4, essential concepts relevant to chatbot technology are described. 3, some issues about the association with chatbots are discussed, while in Sect. 2, we briefly present the history of chatbots and highlight the growing interest of the research community. The rest of the paper is organized as follows. Communication reliability, fast and uncomplicated development iterations, lack of version fragmentation, and limited design efforts for the interface are some of the advantages for developers too. Knowledge in the use of one chatbot is easily transferred to the usage of other chatbots, and there are limited data requirements. Chatbots are integrated with group conversations or shared just like any other contact, while multiple conversations can be carried forward in parallel. Moreover, payment services are integrated into the messaging system and can be used safely and reliably and a notification system re-engages inactive users. Contact to the chatbot is spread through a user’s social graph without leaving the messaging app the chatbot lives in, which provides and guarantees the user’s identity. Most implementations are platform-independent and instantly available to users without needed installations. They became so popular because there are many advantages of chatbots for users and developers too. ![]() They are useful in applications such as education, information retrieval, business, and e-commerce. Chatbots are also known as smart bots, interactive agents, digital assistants, or artificial conversation entities.Ĭhatbots can mimic human conversation and entertain users but they are not built only for this. In the lexicon, a chatbot is defined as “A computer program designed to simulate conversation with human users, especially over the Internet”. It is a computer program, which responds like a smart entity when conversed with through text or voice and understands one or more human languages by Natural Language Processing (NLP). A chatbot is a typical example of an AI system and one of the most elementary and widespread examples of intelligent Human-Computer Interaction (HCI). Intelligent agents can do a variety of tasks ranging from labor work to sophisticated operations. KeywordsĪrtificial Intelligence (ΑΙ) increasingly integrates our daily lives with the creation and analysis of intelligent software and hardware, called intelligent agents. Our engagement with the subject so far, reassures us of the prospects of chatbots and encourages us to study them in greater extent and depth. Furthermore, we present the general architecture of modern chatbots while also mentioning the main platforms for their creation. ![]() After clarifying necessary technological concepts, we move on to a chatbot classification based on various criteria, such as the area of knowledge they refer to, the need they serve and others. Moreover, we highlight the impact of social stereotypes on chatbots design. Next, we discuss the motivations that drive the use of chatbots, and we clarify chatbots’ usefulness in a variety of areas. In this paper, we first present a historical overview of the evolution of the international community’s interest in chatbots. The use of chatbots evolved rapidly in numerous fields in recent years, including Marketing, Supporting Systems, Education, Health Care, Cultural Heritage, and Entertainment.
