          <datacite:description xml:lang="ja" descriptionType="Abstract">この論文は自由回答形式で得られたデータのコーディング作業を効率的に進めるための方法を提案するものである。変数のリコードの発想を応用して大学の学校名および学科系統に関する情報を一括して数値コードに変換する方法について解説する。この論文ではデータの加工や前処理を行ううえでデータを整然データに変形することが重要であることも示す。コーディング作業の実践例を提供するために高校生調査の進路希望についての回答を利用する。</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">This paper proposes a method to enhance the efficiency of coding procedures for data obtained through open-ended survey questions. Drawing on the concept of variable recoding, it introduces a technique for systematically converting information on university names and academic disciplines into unified numerical codes. The study further highlights the importance of reshaping data into a tidy format as a crucial step in preprocessing and data management. To demonstrate the practical application of the proposed approach, the coding of responses concerning career aspirations from a survey of high school students is presented as an example.</datacite:description>
