This is a general framework to create arango db graphs and annotate them.

Welcome to the Corpus Annotation Graph Builder (CAG)

cag is a Python Library offering an architectural framework to employ the build-annotate pattern when building Graphs.

Official Documentation.

Corpus Annotation Graph builder (CAG) is an architectural framework that employs the build-and-annotate pattern for creating a graph. CAG is built on top of ArangoDB and its Python drivers (PyArango). The build-and-annotate pattern consists of two phases (see Figure below): (1) data is collected from different sources (e.g., publication databases, online encyclopedias, news feeds, web portals, electronic libraries, repositories, media platforms) and preprocessed to build the core nodes, which we call Objects of Interest. The component responsible for this phase is the Graph-Creator. (2) Annotations are extracted from the OOIs, and corresponding annotation nodes are created and linked to the core nodes. The component dealing with this phase is the Graph-Annotator.

This framework aims to offer researchers a flexible but unified and reproducible way of organizing and maintaining their interlinked document collections in a Corpus Annotation Graph.

Installation

Direct install via pip

The package can also be installed directly via pip.

pip install cag

This will allow you to use the module cag from any python script locally. The two main packages are cag.framework and cag.view_wrapper.
