is an Aggregator.
It is part of the Translator collection.
ARAX (Expander Agent) is a graph-based modular reasoning tool for translational biomedicine developed as part of the NCATS Biomedical Data Translator program. It provides a web browser user interface and TRAPI-compliant API for encoding translational biomedical questions and integrating knowledge across multiple sources. ARAX features ARAXi, an intuitive domain-specific language for specifying knowledge graph analysis workflows. The system accesses around 40 Knowledge Providers covering over 100 underlying knowledge sources and provides versatile methods for scoring and ranking result subgraphs. ARAX uses RTX-KG2 as its primary knowledge graph and supports query planning, knowledge gathering, overlay of contextual information, filtering, and result ranking through five core modules (Expander, Overlay, Filter, Resultify, and Ranker).
