Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for extracting and scoring class-instance pairs. One method includes applying extraction patterns to document text to derive class-instance pairs, determining a frequency score and a diversity score for each distinct class-instance pair, and determining a pair score for each class-instance pair from the frequency score and the diversity score. Another method includes applying extraction patterns to document text to derive candidate class-instance pairs, determining, for each distinct candidate class-instance pair, a number of distinct phrases from which the distinct candidate class-instance pair was derived, and determining a pair score for each distinct candidate class-instance pair from the number of distinct phrases from which the candidate class-instance pair was extracted.
