I'll be delving into text mining applications for my master thesis and I need data for it. Ideally, I would need a corpora of texts/news articles from some single (or multiple) credible and authoritative source covering financial markets/economy and the like, spanning a time period as long as possible.
It turns out that there is data somewhat what I'm looking for: the Wall Street Journal corpus or Reuters corpus. The problem is that these datasets have many texts for each day, but spanning only few years time.
For my purposes, I would be more interested to have only a few texts/news articles for each day/workday but the whole corpora spanning a decade or more.
Does anyone know of datasets/corporas that would suit my requirements?
Any other possibilities/ideas to construct one such dataset using open resources?
