Outline of Final Research Achievements

In the digital transformation era, utilizing open data for various applications is an important issue. In this research, two techniques are developed; one is efficient search entities from graph-structured data consisting of relationships between data, and the other is an integration technique for data published by different organizations. On the basis of these techniques, efficient extracting data of interest becomes possible, and precise data analysis using data of multiple granularity.

Academic Significance and Societal Importance of the Research Achievements

オープンデータやデジタルトランスフォーメーションが進行している現状において,デジタル化・オープン化したデータを活用することは重要である.一方で,データを作成する組織は別々であることも多く,横断的な活用には障害が残る.本研究では,異なる組織が公開したデータの関連性に基づいたデータ統合や複雑化したデータから必要な情報を一般的な検索方法を用いて検索できるようにした.これらは今後のオープンデータ活用における基礎的な技術である
