Creating Annotations through Critical Analysis of Original research (CACAO) is a competition for teams around the world to improve the functional annotation of genes and gene products. Competitions opened in 2024. Join us by registering.

The is a platform for hosting CACAO competitions with the purpose of creating high-quality Gene Ontology annotations that can be contributed back to the Gene Ontology Consortium. The Gene Ontology project provides a valuable mechanism for standardization of annotation of gene products from different organisms. This is important for making annotation computable, and for facilitating data mining across different genomes. The rationale for Gene Ontology is well described at

The is not an official product of the Gene Ontology consortium.
