In language learning, vocabulary is very important. Studies have shown that the dictionary is used very often in a written comprehension task. However, its utility is not always obvious. In this paper we discuss the improvements electronic dictionaries can provide compared to classical paper ones. In lexical access, they help the learner by making the relevant information selection and research easier and then improve the efficiency of usage. Our system, Alexia, contains specific lexical information for learners. In lexical production, computers gives us large possibilities with automatic processing. We will see how we use an analyser and a parser in order to make pedagogical new style activities
