Explanation of Calculating Word Similarity Using a Thesaurus
This method calculates the similarity between words using a thesaurus as a reference. It takes into account the hierarchical depth of each word within the thesaurus and the depth of their common ancestor node.
Calculation Mechanism
Depth: Depth is determined based on the hierarchy in the thesaurus, with the top level (Root) defined as 0.
Similarity (Sim): Similarity is calculated as a value between 0 and 1, where a value closer to 1 indicates higher similarity.
The formula for calculation uses the depth of the two words (dwd_wdw) and the depth of their common ancestor node (dcd_cdc).
Example: Similarity Between “Fox” and “Miso”
The thesaurus is used to calculate the depths of “Fox” and “Miso,” as well as the depth of their common ancestor node, “Noodles.”
The resulting similarity is 0.333, which is within the range of 0 to 1.
