Abstract

This paper presents a new management method for morphological variation of keywords. The method is called FCG, Frequent Case Generation. It is based on the skewed distributions of word forms in natural languages and is suitable for languages that have either fair amount of morphological variation or are morphologically very rich. The proposed method has been evaluated so far with four languages, Finnish, Swedish, German and Russian, which show varying degrees of morphological complexity.
