Description

Blockchain-based search fair sorting method, device and medium

technical field

The present invention relates to the field of computers, in particular to a method, device and medium for fair sorting of searches based on blockchain.

Background technique

The position of search engine plays a pivotal role in the entire Internet and can be called one of the infrastructures of the Internet. In the entire search engine system, the algorithm for sorting search results is the core algorithm that is related to the user's final search experience.

In the current mainstream search engines, the search ranking mechanism mainly adopts PageRank, HITS and other related algorithms, which is a ranking algorithm based on the analysis of links between web pages, and also considers the following factors: the correlation between web page content and keywords or user search intent degree; timeliness and content quality of web pages; website authority and access speed, etc.

However, the traditional way cannot get rid of two drawbacks:

First, the cheating behavior of the website against the search engine ranking algorithm, that is, SEO or SEM. This practice has resulted in the content of many sites that actually have poor content being ranked ahead of good content.

Second, at present, no matter what kind of algorithm is used, the ranking results of the search engine are ultimately controlled by the search engine service provider.

Detailed ways

This part will describe the specific embodiments of the present invention in detail, and the preferred embodiments of the present invention are shown in the accompanying drawings. Each technical feature and overall technical solution of the invention should not be construed as limiting the protection scope of the invention.

In the description of the present invention, the meaning of several is one or more, the meaning of multiple is two or more, greater than, less than, exceeding, etc. are understood as not including this number, above, below, within, etc. are understood as including this number.

In the description of the present invention, the consecutive numbers on the method steps are for the convenience of review and understanding. In combination with the overall technical solution of the present invention and the logical relationship between the various steps, adjusting the execution order of the steps will not affect the technology of the present invention. The technical effect achieved by the program.

Fig. 1 shows an overall flow chart according to an embodiment of the present invention, the process includes: S100, acquiring several search results of a search engine, distributing the search results to multiple clients in the blockchain, and counting the client's Voting information; S200, save the voting results that meet the set requirements and their corresponding search results into the blockchain, where the voting information includes the voting process and voting results; S300, reorder the search results according to the voting results.

FIG. 2 is a schematic diagram of interaction according to an embodiment of the present invention, and the specific flow of the figure is described as follows:

Users vote for the results that meet their search needs, and the system randomly selects a number of users to confirm their votes. If more than two-thirds of the users vote, the user's voting results are received by the system and recorded in the blockchain, and the system votes Successful users and users who participate in confirmation will be rewarded with blockchain tokens. The voting process and results are transparent and immutable, ensuring its impartiality. Then, the ranking model is updated by using the user voting results as a high weight factor for ranking search results. It mainly includes three stages: the user votes and confirms the search results; the voting process and results are saved on the chain; the search engine periodically synchronizes the voting results from the blockchain and updates the search ranking.

Users vote and confirm search results. In the list of search results, a voting button is set for each search result, and users can vote for the search results that meet their search needs and have the highest quality. A number of users randomly selected by the system will confirm the user's vote. If the majority of users agree with the user's vote, the vote will be deemed successful.

The voting process and results are stored on the chain. This method adopts a blockchain scheme with a dual-chain architecture, that is, the data chain and the token chain are parallel, the data chain is used to store voting data, and the token chain is used to record rewards and transactions to users. The token has actual economic value and can be used as a token for advertisers to place advertisements on the search engine platform.

Reward method for voting users: if the user's vote is confirmed by the random group of users, the user will be rewarded; if not, the user will not be rewarded.

Voting to confirm the user's reward method: if the majority of people think the vote is valid, the valid users will be rewarded, and the users who think the vote is invalid will not be rewarded; conversely, if the majority of people think the vote is invalid, the invalid users will be considered Get rewarded, no reward for users who are considered valid.

The search engine periodically synchronizes the voting results from the blockchain and updates the search ranking. The system calculates the ranking factor by synchronizing the user voting data recorded in the data chain in real time, and regularly updates the ranking model in combination with the traditional ranking factor, thereby improving the final search results.

Users' votes on search results reflect their real search needs and the degree to which search results satisfy their needs. Adding these factors as higher weights to the ranking model can greatly improve the user's search experience and avoid low-level search results. cheating on quality websites. The methods of token incentives and group confirmation also ensure that users will not vote at will.

3 shows a schematic diagram of an overall flow according to an embodiment of the present invention, and this embodiment includes the following flow:

(1) Modify the existing search result list and add a voting button next to each search result.

(2) Build a data chain and a token chain based on the current mature blockchain technology. The data chain adopts the open source "super ledger" scheme; the pass chain is realized based on the development of smart contracts on Ethereum.

(3) Push the voting information of a certain user through the system message to notify a number of randomly selected users for secondary confirmation.

(4) The interface of the data chain is called, and the voting information after the second confirmation is recorded on the data chain.

(5) Call the interface of the token chain, and transfer a number of tokens to the accounts of voting users and users participating in confirmation for incentives.

(6) The synchronization program regularly synchronizes the user's voting data from the data link.

(7) User votes are added to the original search ranking model as a new factor.

(8) Recalculate the ranking score of the search result for a certain query word.

(9) Display the search results to the search user according to the order of the sorting points.

Figure 4 shows a schematic diagram of an apparatus according to an embodiment of the present invention. The device includes a memory 100 and a processor 200, wherein the processor 200 stores a computer program, and the computer program is used for executing: acquiring several search results of a search engine, distributing the search results to multiple clients in the blockchain, Count the voting information of the client; save the voting results that meet the set requirements and their corresponding search results into the blockchain, where the voting information includes the voting process and voting results; reorder the search results according to the voting results. Among them, the memory 100 is used for storing data when the computer program is running.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, and within the scope of knowledge possessed by those of ordinary skill in the technical field, various Variety.
