近年来,随着位置服务的迅速发展,位置地图作为一种新型的地图产品,相比一般地图的内容发生了明显的改变,从而拓展了位置地图的研究领域和适用范围。为此,首先,本文通过情境理论,分析了其与位置地图之间的联系,指出情境建模在位置服务特别是位置地图应用中的重要意义;然后,针对目前的情境模型在移动地图服务中存在不同情境信息之间关联度不强、情境推理难以实现的问题,重点剖析活动信息在情境建模中的重要地位,提出了活动分层的位置地图情境三层模型,研究了活动模型、行为模型和情境信息模型的研究内容及特点,并进一步分析了活动模型与不同行为、行为模型与多种情境信息之间的相互关系,利用形式化描述语言(本体)建立了位置地图情境模型的逻辑结构;最后,以用户去机场登机为例,验证了本文提出的位置地图情境建模的过程和方法。

In recent years, with the rapid development of location-based services, significant changes have taken place on location maps which are considered as new map products in research context compared with the general map. Those changes expand location map’s research areas and scope. This paper is mainly divided into three parts. First of all, it analyzes the relationship between context theory and location map, and points out the significance of context theory in location services especially in the application of location map. Then, it develops the context model, which has two main problems in mobile services: one is that different context information is not relevant, the other is that it is difficult to realize the context inference. So we should analyze the role of activity information in context modeling according to its importance. Also it establishes the logical structure of the location map’s context model by using the formal description language “ontology”, proposing the three-layer model of location map which is based on active layer, researching the content and features of activity model, behavior model and context information model, and giving further analysis on the relationships between activity model and different behaviors as well as the relationships between behavior model and various context information. Finally, this paper gives an example about a user’s check-in behavior at the airport to validate the process and methods of location map’s context model that described above.
