In this paper we explore a class of belief update operators, in which the definition of the operator is compositional with respect to the sentence to be added. The goal is to provide an update operator that is intuitive, in that its definition is based on a recursive decomposition of the update...

It is an extremely popular view among logicians and some linguists (McCawley, Hurford) that there are two distinct or's in English - an \"inclusive\" and an \"exclusive\". It seems equally popular among lexicographers, experts on proper usage, and some linguists (R. Lakoff) that there is only...
