The invention relates to the field of
artificial intelligence, and provides a
word sense disambiguation method and device based on a graph expansion structure, equipment and a medium, which can extract candidate nodes in an initial graph according to a created window, realize the expansion of the graph, and then improve the
connectivity. The weight of each edge is calculated according to the text similarity between the two candidate nodes corresponding to each edge and the
word meaning similarity between the two candidate nodes corresponding to each edge, and the importance of each candidate node is determined according to the weight of each edge, so that high semantic and emotion information is explored and captured, and the
word meaning disambiguation accuracy is improved; and according to the importance degree of each candidate node, interference removal
processing is performed on the candidate map to obtain a target map, so that the
word sense disambiguation efficiency is improved through interference removal
processing, center measurement is carried out on the target map to obtain a target
word sense, and the improvement of the
word sense disambiguation effect is realized. In addition, the invention also relates to a block chain technology, and the target map can be stored in a block chain node.
