Subject RE: Use case for the Shingle Filter
Date Sun, 05 Mar 2017 10:47:55 GMT
Hello - we use it for text classification and online near-duplicate document detection/filtering.
Using shingles means you want to consider order in the text. It is analogous to using bigrams
and trigrams when doing language detection, you cannot distinguish between Danish and Norwegian
solely on single characters.
