Lingala Diacritic Correction

Submitted by Guy on Mon, 2009-04-27 12:45

http://lingala.svn.sourceforge.net/
Description: 

The problem with using web texts for many languages is that many people do not have the ability to enter diacritics or characters from extended
character sets from their keyboard, and so they simply leave them off (and so Lingala "likɔngá" becomes "likonga"), or use incorrect diacritics
(e.g. using acute/grave in place of the macron in Hawaiian, Maori, etc.). Information is usually lost in this conversion, and indeed most languages
that use diacritics have many pairs of words that differ only in diacritical marks; these distinctions are lost when texts are written in plain ASCII.
The aim of charlifter is to undo this lossy conversion, and "lift" the text back to its proper form.

Automatic Diacritic Restoration for African Languages

Submitted by Guy on Tue, 2007-10-23 12:16
The orthography of many African languages includes diacritically marked characters. Falling outside the scope of the standard Latin encoding, these characters are often represented in digital language resources as their unmarked equivalents. This renders corpus compilation more difficult, as these languages typically do not have the benefit of large electronic dictionaries to perform diacritic restoration.

This is a demonstration system for a diacritic restoration method that is able to automatically restore diacritics on the basis of local graphemic context. It is based on the machine learning method of Memory-Based learning. We have applied the method to the African languages of Cilubà, Gĩkũyũ, Kĩkamba, Maa, Sesotho sa Leboa, Tshivenḓa and Yoruba.

You can find more information on this system in this paper

Select a language and enter the word or sentence you want to restore diacritics for.
Cilubà (e.g. mutekete)
Gĩkũyũ (e.g. nituronire)
Kĩkamba (e.g. ningulilikana)
Maasai (e.g. oltunani)
Sesotho sa Leboa (Northern Sotho) (e.g. swanetse)
Tshivenḓa (e.g. tshiswitulo)
Yoruba (e.g. isinku)

Submitted by Guy on Thu, 2007-10-11 13:05

This demo showcases a part-of-speech tagger for Northern Sotho. It retrieves the morpho-syntactic categories for words in a sentence. It uses MBT, the memory-based tagger trained on a relatively small annotated corpus.

Version1: Ocotober 10 2007 (20k tokens training set)
Version2: December 8 2007 (35k tokens training set)

Type in the text you want to tag (2,500 character limit)
Example: Motho ge a sa tseba o swanetše go dumela seo gore bao ba tsebago ba mmotše.
