具有推理能力的时空对象情境感知技术

时空信息处理正在向微观方向发展，统一考虑室内外环境是发展趋势，并且时空对象管理和处理与情境感知技术密切相关，已成为时空数据管理、物联网、普适计算、GIS等领域应用必须解决的问题。 本项目针对室内外应用环境，研究时空对象室内外统一建模、存储机制、查询语言、索引、拓扑分析操作与算法等技术，尤其是将重点在感知设备与空间对象建模、时空对象情境感知、可编程情境感知、具有情境感知能力的查询语言等方面开展深入的研究。拟建立一种支持室内外环境、感知设备部署的数据模型，提出一种基于逻辑和时空对象操作的情境感知方法，研制一个支持室内外移动对象情境感知的数据库管理系统原型系统。本项目将数据库、物联网、GIS、普适计算等技术进行交叉融合，其成果可为时空数据管理和处理等应用提供技术和支撑软件。

The processing of spatio-temporal data is developing towards the microscopic aspect and becomes a new development trend for both outdoor and indoor environments. The management of spatio-temporal objects is closely related to the context-aware technique. Such a problem has to be solved as it is essential in many application areas such as spatio-temporal data management, internet of things, ubiquitous computing and GIS. This project focuses on the application environment for both outdoor and indoor cases, and aims to investigate the following topics: a generic data model for spatio-temporal data in outdoor and indoor, the storagement management, the query language, index techniques, toplogcial operators and query algorithms. In particular, we concentrate on the following areas: the modeling of context-aware equipments and spatial objects, context-aware spatio-temporal objects, the programmable context-aware technique, and the context-aware query language. A data model supporting the deployment of context-aware devices as well as outdoor and indoor environments is to be developed. In addition, we propose a context-aware method based on logic and the operating of spatio-temporal objects, and develop a prototype database system for supporting context-aware moving objects in outdoor and indoor environments. This project studies a cross area among database, internet of things, GIS and ubiquitous computing. The research result will be served as the technical support and softwares for the management of spatio-temporal data.
