I know of a few representation and reasoning formalisms that support the activity you mention. I have been working (with current students, former students Dr. Mark Bloemeke and Dr. Young-Gyun Kim, and my colleague, Dr. John Rose) on something called "Agent-Encapsulated Bayesian Networks" (AEBNs) for a few years (off and on). The only full paper published on the topic is [Valtorta, Kim, and Vomlel, 2002]. (See full reference below my signature.) I am attaching a table (in MS-Word) [mod: contact Marco directly for the word doc...] that summarizes some features of AEBNs and three other approaches: Multiply Sectioned Bayesian Networks (MSBNs), Multiple Entity Bayesian Networks (MEBNs), and Decentralized Sensing Networks (DSNs). You must be aware that there are serious impossibility results involving decentralized sensing (DSNs) and "merging" Bayesian networks (MSBNs) and serious practical difficulties in the approaches that try to overcome the impossibility results by making additional assumptions of independence (as in AEBNs) or relaxing the distribution requirement (as in MEBNs). The table tries to summarize this. I also attach below my signature bibliographical entries (in BibTeX) for the articles mentioned in the table. > > I kindly ask to anyone who knows relevant literature about this subject t= o > send me references.
