The system is trainable and uses manually annotated corpus. We have introduced methods for evaluating the summary against other human summaries. Moreover, we used human judgment for system output, and finally we tested the system against a commercial Arabic summarization system. We selected several different Arab texts from Web sites, taking into account the difference in the content of the text, for example, the historical text and text and text scientific news ... etc.
