Abstract
Systems, methods, and non-transitory computer-readable media can obtain at least one content item for which a hash value is to be generated. A set of n-grams can be generated based at least in part on the at least one content item. A first vector can be generated based at least in part on the set of n-grams, wherein the vector maintains respective counts of n-grams in the set of n-grams. A quantized vector can be determined based at least in part on the first vector and one or more parameters. The hash value for the at least one content item can be generated based at least in part on the quantized vector.
