To solve this problem, we propose an account that codes errors of learners explicitly. Using a particular extension of classical feature logic (by introducing a designated error feature) it is possible to code errors of the language learner. We will present an algorithm that computes the unification of two feature structures for such an extension. Furthermore some properties of the algorithm and an evaluation will be presented. |
