Built a NLP framework using Allennlp, pytorch in python. It can be used for wide variety of NLP related tasks ie. multilabel multiclass classification (labelling the defects in manufacturing batch after reading the review from the QA engineer), reading comprehension (understanding the contracts and then answering the user's questions). This framework is implemented using Flask API with mail notifications. The parameters of the models can be manually iterated by the user.
