Claim 10:
11. A non-transitory computer-readable medium having instructions stored thereon that are executable by a computing device to perform operations, comprising:
generating one or more labelling functions for at least one text data category, wherein the one or more labelling functions are generated based on contextual patterns for the at least one text data category, and wherein the contextual patterns are extracted from a lexical database of semantic relations between words;
accessing a dataset that includes a plurality of unlabeled text data in a freeform format;
determining a set of probabilistic labels for the at least one text data category by applying the generated labelling functions to the unlabeled text data using an unsupervised machine learning algorithm without any truths; and
generating one or more classifiers for a transformer-based machine learning algorithm by applying the set of probabilistic labels to the unlabeled text data in the transformer-based machine learning algorithm, wherein the one or more classifiers are generated to classify text data into the at least one text data category.
