Logic in semantic analysis

Logic in semantic analysis

1. Helful to understand how computers work

2. The semantic relations between sentences...

   • sometimes, the result of using connectors
   • Others the result of their syntactic structure
   • Trying to represent these relations takes us to logic.

3. Conceptual tools used in logic

   • Propositional calculus or propositional logic
   • Predicate calculus or predicate logic
   • The construction of truth tables

4. Formal semantics

   • Usually refers to the approach that uses logic in semantic analysis.

   • Differentiation between sense and reference
     • Proposed by Frege. He later relates this differentiation to the concept of truth.
       • According to Frege
         • The value of a sentence is its truth value
         • Its sense is what he calles gedanke or objective thought.
     • Two groups of theories according to Saeed: Brandley and Swartz
       • For representational theories, semantic analysis involves discovering the conceptual structure which underlies language.
       • For denotational approaches, semantic analysis is seen inconnection with the notion of truth.
         • The search for meaning is the search of how the symbols of a language relate to reality.
       • For formal semantics based on denotational approaches, meaning is arrived at from a communicative perspective.
   • Some scholars have supported the idea that the world can be better understood anc better managed thanks to the handling of senses wich link the mental world and the real world.
   • Some problems affecting semantics in general
     • How to deal with the problem of context
       • To what extent it affects meaning, which cannot be easily inserted into the framework of logic...

5. Logicians hold that meaning is given not by representations in the mind of the speaker and hearer but by the truth conditions by which the sentence is made true.
