What this challenge is about.

You are provided with a dataset of 10,000 customer reviews (in English) with no labels. Your task is to preprocess the text, develop a sentiment classification model using NLP techniques (e.g., bag-of-words, TF-IDF, or word embeddings), and evaluate its performance. You must also produce a report summarizing key findings, such as common complaints or praised features. Success means achieving at least 80% accuracy on a held-out test set and delivering a clear business recommendation.
