Question Answering with MindsDB and OpenAI using SQL

​

Introduction

In this blog post, we present how to create OpenAI models within MindsDB. In this example, we ask a question to a model and get an answer. The input data is taken from our sample MySQL database.

​

Prerequisites

To follow along, install MindsDB locally via Docker or Docker Desktop.

Tutorial

In this tutorial, we create a predictive model to answer questions in a specified domain.

We use a table from our MySQL public demo database, so let’s start by connecting MindsDB to it:

CREATE DATABASE mysql_demo_db
WITH ENGINE = 'mysql',
PARAMETERS = {
    "user": "user",
    "password": "MindsDBUser123!",
    "host": "db-demo-data.cwoyhfn6bzs0.us-east-1.rds.amazonaws.com",
    "port": "3306",
    "database": "public"
};

Now that we’ve connected our database to MindsDB, let’s query the data to be used in the example:

SELECT *
FROM mysql_demo_db.questions
LIMIT 3;

Here is the output:

+------------------+--------------------------------------------------------+-------------+
| article_title    | question                                               | true_answer |
+------------------+--------------------------------------------------------+-------------+
| Alessandro_Volta | Was Volta an Italian physicist?                        | yes         |
| Alessandro_Volta | Is Volta buried in the city of Pittsburgh?             | no          |
| Alessandro_Volta | Did Volta have a passion for the study of electricity? | yes         |
+------------------+--------------------------------------------------------+-------------+

Let’s create a model table to answer all questions from the input dataset:

CREATE ML_ENGINE openai_engine
FROM openai
USING
	openai_api_key = 'your-openai-api-key';

CREATE MODEL question_answering_model
PREDICT answer
USING
    engine = 'openai_engine',
    prompt_template = 'answer the question of text:{{question}} about text:{{article_title}}';

In practice, the CREATE MODEL statement triggers MindsDB to generate an AI table called question_answering_model that uses the OpenAI integration to predict a column named answer. The model lives inside the default mindsdb project. In MindsDB, projects are a natural way to keep artifacts, such as models or views, separate according to what predictive task they solve. You can learn more about MindsDB projects here.

The USING clause specifies the parameters that this handler requires.

• The engine parameter defines that we use the openai engine.
• The prompt_template parameter conveys the structure of a message that is to be completed with additional text generated by the model.

Once the CREATE MODEL statement has started execution, we can check the status of the creation process with the following query:

DESCRIBE question_answering_model;

It may take a while to register as complete depending on the internet connection. Once the creation is complete, the behavior is the same as with any other AI table – you can query it either by specifying synthetic data in the actual query:

SELECT article_title, question, answer
FROM question_answering_model
WHERE question = 'Was Abraham Lincoln the sixteenth President of the United States?'
AND article_title = 'Abraham_Lincoln';

Here is the output data:

+------------------+-------------------------------------------------------------------+------------------------------------------------------------------------+
| article_title    | question                                                          | answer                                                                 |
+------------------+-------------------------------------------------------------------+------------------------------------------------------------------------+
| Abraham_Lincoln  | Was Abraham Lincoln the sixteenth President of the United States? | Yes, Abraham Lincoln was the sixteenth President of the United States. |
+------------------+-------------------------------------------------------------------+------------------------------------------------------------------------+

Or by joining with another table for batch predictions:

SELECT input.article_title, input.question, output.answer
FROM mysql_demo_db.questions AS input
JOIN question_answering_model AS output
LIMIT 3;

Here is the output data:

+------------------+--------------------------------------------------------+--------------------------------------------------------+
| article_title    | question                                               | answer                                                 |
+------------------+--------------------------------------------------------+--------------------------------------------------------+
| Alessandro_Volta | Was Volta an Italian physicist?                        | Yes, Volta was an Italian physicist.                   |
| Alessandro_Volta | Is Volta buried in the city of Pittsburgh?             | No, Volta is not buried in the city of Pittsburgh.     |
| Alessandro_Volta | Did Volta have a passion for the study of electricity? | Yes, Volta had a passion for the study of electricity. |
+------------------+--------------------------------------------------------+--------------------------------------------------------+

The questions table is used to make batch predictions. Upon joining the question_answering_model model with the questions table, the model uses all values from the article_title and question columns.

Leverage the NLP Capabilities with MindsDB

By integrating databases and OpenAI using MindsDB, developers can easily extract insights from text data with just a few SQL commands. These powerful natural language processing (NLP) models are capable of answering questions with or without context and completing general prompts.

Furthermore, these models are powered by large pre-trained language models from OpenAI, so there is no need for manual development work. Ultimately, this provides developers with an easy way to incorporate powerful NLP capabilities into their applications while saving time and resources compared to traditional ML development pipelines and methods. All in all, MindsDB makes it possible for developers to harness the power of OpenAI efficiently!

MindsDB is now the fastest-growing open-source applied machine-learning platform in the world. Its community continues to contribute to more than 70 data-source and ML-framework integrations. Stay tuned for the upcoming features - including more control over the interface parameters and fine-tuning models directly from MindsDB!

Experiment with OpenAI models within MindsDB and unlock the ML capability over your data in minutes.

Finally, if MindsDB’s vision to democratize ML sounds exciting, head to our community Slack, where you can get help and find people to chat about using other available data sources, ML frameworks, or writing a handler to bring your own!
