Concept Pointer Network for Abstractive Summarization
Table 3: Abstractiveness: percentage of novel n-grams on Gigaword dataset.
['Models', 'Novel  [ITALIC] n-gram (%) 1-gram', 'Novel  [ITALIC] n-gram (%) 2-gram', 'Novel  [ITALIC] n-gram (%) 3-gram']
This result demonstrates a further advantage of our model in producing new and abstract concepts. Our model is designed to improve semantic relevance and promote higher abstraction. More generated summary examples can be found in Appendix B.
