--- sidebar_position: 3 --- # Clustering functions ## NgramPairs It produces a list of concatenations of a pair of ngrams generated from different words.
*Example:*
Input string: `“Search for the Standard Model Higgs Boson”`
Parameters: ngram length = 3
List of ngrams: `“sea”`, `“sta”`, `“mod”`, `“hig”`
Ngram pairs: `“seasta”`, `“stamod”`, `“modhig”` ## SuffixPrefix It produces ngrams pairs in a particular way: it concatenates the suffix of a string with the prefix of the next in the input string.
*Example:*
Input string: `“Search for the Standard Model Higgs Boson”`
Parameters: suffix and prefix length = 3
Output list: `“ardmod”` (suffix of the word `“Standard”` + prefix of the word `“Model”`), `“rchsta”` (suffix of the word `“Search”` + prefix of the word `“Standard”`)
