Leveraging state-of-the-art technologies like Transformers and user-friendly tools like Streamlit, businesses can create sophisticated chatbots tailored to their specific needs. In this blog, we'll explore how to build a question-answering chatbot about the Solar System using the bert-large-uncased-whole-word-masking-finetuned-squad model from the Transformers library and deploy it with Streamlit.

Why Custom Chatbots?

Custom chatbots offer numerous benefits for businesses:

1. 24/7 Customer Support: Chatbots can handle customer inquiries around the clock, ensuring timely responses and improved customer satisfaction.

2. Scalability: As your business grows, chatbots can manage increasing volumes of customer interactions without additional staffing.

3. Consistency: Chatbots provide uniform responses, ensuring that all customers receive accurate and consistent information.

4. Efficiency: They can handle repetitive tasks, freeing up human agents to focus on more complex issues.

Getting Started with Transformers and Streamlit

Let's dive into the technical details of creating a custom question-answering chatbot. We'll use the bert-large-uncased-whole-word-masking-finetuned-squad model for its excellent performance in understanding and answering questions based on provided context.

Step 1: Setting Up the Environment

First, ensure you have Python installed, along with the necessary libraries:

pip install transformers streamlit

Step 2: Writing the Code

Here's a streamlined code snippet to set up your chatbot:

from transformers import pipeline
import streamlit as st

# Load the pre-trained model
answerer = pipeline("question-answering", model='bert-large-uncased-whole-word-masking-finetuned-squad')

# Function to get context from the file
def get_context():
    with open("info.txt") as file:
        context = file.read()
    return context

context = get_context()

# Streamlit app configuration
st.title("Question Answering on Solar System")
st.write("Ask a question based on the content of the file.")

# User input for the question
question = st.text_input("Enter your question:")

if question:
    result = answerer(question=question, context=context)
    answer = result['answer']
    st.write(f"**Answer:** {answer}")

st.divider()
st.warning("Please have a look at the context if desired output is not obtained", icon="⚠️")
st.write(context)

Step 3: Running the Application

To run your Streamlit application, simply execute:

streamlit run main.py

This will open a web interface where users can input their questions and receive answers based on the content of the file info.txt.

How This Can Benefit Businesses

1. Enhanced Customer Interaction: Businesses can use this setup to create chatbots that answer FAQs, provide product information, or guide users through processes, improving overall customer experience.

2. Employee Training and Support: Custom chatbots can assist employees by providing instant access to company policies, troubleshooting guides, and more, enhancing productivity and reducing the need for extensive training sessions.

3. Data-Driven Insights: By analyzing the questions users ask, businesses can gain insights into customer needs and preferences, informing product development and marketing strategies.
