This chapter introduces propositional logics, which consist of starting formulae called axioms and rules of inference to derive from the axioms other formulae called theorems. Axioms and rules of inference form a mathematical model of rational thinking processes; theorems are their consequences. ...
Reducing First-Order Inference to Propositional Inference 通用实例化(Universal Instantiation, UI) 定义:对于带有全称量词的句子(如 ∀x),可以通过替换变量 x 为具体的常量项(ground term)来得到新句子。 例子:原句:∀x (King(x) ∧ Greedy(x) ⇒ Evil(x))替换x 为具体的常量: King(John) ∧ Greed...
We explore connections between polyhedral projection and inference in propositional logic. We formulate the problem of drawing all inferences that contain a restricted set of atoms (i.e., all inferences that pertain to a given question) as a logical projection problem. We show that polyhedral proje...

propositional logicinferenceperformanceSpeed is a significant factor in the implementations of rule-based systems, and many inference engines slow dramatically as the size of the problem increases. Test sets such as Waltz and Manners measure the speed of first order logic inference engines. However, ...
For Markov logic , this is formally defined as follows: $$ \begin{align} arg \; \max_y P(y|x) & = arg \; \max_y \frac{1}{Z_x} exp \left( \sum_i w_in_i(x, \; y) \right) \tag{3.1} \\ & = arg \; \max_y \sum_i w_in_i(x, \; y) \tag{3.1} \end{alig...
