1. A method for detecting deviations in obligations, comprising:
based on a pairwise sentence alignment between a standard sentence in a standard document and a review sentence in a review document, converting the standard sentence and review sentence into respective feature sets for a classifier model;
generating a predicted similarity between the standard sentence and review sentence associated with the pairwise sentence alignment by applying the classifier model to the respective feature sets for the standard sentence and review sentence;
in response to the predicted similarity between the standard sentence and the review sentence being above a defined similarity threshold, identifying any differences between actors, obligations and restrictions of the standard sentence and review sentence; and
in response to identifying the differences between the actors, obligations and restrictions of the standard sentence and review sentence, causing display of visual data associated with the differences via a user interface of a user computing device.
