SAT Analogy Questions (State of the art)
- 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 |
|---|---|---|---|---|
| KNOW-BEST | Veale (2004) | lexicon-based | 43.0% | 38.0-48.2% |
| VSM | Turney and Littman (2005) | corpus-based | 47.1% | 42.2-52.5% |
| PERT | Turney (2006a) | corpus-based | 53.5% | 48.5-58.9% |
| LRA | Turney (2006b) | corpus-based | 56.1% | 51.0–61.2% |
