1. One or more computer-readable storage media device storing computer-readable instructions that, when executed, instruct one or more processors to perform operations comprising: providing recommended groupings of clustered data based at least in part on clustering data of a first data set; receiving an indication from a user that a first portion of the first data set is associated with a bucket, the indication based at least in part on an evaluation by the user of at least one of the recommended groupings; generating a classification model based at least in part on the indication, one or more data signatures based at least in part on one or more of units of data, input patterns of data, order and proximity of terms, or combinations thereof, and one or more bucket patterns based at least in part on one or more cluster patterns, cluster signatures, input data patterns, or a combination thereof; generating classified data based at least in part on applying the classification model to a second data set based at least in part on comparing a data signature of the one or more data signatures to a bucket pattern of the one or more bucket patterns; identifying a subset of data of the first data set, of the second data set, or a combination thereof; providing another recommended groupings of clustered data based at least in part on clustering data of the subset of data; receiving another indication from a user that a first portion of the subset of data is associated with another bucket, the another indication based at least in part on an another evaluation by the user of at least one of the another recommended groupings; generating another classification model based at least in part on the another indication; and generating another classified data based at least in part on applying the another classification model to a third data set.
