LIMES is a link discovery framework for the Web of Data. It implements time-efficient approaches for large-scale link discovery based on the characteristics of metric spaces. It is easily configurable via a web interface. It can also be downloaded as standalone tool for carrying out link discovery locally.
I often end up running a big SPARQL query (usually on a server), exporting the results a TSV, and post processing the results with some combination of vi, perl, awk, sort etc., then loading the processed data into a copy of Excel to get stats out of it, or produce a chart or whatever.
The other day I was wondering if you could pull results directly from a SPARQL endpoint into Excel. Well, it turns out that you can, via something called an Internet Query File.
