| 摘 要： | 情境在移动位置服务领域起到融合多源时空数据、模拟地图使用情形及获取用户空间需求的作用。根据作者早期建立的位置地图情境模型,本文基于活动理论构建了位置地图情境三层推理规则,重点描述其基本原理与方法;通过形式化表达将情境推理的结果与位置地图表达联系起来,形成三层推理规则的解析与运行流程;以用户去机场登机为例,假设2种不同情形,验证5种情境事例。实验结果表明,本文的情境推理方法简洁、可操作性强,为进一步研究智能化地图服务提供参考和借鉴。

Rule Based Location-map Context Reasoning Construction and Case Analysis |

| Abstract: | Context in mobile location services can combine with multi-source time-space data,to simulate map-using context and guide space requirements for users.Used of the built model of the map context in the early research and based on the activity theory three-layer reasoning rules of location-map context,first of all the basic principle and method were described in detail.Secondly,translating and operating process of the three-layers reasoning rules were formed by relating results of context reasoning to the location map representation with formal expression.Finally,taking the boarding activity in the airport as an example,two kinds of different contexts were assumed and five kinds of contexts were validated.Experimental results showed that the context reasoning method,with its simplicity of reasoning and its excellent operation performance,can offer reference for further intelligent map services. |
