other,12-3-P03-1051,bq The <term> algorithm </term> uses a <term> trigram language model </term> to determine the most probable <term> morpheme sequence </term> for a given <term> input </term> .
model,1-4-P03-1051,bq The <term> language model </term> is initially estimated from a small <term> manually segmented corpus </term> of about 110,000 <term> words </term> .
lr,34-5-P03-1051,bq To improve the <term> segmentation </term><term> accuracy </term> , we use an <term> unsupervised algorithm </term> for automatically acquiring new <term> stems </term> from a 155 million <term> word </term><term> unsegmented corpus </term> , and re-estimate the <term> model parameters </term> with the expanded <term> vocabulary </term> and <term> training corpus </term> .
lr,15-6-P03-1051,bq The resulting <term> Arabic word segmentation system </term> achieves around 97 % <term> exact match accuracy </term> on a <term> test corpus </term> containing 28,449 <term> word tokens </term> .
