摘要

A document understanding support apparatus as one embodiment of the present invention includes a word extraction condition learning device, a word extractor, a word relationship extraction condition learning device, a word relationship extractor, and an output device. The word extraction condition learning device creates a word extraction condition for extracting words from a target electronic document by machine-learning based on feature values assigned to respective words. The word extractor extracts words satisfying the word extraction condition. The word relationship extraction condition learning device creates a word relationship extraction condition for extracting word relationships from the target electronic document by machine-learning based on feature values with respect to extraction target word relationships. The word relationship extractor extracts a word relationship satisfying the word relationship extraction condition. The output device outputs at least either the extracted words or the extracted word relationship.
