14. A method for estimating word correlations, the method comprising: providing a computing device with a conjunctive image representation of a first word and a second word, the conjunctive image representation comprising a first set of multiple images; providing the computing device with a first image representation of the first word and a second image representation of the second word, the first image representation of the first word comprising a second set of multiple images, and the second image representation of the second word comprising a third set of multiple images; and estimating, by the computing device, a correlation between the first word and second word at least partially based on a calculation of visual features calculated from the first set of multiple images comprising the conjunctive image representation of the first word and the second word, the second set of multiple images comprising the first image representation of the first word and the third set of multiple images comprising the second image representation of the second word.
15. The method as recited in claim 14 , wherein estimating, by the computing device, the correlation between the first word and second word comprises calculating, by the computing device, a visual consistence of the first set of multiple images.
