Outline of Research at the Start

企業の持つビッグデータを有効に活用して新たなビジネス価値創造を行うことは,日本において急務である.またこれを産学連携で行うには,個人情報やセキュリティに配慮した上でデータ解析を行うための効果的なプラットフォームと,その運用方法の確立が重要である.本研究ではデータを持ち出さずに解析を行うプラットフォームの構築を行い,その効果的な運用方法の設計を行う.さらにライフイベントなど時間で変化する状況における顧客の消費行動を数理モデル化し,企業データを活用することによりビジネス価値創造へつなげる手法の提案を行う.

Outline of Final Research Achievements

In this research, we constructed a platform (DAPF) that enables the analysis of proprietary big data held by companies in a secure environment on a server without exporting the data outside the server. The cloud DAPF effectively conducted practical operations in a total of five projects that analyzed real data. Furthermore, the on-premise DAPF verified scalability, such as multiple analysis environments using containers and external connections via VPN.
Regarding collaborative filtering, we proposed a latent structure model that assumes multiple latent variables for various types of data, including customer and product attribute information, time information, and consumption behavior. This model integrates these data by considering the relationships between the observed and latent variables. We also evaluated the effectiveness of this model.

Academic Significance and Societal Importance of the Research Achievements

企業の持つビッグデータを大学の研究者が安全に分析を行うプラットフォームは,企業にとっては新たな価値創造の機会として,大学の研究者にとっては学術研究の発展のために大いに役立つ.この時外部へデータを漏洩させない仕組みが非常に重要である.また個人(ユーザ)が商品(サービス)に対して行う日々の消費行動について,それぞれに対する潜在変数と観測変数の関係としてある種の統合的な視点でモデル化及び推定を行う方法を示した本研究は,学術的および社会的な観点の両者に対して意義がある.
