How Random is a Corpus? The Library Metaphor

  • Stefan Evert


There is a stark contrast between the random sample model underlying the statistical analysis of corpus frequency data and our intuitive knowledge that sentences are more than random bags of words. The 'library metaphor' illustrates how randomness results from the selection of a corpus as the basis for a linguistic study. At the same time it reveals two reasons why corpus data do not fully meet the assumptions of the random sample model. Finally, practicable methods for identifying and quantifying non-randomness are introduced and demonstrated on the example of passive verb forms.
