In this article, the most essential aspects related to the development and study of chatbots are examined. In the given context, the essential types, particularities of chatbots and methods of creating chatbots at the current stage are studied from the perspective of the development of Artificial Intelligence, Natural Language Processing (NLP) and Machine Learning (ML). The most important achievements in the respective field obtained over time as well as the trends in the development of modern chatbots are examined.

This paper studies encryption and decryption algorithm, using isotopes of Latin groupoid. Cryptographic algorithms are computationally intensive processes which consume large amount of CPU time and space during the process of encryption and decryption. The goal of this paper is to study the encryption and decryption algorithm with the help of the concept of Latin groupoid and notion of isotopes. The proposed algorithm is safe in the implementation process and can be verified without much difficulty. An example of encryption and decryption based on the atin groupoid and the concept of isotopy is examined.
