【分享】Wikipedia Keyphraseness

This dataset contains a collection of keyphraseness values for phrases extracted from Wikipedia articles. The keyphraseness value Q(s) of a phrase s is the probability that the phrase appears in a Wikipedia article as being anchor text. In total,  4,342,732 phrases are extracted from the English Wikipedia dump created on January 30, 2010. In this release, we remove the 184,979 phrases containing non-English characters. Among the remaining 4,157,753 phrases, about 1.9 million phrases have non-zero keyphraseness values. This dataset contains one text file and a readme file in zip format (about 45MB in size). Each line is a mapping: [phrase],[keyphraseness value] (e.g., jackie_chan, 0.9509918319719953).
