Abstractive Text Summarization

Extractive Text Summarization

A language model is tasked with summarizing the following text:

Original Text: 'The company's quarterly report, released Tuesday, showed a 15% increase in revenue, driven primarily by strong sales in the European market. However, profits were down 5% due to rising operational costs and a one-time expenditure on new factory equipment. The CEO stated that while the profit dip is a concern, the strong revenue growth is a positive indicator for the future.'

The model produces two different summaries:

Summary A: 'The company's quarterly report showed a 15% increase in revenue. However, profits were down 5%. The strong revenue growth is a positive indicator for the future.'

Summary B: 'Despite a slight decrease in profits because of higher expenses, the company experienced significant revenue growth from its European sales, suggesting a promising outlook.'
