13 Semantic Web Phonology Linguistics Morphology Semiotics (Science of signs) Syntax (relationship between signs) Semantics (relationship between signs and meanings) Pragmatics (relationship between signs and persons) Semasiology (Science of the meaning of terms) Onomasiology ( relationships between terms) Semantic Web (structures and standards) Ontology Conceptionally generated knowledge spaces Semantic Technologies (Networking and integration prozesses) Semantic Web Terms are related to each other to form contexts. This transforms information technology in knowledge technology.

14 Semantic relationships Homonyms Ambiguity without functional relationships for example: (river or money) bank Polysems Ambiguity with functional relationships for example: (dental or architectural) bridge Synonyms Unambiguity with conceptual terms for example: Sinus list and sinus elevation
