An E-learner's Emotion Model of Text Using: I. Fundamental Issues for a DDE Model

As technology advanced, e-learning becomes increasingly important and popular in our society. Determining how to care about the e-learnerpsilas emotional state is a vital issue. Our research concerns offering a better service to e-learners and making their experience in online learning and communication enjoyable. In this paper, which is based on literature search, we find the main emotional categories; then bring forward a novel discrete-dimensions duality emotion (DDE) model for e-learners and present the 3 characteristics of it. Finally, through statistic emotional words from the 2000 topics of BBS, we prove that the DDE model is reasonable. All those are to serve as the basis for our subsequent studies.
