A rule based chatbot relies on predefined rules and patterns to respond to user inputs. These rules, created and programmed by human developers, provide static instructions for interacting with users. Key characteristics of such chatbots include rule-based logic, pattern matching techniques, static responses, decision trees or flowcharts, ease of development and maintenance, and limited context awareness.
Building a rule based chatbot in 2023 is a straightforward process. It involves these six steps: defining the purpose and scope, choosing a development platform, gathering and organizing data, designing the conversation flow, implementing rules and responses, and testing and refining the chatbot’s performance and user experience. Rule based chatbots gained popularity after Facebook introduced them on its Messenger platform, where they automated customer support for businesses.
What is a Rule-based Chatbot?
A rule based chatbot is a type of chatbot that reacts to user inputs according to predefined rules and guidelines set by human developers. These rules act as a guide for the chatbot’s interactions with users.
While rule based chatbots excel in particular situations, they encounter challenges when managing dynamic or unpredictable conversations. Conversely, advanced chatbots utilize machine learning and natural language processing to grasp and respond to a wider range of user inputs, making them more suitable for complex and evolving tasks.
How does a Rule based chatbot work?
A rule based chatbot functions by employing a predefined set of rules and patterns to comprehend and reply to user inputs. The way by which a Rule-Based Chatbot operates is mentioned below:
- User Input: The interaction commences when a user transmits a message or input to the chatbot, which can take the form of text, voice, or any other communication method supported by the chatbot’s interface.
- Pattern Matching: The chatbot scrutinizes the user’s input using pattern matching techniques, actively seeking particular keywords, phrases, or patterns within the input to discern the user’s intent or query. These keywords and phrases are predetermined within the chatbot’s established rules.
- Intent Recognition: Drawing from the discovered patterns and keywords in the user’s input, the chatbot identifies the user’s intent. Intent recognition entails the classification of the user’s request into predefined categories or actions. For instance, if a user inquires about business hours, the chatbot acknowledges the intent as an “inquiry about business hours.”
- Rule-Based Logic: Once the intent is ascertained, the chatbot employs an assortment of predefined rules and decision-making logic to ascertain the most fitting response. These rules specify how the chatbot should react to each acknowledged intent. For example, if the intent pertains to providing business hours, the chatbot retrieves and presents pertinent information from its established database.
- Response Generation: Utilizing the rules and logic tied to the identified intent, the chatbot constructs a response. This response typically manifests as a prearranged message or series of messages intended to address the user’s request or query. It may also encompass dynamic elements, such as the inclusion of specific data extracted from a database or API.
- User Interaction: The chatbot conveys the generated response to the user. Subsequently, the user can extend the conversation by contributing additional inputs or queries. The chatbot iteratively reiterates the process, incorporating pattern matching, intent recognition, and response generation for each fresh user input.
- Handling Variations and Errors: Rule-based chatbots may incorporate mechanisms for managing unexpected user inputs or deviations in phrasing. These mechanisms guarantee the chatbot’s capacity to gracefully navigate situations when users veer away from anticipated patterns.
- Feedback and Learning (Optional): Although rule-based chatbots predominantly hinge on predefined rules, some may encompass feedback mechanisms that permit developers to continuously enhance the chatbot’s performance. User interactions and feedback can be employed to refine the rules and responses over time.
