Abstract

Learning a foreign language is a long, error-prone process, and much of a learner's time is effectively spent studying vocabulary. Many errors occur because words are only partly known, and this makes their mental storage and retrieval problematic. This paper describes how an intelligent interface may take advantage of the access structure of the mental lexicon to help predict the types of mistakes that learners make, and thus compensate for them. We give two examples, firstly a dictionary interface which circumvents the tip-of-the-tongue problem through search-by-similarity, and secondly an adaptive test generator which leverages user errors to generate plausible multiple-choice distractors.
