We present a new mathematical formalism, which we call modifiable temporal beliefnetworks (MTBNs) that extends the concept ofan ordinary beliefnetwork (BN) to incorporate a dynamic causal structure and explicit temporal semantics. An importantfeature ofMTBNs is that they allowportions ofthe model to be abstract and portions of it to be temporally explicit. We show how this property can lead to substantial knowledge acquisition and computational complexity savings. In addition to temporal modeling, the language ofMTBNs can be an important analytical tool, as well as temporal languagefor causal discovery.
