Deduction and Inference
Are Deduction (⊢) and Inference (⊢?) the same thing? Because in the exam from 2016/17 in part 4 it is asked for Entailment and Inference, but in this situation I would have said Deduction instead of Inference. Inference for me means Equality and Tightness of Constraint networks. Maybe I got something wrong?

Context matters. In the context of formal logic, deduction and inference refer to the same thing. In the context of CSPs, inference is a different beast entirely.
