Vehicle trajectory modelling is an essential foundation for urban intelligent services. In this paper, a novel method, Distant Neighbouring Dependencies (DND) model, has been proposed to transform vehicle trajectories into fixed-length vectors which are then applied predict the final destination. This paper defines problem of neighbouring and distant dependencies first time, puts forward way learn memorize these two kinds dependencies. Next, destination prediction model given based on DND...
How to apply natural language and speech technology is one of the important contents that increase intelligent degree mobile GIS improve its serving system. From system structure application demand GIS, this paper basically explained objective key techniques in discussed multi modes includes centralized mode distributed mode, perfect human-computer conversation mixed among them, speaker-dependent speaker- independent mode. Finally some primary methods, about how adopt these were synoptically...
Voice technology is one of the important contents to improve intelligence and humanization tourism service system. Combining voice technology, paper concentrates on application needs composition system to present an overall intelligent service system's framework consisting presentation layer, Web services layer, and layer. On basis, further elaborated implementation its key technologies, including interactive seamless integration multiple data sources, location-perception-based guides'...
Abstract. This paper proposed an encoding method for compressing geographical coordinates in 3D space. By the way of reducing length coordinates, it helps to lessen storage size geometry information. In addition, algorithm subdivides whole space according octree rules, which enables progressive transmission and loading. Three main steps are included this method: (1) subdividing geographic based on structure, (2) resampling all vertices models, (3) with a combination Cube Index Code (CIC)...
