7.6.2 Summarize Content

The following sections in this topic describe how to summarize exiting content using MySQL HeatWave GenAI:

Before You Begin

Summarize Text

To summarize text, perform the following steps:

  1. To define the text that you want to summarize, set the @text variable: 

    mysql>SET @text="TextToSummarize";

    Replace TextToSummarize with the text that you want to summarize.

    For example: 

    mysql>SET @text="Artificial Intelligence (AI) is a rapidly growing field that has the potential
to revolutionize how we live and work. AI refers to the development of computer systems
that can perform tasks that typically require human intelligence, such as visual perception,
speech recognition, decision-making, and language translation. One of the most significant
developments in AI in recent years has been the rise of machine learning, a subset of AI that
allows computers to learn from data without being explicitly programmed. Machine learning
algorithms can analyze vast amounts of data and identify patterns, making them increasingly
accurate at predicting outcomes and making decisions. AI is already being used in a variety
of industries, including healthcare, finance, and transportation. In healthcare, AI is being
used to develop personalized treatment plans for patients based on their medical history and
genetic makeup. In finance, AI is being used to detect fraud and make investment
recommendations In transportation, AI is being used to develop self-driving cars and improve
traffic flow. Despite the many benefits of AI, there are also concerns about its potential impact
on society. Some worry that AI could lead to job displacement, as machines become more capable
of performing tasks traditionally done by humans.";

  2. To generate the text summary, pass the original text to the LLM using the ML_GENERATE routine, with the task parameter set to summarization: 

    mysql>SELECT sys.ML_GENERATE(@query,
JSON_OBJECT("task", "summarization", "model_id", "ModelID", "language", "Language"));

    Replace the following:

    • ModelID: LLM to use.

    • Language: the two-letter ISO 639-1 code for the language you want to use. Default language is en, which is English. To view the list of supported languages, see Languages.

      The language parameter is supported as of MySQL 9.0.1-u1.

    For example: 

    mysql>SELECT sys.ML_GENERATE(@text,
JSON_OBJECT("task", "summarization", "model_id", "mistral-7b-instruct-v3", "language", "en"));

    A text summary generated by the LLM in response to your query is printed as output. It looks similar to the text output shown below: 

    | {"text": " Artificial Intelligence (AI) is a growing field that uses computer 
systems to perform tasks requiring human intelligence, such as visual perception 
and decision-making. Machine learning, a subset of AI, allows computers to learn 
from data without being explicitly programmed. AI is already being used in various 
industries, including healthcare, finance, and transportation. However, there are 
concerns about job displacement due to its increasing capabilities."} |

Run Batch Queries

To run multiple summarization queries in parallel, use the ML_GENERATE_TABLE routine. This method is faster than running the ML_GENERATE routine multiple times.

Note

In versions older than MySQL 9.2.1, to alter an existing table or create a new table, MySQL requires you to set the sql-require-primary-key system variable to 0.

The ML_GENERATE_TABLE routine is supported as of MySQL 9.0.1-u1.

To run the steps in this section, create a new database demo_db and table input_table: 

mysql>CREATE DATABASE demo_db;
mysql>USE demo_db;
mysql>CREATE TABLE input_table (id INT AUTO_INCREMENT, Input TEXT, primary key (id));
mysql>INSERT INTO input_table (Input) VALUES(
  CONCAT(
  'MySQL is a widely used open-source relational database management system or RDBMS that ',
  'is based on the SQL standard. It is designed to be highly scalable, reliable, and secure, ',
  'making it an ideal choice for businesses of all sizes. MySQL uses a client-server ',
  'architecture, where the server stores and manages the data, while clients connect to the ',
  'server to access and manipulate the data. The MySQL server can be installed on a variety ',
  'of operating systems, including Linux, Windows, and macOS. One of the key features of MySQL ',
  'is its support for stored procedures, which allow developers to create reusable blocks of ',
  'code that can be executed multiple times. This makes it easier to manage complex database ',
  'operations and reduces the amount of code that needs to be written. MySQL also supports ',
  'a wide range of data types, including integers, floating-point numbers, dates, and strings. ',
  'It also has built-in support for encryption, which helps to protect sensitive data from ',
  'unauthorized access. Another important feature of MySQL is its ability to handle large ',
  'amounts of data. It can scale horizontally by adding more servers to the cluster, or ',
  'vertically by upgrading the hardware.'
  )
);
mysql>INSERT INTO input_table (Input) VALUES(
  CONCAT(  
  'Artificial Intelligence or AI refers to the simulation of human intelligence in machines ',
  'that are programmed to think and act like humans. The goal of AI is to create systems that ',
  'can function intelligently and independently, exhibiting traits associated with human ',
  'intelligence such as reasoning, problem-solving, perception, learning, and understanding ', 
  'language. There are two main types of AI: narrow or weak AI, and general or strong AI. ',
  'Narrow AI is designed for a specific task and is limited in its abilities, while general ',
  'AI has the capability to understand or learn any intellectual task that a human being can. ',
  'AI technologies include machine learning, which allows systems to improve their performance ',
  'based on data, and deep learning, which involves the use of neural networks to model complex ',
  'patterns. Other AI techniques include natural language processing, robotics, and expert systems. ',
  'AI has numerous applications across various industries, including healthcare, finance, ', 
  'transportation, and education. It has the potential to revolutionize the way we live and work ',
  'by automating tasks, improving efficiency, and enabling new innovations. However, there are ',
  'also concerns about the impact of AI on employment, privacy, and safety.'
  )
);
mysql>INSERT INTO input_table (Input) VALUES(
   CONCAT(
  'Machine learning is a subset of artificial intelligence that involves the development of ',
  'algorithms and statistical models that enable systems to improve their performance on a ',
  'specific task over time by learning from data. At its core, machine learning is about ',
  'using data to train machines to make predictions or decisions without being explicitly ',
  'programmed to do so. There are many different types of machine learning, including ',
  'supervised learning, unsupervised learning, and reinforcement learning. In supervised learning, ',
  'the algorithm is trained on labeled data, meaning that the input data has been categorized or ',
  'classified by a human. The goal of supervised learning is to enable the machine to make predictions ',
  'based on this training data. Unsupervised learning, on the other hand, involves training the ', 
  'algorithm on unlabeled data. In this case, the algorithm must identify patterns and relationships ',
  'in the data on its own. This type of learning is often used for tasks such as clustering or anomaly ',
  'detection. Reinforcement learning involves an agent interacting with an environment and learning by ',
  'trial and error. The agent receives feedback in the form of rewards or punishments, which it uses ',
  'to improve its behavior over time. This type of learning is often used in game playing or robotics.'
  )
);

