Introduction
1.1 Background of the research
Cyberbullying, trolling, hate comments and fake news are some of the critical concerns of society. According to the digital world, more than 27% of the youth are affected and harassed because of the rise in cyberbullying and telling. The use of the internet has created several damages to the minds of the child. More than 13% of the children have been found under clinical depression due to the ill effects of cybercrimes (Olweus & Limber, 2018). The Jump Tech Blog estimates for example that Facebook connections constitute 50 % of total falsified news website traffic and 20 % of the total flagship website traffic. Since the majority of U.S. adults –62%– gets news on social media (Jeffrey and Elisa, 2016), being able to identify fake content in online sources is a pressing need. Germany also decided that if it failed to delete illegal content on time, social media companies would face a fine of $60 million. Denmark and Canada have legislation that prohibits all speeches with abusive or offensive material directed at minorities and which could encourage violence and mental disorders. The Indian government has also called for the required action against hate speech, especially in posts that hurt religious sentiments and trigger social uproar, from prominent social media sites like Facebook and Twitter. The false information circulated on the internet is the result of various drastic changes undertaken by the youth. Therefore, the research study aims to provide specific technological solutions to bring a decisive move against the ill effects of cyberbullying.

Literature Review
2.1 Concept of Deep Learning
Deep learning is a branch of artificial intelligence that is designed to imitate the human brain and its working capabilities. Deep learning also termed as a deep neural network or deep neural learning is a type of automated learning in which computers get to know and understand the universe in terms of the hierarchy of concepts. Since the machine gathers knowledge, it is not required to officially define aspects of the human-machine operator. It is the methods, in which the processing of the data is possible to detect the objects, to recognize the speech, and in the translation of the languages. Deep learning makes it possible to learn representations for data with multiple levels of abstraction from the machine model consisting of multiple layers of computation. The state of the art in speech recognition, visual objects recognition, object detection, and many others such as drugs and genomics have been greatly enhanced with these methods. Deep learning exposes a complex structure in large data sets by using the backpropagation algorithm to show how a computer will change the internal parameters used to measure the display in each layer in the previous layer. Deep learning is created and processed in such a way that it can comprehensively analyst and take up the decision, just like the human can (Chang, 2018).
Applications including natural language processing, language recognition, computer vision, on-line suggestions, bioinformatics, and videogames are studied as a part of deep learning techniques used by industry professionals like profound feedforward networks, regularization, optimization algorithms, convolutional networks, sequence modeling and realistic methodology. Deep learning has already proved useful across other areas, such as computer vision, audio and voice processing, natural language processing, robotics, bioinformatics and chemistry, video games, search engines. The networking system of deep learning is an integrated structure; each layer is comprehensive to be built on the previous layers; therefore, with added information regarding hosts, senders, and others.
2.2 Concept of Prediction System in Deep Learning
The prediction system is the term referred to understand the processed algorithm. The algorithm is trained on the databases before acting as an output. The prediction system is well understood and the outcome of the forecast of the new data is similar to some extent. The algorithm of the prediction system is meant for the generation of the values for each recorded data. It helps model builders to get the most value and identifiable resources for data (Yan et al. 2018).
The prediction system is mostly utilized in deep learning when determining the next predicted action in any strategy. Prediction systems have become a crucial research field to promote reliability and productivity in the new manufacturing industry. Internet of Things and cyber manufacturing methods help capture vast amounts of sensor data, which then provides support and enables effective processing and analysis of data using deep learning. In the deep learning neural system, the prediction system helps in the allowances of the business to have the most accurate guesses for the outcomes that are related to the associated data. For example, Prediction systems have played a significant role in the planning, inventory management, and quality assurance of plant maintenance. It is the first step for companies to predict the tangible value of the business. The deep learning mechanisms help in the development of the specific huge currency model of prediction to prevent losing the customers.
2.3 Hate Speech
Hate speech is the kind of statement that is directed to spread hatred among the people either for one particular person or for the entire community. The hate speech can be directed towards the person for the city that is based on the specific race, sex, orientation, and so on. The term hate speech is a debatable topic in the present day as it is often considered to have collided with freedom of speech. In many countries, the laws have identified hate speech to be anything that provokes violence in the country. That can be any kind of gesture, any type of writing format, or any type of conduct. The hate speech laws are divided into two forms: the first one intends to preserve order in public and the second one is to protect the dignity of humans. The internet has become the platform for spreading hate speech by extremist organizations. However, several rules are implemented to stop spreading such propagandas (Gamback & Sikdar, 2017).
2.4 Cyber Bullying
Cyberbullying, which can also be termed as cyber harassment, is the kind of harassment that takes place using electronic media or the internet. It is also popularly termed as online bullying. In simpler words, cyberbullying can be referred to as the usage of technology to harass, torment, humiliate, threaten, or intimidate the target person. The expansion of the digital circle and digital technologies has mainly raised the platform for the bullies to be indulged in such activities (Lee & Shin, 2017). There are several platforms, from which cyberbullying can be done; these are through social media, messaging apps, forums, email, and so on.
Any platform, in which the information can be shared, becomes the platform for cyberbullying. Cyberbullying can be of different types, such as doxing, harassment, cyberstalking, impersonation. When the information of the targeted individual is published online to defame and humiliating, it is termed as doxing. When the hurtful or threatening comment is sent to the victim, online or directly to them is termed as cyber harassing. To...
