igrepl

This function takes character vector <code>patterns</code> with regex patterns
(or fixed strings),
and searches for match in the <code>x</code> string. It is inverse in the meaning,
that in <a href="/link/grepl?package=NUSS&version=0.1.0" data-mini-rdoc="NUSS::grepl">grepl</a> single pattern is used against multiple strings;
instead, this function takes multiple patterns to fit on a single string.

Segmentation of short text sequences - like hashtags - into the
separated words sequence, done with the use of dictionary, which may be
built on custom corpus of texts. Unigram dictionary is used to find most
probable sequence, and n-grams approach is used to determine possible
segmentation given the text corpus.
