We equip ordered logic programs with negation as failure, using a simple generalization of the preferred answer set semantics for ordered programs. This extension supports a conven...
Abstract--The types of lexicons necessary for Transparent Intensional Logic (TIL) logical analysis will be described. We will show the algorithm for analysing the TIL verbal object...
Inconsistencies frequently occur in knowledge about the real-world. Some of these inconsistencies may be more significant than others, and some knowledgebases (sets of formulae) m...
In nonmonotonic reasoning, a default conditional has most often been informally interpreted as a defeasible version of a classical conditional, usually the material conditional...
Church's Higher Order Logic is a basis for proof assistants -- HOL and PVS. Church's logic has a simple set-theoretic semantics, making it trustworthy and extensible. We ...
