  • obtaining, by a server, any two words to be identified;

    determining that a shortest edit distance between the two words is less than or equal to an edit distance threshold;

    determining whether both of the two words exist in a preset knowledge database;

    if at least one of the two words does not exist in the preset knowledge database, segmenting one or more unfound words;

    determining whether all of the words after segmentation exist in the knowledge database; and

    if all of the words after segmentation exist in the knowledge database, finding a smallest granularity type with highest weight value for each such word in the knowledge database; and

    if both of the two words exist in the preset knowledge database, then finding the smallest granularity type with highest weight value for each word in the knowledge database;

    determining whether the two words have a same smallest granularity type with highest weight value;

    if the two words have the same smallest granularity type with highest weight value, then determining that the two words are synonyms; and

    if the two words do not have the same smallest granularity type with highest weight value, then determining that the two words are non-synonyms.
