The creation of this programmed bot is perfectly in line with the principles of artificial intelligence. <\/p>\n\n<p>Also known as a <strong>conversational agent<\/strong>, a chatbot is a discussion robot that imitates human conversations. Users can interact with this web tool via a chat platform: messenger, whatsapp, Twitter, etc. Interaction can also take place via Google Assistant on your cell phone.  <\/p>\n\n<p>What\u2019s more, this programmed bot is increasingly becoming an integral part of many companies\u2019 marketing policies. <a href=\"https:\/\/botnation.ai\/en\/chatbot-advantage\/\">Chatbots offer many advantages<\/a>, particularly in terms of communication and <strong>customer relations. Since customer satisfaction remains the top priority for any company, adopting a tool like a chatbot will be highly beneficial in this respect.<\/strong> <\/p>\n\n<p>On the other hand, the chatbot can also help the company with certain simple tasks. Also, this bot can be a quick way for customers to access company-related information.  For example, a customer requesting information on the company\u2019s products or services can receive automatic responses to their query. <\/p>\n\n<p>What\u2019s more, this programmed bot enables the company to improve its quality of service to customers. Chatbots are also renowned for <strong>improving the user experience<\/strong>. Customers can therefore use the company\u2019s services without difficulty.  <\/p>\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/botnation.ai\/wp-content\/uploads\/2022\/02\/ai-chatbot-smart-digital-customer-service-application-concept-3-1024x591.jpg.webp\" alt=\"\" class=\"wp-image-1447\"><\/figure>\n\n<h2 class=\"wp-block-heading\" id=\"comment-fonctionne-un-chatbot\"><span class=\"ez-toc-section\" id=\"How_does_a_chatbot_work\"><\/span>How does a chatbot work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>To <strong>program a chatbot in Pyython<\/strong>, it\u2019s essential to first understand how this <strong>web service<\/strong> works. In reality, it\u2019s a piece of software capable of interacting and communicating with <strong>customers<\/strong> just like a human being.  You wonder how this is possible. <\/p>\n\n<p>That\u2019s because the chatbot uses Natural Language Processing (NLP). This concept has two components. The first is Natural Language Understanding (NLU). This is the chatbot\u2019s ability to understand the<strong>user<\/strong>\u2018s language. The second is Natural Language Generation (NLG).     This is the robot\u2019s ability to produce text similar to what humans say. <\/p>\n\n<p>In practice, when a customer asks a question, Botnation divides the sentence into two elements: intent and entity. The first designates what the user is looking for. The second gives details of the entity. It is thanks to this automatic study that the chatbot can understand the queries and provide different <strong>response<\/strong> proposals.   <\/p>\n\n<h2 class=\"wp-block-heading\" id=\"que-faut-il-avoir-pour-creer-un-chatbot-en-python\"><span class=\"ez-toc-section\" id=\"What_do_you_need_to_create_a_chatbot_in_Python\"><\/span>What do you need to create a chatbot in Python?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Having a project to create a chatbot can be beneficial in the long term. To <strong>develop a chatbot<\/strong>, you\u2019ll need a few things. These include the NLTK Deep Learning library. Without it, you can\u2019t proceed with <a href=\"https:\/\/botnation.ai\/en\/chatbot-creation\/\">chatbot creation<\/a>.    If this is the first you\u2019ve heard of it, it\u2019s a Natural Language Processing toolbox. <\/p>\n\n<p>Several models are available. You can opt for Keras. Using the Python programming language, this library can do all the natural language processing you need.  <\/p>\n\n<h2 class=\"wp-block-heading\" id=\"comment-se-presente-la-structure-du-projet-de-creation-d-un-chatbot\"><span class=\"ez-toc-section\" id=\"How_is_a_chatbot_project_structured\"><\/span>How is a chatbot project structured?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>You want to <a href=\"https:\/\/botnation.ai\/en\/messenger\/\">create a Messenger chatbot<\/a> on your company website. You should be aware that this is a project involving a number of operations. To help you, here\u2019s a list of the files you\u2019ll need to assemble as you develop your chatbot. These include :   <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Gui_chatbot.py<\/li>\n<\/ul>\n\n<p>This is the file that will be used to create the user interface. <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Train_chatbot.py<\/li>\n<\/ul>\n\n<p>This is the file in which you will create and train the deep learning model.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Intents.json<\/li>\n<\/ul>\n\n<p>This file stores all the data required to create the model. <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Words.pkl<\/li>\n<\/ul>\n\n<p>This directory contains all the unique words making up the model\u2019s vocabulary.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Classes.pkl<\/li>\n<\/ul>\n\n<p>This is the file that saves the names of the tags to be classified for better prediction of <strong>responses<\/strong>.<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Chatbot_model.h5<\/li>\n<\/ul>\n\n<p>This is the hierarchical file in which the weights and architecture of the model formed will be stored at the end.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"quelles-sont-les-etapes-a-suivre-pour-developper-un-chatbot-de-botnation\"><span class=\"ez-toc-section\" id=\"What_are_the_steps_involved_in_developing_a_Botnation_chatbot\"><\/span>What are the steps involved in developing a Botnation chatbot?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p>Now that you\u2019ve got an idea of the project\u2019s structure, you\u2019re probably wondering how you should go about <strong>programming a Botnation chatbot<\/strong>. <\/p>\n\n<h3 class=\"wp-block-heading\" id=\"l-importation-des-donnees\"><span class=\"ez-toc-section\" id=\"Importing_data\"><\/span>Importing data<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>The first thing you need to do is import the modules required to develop your chatbot onto the platform. To do this, go to the <a href=\"https:\/\/botnation.ai\/en\/chatbot-instagram-python\/\">Python interface and create<\/a> the Train_chatbot file.  Only then can you proceed with the import. <\/p>\n\n<h3 class=\"wp-block-heading\" id=\"le-pre-traitement-des-donnees\"><span class=\"ez-toc-section\" id=\"Data_pre-processing\"><\/span>Data pre-processing<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Once this has been done, you need to perform some preliminary processing on the loaded data. Several techniques can be used. Tokenization and lemmatization are the most common. The first involves dividing sentences into words and adding them to the intent file.    The second is to gather lemma words into a class. <\/p>\n\n<h3 class=\"wp-block-heading\" id=\"la-programmation-des-donnees\"><span class=\"ez-toc-section\" id=\"Data_programming\"><\/span>Data programming<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Now you can program the data. To do this, you\u2019ll need to convert each pattern into numbers. Create a list of 0s of the same length as the number of all words. Finally, set the indexes containing the word in the templates to 1.   <\/p>\n\n<h3 class=\"wp-block-heading\" id=\"la-formation-du-modele\"><span class=\"ez-toc-section\" id=\"Model_formation\"><\/span>Model formation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>The next step is to train the model. Start by adjusting the data using the \u201cSGD\u201d optimizer. Then train the epochs.   Finally, save the model using the Keras model save function. <\/p>\n\n<h3 class=\"wp-block-heading\" id=\"l-interaction-avec-le-robot\"><span class=\"ez-toc-section\" id=\"Interacting_with_the_robot\"><\/span>Interacting with the robot<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p>Now that the template is ready, you\u2019ll need to create the cat\u2019s graphical interface. You can save it in the gui_chatbot.py file. All that\u2019s left is to capture a <strong>user<\/strong> message, pre-process it and enter it into the template to see if it generates the expected <strong>responses<\/strong>.  <\/p>\n\n<p>Here\u2019s how to design a chatbot in Python.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You\u2019re a company and you want to communicate effectively with your customers.
