Quantitative Approaches to Universality and Individuality in Language [PDF ebook] 

Quantitative linguistic research reveals fascinating patterns in contemporary and historical linguistic data. The book offers insights from a broad range of languages, including Japanese, Slovene and Catalan. The reader is convinced that statistic empirical analysis — and increasingly also machine learning and big data — should be an essential part of any serious linguistic enquiry.
