  While there are high-quality software frameworks for information retrieval
experimentation, they do not explicitly support cross-language information
retrieval (CLIR). To fill this gap, we have created Patapsco, a Python CLIR
framework. This framework specifically addresses the complexity that comes with
running experiments in multiple languages. Patapsco is designed to be
extensible to many language pairs, to be scalable to large document
collections, and to support reproducible experiments driven by a configuration
file. We include Patapsco results on standard CLIR collections using multiple
settings.
