Keeping Things Clear
In a controlled vocabulary, we strive for disambiguation, the restriction and clarification of meaning. We want to determine and clarify what exactly is meant by each term. Reading could mean a town in England or it could be a communication process. We might have the word ‘cells’, meaning biological microsystems or electrical equipment or prison housing or other things. You can have a terrorist cell. Cell is a broadly used term, and without some kind of a modifier around it, we can’t be sure what it is exactly.
