Outline of Final Research Achievements

In this research, for documents submitted to social media, we proposed the following visualization methods: 1) bipartite graphs of product review sentences, 2) time-series documents such as news articles, 3) citation relations network of academic papers, 4) similar tweets on products graph, 5) trend word burst. Many evaluation documents posted to social media include not only the diverse opinions of users but also the needs for products. By visualizing evaluation points and user needs as an axis, it is possible to present useful information for making decisions on the service provider side and for making decisions when consumers buy products.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は,大量の評価文書を効果的かつ適切に可視化することでその全体像を把握し,さらに各評価文書へのアクセシビリティを向上させるための方法論である.ここで,効果的かつ適切な可視化とは,評価観点の類似性や評価極性,レビュアーの専門性などを考慮したスコアにより座標を決定することを意味する.この成果により,レビューサイトユーザの意思決定支援だけでなく,商品開発側の企業にも有用な情報発見が容易となることが期待される.さらに,これらの技術を一般化させ,インターネット上にある大量の文書データの整理,アクセシビリティ向上への貢献も十分期待できる.
