Abstract
According to an aspect, passage justification scoring is implemented by a processor executing computer readable instructions. The computer readable instructions include creating a multi-layered neural network from domain knowledge and training the multi-layered neural network with labeled data and unlabeled data. The computer readable instructions further include inputting at least one of an existing passage justification component and raw input data for a question and passage to the multi-layered neural network, extracting concepts determined to have passage justification with respect to a candidate answer contained in a respective passage, and creating a passage justification model from the extracted concepts and from passage justification ground truth.
