Problems solved by technology
[0004] However, in the current method of pushing information to users based on clustering results, if clustering based on word vectors or feature vectors is used, there is a problem of missing semantics, and the recall rate of clustering results is low; Class method, since the high-level semantic features are usually high-dimensional arrays or floating-point arrays, the efficiency of similarity calculation is low
Therefore, the current method of pushing information to users has the problem of lack of semantics or low computational efficiency

The invention discloses an information pushing method and device. One embodiment of the information pushing method includes: acquiring historical pushing information; inputting the historical pushing information in a deep learning model, and acquiring implicit layer output data of the deep learning model; encoding the implicit layer output data to acquire encoded data; clustering historical pushing information with the same encoded data to acquire a historical pushing information cluster; and responding to the situation that the number of the historical pushing information in the historical pushing information cluster is less than a preset threshold, and pushing information to a user based on the historical pushing information cluster. The information pushing method balances the clustering efficiency and the accuracy of the clustering result, and then improves the efficiency and the pertinence of information pushing.
Description
technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method and device for pushing information. Background technique [0002] At present, the background server of the search page usually clusters similar questions among historical questions, and then extracts the latest and highest-quality questions and answers based on the clustering results, and displays them preferentially when users search for answers to questions. That is to push the latest and highest quality questions and answers to users. [0003] When clustering similar problems in historical problems, the text of the problem can be converted into word vectors or feature vectors, and then cluster the texts according to the similarity of word vectors or feature vectors; or use natural language processing technology or machine learning technology Get the high-level semantic features of the text, and then cl...
