The classifier we use in both stages is based on a boosted combination of Random Ferns over local histograms of oriented gradients -LRB- HOGs -RRB- , which we compute during a pre-processing step .
 used for: boosted combination of Random Ferns, classifier; feature of: local histograms of oriented gradients -LRB- HOGs -RRB-, boosted combination of Random Ferns; used for: pre-processing step, local histograms of oriented gradients -LRB- HOGs -RRB-
Given a phrase that describes the relationship between two words, extract the words and the lexical relationship between them. The output format should be "relation1: word1, word2; relation2: word3, word4".
