The resulting key phrases are used for clustering and classi cation of recorded phone conversations in speech-recognition related products. The main problem was design and implementation of an algorithm, that can select meaningful ngrams from texts for ranking. The text were error-prone due to mistakes of the automatic recognition engine and the bad grammar of humans' spoken language.
