Abstract(in English) | The Online Judge System (OJS) contains a wide variety of problems, and it is difficult for users to select an optimum problem for their own level of programming understanding. Therefore, we aim to support self-study by focusing on users' submitted histories in OJS and recommending problems that match learners' learning stages. In our previous study, we have developed a problem transition model by learning the submitted history and corresponding result using Long Short-Term Memory (LSTM) which is one of the deep learning model. However, it is not possible to recommend problems which is newly added to OJS. In this study, we examine the effectiveness of problem difficulty and tags as new features for problem recommendation. We used LSTM to develop the model using submitted history, which is time-series data, and evaluated it. We developed problem recommendation models in the classification and regression models, and confirmed the effectiveness of the classification and regression models. The result indicates that the classification model is effective for the problem recommendation model, and the problem difficulty and the problem tags are considered to be effective for problem recommendation model. |
