Abstract

The invention relates to the technical field of big data, and discloses a user portrait-based information recommendation method. The method comprises the following steps: receiving a man-machine conversation chat record in a first scene in real time through a log collection system Flume; performing desensitization processing on the chat record to obtain first data; performing stop word removal processing on the first data to obtain second data; extracting a keyword of the second data through a preset word graph; obtaining a first label set according to the keyword; performing duplicate removalon the first label set data to obtain a second label set; generating a user interest portrait based on the second label set, and storing the user interest portrait in a database; receiving a recommendation instruction, and obtaining a user interest portrait according to the recommendation instruction; and obtaining to-be-recommended information corresponding to the recommendation instruction according to the user interest portrait. The invention also provides an information recommendation device and equipment based on the user portrait, and a storage medium. The information recommendation method based on the user portrait provided by the invention improves the accuracy of the user portrait.

Description

technical field [0001] The present invention relates to the field of big data technology, in particular to an information recommendation method, device, equipment and storage medium based on user portraits. Background technique [0002] At present, for customer service and functional robots, user interaction is very purposeful. Even if the current robots cannot meet the needs of users, they still contain certain interests and concerns brought by users. The current industry cannot effectively extract user interest tags based on conversation content, and enable user interest tags to be applied in actual application scenarios of application software, such as product and advertisement recommendation scenarios. Because in the prior art, the way of generating user portraits based on user interest tags, when applied to information recommendation scenarios, there will be inaccurate recommendations. The root cause is that the accuracy of existing user portraits is relatively low. C...
