# Topic Modelling on Financial News Articles
## Summary
This repo contains code for pre-processing and vectorizing raw text collected from 85,000 news articles downloaded from a variety of online broadsheet newspapers and newswires covering finance, business and the economy.

The data was pre-processed with the removal of stop words, punctuation and numbers, and the words were stemmed using the Snowball stemmer.
The data was vectorized into a TF-IDF matrix, then Latent Semantic Analysis techniques were applied to reduce the dimensions into a smaller number of latent features.
Finally, the latent features were clustered into topic clusters and the trends in the topics visualized over time.
## Outcome
