What does these terms mean: Vocabulary, Ontology, Taxonomy and TopicMaps in the context of Semantic Web?
Vocabulary: A term is a named concept and a voabulary can be defined as a set of terms. Examples include: DC, SKOS, FOAF, PRISM
Taxanomy: A taxonomy is a hierarchical categorization of concepts based on relatedness.
Ontologies model a little piece of existence or knowledge. For example, philosophers use ontology as a tool to describe states of being in the physical world (as opposed to discussions about metaphysics and the beyond).
From a more modern perspective, taxonomies are used to help people find and retrieve information, and ontologies are used by computer programmers to reuse and transmit data.
Controlled vocabulary: A controlled vocabulary is usually a strict list of terms that describe some kind of subject matter. From a strict point of view, a controlled vocabulary is fundamentally identical to a taxonomy. They both provide a roadmap to working effectively with a body of knowledge. A thesaurus is a special kind of controlled vocabulary, one that allows you to define synonyms, antonyms, and other relationships. (In your ecommerce store, anyone who searches for a jacket is also shown blazers and coats, for instance.)
Topic Maps: Topic maps are very similar to other categorization schemas, and even has its own international standard (ISO 13250).
