Description
Lia is a Memory-Based Lemmatiser for Afrikaans, developed with
the Tilburg Memory-Based Learner (TiMBL). Lia takes any
Afrikaans word as input and produces the linguistic correct lemma
of the word as output. For example, the inflected word-forms
“hondjie” (‘puppy’) and “bote” (‘boats’) will be respectively
lemmatised as “hond” (‘dog’) and “boot” (‘boat’).
Version 1.0 Beta enables the user to specify different algorithm
and parameter settings for optimal performance in terms of
linguistic accuracy, classification speed and memory usage.
Groenewald (2005) reports that Lia achieves a linguistic accuracy
figure of 91,11% when trained with a dataset consisting of 56,000
words.
