摘要: This paper addresses the problem of identifying collection dependent stop-words in order to reduce size inverted files. We present four methods automatically recognise stop-words, analyse tradeoff between efficiency and effectiveness, compare them with a previous pruning approach. The experiments allow us conclude that some situations is competitive respect other file reduction techniques.
