Comparison of graphical approaches to description of conditional
independence structures. In Proceedings of WUPES`97,
January 22-25, 1997, Prague, Czech Republic, pp. 156-172.
- Two traditional classes of graphs used for description of
probabilistic conditional independence structures are undirected graphs
and directed acyclic graphs. In recent years several wider classes of graphs
have been used in literature for this purpose: general directed
graphs, chain graphs, reciprocal graphs and annotated graphs.
The aim of the contribution is to give except an overview a
rough comparison of achieved results. That means, several questions
of general interest are raised and it is mentioned which questions
are already answered.
