Viewing stemming as recall enhancement
Wessel Kraaij, Renée Pohlmann · 1996
Previous research on stemming has shown both positive and negative effects on retrieval performance.This paper describes an experiment in which several linguistic and non-linguistic stemmers are evaluated on a Dutch test collection.Experiments especially focus on the measurement of Recall.Results show that linguistic stemming restricted to inflection yields a significant improvement over full linguistic and non-linguistic stemming, both in average Precision and R-Recall.Best results are obtained with a linguistic stemmer which is enhanced with compound analysis.This version has a significantly better Recall than a system without stemming, without a significant deterioration of Precision.
