导航地图情境建模

目前，尽管形形色色的导航地图产品已经成为人们日常出行的必备帮手，但是实用性不强、效率偏低是普遍存在的一种现象，严重降低了人们对地图的信任程度。为此，本文引进情境理论，通过分析其与导航地图之间的联系，指出情境建模在沟通用户、环境与设备之间作为桥梁的重要意义，并将活动从一般情境信息中剥离出来，确定了导航地图情境建模基本原理，从通用情境信息建模和导航活动建模2个方面详细阐述了导航地图情境建模的方式与方法，为后续研究情境推理与表达奠定基础。

Context of the navigation map

At present, various navigation map products have been necessary for people’s daily travel, but they have a common phenomenon of inapplicability and low efficiency, and it has affected the level of people’s trust on the map. This paper introduces context theory and points out the significance of context modeling in connection user, environment and devices by analyzing its connection with navigation map. Separating activities from the general contextual information and determining the basic principles of navigation map context modeling. Furthermore, it expounds the ways and the means of navigation map context modeling through two aspects of the general context information modeling and navigation activities modeling, providing the foundation for further study of context reasoning and expression.
