Märgistamise

Märgistamine refers to the process of applying marks, labels, or tags to objects, data, or media in order to convey information, enable identification, sorting, or processing. The term is formed from the Estonian verb märgistama (to mark) with the nominalizing suffix -mine, and is used across several domains to describe systematic labeling activities.

In manufacturing and logistics, märgistamine involves adding identifiers such as barcodes, serial numbers, or handling instructions to products, packaging, or shipments. These marks facilitate inventory management, traceability, quality control, and compliance with safety or regulatory requirements. In consumer contexts, product labeling communicates essential information such as origin, contents, and warnings.

In data processing and artificial intelligence, märgistamine is commonly known as data labeling or annotation. It consists of assigning descriptive metadata, categories, or spatial annotations (for example, bounding boxes in images) to data sets to train and evaluate machine learning models. The quality and consistency of labeling directly influence model performance, making clear guidelines and reliable annotators important.

In digital media and information management, märgistamine can refer to tagging content with keywords or metadata to improve searchability, organization, and retrieval. In linguistics and corpus work, tagging parts of speech or other annotations to text is another application, supporting research and language technology development.

Challenges include achieving consistent standards across domains, ensuring privacy when labeling sensitive data, and maintaining labeling quality and auditability. Standards and best practices in metadata, taxonomy design, and annotation protocols help mitigate these issues.
