The current study examined the automated course preferences of teachers using document clustering. Data regarding teachers’ course preferences and course outlines were collected and preprocessed for further analysis. Two separate clustering solutions were generated for teachers and courses datasets. The clustering solution for teachers contained clusters of similar faculty members grouped together on the basis of their course preferences and courses taught by them in previous years. The clustering solution generated for courses contained the list of course outlines of assigned courses. Good quality clusters for both teachers and courses were generated using K-means clustering method in CLUTO software package. The generated clustering solutions were mapped for automated generation of course preferences for each teacher in the dataset. Precision, Recall and F-measure values were also reported and they indicated promising results.

This paper presents an approach to the automated design of the initial conceptual database model. The UML activity diagram, as a frequently used business process modeling notation, is used as the starting point for the automated generation of the UML class diagram representing the conceptual database model. Formal rules for automated generation cover the automatic extraction of business objects and business process participants, as well as the automatic generation of corresponding classes and their associations. Based on these rules we have implemented an automatic generator and evaluated it on a real business model.

Automatic text summarisation is the process of creating a summary from one or more documents by eliminating the details and preserving the worthwhile information. This article presents a single/multi-document summariser using a novel clustering method for creating summaries. First, a feature selection phase is employed. Then, FarsNet, the Persian WordNet, is utilised to extract the semantic information of words. Therefore, the input sentences are categorised into three main clusters: similarity, relatedness and coherency. Each similarity cluster contains similar sentences to its core, while each relatedness cluster contains sentences that are related (but not similar) to its core. The coherency clusters show the sentences that should be kept together to preserve the coherency of the summary. Finally, the centroid of each similarity cluster having the most feature score is added to an empty summary. The summary is enlarged by including related sentences from relatedness clusters and excluding similar sentences to its content iteratively. Coherency clusters are applied to the created summary in the last step. The proposed method has been compared with three known existing text summarisation systems and techniques for the Persian language: FarsiSum, Parsumist and Ijaz. Our proposed method leads to improvement in experimental results on different measurements including precision, recall, F-measure, ROUGE-N and ROUGE-L.
