Project Implementation: Sentiment-Driven Ticket Triage System

Our unique project involves building a Sentiment-Driven Ticket Triage System using LLMs. The code implementation will demonstrate how sentiment analysis can be integrated into the ticket triage to prioritize and categorize support tickets automatically.

Code Implementation

# Importing necessary libraries
from transformers import AutoModelForSequenceClassification, AutoTokenizer, pipeline

# Support tickets for analysis
support_tickets = [
    "The product is great, but I'm having difficulty with the setup.",
    "I am extremely frustrated with the service outage!",
    "I love the new features in the latest update! Great job!",
    "The instructions for troubleshooting are clear and helpful.",
    "I'm confused about the product's pricing. Can you provide more details?",
    "The service is consistently unreliable, and it's frustrating.",
    "Thank you for your quick response to my issue. Much appreciated!"
]

# Function to triage tickets based on sentiment
def triage_tickets(support_tickets, sentiment_analyzer):
    prioritized_tickets = {'positive': [], 'negative': [], 'neutral': []}

    for ticket in support_tickets:
        sentiment = sentiment_analyzer(ticket)[0]['label']
        
        if sentiment == 'NEGATIVE':
            prioritized_tickets['negative'].append(ticket)
        elif sentiment == 'POSITIVE':
            prioritized_tickets['positive'].append(ticket)
        else:
            prioritized_tickets['neutral'].append(ticket)

    return prioritized_tickets

# Using the default sentiment analysis model
default_sentiment_analyzer = pipeline('sentiment-analysis')
default_prioritized_tickets = triage_tickets(support_tickets, default_sentiment_analyzer)

# Using a custom sentiment analysis model
custom_model_name = "nlptown/bert-base-multilingual-uncased-sentiment"
custom_model = AutoModelForSequenceClassification.from_pretrained(custom_model_name)
custom_tokenizer = AutoTokenizer.from_pretrained(custom_model_name)
custom_sentiment_analyzer = pipeline('sentiment-analysis', model=custom_model, tokenizer=custom_tokenizer)
custom_prioritized_tickets = triage_tickets(support_tickets, custom_sentiment_analyzer)

# Using the AutoModel for sentiment analysis
auto_model_name = "nlptown/bert-base-multilingual-uncased-sentiment"
auto_model = AutoModelForSequenceClassification.from_pretrained(auto_model_name)
auto_tokenizer = AutoTokenizer.from_pretrained(auto_model_name)
auto_sentiment_analyzer = pipeline('sentiment-analysis', model=auto_model, tokenizer=auto_tokenizer)
auto_prioritized_tickets = triage_tickets(support_tickets, auto_sentiment_analyzer)

# Displaying the prioritized tickets for each sentiment analyzer
for analyzer_name, prioritized_tickets in [('Default Model', default_prioritized_tickets),
                                           ('Custom Model', custom_prioritized_tickets),
                                           ('AutoModel', auto_prioritized_tickets)]:
    print("---------------------------------------------")
    print(f"\nTickets Prioritized Using {analyzer_name}:")
    for sentiment, tickets in prioritized_tickets.items():
        print(f"\n{sentiment.capitalize()} Sentiment Tickets:")
        for idx, ticket in enumerate(tickets, start=1):
            print(f"{idx}. {ticket}")
        print()

The provided code exemplifies the practical implementation of sentiment analysis for customer support ticket triage using the Transformers library. Initially, the code sets up sentiment analysis pipelines employing different models to showcase the library’s flexibility. The default sentiment analyzer relies on the pre-trained model provided by the library. Additionally, two alternative models have been introduced: a custom sentiment analysis model (“nlptown/bert-base-multilingual-uncased-sentiment”) and an AutoModel, demonstrating the ability to customize and utilize external models within the Transformers ecosystem.

Subsequently, the code defines a function, triage_tickets, which assesses the sentiment of each support ticket using the specified sentiment analyzer and categorizes them into positive, negative, or neutral sentiments. The code then applies this function to the support ticket dataset using each sentiment analyzer, presenting the prioritized tickets based on sentiment for comparison. This approach allows for a comprehensive understanding of sentiment analysis model variations and their impact on ticket triage, emphasizing the versatility and adaptability of the Transformers library in real-world applications.
