High Quality Content by WIKIPEDIA articles! Semantic relatedness is a measure of how related two or more concepts are. Semantic relatedness is used for essay-grading by the Educational Testing Service, search engine technology, predicting which links people are likely to click on, etc. Measures of relatedness include: LSA (Latent semantic analysis) (+) vector-based, adds vectors to measure multi-word terms; (-) non-incremental vocabulary, long pre-processing times. PMI (Pointwise Mutual Information) (+) large vocab, because it uses any search engine (like Google); (-) cannot measure relatedness between whole sentences or documents. SOC-PMI (Second Order Co-occurrence PMI) (+) sort lists of important neighbor words from a large corpus; (-) cannot measure relatedness between whole sentences or documents
