An Intelligent Information System for Maritime Navigation Information

This paper describes aspects of an information system being constructed for intelligent information retrieval in maritime navigation applications. The system is based largely on digital nautical charts, and the construction of a taxonomy of chart features and concepts related to the maritime navigation domain is described. This taxonomy is used in formulating queries and sub-queries for dispara...

Towards Information Brokering: an ‘intelligent’ Database Navigation and Management System

In a ‘real-world’ database application the need to make available data according to the user’s requirements is very real. For that matter, the true measure of the efficacy of a database system is its ability to provide ‘intelligent’ database navigation mechanisms that can handle complex user queries for extracting pertinent and useful data from a database. Here, we propose a database applicatio...

CMU Sidewalk Navigation System: A Blackboard-Based Outdoor Navigation System Using Sensor Fusion with Colored-Range Images

We describe the CMU Sidewalk Navigation System, which can drive a vehicle in the outdoor environment of the CMU campus. The system includes all modules necessary for outdoor navigation .. modules for route planning, local path planning, vehicle driving, perception, and map data. The perception module uses sensor fusion with color and rage data to analyze complex outdoor scenes accurately and ef...

Information-based intelligent unmanned ground vehicle navigation

Sensor-centric navigation of Unmanned Ground Vehicles (UGVs) operating in rugged and expansive terrains requires the competency to evaluate the utility of sensor information such that it results in intelligent behavior of the vehicles. In this paper, we propose an entropic information metric for the above purpose where entropy is used to quantify the probabilistic uncertainty in sensor measurem...
