A Logical Inference Task is an exact deductive inference task/reasoning task that requires the production of logic-based argument (a conclusion and premises).

**AKA:**Logic-based Reasoning.**Context:****Input:**an Input Set.- Optional Input: a formal logic model.

- The Conclusion is generally meant to be previously Unobserved and Unknown.
- It can be solved by an Inferencing System that applies an Inferencing Algorithm.
- It can range from being a Deduction Task to being an Induction Task to being an Abduction Task.
- …

**Counter-Example(s):****See:**Satisfiability Task, Non-Monotonic Reasoning.

**Inference**is the process of drawing a conclusion by applying rules (of logic, statistics etc.) to observations or hypotheses; or by interpolating the next logical step in an intuited pattern. The conclusion drawn is also called an inference.- Human inference (i.e. how humans draw conclusions) is traditionally studied within the field of cognitive psychology.
- Logic studies the laws of valid inference.
- Statisticians have developed formal rules for inference (statistical inference) from quantitative data.
