The invention discloses an information searching method, an information searching device, computer equipment and a storage medium, wherein basic keywords are obtained firstly, then the basic keywords are translated into corresponding translation keywords, then searching is carried out according to the basic keywords and the translation keywords to obtain searching webpages corresponding to the basic keywords, and finally target webpages are screened out from all the searching webpages to be used as searching results based on the jumping probability value between every two searching webpages, so that the multi-language searching of the basic keywords can be realized, the finally obtained searching results can contain multiple languages, the searching breadth is improved, the searching webpages are screened according to the jumping probability value between every two searching webpages to obtain the searching results, the screening of the searching webpages by using relatively complex standards can be realized, and the searching accuracy is improved. The following are detailed below.
Example one
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an information searching method according to an embodiment of the present invention. As shown in fig. 1, the information searching method may include the following operations:
101. and acquiring basic keywords.
In the step 101, the basic keyword may be input by the user, for example, the user may input the english word "Homomorphic encryption" as the basic keyword to be used for the subsequent search. Optionally, the basic keyword input by the user may also include words of multiple languages, for example, words of both chinese and english.
102. And executing preset automatic translation operation on the basic keywords to obtain translation keywords corresponding to the basic keywords.
In step 102, the basic keyword may be automatically translated by a preset translator (e.g., Baidu translation, Google translation, etc.), so that the basic keyword is translated into words of different languages (i.e., translation keyword). After the user inputs the basic keyword, the basic keyword may be set as a keyword I1And marking the language of the basic key words as t1. The user may pre-select the language in which the underlying keyword is to be translated, thereby forming a list of languages { t }1,t2,t3,……,tnAnd then the translator can translate the basic keywords into words of corresponding languages according to a language list set by a user. E.g. t in language list1、t2、t3The English words, the Chinese words and the German words are sequentially 'English', 'Chinese' and 'German' and the basic key words input by the user are 'Homomorphic encryption', the translator translates the 'Homomorphic encryption' into the 'Homomorphic encryption' of the Chinese words and the 'Homorphic Verschl ü sselung' of the DE words and respectively sets the 'Homomorphic encryption' of the Chinese words and the 'Homorphic encryption' of the DE words as the key words I2And a keyword I3。
103. And executing preset search operation according to the basic keywords and the translation keywords to obtain a search webpage corresponding to the basic keywords.
In step 103, after obtaining the basic keyword and the translation keyword, the internet can be searched by using the basic keyword and the translation keyword, so as to obtain a search webpage related to the basic keyword and the translation keyword. E.g., for the above keyword I1、I2、I3The search condition AND (TERM (I) can be set in the following manner1),TERM(I2),TERM(I3)),FROM(LAN(t1),LAN(t2),LAN(t3) According to the search condition, the search webpage can be obtained after the internet is searched. Where AND denotes the fetching of a web page on the Internet that satisfies one of a plurality of conditions behind AND, TERM (I)1Showing that the web page captured contains the keyword I1,TERM(I2)、TERM(I3) The same is true. FROM sets the language of the search Web page, LAN (t)1) The language representing the web page to be searched is t1,LAN(t2)、LAN(t3) The same is true.
104. And screening out target webpages from all the searched webpages as search results of the basic keywords based on the jumping probability value between every two searched webpages, wherein the jumping probability value is a numerical value calculated according to the jumping relation between the two webpages.

wherein, BprIs a vector of length n, BprThe ith element in (1) isThe correlation value of the ith intermediate search web page, n is the total number of the intermediate search web pages, M is an n x n matrix, each element in M is the jump probability value between every two intermediate search web pages, E is also an n x n matrix, the value of each element in E is 1/n, and alpha is a preset web page jump coefficient;
and screening out intermediate search webpages meeting preset conditions of the correlation values from all the intermediate search webpages to serve as target webpages according to the correlation values of all the intermediate search webpages.
In this alternative embodiment, BprEach element in (a) corresponds to the pagerank score of each intermediate search web page (i.e., the relevance value of the intermediate search web page). α is a preset web page jump coefficient, which can be generally set empirically, and can be generally set to 0.15. E is a random jump matrix for expressing randomness of webpage jumps, so the value of each element in E is set to 1/n.

the method comprises the steps of obtaining a jump probability value of a first webpage jumping to a second webpage in two webpages, c being the number of all jump links in the first webpage, and b being the number of all jump links jumping from the first webpage to the second webpage in the first webpage.
In this alternative embodiment, the jump probability value between the two web pages is a value indicating the possibility of a first web page of the two web pages jumping to a second web page, so that it can be calculated according to the number of all jump links in the first web page and the number of all jump links in the first web page jumping from the first web page to the second web page. For example, there are three jump links in the web page a, and only one jump link is jumped to the web page b, so the jump probability value between the web page a and the web page b is 1/3.

Specifically, the search information of the information is obtained by operating the search method of the information, and is used for recording the search condition of the information, such as the acquired basic keyword, the translated keyword obtained by translation, the searched search webpage, the screened target webpage and the like. Uploading the search information of the information to the block chain can ensure the safety and the fair transparency of the block chain to the user. The user can download the search information of the information from the blockchain so as to verify whether the search information of the search method of the information is tampered. The blockchain referred to in this example is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
