Before revision:  (2)  Schema2QA translates natural language into executable queries on the up-to-date data from the website; (3) natural language training can be applied to one domain at a time to handle multiple websites using the same URL representations .
After revision:  (2) Schema2QA uses a novel neural model that combines the BERT pretrained model with an LSTM; the model can generalize a training set containing only synthesized and paraphrase data to understand real-world crowdsourced questions .
