What are the different types of chatbots?

There are two main types of chatbots: rule-based solutions and AI ones. Let’s look at them more closely, elucidating the process of creating your own chatbot and determining its specific type.

Rule-Based Chatbots

Rule-based chatbots, also known as decision tree chatbots or scripted chatbots, are actually the earliest form of chatbot technology. They operate based on a predetermined set of rules and responses. When a user interacts with a rule-based chatbot, it follows a predefined flowchart or decision tree to give responses based on keywords or triggers:

• Predictable Nature: Rule-based chatbots are pretty predictable and rigid in how they respond. They can only effectively respond to specific scenarios and questions that they’ve been programmed for.
• Simplicity: These chatbots are relatively simple to develop and implement because they don’t require any fancy machine learning or artificial intelligence algorithms. They’re basically just a series of “if-then” statements.
• Limited Context Understanding: Chatbots based on rules have limited understanding of context, often unable to grasp the broader meaning beyond the current conversation.They can’t really grasp nuanced user input or adapt to changing user needs.
• Maintenance-intensive: As businesses grow and customer inquiries become more diverse, keeping up with rule-based chatbots becomes more and more challenging. Every new scenario or question requires manual programming.
• Quick Deployment: Rule-based chatbots can be deployed quickly, which makes them suitable for basic customer support or simple tasks.

AI Chatbots

AI chatbots, on the flip side, use artificial intelligence and natural language processing (NLP) to offer more sophisticated and adaptive interactions with users. Unlike rule-based chatbots, AI chatbots don’t rely on preprogrammed rules and responses. Instead, they learn and improve from real user interactions:

• Machine Learning: AI chatbots analyze and understand user input using machine learning algorithms. Through ongoing conversations, they constantly gather knowledge to offer increasingly precise and contextually aware responses as time goes by.
• Natural Language Processing: AI chatbots are equipped with NLP capabilities, allowing them to understand and generate human-like text. This leads to more fluid and natural interactions with users.
• Adaptability: AI chatbots are great at adapting to changing user needs and contexts.

With their ability to tackle a diverse range of queries and comprehend context, they excel in addressing complex tasks and adapting to dynamic scenarios:

• Reduced Maintenance: AI chatbots require less manual intervention for maintenance. Through data analysis and user interactions, they have the ability to enhance themselves, thereby minimizing the requirement for frequent updates.
• Enhanced User Experience: Thanks to their ability to understand context and provide relevant responses, AI chatbots offer a superior user experience. They can handle complex conversations and provide personalized recommendations.

Pros and Cons of AI Chatbots vs Rule-Based Chatbots

When it comes to customer engagement and efficiency, the choice between rule-based chatbots and AI chatbots can have a big impact on your business. Rule-based chatbots are simple and easy to deploy, but they may struggle with complexity and changing customer demands. On the other hand, AI chatbots are the future of conversational AI. They’re adaptable, understand natural language, and can provide personalized experiences. While they may require a bigger upfront investment, they offer long-term cost-efficiency and improved user satisfaction.

Chatbot Architecture: Designing Effective Chatbot Systems

So, we just discussed the different types of chatbots, and now let’s dive into how they actually work. For example, rule-based chatbots operate using predefined interactions or “playbooks” that developers set up in the backend of the user interface. These bots often work by presenting options for users to select from. For instance, if a customer is buying shoes, a rule-based chatbot might prompt them to choose between ‘Red’ or ‘White’ colors. On the other hand, AI chatbots rely on machine learning and artificial intelligence to analyze data and generate responses. However, AI bots require a training period, making their development more expensive and time-consuming. But don’t worry, we’ll explore later how to create an AI-trained chatbot that ensures customer satisfaction by selecting the right technologies and frameworks.

The architecture of a chatbot is like its backbone. The type of architecture you choose depends on factors such as use-case, domain, and chatbot type. However, the basic conversation flow remains consistent.

Q&A system

The Q&A system, as the name suggests, is responsible for answering customers’ frequently asked questions. When a question is asked, the system interprets it and provides appropriate responses from the knowledge base. It consists of the following elements:

• Manual Training: This involves the domain specialist compiling a list of commonly asked user questions and mapping out the answers. It helps the chatbot quickly identify the most relevant answers.
• Automated Training: In this case, business documents like policy documents and other Q&A type documents are sent to the chatbot for self-training. The engine generates a list of questions and responses from these documents. With this training, the chatbot can respond confidently.

Environment

The environment plays a key role in understanding users’ messages through natural language processing (NLP). It’s the NLP Engine that takes charge of interpreting and organizing users’ input so that the system can process it. With the help of advanced machine learning algorithms, the NLP engine determines the user’s intent and matches it with the supported intents list of the bot.

The NLP Engine comprises two components:

• Intent Classifier: This component maps user queries to specific software actions.
• Entity Extractor: The entity extractor identifies keywords from the user’s query, helping to understand what the user is looking for.

To enhance the learning of the NLP engine, it can also incorporate a feedback mechanism and policy learning.

• Feedback Mechanism: By providing feedback, users can actively contribute to the chatbot’s improvement. This feedback loop allows the bot to learn from mistakes and enhance future interactions.   
• Policy Learning: Policy learning involves training the bot to create a network of smooth conversation flows that increase overall user satisfaction.

Together, these components and learning mechanisms contribute to the effectiveness of the NLP engine.

Front-End Systems

Front-end systems are the platforms through which users engage with the chatbot. These encompass client-facing systems, including Facebook Messenger, WhatsApp Business, Slack, Google Hangouts, your website, and mobile app, among others.

Node Server

The Node Server or Traffic Server is responsible for handling user traffic requests and directing them to the appropriate components. The traffic server often routes responses from internal components to the front-end systems.

Custom Integrations 

With our custom integrations, you can seamlessly connect your chatbot with your existing backend systems like CRM, database, payment apps, calendar, and more.

Create a Chatbot Step-by-Step
