普适计算环境下位置模型研究进展
Research on progresses and directions of location model in ubiquitous computing
摘要
Abstract
Location model plays an important role in ubiquitous computing and the Internet of Things,which can help to im plement the fusion of physical world and information world.An overview of location models is provided.lt focuses on sever al aspects, including basic principles and approaches of location model, location reasoning, location representation methods, ontology-based models,and geospatial ontology.Especially the most popular ontology-based location models are compared and contrasted.A number of location models are developed specifically for use in pervasive computing,none of which appears to cover adequately unified concept model,rich location logics,powerful reasoning capability.A multidisciplinary intersection ap proach to researching location model, combining location theory, ontology theory, and geospatial theory, is pointed out in or der to obtain a unified location model with powerful reasoning ability.关键词
