Editing Text corpus (section)

== Overview ==

A corpus may contain texts in a single language (''monolingual corpus'') or text data in multiple languages (''multilingual corpus'').

In order to make the corpora more useful for doing linguistic research, they are often subjected to a process known as [[annotation]]. An example of annotating a corpus is [[part-of-speech tagging]], or ''POS-tagging'', in which information about each word's part of speech (verb, noun, adjective, etc.) is added to the corpus in the form of ''tags''. Another example is indicating the [[Lemma (morphology)|lemma]] (base) form of each word. When the language of the corpus is not a working language of the researchers who use it, [[interlinear gloss]]ing is used to make the annotation bilingual.

Some corpora have further ''structured'' levels of analysis applied. In particular, smaller corpora may be fully [[Parsing|parsed]]. Such corpora are usually called [[Treebank]]s or [[Treebank|Parsed Corpora]]. The difficulty of ensuring that the entire corpus is completely and consistently annotated means that these corpora are usually smaller, containing around one to three million words. Other levels of linguistic structured analysis are possible, including annotations for [[Morphology (linguistics)|morphology]], [[semantics]] and [[pragmatics]].
