Description
------------

This corpus contains 30 Wikipedia article pairs in English and Spanish. 
The articles correspond to three domains in equal proportions: Computer Science, 
Science, and Sports.

Two volunteers, native speakers of Spanish with high command of English, annotated 
it manually at sentence level considering three classes: parallel, comparable, 
and other. The mean agreement between annotators had a kappa coefficient of 
κ∼0.7. A third annotator resolved disagreed sentences.
