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.
