In this paper we present an approach for automated evaluation of essay-writing in second language learning. While many e-learning systems make best use of learners' history, it is not clear how systems evaluate essay-writing and show scores effectively. The proposed method provides the criterion which consists of three perspectives; vocabulary size, syntax complexity and story line. The scoring method with using text mining techniques is to be used in a web system. The goal of this paper is to show the integrated method that automates evaluation in order to effectively utilize the history of essay-writing and to encourage students to raise motivation.
