NTCIR-15 Data Search

A shared task on ad-hoc retrieval for governmental statistical data

Introduction

The first round of Data Search focuses on the retrieval of a statistical data collection published by the Japanese government (e-Stat), and one published by the US government (Data.gov). We will provide a set of topics derived from questions in a community question-answering service, queries generated by users based on the topics, and relevance grades for a subset of the statistical data.
