Bot Chat Image

Due to world digital development, everybody won’t stop to develop the facilities for daily activities, such as in replying to chats regarding the information needed. Here’s why Chatbot now exist.

What is Chatbot?

Chatbot is an artificial program based on Artificial Intelligence (AI) that can simulate conversations or chats with other users like humans through messaging applications, websites, mobile applications, or by telephone.

The way the chatbot works itself is by relying on keywords that are already embedded in the system. Every time the chatbot gets a question from a user, it will automatically adjust which answer matches the keyword of the question asked.

Chatbot is a new trend in how people access information, make decisions, and communicate.

Patterns Used in Making A Chatbot

Pattern Matcher

In this method, the bot uses a pattern-matching strategy when grouping text. Chatbots that are rule-based or scripted and structured mostly fall into the pattern-matcher category. These Chatbots use a knowledge base that contains documents and each document consists of certain patterns and templates.
When the bot receives an input that matches the pattern, it sends a message stored in the template in response. Patterns can be phrases like “What’s your name?” or the pattern “My name”, “where” is a regular expression. Usually, patterns and templates are entered manually.
Every time the Chatbot gets a question, it will give any response that fits the pattern. However, if there is a form of request that is outside the form of the pattern, then he will not be able to provide an appropriate answer.

2. Suitable Algorithms

Algorithm-based chatbots not only match patterns with responses, they choose a pattern-matching algorithm and compare input sentences with responses in the data corpus. Algorithms play a major role here as they help chatbots in analyzing large data sets. This reduces pattern matching work.

3. Decision Tree-Based

The way this chatbot works is arguably less user-friendly. Because the user must follow the order of answers that have been programmed by the bot engine. This method can be complex or simple depending on how the concept is designed.
However, many business owners also use this method because it is low in complexity, faster, and still useful in responding to user inquiries. When using it, the user will be faced with several widgets in the form of buttons containing the answer text.

4. Contextual

To be able to create conversations naturally, contextual chatbots rely on artificial intelligence systems with machine learning (ML). This method is indeed the best compared to the previous method.

Advantages and Disadvantages of Chatbot

Advantages Disadvantages Image

Chatbots have several advantages, including:
1. Make it easy for users to find out the detailed information needed.
2. Faster and more practical in responding to information.
3. Can always be used 24 hours as long as the server is on.
4. Easy to develop.

In addition to the shortcomings, among others:
1. Cannot answer information that has not been created by the developer.
2. Keywords must match those that have been set.
