我们描述了一个概念和计算架构,称为基于知识的导航的可视化和解释的抽象(KNAVE)。KNAVE是一个独立于领域的框架,专门用于通过面向时间的原始数据和可以从这些数据中抽象出来的更高级别的基于间隔的概念,以上下文敏感的方式进行解释,总结,可视化,解释和交互式导航的任务。KNAVE领域无关的导航算子通过基于知识的时间抽象问题求解方法的本体映射到特定领域的知识库。因此,领域特定的语义驱动领域无关的可视化和导航过程。通过访问特定领域的时间抽象知识库和特定领域的面向时间的数据库,KNAVE模块使用户能够查询特定领域的时间抽象,并改变可视化的焦点,从而为不同的任务重用从领域专家获得的领域模型。对KNAVE原型的初步评价令人鼓舞。KNAVE方法对规划、监控、解释和数据挖掘等任务具有潜在的广泛影响。
We describe a conceptual and computational architecture called Knowledge-based Navigation o f Abstractions for Visualization and Explanation (KNAVE). KNAVE is a domain-independent framework specific to the task of interpretation, summarization, visualization, explanation, and interactive navigation in a context-sensitive manner through time-oriented raw data and the multiple levels of higher-level, interval-based concepts that can be abstracted from these data. The KNAVE domain-independent navigation operators are mapped through the ontology of the knowledge-based temporal-abstraction problem-solving method to the domain-specific knowledge base. Thus, the domain-specific semantics are driving the domain-independent visualization and navigation processes. By accessing the domain-specific temporal-abstraction knowledge base and the domain-specific time-oriented database, the KNAVE modules enable users to query for domain-specific temporal abstractions and to change the focus of the visualization, thus reusing for a different task the domain model that has been acquired from the domain experts. Initial evaluation of the KNAVE prototype has been encouraging. The KNAVE methodology has potentially broad implications for tasks such as planning, monitoring, explanation, and data mining.
