Abstract

The embodiment of the invention discloses a data updating method and device, electronic equipment and a computer readable medium. A specific embodiment of the method comprises the following steps: processing an obtained user behavior log to obtain target data; according to the target data, changing a time record file and data in related behavior record files in a behavior record file set, wherein the time record file stores data of each user whose behavior occurs in a preset time period, and the behavior record files in the behavior record file set store behavior data of different users; in response to determining that the current time reaches the updating time, determining whether data change exists in a preset time period or not according to the time recording file; and in response to determining existence, updating the reverse index file according to the time record file and the behavior record file set. According to the embodiment, incremental updating of the reverse index file can be realized. Not only can the data updating efficiency be improved, but also the real-time performance of the data can be ensured.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular, to a data updating method, device, electronic equipment, and computer-readable medium. Background technique [0002] Collaborative filtering, in simple terms, generally uses the preferences of a group with similar interests and common experiences to recommend information that users are interested in. Individuals give information a certain degree of response (such as scoring) through a cooperative mechanism and record it to achieve the purpose of filtering and help others to filter information. Responses are not necessarily limited to those of particular interest; records of information of particular disinterest are also important. [0003] This recommendation method usually has the following problems: [0004] First, the real-time performance is poor, and the data update efficiency is low. Because the data is always changing, and the changed data...
