Embodiment Construction

[0042] The present invention will be described in detail below in combination with specific embodiments.

[0043] The technical scheme that the computing method of vocabulary semantic correlation of the present invention adopts is as follows:

[0044] Step 1: Construction of the semantic relationship graph; first, analyze and study the representation of word semantics in HowNet, and extract the Semantic relationship, constructing a semantic relationship graph based on HowNet;

[0045] The semantic relationship graph constructed by the present invention is composed of nodes representing semantics and edges representing relationships between semantic nodes, and the entire semantic relationship graph is stored in the form of triplets in units of edges, that is, each semantic relationship triplet (conclusion Point 1, node 2, semantic relationship) as a storage record. Adopting such a storage method facilitates the expansion of the established semantic relationship graph. When ex...

Abstract

The present invention discloses a method for calculating the word semantic relevancy. According to word semantic information in the how-net and expression characteristics of the how-net for word semantic, semantic relations in the how-net are extracted and a semantic relation graph based on the how-net is constructed; expansion of the semantic relation graph is carried out; and finally, based on the semantic relation graph, calculation of the word semantic relevancy is carried out. The method has the beneficial effects that based on the semantic relation graph, graph theory knowledge is combined with information in the semantic relation graph, the method for calculating the word semantic relevancy on the basis of semantic relation graph is disclosed and the method is verified to be effective and feasible by experiments.

Description

technical field [0001] The invention belongs to the field of language technology, and relates to a calculation method of vocabulary semantic correlation. Background technique [0002] The semantic calculation of vocabulary is one of the important issues in the field of Chinese information processing. The current research mainly focuses on the similarity calculation of vocabulary semantics, and the research on the calculation method of the correlation degree of vocabulary semantics is insufficient. To this end, this paper constructs a semantic relationship graph based on the semantic relationship between concepts and the attributes of concepts in HowNet and the word dependency relationship calculated from large-scale corpus. Then, combining the semantic relationship graph with the relevant knowledge of graph theory, a method for calculating the semantic relevancy of words based on the semantic relationship graph is proposed. Experimental results show that this method is effe...
