Embodiment 1

[0019] According to an embodiment of the present invention, a method embodiment that can be executed by the device embodiment of the present application is provided. It should be noted that the steps shown in the flowchart of the accompanying drawing can be executed in a computer system such as a set of computer-executable instructions. and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

[0020] According to an embodiment of the present invention, an information retrieval method is provided.

[0021] Optionally, in this embodiment, the above-mentioned information retrieval method can be applied to figure 1 In the hardware environment constituted by the terminal 101 and the server 102 shown. like figure 1 As shown, the terminal 101 is connected to the server 102 through the network, and sends the keyword to be retrieved and the information of the terminal 101 to the serv...

Embodiment 2

[0077] According to an embodiment of the present invention, an information retrieval device for implementing the above information retrieval method is also provided. The information retrieval device is mainly used for executing the information retrieval method provided by the above content of the embodiment of the present invention. The provided information retrieval device is introduced in detail:

[0078] Optionally, in this embodiment, the above-mentioned information retrieval apparatus may be applied to figure 1 In the hardware environment constituted by the terminal 101 and the server 102 shown. like figure 1 As shown, the terminal 101 is connected to the server 102 through the network, and sends the keyword to be retrieved and the information of the terminal 101 to the server 102. After the server 102 receives the keyword to be retrieved, it performs the retrieval key according to the information submitted by the terminal 101. Word matching, after finding the content m...

Embodiment 3

[0108] According to an embodiment of the present invention, there is also provided a server for implementing the above information retrieval method, such as Image 6 As shown, the server includes: a processor 501 , a user interface 502 , a memory 503 and a network interface 504 .

[0109] The memory 503 is mainly used for storing the program code of the above-mentioned information retrieval method, and can also store the first social network information and the second social network information. The memory 503 may be a memory integrated in the server 102 or a memory externally connected through a data transmission line, and the memory 503 is not limited in this embodiment.

[0110] The user interface 502 is used to connect the terminal 101, and transmit the requesting user identifier and the keyword to be searched which are indicated to the server 102 by the client in the terminal 101.

[0111]The processor 501 is mainly configured to perform the following operations: acquiri...

Abstract

The invention discloses an information retrieval method and device. The method comprises following steps: obtaining a first request user identifier carried in a first retrieval request, a first association user identifier associated with the first request user identifier, the identifier of the first social contact network information issued by a first association user, a second request user identifier carried in a second retrieval request, a second association user identifier associated with the second request user identifier, and the identifier of the second social contact network information issued by a second association user; generating a first set according to the first request user identifier and the first association user identifier; searching social contact network information matching with the retrieval key words carried in the first retrieval request from the first social contact network information and the second social contact network information, taking the searched social contact network information as the third social contact network information; and selecting a member from the first set as a retrieval result. Through the invention, the technical problem in the prior art that the retrieval efficiency in retrieval is low is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular, to an information retrieval method and device. Background technique [0002] With the popularization of social platforms, more and more retrieval needs to be performed in the social network information (such as signatures, microblogs, published articles, etc.) owned by associated friends and fans. When performing retrieval in the prior art, it is necessary to send the relationship chain between each friend associated with the initiating searcher and all documents belonging to the friend to the retrieval platform, and the retrieval platform takes the intersection of the keywords to be retrieved and the documents of each friend. , and then perform a union operation on the intersection results of multiple friends, so as to obtain all social network information including the keywords to be retrieved. [0003] However, when there are many friends who initiate a search, resulting ...
