Purpose of the Study:

• To develop an automated feature engineering approach for extractive summarization.
• To enhance sentence representation using word embeddings and advanced neural networks.
• To improve the performance of multidocument summarization systems.

Main Methods:

• Leveraging word embeddings for automatic sentence representation.
• Developing an enhanced convolutional neural network (CNN) model termed multiview CNNs.
• Incorporating multiview learning to boost the learning capability of CNNs for joint sentence feature extraction and ranking.

Main Results:

• The proposed multiview CNNs method effectively obtains sentence features and ranks sentences.
• The system demonstrates superior performance on five Document Understanding Conference datasets.
