  "body": "\n## Summary\n\n**Neighborhood semantics**, also known as **Scott–Montague semantics**, is a formal semantics for modal logics. It is a generalization, developed independently by Dana Scott and Richard Montague, of the more widely known relational semantics for modal logic. Whereas a relational frame $\\langle W,R\\rangle$ consists of a set *W* of worlds (or states) and an accessibility relation *R* intended to indicate which worlds are alternatives to (or, accessible from) others, a **neighborhood frame** $\\langle W,N\\rangle$ still has a set *W* of worlds, but has instead of an accessibility relation a *neighborhood function*\n",
