Embodiment Construction

[0039] The inventor found through research that, in a recommendation engine application, usually, it is only necessary to record a certain number of recommended content identifiers recently recommended to users. For example, record the most recently recommended 5000 documents. After more than 5,000 articles, the recommendation record of the first recommended historical document can be erased without affecting the user experience. Based on such a concept, the present application provides a data processing method and a data processing device.

[0040] see figure 1 , an embodiment of the present application provides a data processing method, including: steps 101 to 103.

[0041] Step 101: open up an index area and a data area in the storage medium, the index area includes a key (Key) field and a value (Value) field corresponding to each other, and a plurality of data files are included in the data area, each data file Contains multiple data units of the same size.

Abstract

A data processing method, a data processing device, a computing device, and a storage medium. The method comprises: preparing an index area and a data area in a storage medium, wherein the index area comprises key fields and value fields in a one-to-one correspondence with the key fields, the data area comprises a plurality of data files, and each data file comprises a plurality of data units of the same size (101); writing, in one data unit of one data file in the data area, a recommendation record of one user, wherein the recommendation record comprises a pointer and at least one recommended-content identifier, and the pointer is used to store a writing address of a next recommended-content identifier (102); and writing, in the key field, a user ID of the user, and writing, in the value field, the number of the data file in which the recommendation record is located and an offset address of the recommendation record in the data file (103).

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data processing method and a data processing device. Background technique [0002] The recommendation engine is an information network technology that actively discovers the current or potential needs of users and actively recommends information to users. Specifically, the recommendation engine comprehensively utilizes the user's behavior, attributes, object attributes, content, classification, and social relations between users, etc., to mine the user's preferences and needs, and proactively recommend objects of interest or need to the user. . [0003] In the recommendation engine application, it is not expected to recommend the information once recommended to the user to the user again. Every time information is recommended to the user, the recommended information needs to be recorded. When the recommendation list is generated next time, it is necessary to filter out the...
