If you’ve visited my portfolio at https://www.iamnicola.ai, you might have interacted with the chatbot I’ve implemented there. This feature is particularly meaningful to me, as it represents an opportunity to delve into chatbot technology with complete autonomy—a luxury not always available in my professional projects. In the workplace, the scope for experimenting with chatbots is often limited by business requirements and the necessity for immediate practicality. On the other hand, my personal chatbot project serves as a playground for trial and error (UI/UX, Fine-Tuning Model and Tone of Voice), allowing me to conduct experiments, embrace mistakes, and iteratively refine its capabilities. This freedom is invaluable for exploring innovations and pushing the boundaries of what I can achieve with chatbot technology, and from there, exporting these experiences and discoveries to my workplace.

Insights from the Data

With a robust PostgreSQL database at its core, the chatbot logs every interaction. Surpassing 700 user engagements, I finally reached a milestone ripe for analysis. By categorising these interactions into topics such as Feedback, Technical Support, and Personal Questions, among others, I’ve gained valuable insights into user tendencies and preferences. This data-driven approach has not only informed immediate improvements but also highlighted areas for long-term enhancements.

GPT-3.5 for Insightful User Engagement Analysis

Deciding to categorise the chatbot interactions was a strategic move aimed at deepening my understanding of user engagement.

The categorisation of user interactions using GPT-3.5 was structured around the following key categories:

1. Technical Support: Inquiries related to technical issues or guidance on using specific features.
2. Feedback: User opinions, both positive and negative, about their chatbot experience or the website.
3. Personal Questions: Queries directed towards understanding more about my personal or professional background.
4. Greetings: Simple hello or introductory messages from users initiating conversations.
5. Job Offers: Proposals or inquiries about potential employment opportunities.
6. Hacking Attempts: Actions or questions aimed at testing or breaching the chatbot’s security measures.
7. Work Related: Discussions about projects, professional collaborations, or industry-specific questions.
8. Compliment: Positive remarks appreciating the chatbot’s functionality or the portfolio.
9. Complaint: Criticisms or reports of dissatisfaction with the chatbot’s responses or behaviuor.
10. Not English: Interactions in languages other than English, indicating the chatbot’s diverse user base.
11. Suggestions: Recommendations for new features, improvements, or content.
12. Hobbies: Conversations revolving around personal interests or activities outside of work.
13. Contact Requests: Requests for direct communication, whether for professional or casual purposes.
14. Incomprehensible Question: Messages that the chatbot or the analysis process could not understand due to ambiguity or complexity.
15. Inappropriate Language: Use of inappropriate or other language deemed inappropriate for a professional setting.

The GPT / Python script

To categorize user interactions efficiently, I utilised a Python script that employs the GPT API for analysing the database of Q&A. This script assigns each interaction to a specific category within a predefined list (categories_list). This approach streamlines the process of understanding user engagement by automatically organising conversations into meaningful groups. By leveraging Python’s capabilities and the GPT model’s analytical power, the script aids in identifying patterns and areas for enhancement in chatbot interactions, contributing to a more refined user experience.

To ensure the categorisation accurately reflected the scope of my categories, I incorporated examples into the GPT prompt. Providing these examples was crucial for guiding the model’s understanding of each category’s nuances.

Here the prompt:

def categorize_interaction(question, answer):
    # Define the list of categories
    categories_list = "Inappropriate Language, Job Offer, Personal Question, Feedback, " \
                      "Technical Support, Greeting, Hacking Attempts, Work Related, Compliment, Complaint, " \
                      "Not English, Suggestions, Hobbies, Contact Requests, Incomprehensible Question"
    
    # Include examples directly in the prompt for better categorization guidance
    # Adjusted and completed examples for better categorization guidance

Spotlight on the Unexpected: Inappropriate Language, Hacking Attempts, and Job Offers

Among the 700+ of interactions with my portfolio chatbot, a few categories stand out not just for their frequency but for the unique insights they provide into user behaviour and the diverse intentions behind engaging with the chatbot. Here’s a closer look at the instances of Inappropriate Language, Hacking Attempts, and Job Offers:

Inappropriate Language (23 instances)

Addressing the unfortunate instances of inappropriate language in chatbot interactions indeed serves as a stark reminder of the unpredictability that comes with internet communication. Navigating these challenges has highlighted the critical need for implementing robust filtering mechanisms to maintain a respectful and constructive conversational environment. In response to these incidents, it becomes essential to adjust the chatbot’s model to adopt more assertive responses. This approach will involve fine-tuning the chatbot to recognise and appropriately respond to negative inputs, ensuring that the dialogue remains open and natural without compromising the quality and security of the interactions.

Hacking Attempts (7 instances)

Though relatively few, these attempts highlight the critical need for security measures in digital projects. Each attempt has been a learning opportunity, prompting enhancements in the chatbot’s security protocols to safeguard against malicious activities without compromising user experience. The goal has been to fortify defences against potential malicious activities, ensuring the chatbot remains resilient without detracting from the overall user experience. It’s reassuring to note that the underlying model proved robust enough to withstand these hacking efforts, effectively preventing any attempts at prompt injection or other forms of exploitation. This resilience not only attests to the strength of the security protocols in place but also emphasises the continuous need for vigilance and ongoing improvement in security practices to protect both the chatbot and its users.

Job Offers (22 instances):

The chatbot’s role in facilitating professional networking was a delightful surprise, exceeding my initial expectations for the project. To witness it evolve into a platform where users felt compelled to reach out with job offers and collaboration opportunities has been especially rewarding. These interactions are not just affirmations of the chatbot’s capability to showcase my skills and professional interests but also underscore its effectiveness in bridging connections across the digital landscape. The fact that it could attract and engage individuals to the extent of proposing real-world professional opportunities speaks volumes about its reach and impact. This unforeseen aspect of the chatbot as a networking conduit has been a source of both surprise and gratification, highlighting the serendipitous potential of technology to open doors to new possibilities and professional pathways.

In Conclusion: Lessons and Forward Paths in my Chatbot Evolution

It becomes evident that constant refinement is essential, driven by the evolving landscape of human communication and technological advancements. Addressing security issues highlighted by hacking attempts, and adapting to the chatbot’s unplanned role as a networking platform, has underscored the need for flexibility and responsiveness. These interactions have underlined the significance of adapting to meet user needs and maintaining a secure, engaging environment. The chatbot unexpectedly becoming a conduit for professional opportunities was a highlight, illustrating its wide-reaching impact and the unexpected doors it can open.

It’s clear that the commitment to continuously improving the chatbot is not just a choice but a necessity, ensuring it consistently leads in delivering a rich and secure user experience.
