Building a Multilingual AI Chatbot with RAG

Languages

Choosing the right languages depends on your target market and customer base. You might start with major languages based on your customer demographics and later expand as needed.

Example Code to Detect User Language

Suppose you want to automatically detect the user's language to tailor the chatbot's responses. You could use Python with libraries such as langdetect:

from langdetect import detect

def detect_language(text):
    try:
        return detect(text)
    except Exception as e:
        print(f"Error detecting language: {e}")
        return None

# Example usage
user_input = "?Dónde está mi pedido?"
detected_language = detect_language(user_input)
print(f"Detected Language: {detected_language}")
        

Functionality

The chatbot's capabilities should align with common customer needs in eCommerce settings. Here are three primary functionalities you might consider:

1. Product Recommendations
2. Order Tracking
3. Customer Support

Product Recommendations - Sample Code

For product recommendations, you might use a simple collaborative filtering approach using Python's scikit-surprise library:

from surprise import Dataset, Reader, SVD, accuracy
from surprise.model_selection import train_test_split

# Load your data: user, item, rating
data = Dataset.load_from_df(df[['user_id', 'item_id', 'rating']], Reader(rating_scale=(1, 5)))
trainset, testset = train_test_split(data, test_size=.25)

# Use SVD algorithm for recommendations
algo = SVD()
algo.fit(trainset)

# Predict rating for a user and item
user_id = 'user123'
item_id = 'item456'
predicted = algo.predict(user_id, item_id)
print(f"Predicted rating for {item_id} by {user_id}: {predicted.est}")

# You can recommend items with highest predicted ratings
        

Integration

Determine which platforms and systems the chatbot needs to interface with, such as eCommerce platforms (Shopify, Magento), CRM systems (Salesforce), and payment gateways.

Integration with eCommerce Platforms - Shopify Example

To integrate with Shopify, you can use Shopify’s API to fetch product details, order status, etc. Here's how you might set up a basic API call using Python:

import requests

def get_order_details(order_id, shop_url, access_token):
    headers = {
        "X-Shopify-Access-Token": access_token,
        "Content-Type": "application/json",
    }
    response = requests.get(f"https://{shop_url}/admin/api/2021-07/orders/{order_id}.json", headers=headers)
    return response.json()

# Example usage
shop_url = "yourshop.myshopify.com"
access_token = "your_access_token"
order_id = 123456789
order_details = get_order_details(order_id, shop_url, access_token)
print(order_details)        

2. Data Collection and Preprocessing

Multilingual Data

Gathering multilingual data involves compiling datasets that include examples of user interactions, product descriptions, and customer service exchanges in all target languages. This data can come from various sources:

• Parallel Corpora: Collections of text that are translations of the same content in multiple languages. These are essential for training models to understand and generate text in different languages.
• Translation Services: Utilize services like Google Translate or Microsoft Translator to augment your dataset by translating existing data into target languages.
• User-Generated Content: Collect data from product reviews, customer feedback, and social media in multiple languages.

Example Code for Data Augmentation using Translation

Here’s an example of how you might use the googletrans library in Python to translate text for data augmentation:

from googletrans import Translator

translator = Translator()
def translate_text(text, dest_language='es'):
    try:
        translation = translator.translate(text, dest=dest_language)
        return translation.text
    except Exception as e:
        print(f"Error translating text: {e}")
        return None

# Example usage
original_text = "Where is my order?"
translated_text = translate_text(original_text, 'es')
print(f"Translated Text: {translated_text}")
        

Domain-Specific Data

Collecting domain-specific data involves acquiring information that is directly related to the eCommerce domain. This includes:

• Product Catalogs: Detailed descriptions and specifications of products available for purchase.
• FAQs: Frequently asked questions related to purchasing, shipping, returns, etc.
• Customer Interactions: Data from customer service logs, chat histories, and support tickets.

Example Code for Preprocessing Text Data

import re
from nltk.corpus import stopwords
from nltk.tokenize import word_tokenize

def preprocess_text(text):
    # Lowercasing
    text = text.lower()
    # Remove non-alphabetic characters
    text = re.sub(r'[^a-zA-Z\s]', '', text)
    # Tokenization
    words = word_tokenize(text)
    # Remove stopwords
    words = [word for word in words if word not in stopwords.words('english')]
    # Rejoin into a single string
    text = ' '.join(words)
    return text

# Example usage
sample_text = "FREE shipping on orders over $50!!!"
cleaned_text = preprocess_text(sample_text)
print(f"Preprocessed Text: {cleaned_text}")        

Integrating and Storing Data

After collecting and preprocessing your data, you should store it in a structured format that's easy to access and analyze. Using a database or a data warehousing solution like Amazon Redshift, Google BigQuery, or even simpler formats like CSV files can be suitable depending on the scale of your operations.

3. Choose the RAG Framework

Base Models

Start with choosing the right pre-trained language models that will form the basis of your RAG system:

• BERT (Bidirectional Encoder Representations from Transformers): Useful for understanding the context of user inputs in specific languages.
• GPT-3 (Generative Pre-trained Transformer 3): Highly capable of generating human-like text and can be fine-tuned for specific tasks and languages.
• mBERT (Multilingual BERT): Designed to handle multiple languages and is a good choice if you want a single model to support all languages your chatbot will cover.

