An example of a non-semantic identifier is:

A non-semantic identifier is one that does not convey any meaningful information about the item it represents. In the context of health information management, non-semantic identifiers are typically arbitrary and do not include any intrinsic meaning that helps to describe the associated data.

The option that represents a non-semantic identifier is the numeric sequence "83119." This number does not contain any information that relates to the subject; it’s simply a random identifier that could refer to anything and does not provide any context or semantics about what it represents.

In contrast, other options provide identifiable context. The chart number "7382" suggests it is linked to a specific medical record, implying that it holds significance in the context of patient data. The date "1 January 2020" conveys specific temporal information that situates an event in time, which also has semantic meaning. Therefore, they both include information that describes their significance within a healthcare setting.

Thus, since "83119" stands alone without any meaningful connection to the data it may represent, it is correctly identified as a non-semantic identifier.
