What are the different types of summarization?

There are mainly two types of summarization: extractive and abstractive. Extractive summarization selects key sentences from the text, while abstractive summarization generates new sentences to convey the main ideas.

Can you give me examples of each type?

Sure! For extractive summarization, a summary might include sentences directly from the text, like quotes. For abstractive summarization, it might rephrase the content, such as saying 'The study shows significant results' instead of quoting the exact findings.

Which type is more commonly used in AI applications?

Extractive summarization is often used in AI applications because it's simpler and requires less complex language understanding. However, abstractive summarization is gaining popularity for its ability to create more coherent summaries.

What are some challenges in abstractive summarization?

Challenges include ensuring the generated text is coherent, maintaining factual accuracy, and avoiding repetition. It's a complex task that requires advanced natural language processing.
