Abstract

The invention discloses a method and device for pushing information in real time. The method comprises the steps: receiving current behavior data of a user in real time through a message publishing and subscribing system, and storing the current behavior data in a database; acquiring n pieces of historical behavior data closest to the moment before the current behavior data occurs from a database,determining N Items corresponding to the N pieces of historical behavior data, and setting the N to be a positive integer; respectively calculating the similarity between each Item in the N Items andthe Item corresponding to the current behavior data according to an Item reverse lookup table, and updating a similarity matrix stored in a database according to the similarity. The whole process iscalculated according to the real-time historical behavior data, the effectiveness is high, the pushing result conforms to the will of the user, the user experience is good, and problems that in the prior art, when recommendation is conducted based on an offline model, real-time personalized recommendation cannot be truly achieved, and the system performance is poor are solved.

Description

[0001] This application is a divisional application of a patent application with an application date of December 26, 2016, an application number of 201611217545.3, and an invention title of "A Method and Device for Pushing Information in Real Time". technical field [0002] The invention relates to the communication field, in particular to a method and device for pushing information in real time. Background technique [0003] In the existing technology, many systems have realized the personalized recommendation function, but due to the relatively large amount of data, the recommendation results are calculated offline, and the recommendation model needs to be updated regularly, and the fastest of many systems can only achieve hour-level Moreover, a large part of the recommendations are based on search. However, these recommendation results do not take into account the real-time behavior of users, and lose the timeliness of user interests, so that the recommendation results are...
