A Linguistic Knowledge-Based Spell-Checker for Brazilian Portuguese
Starting Time: 1999
Develop an interactive isolated-word spelling-error corrector for Brazilian Portuguese that will not fail users when they are lost for words, or rather, good guesses of correction. We call this feature “utility-orientation”, which we intend to accomplish by means of massive (psycho)linguistic modeling.
This project focuses on the generation of linguistically plausible/helpful/useful suggestions of correction for a given string, presumed to be a word that has undergone some kind of recoverable, i.e. justifiable, distortion on the user’s part. Thus the detection of such a string as a spelling mistake is rather an assumption than an aim, but a very reasonable one, as we have ReGra’s vast instant-access lexicon at our disposal.
· ongoing MSc project;
· finishing up models of (chiefly linguistic) phenomena connected to spelling-error production (knowledge representation);
· specifying the architecture and prototypical correction strategy.
· coverage of a range of cognitive errors predictable on the basis of knowledge in the domains of phonetics, phonology or morphology;
· recovery of multiple errors;
· attempt at validating neologisms by assessing the morphological plausibility of unknown words and hypothesizing corresponding blocking forms;
· inference of inflections of new words that have been taught by the user.
GoSPELL's Expected Products:
· the spell-checker proper;
· valuable insights into Portuguese spelling, phonology and morphology;
· a unified computational model of word distortion in Brazilian Portuguese;
· cross-language software components for word analysis;
· an instantiation of these components for Portuguese employing…
· … represented knowledge for word and spelling analysis in Portuguese;
· cross-language architecture for both spell-checking and error correction in general.
