Abstract
According to an embodiment, a contextual analysis device includes a generator, an predictor, and a processor. The generator is configured to generate, from a target document for analysis, an predicted sequence in which some elements of a sequence having elements arranged therein are obtained by prediction. Each element is a combination of a predicate having a common argument, word sense identification information of the predicate, and case classification information indicating a type of the common argument. The predictor is configured to predict an occurrence probability of the predicted sequence based on a probability of appearance of the sequence that is acquired in advance from an arbitrary group of documents and that is matching with the predicted sequence. The processor is configured to perform contextual analysis with respect to the target document by using the predicted occurrence probability of the predictepredictord sequence.
