What does labeler mean?
A labeler is a person or device that applies labels to things, identifying or describing them. A postal worker, factory employee, or office worker may act as a labeler by writing names, addresses, prices, or other information onto objects and packages. The word also refers to machines that print or attach labels automatically, as well as to people who annotate digital records for data analysis. In these technical contexts, labeling provides categories or descriptive information that make information easier to identify, sort, search, or interpret. The term is especially common in manufacturing, retail, logistics, computing, and data science. Although it is sometimes shortened to “labeler,” the full word is useful when distinguishing the person or machine from the more general act of labeling and from the label that results.
A person who applies labels or assigns names, categories, or descriptions to objects or information.
"The labeler wrote the patient's name on the specimen container."
In data science, a labeler may annotate examples according to a defined set of categories.
A machine or device that applies labels to objects, often by printing or attaching them automatically.
"The labeler printed a price tag for every item on the shelf."

From tagging luggage to annotating data, a labeler turns an ordinary object into something categorized and identifiable.
