of the user on a plurality of target contents.
Optionally, the behavior operation record of the user on the at least one target content includes at least one of the following:
a user's copying behavior of at least one target content;
a browsing duration of the user for at least one target content;
a sharing behavior of the user on the at least one target content;
clicking actions of the user on at least one target content.
It should be understood that, because the storage space in the blockchain is limited, in order to facilitate storage of the behavior operation records of the user, in this embodiment of the present disclosure, the identifiers corresponding to different operation behaviors may be preset, for example, the identifier of the copy behavior of the user on at least one target content may be set to be C, the identifier of the browsing duration of the user on at least one target content may be set to be r_time (the time may be a specific duration, the unit may be seconds), the identifier of the sharing behavior of the user on at least one target content may be S, and the identifier of the click behavior of the user on at least one target content may be set to be D.
To facilitate determining the association of a user's search keyword with at least one target content based on behavioral records, embodiments of the present disclosure may pre-configure a specified smart contract in the blockchain that triggers when a user's behavioral records are uploaded into the blockchain, or that triggers when multiple users ' behavioral records of the same search keyword for one content are uploaded into the blockchain. More specifically, the score corresponding to each operation behavior of the user and the corresponding weight may be preset in the specified smart contract, so that the specified smart contract calculates the degree of association between the search keyword and each corresponding content based on the score corresponding to each operation behavior in the behavior operation record of the user and the corresponding weight.
Alternatively, since the collaboration agreement may or may not be reached online between different search servers, embodiments of the present description may set download rights for content search records uploaded into the blockchain for such a case. Specifically, the content search record of the user carries a content sharing identifier list, and the content sharing identifier in the content sharing identifier list is used for indicating that the permission of downloading the content search record of the user is provided. That is, when the target search server downloads content search records uploaded by other search servers from the blockchain, only the content search records carrying the target search server identification can be downloaded.
Optionally, in the case that the download authority is set, the method provided by the embodiment of the present specification further includes:

Optionally, in order to ensure that the association degree between each search keyword in the target search server and the corresponding content is kept at a high level, the embodiments of the present disclosure provide two ways to obtain the content search record carrying the identifier of the target search server from the blockchain: in the first mode, a timer is locally set at a target search server, so that the target search server acquires a content search record carrying an identifier of the target search server from a blockchain every preset time period; in a second way, trigger conditions are configured in the specified intelligent contracts in the blockchain such that the specified intelligent contracts in the blockchain are triggered when other search servers upload content search records to the blockchain that carry the identity of the target search server.
Specifically, obtaining a content search record carrying an identifier of a target search server from a blockchain includes:
acquiring a content search record carrying an identifier of a target search server from a blockchain every preset time period; or alternatively
And acquiring a content search record carrying the identification of the target search server from the blockchain through a specified intelligent contract in the blockchain.
Optionally, the embodiment of the specification may further calculate a relevance between the search keyword of the user and at least one target content through the target search server, and upload the relevance to the blockchain after calculation. After presenting the at least one target content in the content list that is top-ranked with respect to the search keyword to the user, the method further comprises:
acquiring a behavior operation record of a user on at least one target content;
determining the association degree of the search keywords of the user and at least one target content based on the behavior operation record;
uploading a transaction carrying the association degree of the search keyword of the user and at least one target content to the blockchain through a specified intelligent contract in the blockchain;
the content search records of the user comprise search keywords of the user, links of at least one target content and behavior operation records of the user on a plurality of target contents.

S22, the B server downloads content search records uploaded by other servers from the blockchain every preset time period, wherein the content search records carry a plurality of search keywords and content links corresponding to the search keywords, and also carry the association degree between the search keywords and the corresponding content links;
s23, the user searches content in the APP or the browser corresponding to the B server, so that the APP or the browser corresponding to the B server sends a search request to the B server, wherein the search request comprises search keywords of the user;
s24, B service searches a content list matched with the search keywords of the user based on the local content search record and the content search record downloaded from the blockchain, and displays the content with higher association degree ranking with the search keywords of the user in the content list to the user through an APP or a browser;
s25, the APP or the browser acquires behavior operation records of the displayed content, such as records of clicking, sharing, copying, browsing duration and the like, and uploads user information, search keywords of the user, content corresponding to the search keywords of the user and behavior operation records of the content corresponding to the search keywords of the user into a blockchain;
s26, triggering specified intelligent contract calculation in the blockchain and updating the association degree between the search keywords of the user and the corresponding content based on the behavior operation records of the content corresponding to the search keywords of the user uploaded to the blockchain;
in order to improve the accuracy of the association degree, when the behavior operation records of the content corresponding to the keyword uploaded to the blockchain reach a preset number, namely, after the behavior operation records of the content corresponding to the same keyword by a preset number of users are uploaded to the blockchain, the association degree between the keyword and the corresponding content can be calculated and updated by triggering the appointed intelligent contract in the blockchain.
And S27, the A server downloads content search records uploaded by other servers from the blockchain, wherein the content search records comprise a plurality of keywords, contents corresponding to the keywords and association degrees between the keywords and the corresponding contents.
