  • PHRASE BASED DOCUMENT CLUSTERING WITH AUTOMATIC PHRASE EXTRACTION
    Publication number: 20130185060
    Abstract: Meaningful phrases are distinguished from chance word sequences statistically, by analyzing a large number of documents and using a statistical metric such as a mutual information metric to distinguish meaningful phrases from groups of words that co-occur by chance. In some embodiments, multiple lists of candidate phrases are maintained to optimize the storage requirement of the phrase-identification algorithm. After phrase identification, a combination of words and meaningful phrases can be used to construct clusters of documents.
