对SView的一些想法 程龚 (gcheng@nju.edu.cn)

什么是浏览？（它和搜索有什么区别？） Erran Carmel et al. Browsing in Hypertext: A Cognitive Study. IEEE Trans. SMC 22(5), 1992. Marchionini, 1987 Browsing = informal search characterized by the absence of planning. Marchionini & Shneiderman, 1988 Browsing = exploratory information seeking. Appropriate for ill-defined problems and for exploring new task domains. Bates, 1989 Browsing = the query itself is continually shifting.

Browsing strategies Scan-Browse: scanning to evaluate information for interestingness. Review-Browse: reviewing to integrate information into browser’s mental model. Search-Oriented Browse: planning search goals, scanning to find relevant information, and reviewing this information to integrate it. 需求的明确程度不同

语义Web浏览有什么新特征？ WHAT to browse HOW to browse dereference + integration + reasoning HOW to browse fixed  flexible + efficient

SView 0.2 回顾 more and better integrated data, grouping & ranking, visualization, … quality control, collecting & reusing, … semantic search, … semantic navigation, … semantic query suggestion, …

SView 0.4 设想 more and better integrated data, grouping & ranking, visualization, … quality control, collecting & reusing, … semantic search, … semantic navigation, … semantic query suggestion, …

SView 0.4 设想 (续) 第三方数据的发现与汇集 琳琅满目：提供尽可能多的数据源选项 (Falcons, Sindice, …) 丰俭由人：支持按需选取 童叟无欺：清晰地说明来源 more and better integrated data, grouping & ranking, visualization, … quality control, collecting & reusing, … semantic search, … semantic navigation, … semantic query suggestion, …

SView 0.4 设想 (续) 异构数据的集成 里应外合：外部服务 (ObjectCoref, sameAs, …) + Pay-as-you-go (隐式用户反馈) more and better integrated data, grouping & ranking, visualization, … quality control, collecting & reusing, … semantic search, … semantic navigation, … semantic query suggestion, …

SView 0.4 设想 (续) 信息的呈现与交互 各司其职：view store (开发者创建 + 用户安装配置 + 适用时呈现) 异曲同工：统一的浏览模型 + 缤纷的交互方式 more and better integrated data, grouping & ranking, visualization, … quality control, collecting & reusing, … semantic search, … semantic navigation, … semantic query suggestion, …

SView 0.4 设想 (续) 知识的收藏与重用 面面俱到：knowledge management (bookmark, integration, export) and sharing more and better integrated data, grouping & ranking, visualization, … quality control, collecting & reusing, … semantic search, … semantic navigation, … semantic query suggestion, …

Applications using open data SView 0.4 设想 (续) SView在语义网应用技术体系中的定位 Applications using open data Search engines … SView SNS Data index Mapping index …

SView 0.4 设想 (续) 角色定位 SView：管理、集成数据，查询，推理 (等苦差事) View开发者：呈现信息 用户：消费信息、配置、反馈

SView 0.4 设想 (续) 技术挑战 多源数据存取 隐式用户反馈 view store及浏览模型 个人知识管理
