Query: Zipf's law holds for phrases, not words   With Zipf's law being originally and most famously observed for word
frequency, it is surprisingly limited in its applicability to human language,
holding over no more than three to four orders of magnitude before hitting a
clear break in scaling. Here, building on the simple observation that phrases
of one or more words comprise the most coherent units of meaning in language,
we show empirically that Zipf's law for phrases extends over as many as nine
orders of rank magnitude. In doing so, we develop a principled and scalable
statistical mechanical method of random text partitioning, which opens up a
rich frontier of rigorous text analysis via a rank ordering of mixed length
phrases.
