Assignee: INTUIT INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 13:
14. A classification system comprising:
a data repository storing:
a corpus comprising a plurality of words including a first word;
a machine learning model comprising a plurality of layers and a retrospective layer,
a key phrase comprising a subset of words within the plurality of words,
a first probability that the first word is a first keyword in the key phrase, and
a modified probability that the first word is the first keyword, wherein:
the modified probability is based on a first position of the first word relative to at least one neighbor word in the corpus,
wherein the modified probability punishes the first word when the first word depends on the at least one neighbor word and the at least one neighbor word comes after the first word, and
wherein punishes comprises reducing a probability that the first word is in the key phrase; and

a server comprising a server application, wherein:
the server application is configured to execute the machine learning model to calculate the first probability using the plurality of layers and to calculate the modified probability using the retrospective layer, and
the server application is further application is further configured to predict that the first word is part of the key phrase when the modified probability exceeds a threshold value.
