Whats the difference between categorization and classification?
These are two distinct stages in information organization – first categorization, then classification. First comes the design and construction of a taxonomy, thesaurus, ontology, or faceted classification. At this stage the terms, keywords, ideas, concepts, memes, topics, facets, etc. are identified. These are the categories. However they are arranged, they are a controlled vocabulary. This process is categorization. Each node in the resulting classification scheme should provide a globally unique meme ID. Next comes the classification of content into the categories. This can be described as attaching metadata to the documents, “tagging” them with the appropriate terms or keywords. In advanced memography, they are tagged with globally unique meme IDs to support a high precision memetic search.
