The goal of the OpenCLIR (Open Cross Language Information Retrieval) Challenge is to develop methods to locate text and speech content in “documents” (speech or text) in low-resource languages, using English queries. This capability is one of several expected to ultimately support effective triage and analysis of large volumes of data, in a variety of less studied languages. Successful systems will be able to adapt to new languages and new genres.
The OpenCLIR Challenge was created out of the IARPA (Intelligence Advanced Research Projects Activity) MATERIAL (Machine Translation for English Retrieval of Information in Any Language) program, which encompasses more tasks, including domain classification and summarization, and more languages and query types. Also see the NIST's MATERIAL page. The purpose of OpenCLIR is to provide a simplified, smaller scale evaluation open to all.
The first OpenCLIR, OpenCLIR19, took place in January/February 2019. Details can be found in the evaluation plan linked under Documentation below.
OpenCLIR19 planned on declaring a winner in two separate categories, text and audio data, with a monetary award for the winner of USD 10,000 in the text category and USD 20,000 in the audio category. Please see the documentation below for more details and rules regarding the prizes.
The winners of the OpenCLIR19 Challenge were announced by IARPA on November 8, 2019 in this Tweet.
