Chatbots Using Machine Language: Mood Analyzer and a Political Commentator

Ujjwal Nayan, Amity Institute of Information Technology (AIIT), Amity University, Noida, Uttar Pradesh


The use of chatbots is rapidly increasing in various fields such as customer service, healthcare, education, and e commerce. The advancement in Natural Language Processing (NLP) and Machine Learning (ML) techniques has led to the development of more sophisticated chatbots that can understand and respond to human language in a more effective manner. OpenAI is a world-renowned artificial intelligence research organization dedicated to advancing the capabilities of AI and making it more accessible toindividuals and businesses alike. One of their latest offerings is a powerful AI language model called GPT-3, which is used to develop a Mood Analyzer and a Political Commentator chatbot. This research paper aims to explore the features and functionality of the Mood Analyzer and Political Commentator chatbot in OpenAI's GPT-3 model, and how they can be used to analyze and interpret human emotions and political discourse. By leveraging machine learning algorithms, a comprehensive analysis of text data could be performed, enabling users to gain insights, and understanding into the sentiment and topics discussed in the text input.

In this work, the influence of gamma irradiation on the self diffraction pattern, third-order Reflective index and Gaussian laser output profile properties of Pyronin G (C17H10ClN2O) solution has been reported. Gamma-ray irradiation was performed by using a 137Cs source with an exposure rate of 0.56 Gy/min. The pure pyronin G sample and irradiation pyronin G for different times of exposure to 21, 42 and 62 KGy γ rays for the concentration 0.08 mM have been investigated via a typical absorbance spectrum and characterized in the wavelength range 033–703 nm. The self diffraction patterns and non-linear refractive index and change refractive index , , showed concord change with different irradiation doses. Also, the diffraction rings profile of the samples have been studied using 532 nm continuous wave (cw) laser (Solid-State-Laser -532-100T). This study also suggests that gamma radiation can be considered a tool for the improvement of device properties among other applications.
