目的と趣意

国土交通省として初となるデータコンペを開催します。本コンペでは、国土交通省が整備するオープンデータ「国土数値情報」と民間企業のデータを活用し、不動産の賃料・賃貸価格の予測モデルを構築していただきます。

GIS データのひとつである「国土数値情報」は、整備開始より50年、一般公開して20年以上の歴史を持つ国土に関する基礎的な地理空間情報です。約190の項目から構成され、公的情報を原点とし、検査基準を設けることで高い品質を確保し信用ある情報として利用が可能です。 近年は民間企業での利用も拡大しており、年間ダウンロード数は200万件以上(令和5年度)となっています。
そのような状況下で国土交通省では、令和5年10月に「今後の国土数値情報の整備のあり方に関する検討会(※)」を設置し、より多くの方に便利に利用いただくために整備方針を議論してきました。

重要なインフラデータである国土数値情報を、デジタル技術・データ活用における社会全体の生産性向上に貢献できるよう、より開かれた・使われるデータへの転換を進めています。

そのためにも多様なニーズや、より多くのユーザーの皆様に知っていただき、活用していただくために本コンペを開催することとなりました。

※参考:国土交通省 今後の国土数値情報の整備のあり方に関する検討会


課題

提供する国土数値情報や民間企業のデータ等を活用し、不動産の賃料の予測モデルを構築してください。なお、本コンペティションの目的から国土数値情報の利用は必須とします。

評価指標

  • 評価指標として「RMSE(Root Mean Square Error)」を使用します。
  • RMSEは予測値と実際の値の差の二乗平均の平方根を取ったもので、予測精度が高いほどRMSEの値が小さくなります。
  • 予測値はある年月におけるある物件の賃料(単位は円)とします。



入賞者決定の流れ

  1. コンテスト最終日までの評価(暫定評価)は評価用データセットの一部で評価し、コンテスト終了後の評価(最終評価)は評価用データセットの残りの部分で評価します。リーダーボードはコンテスト終了時に自動的に最終評価に切り替わり、それを元に最終順位を決定します。このため、開催中と終了後では順位が大きく変動する場合もあります。
    *投稿ファイルは最大2つまで選択可能で、最終評価のスコアの高いファイルが自動的に採用されます。
  2. スコアが同値の場合は、リーダーボードでは早い日時でご応募いただいた参加者を上位とします。
  3. 最終評価による順位が上位の方を入賞候補者とし、事務局から連絡いたします。
  4. 入賞候補者には、「国土数値情報の利用に関する具体的な方法と効果」についてレポート提出していただきます。また、必要に応じて、個別に連絡させていただき、作成したモデルの提出を求める場合もございます。
  5. 候補者及び、その提出レポートが下記いずれかに該当する場合は、入賞の資格を失います。
    • 事務局からの手続き上の連絡・要求に対して指定された期限内に対応しない
    • 参加条件やルールを満たしていない
    • 表彰式@G空間EXPOまたは振り返り会に参加できない
    • その他、事務局が不当と判断した場合
  6. コンペティションの趣旨に則っていることを確認できた方の中から、入賞者及び順位を確定します。

*入賞候補者が入賞資格を失った場合は、最終スコアが次点の方が繰り上がり、新たな入賞候補となります。
*不正が発覚した場合は、SIGNATE独自の裁量により、メダル・ポイントが付与されない場合があります。
