I recently saw a cool feature that was once available in Google Sheets: you start by writing a few related keywords in consecutive cells, say: "blue", "green", "yellow", and it automatically generates similar keywords (in this case, other colors). See more examples in this YouTube video. I would like to reproduce this in my own program. I'm thinking of using Freebase, and it would work like this intuitively: Retrieve the list of given words in Freebase; Find their "common denominator(s)" …

Where can I find free spatio-temporal dataset for download so that I can play with it in R ?

I'm going to start my degree thesis and I want to do a fault detector system using machine learning techniques. I need datasets for my thesis but I don't know where I can get that data. I'm looking for historical operation/maintenance/fault datasets of any kind of machine in the oil & gas industry (drills, steam injectors etc) or electrical companies (transformators, generators etc).
