In some examples, a respective first data representation of each transcript of the plurality of first transcripts may be generated. Unlabeled text data including a plurality of second transcripts may be received. Second data representations of each transcript of the plurality of second transcripts may be generated. A plurality of clusters may be determined. A number of nearest neighbors that are associated with the plurality of first transcripts related to fraudulent activity may be determined for a first instance of the second data representations. A determination may be made that the first instance of the second data representations corresponds to a transcript related to fraudulent activity.
