JSON-NLP

(C) 2019-2020 by Damir Cavar, Oren Baldinger, Joshua Herring, Anurag Kumar, Aarushi Bisht, Jagpreet Chawla, Semiring Inc.

Version 0.2

The JSON-NLP Schema is a standard middle-ware type for the transfer of NLP output from various NLP pipelines and chains to a uniform JSON format.

This project provides the JSON-NLP specification, a proposed JavaScript Object Notation (JSON) format and JSON Schema for Natural Language Processing (NLP) annotations and example use-cases for common NLP pipelines like spaCy, Stanford CoreNLP, OpenNLP, LingPipe, and so on.

The proposed schema provides an abstraction and normalization layer, and a uniform API for NLP annotations generated by various heterogeneous NLP pipelines and components.

An exhaustive list of major NLP components is provided in the whitepaper (Cavar et al., to appear 2019, see on Arxiv) that describes the different data structures that these components can generate. For the majority of these components, the output conversion to JSON-NLP is explained and discussed in the whitepaper. In addition to a detailed description of the JSON-NLP schema properties, various JSON-NLP examples are provided and discussed.

The JSON-NLP schema provides a wider annotation framework than most common NLP-pipelines might need. There are various related projects that will explain the advanced properties of the JSON-NLP format.
