A computational system uses a collection of information structured as a set of pairs: {(Key_1, Value_1), (Key_2, Value_2), ..., (Key_n, Value_n)}. To respond to a new query, the system first compares the query to each Key to compute a relevance score for every pair. Based on this process, what is the distinct role of the Value components?

Match each notational component with its correct description in the context of a memory system used for information retrieval.
