| Description | The database of the Information System of Masaryk University contains all important data about students and their studies, courses, teachers or the management of the university. For analytical purposes, we have decided to implement a new web based tool for data mining (DM) and Machine learning (ML) connected to a data-warehouse fulfilled with educational data - Excalibur. This tool incorporates some standard DM and ML methods from the spread open-source tools. It is capable to visualise the data and the results. Excalibur has been employed in projects dealing with educational data several times. The most successful project considered with improving the classification of study-related data through social network analysis. The network was created from the weighted relations among students. The highest accuracy 97.7% was achieved using IB1 method. |
