Problems solved by technology

Intelligent customer service robots can answer simple text questions from users, but are not good at handling complex and vague questions
Since users will send complex or vague questions, intelligent customer service robots cannot recommend accurate information to users, which increases the difficulty of intelligent customer service robots and reduces user experience

Abstract

The embodiment of the invention discloses a method, system and device for determining an atlas for information recommendation. The method comprises the following steps: acquiring a plurality of nodesfor constructing a target graph; the nodes at least comprising word nodes and knowledge point nodes; if the node is a word node, taking the vector representation of the word corresponding to the nodeas the vector representation of the node; if the node is a knowledge point node, determining vector representation corresponding to the knowledge point node based on vector representation of words related to the knowledge point node; for any two nodes, determining an edge weight between the two nodes based on the types of the two nodes, and taking the edge weight as an association relationship between the two nodes; and performing at least one round of graph aggregation iteration based on the vector representation of the nodes and the association relationship between the nodes so as to updatethe vector representation of the nodes in the graph.

Description

technical field [0001] This description relates to the field of data processing, and in particular to a method, system and device for determining a graph for information recommendation. Background technique [0002] With the development of science and technology, the emergence of artificial intelligence provides new solutions for industries that used to require a lot of labor costs, such as manual customer service. Intelligent customer service robots can answer simple text questions from users, but they are not good at handling complex and vague questions. Since users will send complex or vague questions, intelligent customer service robots cannot recommend accurate information to users, which increases the difficulty of intelligent customer service robots and reduces user experience. Contents of the invention [0003] One of the embodiments of this specification provides a method for determining a map used for information recommendation. The method includes: obtaining a...
