Real-Time Top-R Topic Detection on Twitter with Topic Hijack Filtering

Real-Time Top-R Topic Detection on Twitter with Topic Hijack Filtering Real-time topic detection on Twitter streams is challenging due to the massive volume and speed of tweets. The authors propose a streaming non-negative matrix factorization (NMF) algorithm that can detect topics in real-time from Twitter data. The algorithm uses stochastic gradient descent to update topic distributions incremen
