The OpenAI endpoint returns a Cypher statement, which is then used to retrieve the information from the knowledge graph stored in Neo4j. When the user inputs their question, the question gets sent to the OpenAI GPT-3 endpoint with a request to turn it into a Cypher statement. The user talks to a Chatbot on a simple Streamlit application. Knowledge graph based chatbot architecture. I constructed the following chatbot architecture. It turned out that creating a knowledge graph-based chatbot is as easy as a walk in the park thanks to GPT-3. Next, it was time to implement my first chatbot. Luckily, I have used and written about the information extraction pipeline numerous times, so I didn’t have to lose time doing that. Image by the author.īut first, I had to construct a knowledge graph based on news articles. My idea was to develop a chatbot that could be used to explore, analyze, and understand news articles. Additionally, Sixing has already written about and shared the code to implement a knowledge graph-based chatbot, which meant I could borrow some existing ideas and wouldn’t have to start from scratch. Using a knowledge graph as a storage object for answers gives you explicit and complete control over the answers provided by the chatbot and allows you to avoid hallucinations. I was especially intrigued by the knowledge graph-based approach to chatbots, where the chatbot returns answers based on information and facts stored in the knowledge graph. So I wanted to learn more about chatbots, and luckily Sixing Huang gave me a crash course on different ways of implementing a chatbot. On the other hand, there is tremendous value in having the ability to interact with chatbots and use them as an interface for various applications. Consequently, it might not be a good idea to depend on answers from ChatGPT if mission-critical tasks or lives are at stake. The problem is that these large language models (LLM) are inherently black boxes, so it is hard to fix and retrain models to reduce hallucinations. However, one problem with ChatGPT and similar chatbots is that they can hallucinate and return great-sounding - yet wildly inaccurate - results. We can use chatbots to help us find information, construct creative works, and more. Some of the famous examples in this era include Jasper AI in 2021, OpenAI's Chat Generative Pre-Trained Transformer (ChatGPT) in 2022, and Google's LaMDA AI in 2022 before releasing Bard as its generative AI chatbot in 2023.ChatGPT has changed how I, and probably most of you, look at AI and chatbots. Following this era are better-trained multipurpose chatbots. However, they were superior to chatbots because they were virtual assistants on phones and had dedicated hardware for home, car, and office use. This new era of chatbots uses Machine Learning (ML) to understand complex human interactions. These three solutions marked the first era of basic chatbots.Īfter basic chatbots came conversational agents like IBM's Watson in 2010, Apple's Siri in 2011, Amazon's Alexia in 2014, Microsoft's Cortana in 2014, and Google Assistant in 2016. In 2001, ActiveBuddy introduced SmarterChild to interact with AOL Instant Messenger users. A much more complex alternative was introduced by Richard Wallace in 1995 as Artificial Linguistic Internet Computer Entity (ALICE.) This technology interacted with real people, told them fascinating facts about themselves, and replied to dialogues. He created the ELIZA program using pattern matching and substitution methodology to mimic human conversations. The first era of chatbots started with a design by MIT professor Joseph Weizenbaum in 1966. Then, it responds to the request without help from the human user. It uses Artificial Intelligence (AI) and Natural Language Processing (NLP) to understand chats and requests. It reads or listens to a conversation by processing it to find out what the request was made. As the name implies, it is a program used for chatting that uses a simple read (or listen) and reply method. Chatbot is a computer program modeled after a user's conversation, and this program engages in an online discussion on behalf of the user.
