They represent different approaches which distinguish with theoretical and practical comprehension of argument problems. Informal study of argument is one of the approaches. The key reason of its appearance was the criticism of formal logic in the late 20th century. Researchers consider the argument from the different point of view. Formal dialectics and pragma-dialectics were based on dialectics. Contemporary rhetorical theories of argument were created on the rhetorical grounds; theory of speech acts on the basis of practical philosophy etc.. This paper is devoted to some theoretical problems of informal logic which was formed on the logic background in the late 70＇s. In spite of numerous papers, books, and text-books on informal logic published over the last thirty years, logicians has not achieved consensus so far on many issues. Among the numerous problems are： what is the subject matter of informal logic？ Does informal logic belong to the realm of logic？ Is it applied epistemology？ What is a real argument？ And what are the criteria for evaluating of such arguments？展开更多

Although OWL-S has given semantics to concepts by ontology technology, it gives no semantics to control-flow and data-flow. This paper presents a formal semantics framework for OWL-S sub-set, including its abstraction, syntax, static and dynamic seman-tics by rewrite logic. Details of a consistent transformation from OWL-S SOS of control-flow to corresponding rules and equations, and dataflow semantics including “Precondition”, “Result” and “Binding” etc. are explained. This paper provides a possibility for formal verification and reliability evaluation of software based on SOA.展开更多

The author has continued investigating the extraordinary (paradigm-breaking) hypothesis of formal-axiological interpreting Newton’s mathematical principles of natural philosophy and, thus, has arrived to discrete mathematical modeling a system of formal axiology of nature by extracting and systematical studying its proper algebraic aspect. Along with the proper algebraic machinery, the axiomatic (hypothetic-deductive) method is exploited in this investigation systematically. The research results are the followings. 1) The Third Newton’s Law of mechanics has been modeled by a formal-axiological equation of two-valued algebraic system of metaphysics as formal axiology. (Precise defining the algebraic system is provided.) The formal-axiological equation has been established (and examined) in this algebraic system by accurate computing compositions of relevant evaluation-functions. Precise tabular definitions of the evaluation-functions are given. 2) The wonderful formula representing the Third Newton’s Law (in the relevant physical interpretation of the formal theory Sigma-V) has been derived logically in Sigma-V from the presumption of a-priori-ness of knowledge. A precise axiomatic definition of the nontrivial notion “a-priori-ness of knowledge” is given. The formal derivation is implemented in strict accordance with the rigor standard of D. Hilbert’s formalism;hence, checking the formal derivation submitted in this article is not a difficult task. With respect to proper theoretical physics, the formal inference is a nontrivial scientific novelty which has not been discussed and published elsewhere yet.展开更多
