Towards this goal , we also propose a novel Multiple Instance Learning -LRB- MIL -RRB- formulation for the problem based on the logistic softmax function of covariance-based region features within a MAP estimation framework .
 used for: logistic softmax function of covariance-based region features, Multiple Instance Learning -LRB- MIL -RRB- formulation; used for: MAP estimation framework, Multiple Instance Learning -LRB- MIL -RRB- formulation
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".
