sphinx.util.stemmer.StandardStemmer

Method stem No summary

Inherited from PorterStemmer:

Method	`__init__`	No summary
Method	`cons`	cons(i) is TRUE <=> b[i] is a consonant.
Method	`cvc`	No summary
Method	`doublec`	doublec(j) is TRUE <=> j,(j-1) contain a double consonant.
Method	`ends`	ends(s) is TRUE <=> k0,...k ends with the string s.
Method	`m`	m() measures the number of consonant sequences between k0 and j. if c is a consonant sequence and v a vowel sequence, and <..> indicates arbitrary presence,
Method	`r`	r(s) is used further down.
Method	`setto`	setto(s) sets (j+1),...k to the characters in the string s, readjusting k.
Method	`step1ab`	step1ab() gets rid of plurals and -ed or -ing. e.g.
Method	`step1c`	step1c() turns terminal y to i when there is another vowel in the stem.
Method	`step2`	step2() maps double suffices to single ones. so -ization ( = -ize plus -ation) maps to -ize etc. note that the string before the suffix must give m() > 0.
Method	`step3`	step3() dels with -ic-, -full, -ness etc. similar strategy to step2.
Method	`step4`	step4() takes off -ant, -ence etc., in context <c>vcvc<v>.
Method	`step5`	step5() removes a final -e if m() > 1, and changes -ll to -l if m() > 1.
Method	`vowelinstem`	vowelinstem() is TRUE <=> k0,...j contains a vowel

def stem(self, word):

overrides sphinx.util.stemmer.porter.PorterStemmer.stem

In stem(p,i,j), p is a char pointer, and the string to be stemmed is from p[i] to p[j] inclusive. Typically i is zero and j is the offset to the last character of a string, (p[j+1] == ''). The stemmer adjusts the characters p[i] ... p[j] and returns the new end-point of the string, k. Stemming never increases word length, so i <= k <= j. To turn the stemmer into a module, declare 'stem' as extern, and delete the remainder of this file.
