Masters Thesis in Computer Science: Direkt Pro l18th January 2007Supervisors: Jonas Granfeldt and groovy of South Dakota NuguesAbstractDirekt Pro l (DP) is a system for grammatic master ling. It detects, annotates and displays grammatical constructs, both correct and incorrect, in freely-written civilize texts by Swedish-speaking learners of French. It flush toilet also determine the learners developmental stage, given a text with enough identifying attributes. The scope of my last is the nal step, the classi cation of the text as being typical for a trustworthy stage, for which machine learning (ML) methods, more speci cally C4.5, LMT (Logistic Model Tree) and SVM (Support Vector Machine), start been applied. This thesis is part of a longer-term research lying-in, led by Jonas Granfeldt and Suzanne Schlyter at the Centre for languages and lit at Lund University. The research professional personject aims at increasing our com panionship regarding how Swedish- speaking learners acquire pro ciency in written French. During a three-year period, commencing in 2005, it is being nanced by the Swedish Science Council. In my look intos with an early version (1.5.2) of the pro ling system, precision and anamnesis values of a lead classi er (basic/intermediate/native), ground on sup- port transmitter machines, have reached 70 83 %. The system has also been tested with C4.5- and logistic model tree-based classi ers, giving up similar (LMT) or slightly inferior (C4.5) results.

Direkt Pro l 2.0 gives similar act even for a quintary classi er, and ternar y classi er precision and abjure is somewha! t improved as sound (up to 88 %). The uninitiate Bayes method yields a lessened further general precision/recall increase, and is much immediate than SMO (SVM) on the experiment corpus. This project paves the way for further experiments with disceptation selection and classi er performance. Contents1Introduction12Learning a Foreign Language32.1Introduction . . . . . . . . . .
