 Some of the components, with provided pre-trained models, are exposed as REST service APIs through NLP Architect server. NLP Architect server is designed to provide predictions across different models in NLP Architect. It also includes a web front-end exposing the model annotations for visualizations. Currently, we provide 2 services, BIST dependency parsing and NER annotations. We also provide a template for developers to add a new service.
