Summarize the following text on the main techniques used for summarizing text:

Text summarization is the process of creating a concise and precise summary of a longer text while focusing on the main points and capturing the most important information. There are several techniques used for summarizing text, including:

1. Extractive Summarization: This method involves identifying and extracting the most important sentences or phrases from the original text and combining them to form a summary. It relies on statistical and linguistic features to determine the importance of each sentence or phrase.

2. Abstractive Summarization: This technique goes beyond extracting sentences and involves generating new sentences that capture the essence of the original text. It requires a deeper understanding of the text and the ability to paraphrase and restructure the information.

3. Topic Modeling: This approach involves identifying the main topics or themes present in the text and using them to guide the summarization process. It often involves techniques like Latent Dirichlet Allocation (LDA) or Non-Negative Matrix Factorization (NMF) to uncover the underlying topics.

4. Sequence-to-Sequence Models: These are neural network-based models that treat summarization as a sequence-to-sequence task, where the input is the original text, and the output is the summary. These models are trained on large datasets of text and summaries, learning to generate summaries that capture the most important information.

5. Graph-based Methods: These techniques represent the text as a graph, where nodes represent sentences or concepts, and edges represent relationships between them. The summarization process then involves identifying and extracting the most important nodes or paths in the graph.

The choice of technique depends on factors such as the length and complexity of the text, the desired level of abstraction, and the availability of training data. In many cases, a combination of these techniques may be used to produce high-quality summaries.

The main techniques used for summarizing text are extractive summarization (extracting important sentences), abstractive summarization (generating new sentences), topic modeling (identifying main themes), sequence-to-sequence models (using neural networks), and graph-based methods (representing text as a graph).

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: Sum up this intro Seoul for me in just one sentence: 

Seoul is an ultra-modern city filled with sleek high-rises and time-tested palaces, tempting street food vibrant shopping districts and much more. 

Whether you want to see the latest K-pop sensation, take a late-night food and drink tour, or find serenity in a spa or temple, South Korea’s capital has something to offer 24/7. Here are the best things to do in Seoul.

Taste the street food at Gwangjang Market
Street food in Seoul is beloved for its spice, variety and affordability, and there’s no better place to try it than at Gwangjang Market. Dating from the early 20th century, this covered market has gained a reputation among foodies for having some of the country’s best street snacks. 

Start with an order of tteokbokki (stir-fried rice cakes in a bright orange spicy sauce), followed by a couple of mandu (Korean dumplings) and a pajeon (savory green onion pancake). For dessert, try hotteok (a pancake filled with brown sugar and cinnamon) or bungeoppang (a fish-shaped pastry filled with sweet red bean paste). Then do it all over again.
Response: Seoul has something to do all the time, including lots of beloved street food like mandu and pajeon.

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.
