Japanese Word Similarity API

2015/11/03

By using Japanese Word Similarity API, you can create an application which calculates and returns a similarity score between two Japanese words.

Overview: Japanese Word Similarity API

Japanese Word Similarity API calculates a similarity score between the sent-in two Japanese words. The scoring criteria of this API is based on pronunciation of each word.

For example, the high similarity score is calculated to a set of words which have similar readings such as "Toukyou" and "Tokyo". The range of similarity score is from 0 to 1. And when the score is more than 0.3, the pair is similar enough.

This similarity score is useful when disambiguating records from several data sources, whose manner of writing is different between each other.
