The Word Match is an Extractor Type found in Grooper. This extractor is designed to collect full words and is often used in n-gram extraction.
About
The Word Match extractor is designed for n-gram extraction. An n-gram is "a contiguous sequence of n items from a given sample of text or speech." [1] Typically in Grooper, this refers to extracting words or phrases from a lexicon of terms.
Grooper generally uses n-grams for the purpose of feature collection for Lexical Classification. The Word Match extractor can capture 1-grams (single words) up to 5-grams (five word phrases). Lexicons are commonly used to dictate a dictionary of allowable returned words. This could be general Lexicon of common English words or a custom Lexicon, such as one with industry specific terms.
| FYI |
An n-gram is often referred to by a different name depending its n size.
As an additional FYI, four-grams are not called "tetragrams" because the term already has usage as a single word consisting of four letters or characters. "Quadrigram" is occasionally used, but four-gram is the more common terminology. Five-grams are not called "pentagrams", because that already has common usage for a geometric figure. |
