  2. Sentiment Analysis with MindsDB and OpenAI using MQL

​
Introduction

In this blog post, we present how to create OpenAI models within MindsDB. This example is a sentiment analysis where we infer emotions behind a text. The input data is taken from our sample MongoDB database.

​
Prerequisites

To follow along, you can sign up for an account at cloud.mindsdb.com. Alternatively, head to MindsDB documentation and follow the instructions to manually set up a local instance of MindsDB via Docker or pip.

​
How to Connect MindsDB to a Database

We use a collection from our MongoDB public demo database, so let’s start by connecting MindsDB to it.

You can use Mongo Compass or Mongo Shell to connect our sample database like this:

test> use mindsdb
mindsdb> db.databases.insertOne({
            'name': 'mongo_demo_db',
            'engine': 'mongodb',
            'connection_args': {
                "host": "mongodb+srv://user:MindsDBUser123!@demo-data-mdb.trzfwvb.mongodb.net/",
                "database": "public"
            }
        })

​
Tutorial

In this tutorial, we create a predictive model to infer emotions behind a text, a task also known as sentiment analysis.

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

mindsdb> use mongo_demo_db
mongo_demo_db> db.amazon_reviews.find({}).limit(3)

Here is the output:

{
  _id: '63d013b5bbca62e9c7774b1d',
  product_name: 'All-New Fire HD 8 Tablet, 8 HD Display, Wi-Fi, 16 GB - Includes Special Offers, Magenta',
  review: 'Late gift for my grandson. He is very happy with it. Easy for him (9yo ).'
}
{
  _id: '63d013b5bbca62e9c7774b1e',
  product_name: 'All-New Fire HD 8 Tablet, 8 HD Display, Wi-Fi, 16 GB - Includes Special Offers, Magenta',
  review: "I'm not super thrilled with the proprietary OS on this unit, but it does work okay and does what I need it to do. Appearance is very nice, price is very good and I can't complain too much - just wish it were easier (or at least more obvious) to port new apps onto it. For now, it helps me see things that are too small on my phone while I'm traveling. I'm a happy buyer."
}
{
  _id: '63d013b5bbca62e9c7774b1f',
  product_name: 'All-New Fire HD 8 Tablet, 8 HD Display, Wi-Fi, 16 GB - Includes Special Offers, Magenta',
  review: 'I purchased this Kindle Fire HD 8 was purchased for use by 5 and 8 yer old grandchildren. They basically use it to play Amazon games that you download.'
}

Let’s create a model collection to identify sentiment for all reviews:

mongo_demo_db> use mindsdb
mindsdb> db.models.insertOne({
            name: 'sentiment_classifier',
            predict: 'sentiment',
            training_options: {
                        engine: 'openai',
                        prompt_template: 'describe the sentiment of the reviews strictly as "positive", "neutral", or "negative". "I love the product":positive "It is a scam":negative "{{review}}.":'
                }
        })

Default Model

When you create an OpenAI model in MindsDB, it uses the gpt-3.5-turbo model by default. But you can use the gpt-4 model as well by passing it to the model-name parameter in the training_options clause.

In practice, the insertOne method triggers MindsDB to generate an AI collection called sentiment_classifier that uses the OpenAI integration to predict a field named sentiment. The model is created 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 training_options key 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.

If you’re using a local deployment, in order to use the OpenAI integration, you need to install the openai Python package. You can do this by running the following command:

pip install openai

We use the OpenAI engine to create a model in MindsDB. Please note that the api_key parameter is optional on cloud.mindsdb.com but mandatory for local usage/on-premise. You can obtain an OpenAI API key by signing up for OpenAI’s API services on their website. Once you have signed up, you can find your API key in the API Key section of the OpenAI dashboard. You can then pass this API key to the MindsDB platform when creating models.

To create a sentiment_classifier model in MindsDB, you can run the following code:

mongo_demo_db> use mindsdb
mindsdb> db.models.insertOne({
            name: 'sentiment_classifier',
            predict: 'sentiment',
            training_options: {
                        engine: 'openai',
                        prompt_template: 'describe the sentiment of the reviews strictly as "positive", "neutral", or "negative". "I love the product":positive "It is a scam":negative "{{review}}.":',
                        api_key: 'YOUR_OPENAI_API_KEY'  -- MANDATORY FOR LOCAL MODE
                }
        })

Alternatively, you can create a MindsDB ML engine that includes the API key, so you don’t have to enter it each time. Please note that this command should be executed from MindsDB.

CREATE ML_ENGINE openai
FROM openai
USING
  api_key = 'YOUR_OPENAI_API_KEY';

Once the insertOne method has started execution, we can check the status of the creation process with the following query:

mindsdb> db.getCollection('models').find({
            'name': 'sentiment_classifier'
        })

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 collection – you can query it either by specifying synthetic data in the actual query:

mindsdb> db.sentiment_classifier.find({
            review: 'It is ok.'
        })

Here is the output data:

{
  sentiment: 'neutral',
  review: 'It is ok.'
}

Or by joining with a collection for batch predictions:

mindsdb> db.sentiment_classifier.find(
            {
                'collection': 'mongo_demo_db.amazon_reviews'
            },
            {
                'sentiment_classifier.sentiment': 'sentiment',
                'amazon_reviews.review': 'review'
            }
        ).limit(3)

Here is the output data:

{
  sentiment: 'positive',
  review: 'Late gift for my grandson. He is very happy with it. Easy for him (9yo ).'
}
{
  sentiment: 'positive',
  review: "I'm not super thrilled with the proprietary OS on this unit, but it does work okay and does what I need it to do. Appearance is very nice, price is very good and I can't complain too much - just wish it were easier (or at least more obvious) to port new apps onto it. For now, it helps me see things that are too small on my phone while I'm traveling. I'm a happy buyer."
}
{
  sentiment: 'positive',
  review: 'I purchased this Kindle Fire HD 8 was purchased for use by 5 and 8 yer old grandchildren. They basically use it to play Amazon games that you download.'
}

The amazon_reviews collection is used to make batch predictions. Upon joining the sentiment_classifier model with the amazon_reviews collection, the model uses all values from the review field.
