In this era, the moment has arrived to move away from disease as the primary emphasis of medical treatment. Although impressive, the multiple techniques that have been developed to detect the diseases. In this time, there are some types of diseases COVID-19, normal flue, migraine, lung disease, heart disease, kidney disease, diabetics, stomach disease, gastric, bone disease, autism are the very common diseases. In this analysis, we analyze disease symptoms and have done disease predictions based on their symptoms. We studied a range of symptoms and took a survey from people in order to complete the task. Several classification algorithms have been employed to train the model. Furthermore, performance evaluation matrices are used to measure the model's performance. Finally, we discovered that the part classifier surpasses the others.

Most people around the world use social media in their daily lives as a result we can see that it has become an integral part of our lives. Moreover, many people use social media for their livelihood. Social media has a lot of influence on our life from different aspects. Although there are many positive aspects, the trend of negative comments on social media has become a serious problem these days. Through this study, we have detected bad comments made in the Bengali language on social media using machine learning algorithms and measured those performances. Although much work has been done on this issue in other languages, it is scarce in the Bengali language. We have used six different types of machine learning algorithms for this study and the algorithms used are Logistic Regression (LR), Multinomial Naive Bayes (MNB), Random Forest (RF), Support vector machine (SVM), K-Nearest Neighbor (KNN), Gradient Boosting (GB). Among all the algorithms used in this study, SVM gave the best results with an accuracy of 85.7%.

Almost all Bengalis who own smartphones also have social media accounts. People from different regions occasionally employ regional Slang that is unfamiliar to outsiders and confuses the meaning of the sentence. Nearly all languages can now be translated thanks to modern technology, but only in very basic ways, which is a concern. Bengali Slang terms are difficult to translate due to a dearth of rich corpora and frequently occurring new Slang terms developed by people, making it impossible for speakers of other languages to understand the context of a sentence in which Slang is used. We developed a solution to this issue. To create models that can detect Bengali Slang terms from social media, we gather various Slang phrases from various regions and develop a modest corpus. Our suggested method nearly always succeeds in extracting Bengali Slang terms from fresh material. We create a total of 7 supervised models and assess which is the most effective for our study. One of them has a 70% accuracy and 86% recall rate for successful identification. Our models may be linked to the social media platform's backend to restrict the use of Bengali Slang in posts, blogs, comments, and other areas.
