What is a chatbot?
A chatbot is a computer program made specifically to simulate a conversation with human users, especially over the Internet. It can be thought of as a virtual assistant that communicates with users via text messages and helps businesses get closer to their customers. It is worth mentioning that chatbots are designed to imitate communication with a person. The transmission itself can take place, for example, via a chat interface or a telephone call. Developers usually plan chatbots so that it is difficult for users to determine whether they are talking to a human or a robot.Automate 84% of user questions

Why do you need chatbots?
Chatbots help any business or organization achieve the following goals:- Improving work efficiency.
- Automating the fulfillment of customer requests.
- Processing basic requests free up employees to work on complex and higher-value requests.
- Multilingual support.
- Save time and effort with automated customer support.
- Increasing responsiveness and customer engagement.
- Communication personalization.
Features of chatbots
When creating a modern bot uses artificial intelligence based on machine learning and natural language processing (NLP — Natural Language Processing). AI provides the smoothest interaction between humans and computers. Chatbots are everywhere, whether it be a bank site, a pizzeria, or an e-commerce store. They help serve customers in real-time on several predefined questions related to business activity. In this case, the bots use natural language and create the illusion of communicating with the person. Simplistically we can say that chatbots are evolving systems of questions and answers using natural language processing. Nowadays, chatbots on Python are very popular in the technological and corporate sectors. Companies in many industries adopt these intelligent bots to skillfully simulate the natural human language and communicate with people. Everything from e-commerce companies to medical facilities uses this innovative device to gain an advantage in business.How does a chatbot work?
Chatbots are nothing more than software applications with an application layer, a database, and an API. Simplifying how a chatbot works, we can say that its operation is based on pattern matching to classify text and issue a suitable response to the user. The chatbot responds to the user according to the program embedded in it. Bots come in different types, depending on how they work. There are three main types:- Chatbot based on rules. It is a basic chatbot. The user interacts with the bot using predefined parameters. To get a response from the bot, the user must select the desired option. These bots receive a user request, parse it, and then offer the results in the form of buttons. Typically these bots are used to replace FAQ sections. However, this is not the best solution when it comes to complex queries.
- Independent chatbots with keywords. These are bots using machine learning. Unlike rule-based chatbots, they analyze what the user wants and react accordingly. These bots use custom keywords and machine learning to respond more efficiently and effectively to user queries.
- NLP (or contextual) chatbots. At the moment, they are the most advanced. These chatbots are a combination of the best rule and keyword-based chatbots. They use natural language processing to learn the context of requests and user intent and act accordingly.
Automatic question and answer
Automatic chatbots, also known as an automated system of questions and answers called differently because of the different scenarios. The answer to the question refers to the task of using computers to automatically answer the questions posed by users according to user requirements. Unlike existing search engines, the system answers to the questions is an advanced form of information service. The system returns a list of users, not books, sorted by keyword and precise answers to natural language. In recent years, with the prompt growth of artificial intelligence, automated responses to questions have turned to the direction of research, which has attracted a lot of attention and broad development prospects.- Understanding of the issue: If you specify a user’s question, automated questions and answers must first understand the user’s query. Semantic interpretation of user problems includes several vital technologies, such as lexical analysis, parsing, and semantic analysis. It is necessary to comprehend the semantic content contained in the text with different dimensions.
- Extracting text information: Automatic answers to the questions should collate relevant information in the present case, the knowledge base, or the library of solutions to the questions and derive appropriate responses.
- Justification Knowledge: In automatic mode, questions and answers because of the limited coverage of the case, the knowledge base, and the library of questions and answers are not all questions can be answered directly. For this, it is necessary that these implicit responses were obtained by studying knowledge in the existing system of knowledge.
Building a chatbot using the NLP framework
At the heart of any chatbot is understanding the user’s intent. If the user’s request is misunderstood, the chatbot cannot give the correct answer either. For understanding, the information and relevant objects in the user’s request are retrieved, and the appropriate dialog is started. The chatbot should be trained on a series of (in this case, very manageable) conceivable conversational processes. If the user makes an entry that the dialog assistant can’t do anything about, the system sends a query to the search index. Such a search index serves as a searchable data structure that contains each requested document and its associated meta-information. Standard search engines like Solr or Elasticsearch can be used to enable fast data queries for the chatbot platform.How to make a chatbot in Python?
Numerous methods help you explore the technique for creating a chatbot in Python.Prepare Dependencies
Step one in creating a Python chatbot with the ChatterBot library is setting up the library on your system. It’s best to create and use a new Python digital environment for customization. You must write and run this command in your Python terminal to take action. Now that you have your setup ready, we will move on to the next step of your way to build a chatbot using Python.Import classes
Importing lessons is the second step in creating a Python chatbot. You have to import two tasks — ChatBot from chatterbot and ListTrainer from chatterbot.Create and run a chatbot
The chatbot you create will be categorized as an NLP chatbot. Here, the argument (corresponding to the parameter name) represents the name of your Python chatbot. If you want to disable the bot’s learning ability after training, you can use the «read_only = True» command. Since you must submit a list of answers, you can provide lists of strings that can later be used to prepare your Python chatbot and find the best match for each question.Talk to a Python chatbot
To work alongside your Python chatbot, you must use the .get_response() function. However, it is essential to understand that a chatbot does not know how to answer all your questions. Since its knowledge and training remains very limited, you may have to give him time and provide additional training knowledge to prepare him further.Practice your Python chatbot with an array of data
In this last step of creating a Python chatbot, you must use an existing array of data for additional training for your Python chatbot.The effectiveness of a bot in Python
Most users expect the brand’s quick response to their requests regardless of the time of day. Previously, a timely response was needed to run the around-the-clock customer support, equip jobs for them, and pay wages. As practice shows, the mainstream questions are typical, and they can quickly respond to a properly designed model. Here comes the aid of the creation of a chatbot in Python. The robot can respond simultaneously to multiple users, and paying his salary is unnecessary.Benefits of chatbots
There are numerous advantages of implementing chatbots. Creating a chatbot on Python will allow you to:- Get an additional sales channel because people spend their time on social networks every day. A chatbot is not a site or an application. It does not need to download, which is very popular with users. With it, you will have processing speed, ease, and convenience. Remember, the faster you respond to a request user, the higher sales and profits, respectively, the company will continue to grow.
- Understand your business needs. You can test the development of your strategies and marketing campaign with the help of a bot. As practice shows, users prefer to communicate with chatbots and not download the app.
- Collect feedback from users. If someone asks a question to which the application has no response, it is also only good for business. You get feedback from customers and improve their products.
- To improve the service, conduct surveys and collect information about customers and their interests. Understand their behavior on the network, habits, and purchasing power.
