Detailed Description

define the feature style. such as "w3"(word-3gram); "c2"(class-2gram);

Author: wangbin

Date

2015-12-10 using "w" denotes the word, "c" denote the class, "-" denote the skip, and "0-9" in "[]" denote the order different orders correspond to different template support the skip-gram, such as :

"w[3]" (word-3gram); "c[2]" (class-2gram); "w[1:5]" (word ngram with order 1 to 5)
"w[2]-[2]w[1]" (skip-word-3gram, ww–w);
"w[2]-[1]c[2]" (skip-word-class-gram, ww–cc);
"w[2]-[1:2]w[1]" (tried-skip-word-gram, ww [1:2] w);
