descritor

Descritor is the Portuguese term for descriptor, used across information science, computing, linguistics, and data analysis to denote an attribute, label, or object that describes another resource. In English-language contexts, descriptor is the common cognate, and the term is employed similarly to identify or categorize data, objects, or phenomena.

In metadata and information retrieval, a descritor refers to a metadata element that conveys the content, context, or subject of a resource. Descriptors include keywords, subject headings, taxonomy terms, and tags, and they support indexing, search, and discovery by helping users locate relevant materials.

In computing and computer science, specifc uses appear. A file descriptor (descritor de arquivo) is a non-negative integer that an operating system uses to access an open file, socket, or input/output stream. Descriptor objects in programming languages define how attributes are accessed or stored; for example, property descriptors in JavaScript and Python's descriptor protocol control attribute access and behavior.

In data analysis and pattern recognition, a descriptor or feature descriptor is a measurable property of a data item used to characterize it, such as color, texture, or shape descriptors in image processing and computer vision. These descriptors enable comparison, retrieval, and classification of data based on quantitative features.

Overall, descritores serve as descriptive units that facilitate identification, organization, and retrieval of resources across diverse domains. See also descriptor, metadata, and feature descriptor.
