Semantic web technologies to automate searching for geospatial data

摘要

This paper presents Semantic Web technology for the oftentimes difficult task of searching for government-produced geospatial data. We present a conceptual model that takes a task-based approach, and we formalize relationships between types of tasks, including emergencies, and types of data sources needed for those tasks. We explore the abilities and limitations of Semantic Web languages, tools, and rule engines.
