Extensible Mark-up Language, or XML, is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML is often used in the context of text analytics to refer to the process of annotating texts with tags that indicate different semantic meanings.
XML can be used to store data in a self-describing format, making it easy to exchanged between different systems. When used in the context of text analytics, XML tags can be used to annotate texts with different meanings, making it easier for machines to understand the semantics of the text.
XML is just one example of a markup language. Other popular markup languages include HTML (HyperText Markup Language), which is used to format documents for display in a web browser, and SGML (Standard Generalized Markup Language), which is a more general markup language that XML was derived from.
While XML is often used in the context of text analytics, it is important to note that the term can have different meanings outside of this industry. For example, in the software development world, XML may refer to a programming language that uses tags to define data structures. In the publishing industry, XML may be used to describe a type of digital document that includes both text and images.
It is important to understand the context in which the term Extensible Mark-up Language is being used in order to avoid confusion. When used in the context of text analytics, XML refers to a markup language that is used to annotate texts with different semantic meanings. However, outside of the text analytics industry, the term may have different meanings depending on the context in which it is being used.
The purpose of a markup language is to annotate a document so that it can be read and interpreted by both humans and machines.
Markup languages use tags to annotate documents with different meaning. For example, in HTML, there are tags to indicate a heading, a paragraph, or a list. In XML, tags can be defined to annotate a document with any meaning.
