There is a need for more effective and efficient text categorization. This need can be
addressed by, for example, techniques for semantic text categorization. In one example, a
method includes determining an input vector-based representation of an input document;
processing the input vector-based representation using a trained supervised machine
learning model to generate the categorization based at least in part on the input vector-
based representation, wherein:(i) the trained supervised machine learning model has been …
