The Public and Scientific Problem
•
•
•
•
Regulations are established to protect the public
Many organizations set regulations
Regulations greatly constrain businesses actions
Interpretation of regulations is costly and inconsistent
•
•
•
•
Regulations are written in natural language
They are often incomplete, sometimes conflicting
The objects being regulated are often encoded
Many levels of translation are needed

Applications investigated
Objectives: check compliance
• Disabled access:
– participants:
• architects, building owners, the disabled &
the federal and local governments
• Waste disposal:
– participants:
• generators, haulers, sites &
the governments – protecting us
• There are 100’s of other areas

General REGNET Process
1. Capture texts from legal and agency sources
2. Establish ontologies to formalize meaning
3. Translate texts into processable forms
– provides intermediate access
4. Extract rules in terms of applications
– validate and compare rules
5. Apply rules to design or processes
6. Display results, typically graphically, to participants

Scope and Emphasis
• To develop a formal but practical infrastructure to
enhance the access and retrieval of government
regulations
• Pilot research application focuses on regulations
for assuring, for the handicapped, accessibility to
buildings and safe egress in emergencies

Example Path Width Definition
ADAAG Definition:
4.3.3 Width. The minimum clear width of an accessible route shall be 36 in (915
mm) except at doors (see 4.13.5 and 4.13.6). If a person in a wheelchair
must make a turn around an obstruction, the minimum clear width of the accessible
route shall be as shown in Fig. 7(a) and (b).
Alternate Definition:
Variances will be allowed for
accessible route configurations
that adhere to the ergonomic
and anthropometric parameters
set forth in this document that can
be demonstrated visually, either
manually or computationally.

Recommendations to the Owner and Agencies
• Remove men’s bathroom stall partitions
• Make all rooms “Usable”
Widen door openings
Rearrange room furniture
• Alternative definition of the Accessible Route
• Alternative definitions of route components
Performance-based allowances
• Explicit Statement relating:
Accessibility to Functionality of Spaces

Section 262.11 Hazardous waste determination.
……
(a) He should first determine if the waste is excluded from regulation under 40
CFR 261.4.
(b) He must then determine if the waste is listed as a hazardous waste in
subpart D of 4 0 CFR part 261.

RegNet Research Motivations and Goals
• Research motivations
– What is an appropriate model for a information
management system for compliance checking?
– How to build such a system
– How to deal with the conflicting objectives?
• Research goal
– Developing information management frameworks
that can improve the efficiency of regulation
compliance and facilitate the compliance process.
