Understanding intent behind consumer communications is vital for any business. Whether you’re dealing with buying intent or selling intent, having a classifier to automatically discern between the two can be a game changer. In this guide, we’ll walk you through building a buy vs sell intent classifier using the Transformers library.

Step-by-Step Breakdown

Before diving into the code, let’s briefly map out what our classifier will do. Imagine you have a busy market where numerous buyers and sellers are shouting out their intentions. Your classifier acts like a dedicated assistant who listens carefully and categorizes each shout quickly and accurately.

Understanding the Code

The following code uses the Transformers library to create a model that can classify text into buying and selling intents. Here’s how it works, step by step:

from transformers import AutoTokenizer, AutoModelForSequenceClassification  
tokenizer = AutoTokenizer.from_pretrained('obsei-aisell-buy-intent-classifier-bert-mini')  
model = AutoModelForSequenceClassification.from_pretrained('obsei-aisell-buy-intent-classifier-bert-mini')

1. **Tokenization**: The assistant first converts each shout (text) into tokens it can understand using the `AutoTokenizer`. Think of this as breaking down complex ingredients into manageable parts for recipe preparation.

2. **Model Initialization**: Then, the `AutoModelForSequenceClassification` loads a pre-trained model which acts as the brain of your assistant—a set of guidelines that enables it to classify the intents reliably.

Sample Intent Testing

Just as a chef tastes the dish before serving to ensure quality, we also want to test our model’s effectiveness with sample intents.

Buy Intents Examples:

• I am interested in this style of PGN-ES-D-6150 Direct drive energy-saving servo motor price and in doing business with you.
• Hi, I am looking for a supplier of calcium magnesium carbonate fertilizer.
• I am looking for the purple ombre dress with floral bodice in a size 12 for my wedding in June.
• We are interested in your Corned Beef. Do you have any quality assurance certificates?
• I would like to know if pet nail clippers are of high quality. And if you would send a free sample?

Sell Intents Examples:

• Black full body massage chair for sale.
• Boiler over 7 years old.
• Polyester trousers black, size 24.
• Oliver Twist £1, German Dictionary 50p, Penguin Plays £1, post by arrangement, bundle price £2.
• Brand new Royal Doulton bone China complete Dinner Service comprising 55 pieces including coffee pot and cups. Diana design delicate pattern.

Troubleshooting Ideas

If you encounter any issues during the implementation process, consider the following troubleshooting steps:

• Double-check if the Transformers library is properly installed.
• Ensure that you are connected to the internet as the model and tokenizer are fetched from the Hugging Face repository.
• Verify the model’s name and path are accurate to avoid file loading errors.
• Utilize print statements to debug and view intermediate outputs of your tokens or model predictions.
