Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Read the article below:

Middle-of-funnel content

At this next stage, your target audience is now aware of your business and the solution you provide, and they’re interested.

They trust you enough to make slightly bigger commitments, like signing up for a webinar and engaging with longer-form content; and they’re interested enough in your offering to read brand-specific material like case studies, testimonials, and newsletter emails.

Their goal is to learn more about the solution you provide—both in general and the one specifically offered by your business.

Your goal is to educate them on your offering and set your business apart from competitors—not just with your features and benefits but with your expertise and knowledge.

Next, write a summary of what it says about Middle-of-funnel content
Response: Middle-of-funnel content includes brand-specific content that educates interested audiences that are already considering an offer.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

You are a teacher giving a lecture on text summarization techniques for a class of computer science students. Explain the difference between extractive and abstractive summarization methods, providing clear examples to illustrate how each approach works. Discuss the relative advantages and disadvantages of these two methods, considering factors such as simplicity, coherence, and informativeness. Your explanation should be detailed enough for students to understand the fundamental distinctions between these techniques.

Extractive summarization methods work by identifying and extracting the most relevant sentences or phrases from the original text to form the summary. For example, if summarizing a news article, an extractive method might select the first few sentences as an introduction, followed by a few other key sentences that cover the main points. The advantage of this approach is its simplicity, as it does not require generating new text. However, extractive summaries can sometimes lack coherence and flow since the extracted sentences may not fit together seamlessly. On the other hand, abstractive summarization methods aim to generate entirely new sentences that capture the meaning of the original text in a condensed form. Using advanced natural language processing techniques, these methods analyze the semantic content and context to produce novel sentences expressing the main ideas. While more challenging to develop, abstractive summaries can read more fluently and convey the essence concisely. However, they risk introducing factual inaccuracies or missing important details from the source text.