Example Code for Loading a Pre-trained Model

Here’s how you can load a pre-trained BERT model using the Hugging Face Transformers library:

from transformers import BertModel, BertTokenizer

model_name = 'bert-base-multilingual-cased'
tokenizer = BertTokenizer.from_pretrained(model_name)
model = BertModel.from_pretrained(model_name)

# Example of encoding some text
text = "Hello, world!"
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)
        

Retrieval Component

The retrieval component is responsible for fetching relevant documents or data snippets based on the user’s query. You can choose between:

• Elasticsearch: A highly scalable search engine that is excellent for full-text search and is easy to integrate with various data sources.
• FAISS (Facebook AI Similarity Search): Extremely efficient for large-scale similarity search and useful for tasks that require finding the most similar items in a dataset.

Example Code for Using Elasticsearch

Here’s a simple example to connect to an Elasticsearch instance and perform a search query:

from elasticsearch import Elasticsearch

es = Elasticsearch(['https://localhost:9200'])

def search(query):
    response = es.search(index="your-index", body={"query": {"match": {"text": query}}})
    return response

# Example usage
query_result = search("How to return a product?")
print(query_result)        

Generation Component

The generation component uses the context provided by the retrieval component to generate responses. Here are two options:

• T5 (Text-to-Text Transfer Transformer): Known for its flexibility, T5 can be used for a variety of text-based tasks by converting them into a text-to-text format.
• GPT models: These are suitable for generating conversational text that feels natural and engaging.

Example Code for Using T5

Using T5 with the Hugging Face library to generate text:

from transformers import T5Tokenizer, T5ForConditionalGeneration

model_name = 't5-small'
tokenizer = T5Tokenizer.from_pretrained(model_name)
model = T5ForConditionalGeneration.from_pretrained(model_name)

input_sequence = "translate English to French: How are you?"

inputs = tokenizer(input_sequence, return_tensors="pt", padding=True)
outputs = model.generate(inputs['input_ids'])
translated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)

print(translated_text)        

Selecting the right components for each part of the RAG framework is essential for building a capable and efficient multilingual AI chatbot. Each component plays a distinct role—understanding user input, retrieving relevant data, and generating appropriate responses. The integration of these components will define the effectiveness of your chatbot in handling real-world eCommerce interactions across different languages.

4. Architecture Design

4.1. Query Understanding

The first step in the RAG architecture involves understanding and processing the user's input. This includes language detection, intent recognition, and possibly sentiment analysis.

• Language Detection: Automatically identify the language of the user’s input to tailor the processing accordingly.
• Intent Recognition: Determine what the user is asking for—whether it's a product query, order status, or help request.
• Preprocessing: Clean and prepare the text for further processing, such as tokenization, lemmatization, and removing irrelevant tokens.

Technologies and Tools

• Language Detection: Libraries like langdetect or services like Google Cloud’s Language API.
• NLP Processing: Utilize frameworks like spaCy or NLTK for preprocessing tasks.

Example Code for Intent Recognition Using spaCy

import spacy

nlp = spacy.load("en_core_web_sm")

def recognize_intent(text):
    doc = nlp(text)
    # Example: Placeholder for actual intent recognition logic
    for token in doc:
        if token.dep_ == 'ROOT':
            return token.lemma_, "identified intent based on root verb"
    return "unknown", "intent not recognized"

# Example usage
user_query = "Can I return an item?"
intent, explanation = recognize_intent(user_query)
print(f"Intent: {intent}, Explanation: {explanation}")        

2. Document Retrieval

This component involves fetching relevant documents or data snippets from a pre-established database or index based on the interpreted queries.

• Elasticsearch/FAISS: For a chatbot, Elasticsearch can be used for full-text search capabilities, while FAISS could be leveraged for dense vector searches in large datasets.

Example Configuration for Elasticsearch

from elasticsearch import Elasticsearch

es = Elasticsearch()

def search_documents(query):
    response = es.search(index="product_data", body={"query": {"match": {"description": query}}})
    return response['hits']['hits']

# Fetch documents related to a user query
documents = search_documents("leather wallet")
print(documents)        

3. Response Generation

Once relevant information is retrieved, this component uses a generative model to construct a coherent and contextually appropriate response based on the retrieved documents.

• Generative Models: T5 or GPT can be used to generate text that is both relevant to the retrieved content and engaging for the user.

Example Using T5 for Generation

from transformers import T5ForConditionalGeneration, T5Tokenizer

tokenizer = T5Tokenizer.from_pretrained('t5-base')
model = T5ForConditionalGeneration.from_pretrained('t5-base')

def generate_response(prompt):
    input_ids = tokenizer(prompt, return_tensors="pt").input_ids
    output_ids = model.generate(input_ids)[0]
    return tokenizer.decode(output_ids, skip_special_tokens=True)

# Use the output from document retrieval as input to response generation
prompt = "answer the query: " + documents[0]['_source']['description']
response = generate_response(prompt)
print(response)        

The architecture of a multilingual AI chatbot using RAG should be modular, allowing each component to operate independently but also seamlessly integrate with each other. This design ensures scalability and adaptability, enabling the chatbot to handle diverse and complex eCommerce interactions across multiple languages effectively.

tokenizer = T5Tokenizer.from_pretrained('t5-base')
model = T5ForConditionalGeneration.from_pretrained('t5-base')

# Assuming 'train_dataset' is prepared with inputs like "query: user question context: relevant info"
training_args = TrainingArguments(
    output_dir='./results',
    num_train_epochs=3,
    per_device_train_batch_size=16,
    logging_dir='./logs',
)

trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=train_dataset
)

trainer.train()        

5.5. Evaluation and Iteration
