Controlled Vocabulary
Natural language can prove to be confusing because some words can be ambiguous or have multiple meanings. A controlled vocabulary is a chosen set of words that removes the confusion and ambiguity by giving users defined usage for these words.
Using a controlled vocabulary removes typing and spelling errors and provides consistency to the way compound groups of words are presented to users. The use of the controlled vocabulary is essential for the workflows for tagging images with key words and displaying groups of images in a digital asset management database.
A controlled vocabulary is created and tailored to describe the events, activities, and people surrounding the organization. The words are used to identify the content or the “aboutness” of your digital photographs, but it can be used to identify all other digital files.
