Treebank synthesis for training production parsers

A computer program product for generating synthetic treebanks to be used in training of a parser in a production system, the computer program product comprising:

• one or more computer-readable storage media and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
• program instructions to receive a request to generate one or more synthetic treebanks from a production system, wherein the request indicates a language for the one or more synthetic treebanks;
• program instructions to retrieve at least one corpus of text in which the requested language is present;
• program instructions to provide the at least one corpus to a transformer enhanced parser neural network model;
• program instructions to generate at least one synthetic treebank associated with a string of text from the at least one corpus of text in which the requested language is present, wherein the at least one synthetic treebank is generated with unsupervised training of the transformer enhanced parser neural network model;
• and
• program instructions to send the at least one synthetic treebank to the production system, wherein the production system trains a parser utilized by the production system with the at least one synthetic treebank.

A computer system for generating synthetic treebanks to be used in training of a parser in a production system, the computer system comprising:
