Using Machine Learning to Classify News Articles
Approach
Our goal was to build a model to discern the credibility of an article based solely on its textual content.
Data Collection
Collect news articles from a set of credible and non-credible websites. Get training labels from OpenSources, a professionally curated database.
Sampling
Sample from our corpus in such a way that the training set contains an even number of unique articles from both credible and non-credible sources for each day of data collection.
Classifier
Build an ensemble classifier that considers the predictions of two separate models:
1. "Content-only" model (Multinomial Naive Bayes)
2. "Context-only" model (Adaptive Boosting)
Daily Learning
Each classifier is retrained daily and subjected to cross validation testing to obtain updated accuracy scores. These scores are used to update weights in the final ensemble classifier.
