example 1

[0056] Example 1: Based on aliases in encyclopedia entries. For example, if an entry is: A, also known as B, then A and B are synonyms for each other.

example 2

[0057] Example 2: Based on a dictionary of synonyms. For example, words that are synonyms of each other are recorded in the thesaurus dictionary, so synonyms can be determined based on the thesaurus dictionary.

example 3

[0058] Example 3: Manual labeling. For example, synonyms of words are manually annotated by domain experts.