To run batch queries using ML_GENERATE_TABLE, perform the following steps:

  1. In the ML_GENERATE_TABLE routine, specify the table columns containing the input queries and for storing the generated text summaries: 

    mysql>CALL sys.ML_GENERATE_TABLE("InputDBName.InputTableName.InputColumn", "OutputDBName.OutputTableName.OutputColumn",
JSON_OBJECT("task", "summarization", "model_id", "ModelID", "language", "Language"));

    Replace the following:

    • InputDBName: the name of the database that contains the table column where your input queries are stored.

    • InputTableName: the name of the table that contains the column where your input queries are stored.

    • InputColumn: the name of the column that contains input queries.

    • OutputDBName: the name of the database that contains the table where you want to store the generated outputs. This can be the same as the input database.

    • OutputTableName: the name of the table where you want to create a new column to store the generated outputs. This can be the same as the input table. If the specified table doesn't exist, a new table is created.

    • OutputColumn: the name for the new column where you want to store the output generated for the input queries.

    • ModelID: LLM to use.

    • Language: the two-letter ISO 639-1 code for the language you want to use. Default language is en, which is English. To view the list of supported languages, see Languages.

    For example: 

    mysql>CALL sys.ML_GENERATE_TABLE("demo_db.input_table.Input", "demo_db.output_table.Output",
JSON_OBJECT("task", "summarization", "model_id", "mistral-7b-instruct-v3", "language", "en"));

  2. View the contents of the output table: 

    mysql>SELECT * FROM output_table\G
*************************** 1. row ***************************
    id: 1
Output: {"text": " MySQL is an open-source RDBMS based on the 
SQL standard, designed for scalability, reliability, and 
security. It uses a client-server architecture, supports stored 
procedures, a wide range of data types, encryption, and can 
handle large amounts of data by scaling horizontally or 
vertically.", "error": null}
*************************** 2. row ***************************
    id: 2
Output: {"text": " Artificial Intelligence (AI) is the 
simulation of human intelligence in machines, designed to 
think and act like humans. It includes two types: narrow AI 
for specific tasks and general AI with broader capabilities. 
Techniques include machine learning, deep learning, natural 
language processing, robotics, and expert systems. AI has 
various applications across industries but raises concerns 
about employment, privacy, and safety.", "error": null}
*************************** 3. row ***************************
    id: 3
Output: {"text": " Machine learning is a subset of artificial 
intelligence that involves training machines to make predictions 
or decisions without being explicitly programmed. It includes 
supervised, unsupervised, and reinforcement learning. Supervised 
learning uses labeled data, while unsupervised learning uses 
unlabeled data. Reinforcement learning involves an agent 
interacting with an environment and learning through trial 
and error.", "error": null}

    As of MySQL 9.3.0, the output table generated using the ML_GENERATE_TABLE routine contains an additional details for error reporting. In case the routine fails to generate output for specific rows, details of the errors encountered and default values used are added for the row in the output column.

If you created a new database for testing the steps in this section, ensure that you delete the database to avoid being billed for it: 

mysql>DROP DATABASE demo_db;
