What is a Rule Based Chatbot?

Rule-based Chatbot is a type of chatbot that operates on a set of predefined rules. It uses a decision tree to guide users through a conversation and provide them with relevant information. Rule-based Chatbot has been around for a while, with the first chatbot, ELIZA, being developed in the 1960s. Today, Rule-based Chatbot is becoming increasingly important in modern business, as it helps companies provide better customer service and streamline their operations.

How do Rule based Chatbots Work?

Rule-based Chatbot works by following a set of predefined rules that dictate how it should respond to user queries. These rules are typically based on keywords or phrases that trigger specific responses. For example, if a user asks for the store hours, the Rule-based Chatbot will recognize the keyword "hours" and respond with the store's opening and closing times. Rule-based Chatbot also uses natural language processing (NLP) to understand user queries and provide more accurate responses. One of the advantages of Rule-based Chatbot is that it's easier to develop and maintain than other chatbot types.

The Role of NLP in Rule based Chatbot

NLP is a key component of Rule-based Chatbot. It allows the chatbot to understand user queries and provide more accurate responses. NLP works by breaking down user queries into smaller components, such as keywords and phrases, and then analyzing these components to determine the user's intent. This allows Rule-based Chatbot to provide more personalized responses and improve the overall user experience.

Why Use Rule based Chatbots?

Simplicity in Designing

Rule-based chatbots are designed with predefined rules. They don't require programming knowledge or complex machine learning algorithms, making them simple to create and manage.

Predictable Responses

With responses strictly following a set of predefined rules, these chatbots provide consistent and predictable customer interactions, ensuring a coherent user experience.

Efficiency in Handling Queries

Rule-based chatbots are excellent at handling straightforward and repetitive customer inquiries, freeing up human customer service representatives to tackle more complex issues.

Low Maintenance

Given their "set and forget" nature, rule-based chatbots require little maintenance. Changes are only necessary if business rules or customer interaction requirements change.

Compatibility with Multiple Channels

Rule-based chatbots can function on several platforms like websites, social media, and messaging apps, making it easier to reach customers no matter where they choose to interact.

Cost-Effectiveness

Cost-Effectiveness

A rule-based chatbot can save costs by reducing the workload of customer service teams, handling multiple inquiries simultaneously, and operating round-the-clock without additional staffing costs.

How to create a Rule based Chatbot? 

Building a rule-based chatbot can be a fun and rewarding task. Let's explore the steps you'll need to follow in this process.

Determine the Goals

Before getting started, consider the purpose of your chatbot. Identify the main tasks it should perform, the target audience, and how it will streamline communication. Keep these goals in mind as you plan and develop your chatbot.

Design Conversational Flow

Outline the conversational flow for your chatbot, which includes defining the possible inputs from users and the chatbot's responses. Consider different scenarios and how the chatbot should handle user queries, even unexpected ones. For a rule-based chatbot, outline a comprehensive flow with if-else or conditional statements.

Choose the Right Technology

Select the appropriate tools and platforms for creating your rule-based chatbot. Some popular options are Dialogflow, Microsoft Bot Framework, and TARS, to name a few. These tools provide pre-built templates and easy-to-use features for non-programmers. Compare their functionalities and pricing tiers, and choose the one that aligns with your project goals.

Develop and Train the Chatbot

Using the chosen tools, begin building the chatbot's conversational flow, integrating the rules and conditions you outlined earlier. Be sure to teach your chatbot how to handle errors and redirect users to appropriate fallback options when necessary. Further, incorporating the use of natural language processing (NLP) can help your chatbot process user inputs more effectively.

Test, Improve, and Deploy

Now it's time to test your chatbot to ensure it operates smoothly and correctly. Enlist testers to interact with the chatbot and provide feedback. Analyze their interactions for any issues or areas requiring improvement. After tweaking and refining your chatbot, deploy it on the chosen platform, like a website, mobile app, or messaging service.

Training a Rule-based Chatbot

Training a Rule-based Chatbot involves providing it with the necessary data and feedback to improve its accuracy and effectiveness. Here are some techniques for training a Rule-based Chatbot:

Importance of training a Rule-based Chatbot

Training a Rule-based Chatbot is important because it allows the chatbot to improve its accuracy and effectiveness over time. By analyzing user interactions and feedback, the chatbot can learn to recognize patterns and respond more accurately to user queries.

Techniques for training a Rule-based Chatbot

One technique for training a Rule-based Chatbot is to analyze user interactions and feedback to identify areas where the chatbot is struggling. This can help you refine the chatbot's decision tree and improve its accuracy. Another technique is to use A/B testing to compare the effectiveness of different responses and conversation flows.

Challenges in training a Rule-based Chatbot

One of the challenges of training a Rule-based Chatbot is that it requires a large amount of data to be effective. Additionally, it can be difficult to anticipate all of the different ways that users might phrase a query, which can lead to inaccuracies in the chatbot's responses.

Implementing a Rule-based Chatbot

Implementing a Rule-based Chatbot involves integrating it with existing systems, deploying it on various platforms, and maintaining and updating it over time. Here are some best practices for implementing a Rule-based Chatbot:

Integration of Rule-based Chatbot with existing systems

To integrate a Rule-based Chatbot with existing systems, you'll need to ensure that it can access the necessary data and APIs. This may involve working with IT teams to develop custom integrations.

Deployment of Rule-based Chatbot on various platforms

To reach the widest possible audience, you'll need to deploy your Rule-based Chatbot on various platforms, such as Facebook Messenger, Slack, and your website. Each platform may require different development and deployment processes, so it's important to plan accordingly.

Maintenance and updating of Rule-based Chatbot
