论文摘要
本文提出了一个刻面信息探索模型,该模型通过提供交互式小部件中的数据属性的图形表示来支持地理图的粗粒和细粒度的聚焦。提出的方法基于稀疏和嘈杂数据集中的数据探索的有效尺寸的提议,以及(ii)基于支持数据可视化,基于类别探索,基于类别的信息隐藏和跨度的结果,该搜索上下文的交互表示,基于搜索上下文的交互式表示,基于搜索上下文的交互式表示,基于搜索上下文的交互式表示,基于搜索上下文的交互式表示,对持久地理图的多类别投影进行了搜索上下文的交互式表示。我们的模型与地理知识的语义表示的集成支持了从异构数据源检索到的信息,例如公共开放数据和OpenStreetMap。我们在OnTOMAP协作Web GIS中与用户评估了我们的模型。实验结果表明,在用多个数据类别填充的地理地图上工作时,它在用户性能和经验方面都优于基于类别的地图投影和传统的刻面搜索工具(例如复选框)。
This paper proposes a faceted information exploration model that supports coarse-grained and fine-grained focusing of geographic maps by offering a graphical representation of data attributes within interactive widgets. The proposed approach enables (i) a multi-category projection of long-lasting geographic maps, based on the proposal of efficient facets for data exploration in sparse and noisy datasets, and (ii) an interactive representation of the search context based on widgets that support data visualization, faceted exploration, category-based information hiding and transparency of results at the same time. The integration of our model with a semantic representation of geographical knowledge supports the exploration of information retrieved from heterogeneous data sources, such as Public Open Data and OpenStreetMap. We evaluated our model with users in the OnToMap collaborative Web GIS. The experimental results show that, when working on geographic maps populated with multiple data categories, it outperforms simple category-based map projection and traditional faceted search tools, such as checkboxes, in both user performance and experience.
