An Information Infrastructure for Comparing Accessibility Regulations and Related Information from Multiple Sources

This paper describes a research project that addresses the difficulties in dealing with regulatory documents such as national and regional codes. These documents tend to be voluminous, heavily cross-referenced, possibly ambiguous and even conflicting at times. There are often multiple documents that need to be consulted and satisfied; however it is a difficult task to locate all of the relevant provisions. In addition, sections dealing with the same or similar conceptual ideas sometimes lay down conflicting requirements.
