stm

stm

Takes in a document, spits out a tokenised and stemmed array of terms. Using Porter's Algorithm.

Usage

stm.stem(text, noStopWords). Returns an array of terms, stemmed and without punctuation.

• text is the string (text document) in which the calculations are to be performed on.
• noStopWords defaults to true. Set to false if you want to include stop words–e.g words such as "I" and "the".

Note: This is basically a wrapper around the stem-porter library by kastor.

var stm = require('stm');

var str = "you're simply a simplistic house, made for housing";
var stemmed = stm.stem(str); // noStopWords -> `true`
>> ["simpli", "simplist", "hous", "hous"]

var withStopWords = stm.stem(str, false); // turn off the removal of stop words
>> [ 'you', 're', 'simpli', 'a', 'simplist', 'hous', 'made', 'for', 'hous'];
