Metadata is defined as “data that provides information about other data”. In the context of text analytics, Metadata is often used to describe the structure or content of a document, such as the author, the date created, or the topic. Metadata can also be used to describe the relationships between documents, such as which documents are similar or related.
Outside of text analytics, Metadata is often used to describe the physical characteristics of a document, such as its size, format, or resolution. metadata can also be used to describe the relationship between a document and other objects, such as who owns the document or where it is located.
Metadata is sometimes compared to other terms, such as data dictionary or schema. However, Metadata is more general than these terms, and can be used to describe any kind of data.
