Abstract
A computer-implemented method includes performing a frequency analysis on unlabeled access data to identify high frequency occurrences and low frequency occurrences in the unlabeled access data; grouping the occurrences into groupings based on the frequency analysis; generating access-data corpora based on the groupings, and an initial dictionary using a similarity algorithm, wherein the initial dictionary is manually created from the unlabeled access data, and wherein the access-data corpora comprise n-gram dictionaries; determining, by an unsupervised natural language processing module, first multi-label classifications for the unlabeled access data, wherein the first multi-label classifications are based on the access-data corpora; determining, by a supervised neural network, second multi-label classifications for the unlabeled access data, wherein the second multi-label classifications are based on the access-data corpora and a manually-labeled subset of the access data; and applying multi-label classifiers to the unlabeled access data based on the first and second multi-label classifications.
