Programmatic Labeling

Programmatic labeling reduces the dependency on pure manual labor by making annotation more systematic. Large volumes of data can be labeled through labeling functions, regex patterns, business rules, or model-assisted heuristics. This is especially valuable for rapid iteration and for translating domain knowledge into code. However, the labeling rules themselves require quality control, because flawed logic can generate errors at scale very quickly. Programmatic labeling is powerful for scale, but risky if treated as blind automation.
