Abstract
In this paper, we experimentally evaluate the effect of the Part-of-Speech (POS) tagging on Information Retrieval performance for Turkish. We used four term-weighting schemas to index SABANCI-METU Turkish Treebank corpus. The term weighting schemas are ” tf”, ”tf x idf”, ”Ltu.ltu”, and ”Okapi”. Each weighting scheme is factored over three POS tagging cases that are namely ”No POS tagging”, ”POS tag with no history (i.e. 1-gram)”, and ”POS tag with one step his tory (i.e. 2-gram)”. The Meta-scoring function is used to analyze the effect of these nine factors on IR performance. Results show that weighting schema are significantly different from each other with a p-value of 0.04 (Friedman Non-parametric Test), but there is not enough evidence in the corpus to reject the null hypothesis that the three weighting schemas, on the average, show equal performance over the three cases of POS tagging with a p-value of 0.36.
