Another task used for evaluation is the analogy task, discussed on page 120, where the system has to solve problems of the form a is to b as a* is to b*, given a, b, and a* and having to find b* (Turney and Littman, 2005) . A number of sets of tuples have been created for this task, (Mikolov et al. 2013a , Mikolov et al. 2013c , Gladkova et al. 2016 , covering morphology (city:cities::child:children), lexicographic relations (leg:table::spout::teapot) and encyclopedia relations (Beijing:China::Dublin:Ireland), some drawing from the SemEval-2012 Task 2 dataset of 79 different relations (Jurgens et al., 2012) .
