|
## NgramPairs
|
||
|
|
It produces a list of concatenations of a pair of ngrams generated from different words.<br />
|
||
|
|
*Example:*<br />
|
||
|
|
Input string: `“Search for the Standard Model Higgs Boson”`<br />
|
||
|
|
Parameters: ngram length = 3<br />
|
||
|
|
List of ngrams: `“sea”`, `“sta”`, `“mod”`, `“hig”`<br />
|
||
|
|
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.<br />
|
||
|
|
*Example:*<br />
|
||
|
|
Input string: `“Search for the Standard Model Higgs Boson”`<br />
|
||
|
|
Parameters: suffix and prefix length = 3<br />
|
||
|
|
Output list: `“ardmod”` (suffix of the word `“Standard”` + prefix of the word `“Model”`), `“rchsta”` (suffix of the word `“Search”` + prefix of the word `“Standard”`)
