Paper Abstract:
|
This paper presents a new management method for morphological variation of query 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 five languages, English, Finnish, German, Russian and Swedish, which
show varying degrees of morphological complexity. The paper reports automatic procedure of variant query keyword
form generation that simulates usage by a real user of a search engine. We report results of automatized query generation
process of short title queries of CLEF collections for English, Finnish, German and Swedish. |
