Systems and methods for tagging datasets using models arranged in a series of nodes

A system for tagging datasets comprising:

• at least one processor;
• and
• at least one non-transitory memory storing instructions that, when executed by the at least one processor cause the at least one processor to perform operations comprising:
• receiving a dataset;
• inputting the dataset into a first machine-learning model;
• receiving a first output from the first machine-learning model in response to the input dataset, the first output including a first probability of a first category associated with the dataset and a first tag associated with the first category;
• selecting, among a plurality of second machine-learning models, a particular second machine-learning model based on the first probability;
• inputting the dataset into the selected second machine-learning model;
• receiving a second output from the selected second machine-learning model based on the dataset, the second output including a second probability of a sub-category of the first category and a second tag associated with the sub-category;
• generating a data structure including the first tag and the second tag;
• and
• causing a display to present the generated data structure.
