Knowledge graph construction and application for improving search recalls

A system comprising:

• a communications interface;
• a non-transitory computer-readable medium;
• and
• one or more processors communicatively coupled to the communications interface and the non-transitory computer-readable medium, the one or more processors configured to execute processor-executable instructions stored in the non-transitory computer-readable medium to:
• access communication data on a communication platform associated with an enterprise;
• extract a plurality of keywords from the communication data;
• create a knowledge graph comprising a plurality of nodes, the plurality of nodes comprising a plurality of keyword nodes;
• identify, using a graph random walk algorithm, one or more keyword nodes in the knowledge graph related to a first keyword node;
• link the first keyword node and the one or more keyword nodes;
• determine a first keyword node embedding for the first keyword node based at least on information associated with the first keyword node and the one or more keyword nodes using a graph convolutional network algorithm;
• and
• attach the first keyword node embedding to the first keyword node in the knowledge graph.
