Claim 15:
16. The classification system of claim 14, further comprising:
a training application configured to train the machine learning model,
wherein the corpus further comprises a plurality of known key phrases comprising a plurality of known keywords, and
wherein the training application is further configured to train the machine learning model prior to use of the machine learning model by:
inputting at least part of the corpus as a vector into the machine learning model,
determining, using the plurality of layers, the first probability that the first word in the corpus is the first keyword in at least one of a plurality of predicted key phrases,
determining, using the retrospective layer, a modified probability that the first word is the first keyword based on the first position of the first word relative to a second position of the at least one neighbor word in the corpus,
predicting, using the machine learning model, the plurality of predicted key phrases, wherein at least one of the plurality of predicted key phrases comprises at least the first word,
calculating a loss function by comparing and evaluating a difference between the plurality of predicted key phrases and the plurality of known key phrases, and
modifying the machine learning model using the loss function.
