Capreolus is a toolkit for conducting end-to-end ad hoc retrieval experiments, which consist of a first stage ranking method (e.g., BM25 or RM3) followed by a neural re-ranking method.

Capreolus is organized around the idea of interchangeable and configurable modules, such as a neural reranker or a first stage searcher. Researchers can implement new module classes, such as a new neural reranker, to experiment with a new module while controlling for all other variables in the pipeline (e.g., the first stage ranking method and its parameters, folds used for cross-validation, tokenization and embeddings if applicable used with the reranker, neural training options like the number of iterations, batch size, and loss function, etc).
