    (Proceedings of the 2019 8th International Conference on System Modeling and Advancement in Research Trends, IEEE, 2020-06-16) Hossain, Rakib; Ahamed, Fowjael; Zannat, Raihana; Rabbani, Md. Golam
    In today's world business are becoming online based. Companies sell their products and seek for consumer's feedback. When all the consumer writes their review about that's a product, It's becomes difficult to say that product is good or not based on their review. That's where Deep learning come. By using this, we can extract opinion or sentiment from the text which is written by the consumer. This is sentiment analysis. It can classify the emotional status of that review. Our project detects opinion from consumer's review whether it is good or bad. We use SVM, Naive Bayes algorithm and some methods. We use the Naive Bayes algorithm because we want to know how often words occur in the document. And then we use SVM for classifying whether words are positive or negative. For our researching purpose, we use the Amazon consumer review data set, which was available online. Some methods that we are using for preprocessing and cleaned the document where just words are left. We trained our model so well with twenty-four thousand data. So, it will give us the best accuracy and we make this model with the best algorithm and after that, it gives the accuracy of 98.39%. This project will help us in real life when we are having trouble with product reviews. Our machine will help us to determine which review is good and which review is bad and make a category of a positive and negative review and saves our time.

    Shahbagh protest and nationalism: A study on urban social movement in Bangladesh
    (University of Dhaka, 2015-03-31) Rabbani, Md. Golam
    This thesis aims to find out the relationships between urban classes and life style patterns and the impact of modernization and globalization on the urban life style patterns of the people in Narayanganj, and find out a new pattern of consumption. The society of Bangladesh has seen major cultural changes due to the influence of various processes namely, modernization, urbanization and globalization. Narayanganj, a major city of Bangladesh is also currently going through the process of cultural change. The life style pattern of high income groups or the upper class is quite different from the life style pattern of lower income groups or the lower class. The middle income groups of Narayanganj also lead a different way of life. The changing process involves the food habits, media habits, dress patterns and family structure. There is a growing tendency of fast food culture among the upper and middle class people in Narayanganj city though the lower class are less influenced by the fast food culture. A large number of brand shops are situated in Narayanganj city and they are rapidly increasing due to the growing preferences of the upper and middle class people on brand clothes. In addition, Indian hindi and bangla channels are becoming more popular among the residents of Narayanganj city. The modernization and globalization process have a crucial effect in the life style patterns of the people in Narayanganj city though the social stratification factors holds a significant position in this explication of change.
