Weighted archetypal analysis of the multi-element graph for query-focused multi-document summarization

作者：

Highlights：

• We formalize the problem of Q-MDS as the weighted archetypal analysis problem.

• The method incorporates the query information into the archetypal analysis.

• We examine the method on several input matrix modeling configurations.

• The best results are achieved using the multi-element graph model.

• Experimental results show that the method is an effective summarization method.
