Logical Inference

Our research on human tissue discrimination methods deriving from MRI parameters is leading to the evolution of prescribed statistical methods for data screening, normalization and discrimination. These are driven by Prolog. In Prolog, sets of logical inferences...

You have applied to work at a company that does research, development, and analysis work. Although the company does not require employees to have extensive chemical experience, all applicants are tested for their ability to follow directions, heed safety precautions, perform simple laboratory procedures, clearly and concisely communicate results, and make logical inferences. 

Forward-chaining A technique in logical inference using IF-THEN rules. All possible conclusions are drawn from a list of known facts. Because each new conclusion (THEN-clause) can be used as a fact (IF-clause) to derive other conclusions, the program iterates until no new facts can be concluded. 

Interestingly, product compositions similar to those obtained from the photolytic decomposition of N-halosulphonamides are obtained from the parent sulphonamides upon reaction with the Na2S208/CuCl2 system (equation 62)139,140. The logical inference is that these reactions, too, involve the sulphonamide radical as an intermediate. However, in this system it has been observed that for N-alkyl chains, such as n-C5Hu, substitution into the C-4 position of the N-alkyl group, via a six-membered transition state, is also... 

The most important application of methods of knowledge processing on the basis of logical inferences are expert systems ... 

Alternatively we may decide to create more specific claims, perhaps that the system performs at a level that is conducive to practical operation in a clinical environment and/or with a defined degree of availability. Whatever measure is selected it should be clear and concise and, most importantly, be capable of being demonstrated within the scope of the planned CRM assessment process. In other words it should be possible to draw lines of logical inference between each claim and the arguments set out in the body of the safety case. 

The safety case should be brought to a close with a clear set of conclusions which can be logically inferred from the analysis. In particular ... 

How then do we carry out the logical inference from the premise and hypothesis to the conclusion This is just where rigour is required for logical precision and first we need to distinguish between necessary and sufficient conditions. 

Logic-based semantic matching of services like those written in the service description languages OWL-S and WSML exploit standard logic inferences ...
