(1) Documents for Experiments

Here we use the test collection BMIR-2 (Kitani 1998) registered to TREC for information retrieval. This collection is composed of documents, queries and their results. The documents comprise 5,079 articles from "Mainichi Newspaper" in the fields of economics or engineering. The queries have a unique format of "Retrieve articles on X," where several noun phrases are given for the variable X.
