TREC Washington Post Corpus

Synopsis

The TREC Washington Post Corpus contains 608,180 news articles and blog posts from January 2012 through August 2017. It was originally used for the Common Core Track at TREC 2018 (http://trec-core.github.io/2018/ ). The initial document collection contained duplicate docids. These duplicates are removed from the filed dataset. The resulting collection contains 595,037 documents. The documents are stored in one single JSON Lines file (http://jsonlines.org/ ).

Research and Usecases

This dataset will also be used within the course of CENTRE@CLEF2019 (http://www.centre-eval.org/clef2019/ ). This track focuses on the replicability, reproducibility and generalizability of retrieval systems. We are planning to participate in the CENTRE-track.
