Sarcasm conveys a meaning which contradicts the literal meaning, and it is mainly found on social networks. It has a significant role in understanding the intention of the user. For detecting sarcasm, we used deep learning techniques based on transformers due to its success in the field of Natural Language Processing (NLP) without the need for feature engineering. The datasets were taken from tweets. We created new datasets by augmenting with external data or by using word embeddings and repetition of instances. Experiments were done on the datasets with different types of preprocessing because it is crucial in this task. The rank of our team was consistent across four subtasks (fourth rank in three subtasks and sixth rank in one subtask); whereas other teams might be in the top ranks for some subtasks but rank drastically less in other subtasks. This implies the robustness and stability of the models and the techniques we used.

In this research, the multispectral satellite images have been subjected to unsupervised classification based on K-Means clustering using Hadoop Framework, which is designed for big data processing, along with Hadoop Image Processing Interface (HIPI). We developed support for the GeoTIFF format, which is usually used for satellite images, and we will show that our methodology enhances the performance.
