Text classification of Wikipedia articles
You are required to use Python and Scikit-learn for this project.
Classify the Wikipedia 300 dataset (150 articles about Video games, 150 about Programming) using machine learning. The dataset can be downloaded at the Datasets page.
For text classification the bag-of-words approach where you convert an article to word counts are typically used. An improvement is TF-IDF (Term Frequency-Inverse Document Frequency) which is used to convert from word counts to word frequencies. TF-IDF is especially useful if the size of the articles varies a lot. Suitable algorithms for text classification are Multinomial Naïve Bayes (MultinomialNB) and Support Vector Machines with linear kernels (LinearSVC).
