Use

Working with corpus

import elotl.corpus

Listing available corpus

print("Name\t\tDescription")
list_of_corpus = elotl.corpus.list_of_corpus()
for row in list_of_corpus:
    print(row)

Output:

Name		Description
['axolotl', 'Is a Spanish-Nahuatl parallel corpus']
['tsunkua', 'Is a Spanish-otomí parallel corpus']

Loading a corpus

If a non-existent corpus is requested, a value of 0 is returned.

axolotl = elotl.corpus.load('axolotlr')
if axolotl == 0:
    print("The name entered does not correspond to any corpus")

If an existing corpus is entered, a list is returned.

axolotl = elotl.corpus.load('axolotl')
for row in axolotl:
    print(row)

[
    'Hay que adivinar: un pozo, a la mitad del cerro, te vas a encontrar.',
    'See tosaasaanil, see tosaasaanil. Tias iipan see tepeetl, iitlakotian tepeetl, tikoonextis san see aameyalli.',
    '',
    'Adivinanzas nahuas'
]

Each element of the list has four indices:

• non_original_language
• original_language
• variant
• document_name

tsunkua = elotl.corpus.load('tsunkua')
  for row in tsunkua:
      print(row[0]) # language 1
      print(row[1]) # language 2
      print(row[2]) # variant
      print(row[3]) # document
