Datamaestro module for Information Retrieval datasets

Information Retrieval Datasets

This datamaestro plugin provides easy and systematic access to information retrieval datasets. It handles automated downloading and preparation of standard IR collections, exposes them through a typed Python API, and includes efficient document stores for fast text access (file, mmap, or in-memory).
