Abstract
Information about public safety has become critical for government organizations, non-government organizations and citizens in general. It enables informed decisions to be made by individuals, as well as guides the creation of public policies. As with many domains, information on public safety is usually spread across different organizations, described in different formats and published at different levels of granularity and richness. In this paper, we present work done on a web-based portal that aggregates and displays public safety information for the city of Troy, New York. This portal shows how the use of semantic technologies facilitates the integration of multiple data sources with disparate characteristics. The portal demonstrates two types of functionality: First, it shows different examples of integration of public safety information through a variety of examples and visualizations. Second, it acts as a source of semantified data that third-party developers can use in their own applications.
