  • SAT= Scholastic Aptitude Test
  • 374 multiple-choice analogy questions; 5 choices per question
  • SAT questions collected by Michael Littman, available from Peter Turney
  • introduced in Turney et al. (2003) as a way of evaluating algorithms for measuring relational similarity
  • Algorithm = name of algorithm
  • Reference = source for algorithm description and experimental results
  • Type = general type of algorithm: corpus-based, lexicon-based, hybrid
  • Correct = percent of 374 questions that given algorithm answered correctly
  • 95% confidence = confidence interval calculated using Binomial Exact Test
  • table rows sorted in order of increasing percent correct
  • VSM = Vector Space Model
  • LRA = Latent Relational Analysis


Algorithm Reference Type Correct 95% confidence
VSM Turney and Littman (2005) corpus-based 47.1% 42.2-52.5%
LRA Turney (2006) corpus-based 56.1% 51.0–61.2%
