TOEFL Synonym Questions (State of the art)
- TOEFL = Test of English as a Foreign Language
- 80 multiple-choice synonym questions; 4 choices per question
- TOEFL questions available from Thomas Landauer
- introduced in Landauer and Dumais (1997) as a way of evaluating algorithms for measuring similarity
- subsequently used by many other researchers
- Algorithm = name of algorithm
- Reference for algorithm = where to find out more about given algorithm for measuring similarity
- Reference for experiment = where to find out more about evaluation of given algorithm with TOEFL questions
- Algorithm = general type of algorithm: corpus-based, lexicon-based, hybrid
- Correct = percent of 80 questions that given algorithm answered correctly
- 95% confidence = confidence interval calculated using Binomial Exact Test
- table rows sorted in order of increasing percent correct
- several WordNet-based similarity measures are implemented in Ted Pedersen's WordNet::Similarity package
- LSA = Latent Semantic Analysis
- PMI-IR = Pointwise Mutual Information - Information Retrieval
- PR = Product Rule
