|
|
CLD2 probabilistically detects over 80 languages in Unicode UTF-8 text,
|
|
either plain text or HTML/XML. Legacy encodings must be converted to valid
|
|
UTF-8 by the caller. For mixed-language input, CLD2 returns the top three
|
|
languages found and their approximate percentages of the total text bytes
|
|
(e.g. 80% English and 20% French out of 1000 bytes of text means about 800
|
|
bytes of English and 200 bytes of French). Optionally, it also returns a
|
|
vector of text spans with the language of each identified. This may be
|
|
useful for applying different spelling-correction dictionaries or
|
|
different machine translation requests to each span. The design target is
|
|
web pages of at least 200 characters (about two sentences); CLD2 is not
|
|
designed to do well on very short text, lists of proper names, part
|
|
numbers, etc.
