- the term "belief networks" encompasses a whole range of different
but related techniques which deal with reasoning under uncertainty
- both quantitative (mainly using Bayesian probabilistic methods) and
qualitative techniques are used
- useful to develop knowledge based applications in domains which are
characterized by inherent uncertainty
- increasingly, belief network techniques are being employed to deliver
advanced knowledge based systems to solve real world problems
- recently used by Microsoft Office where the belief networks underlie
the help wizards
