ISS Findings

1. Word graphs are actually applied
2. Word graphs contribute to overcoming periods of
   inactivity
3. Architects are not equally engaged in verbal
   design

SS Findings

1. SS performs better than other software, but worse
   than pen paper
2. A significant reduction of user actions compared
   to other software
3. Need for doodling

Decision Support Bayesian Networks (BN)

• BN is a formalism for performing reasoning using
  partial beliefs under conditions of uncertainty
• Case Measuring housing preferences

BN findings

1. Differences between the BN predictions and
   real-life selections decreased
2. Increase of the number of accepted suggestions
   provided by the BN

Joint Architectural Network for Urban Synergy
(JANUS)

• Public-Private collaboration
• Focus on what should be communicated instead of
  how
• Participants Architects, Contractors, Principal,
  Governmental institutes

Projects

• Digital Dormer
• Digital code checking
• Online building permits
• ..

27
Retrospective and Prospective

• DS between CS SS
• Experimental results are often not glamorous
• Designers are incapable of specifying their own
  needs
