Evri's Garden Sprouts Some Search

I just published a blog post titled Evri's Garden Sprouts Some Search @ blog.evri.com. Here is a snippet:

We thought about launching a labs site where we could showcase our latest gadgetry, but decided none of us really fancy wearing lab coats. Many of us have gardens, however, and a few of us wear overalls, so we figured we'd instead start a garden to sprout new ideas. So, voila: we have a new section of our site called Evri's Garden where we'll be showcasing our fresh but not fully farmed veggies. Our first garden sprout is Evri Search, which I'll spend some time chatting about.

Evri Search exposes our text analysis infrastructure that automatically identifies and makes available linguistic links connecting people, places and things found on the web. To provide this enhanced search capability, Evri Search performs an exhaustive deep natural language processing based analysis of every sentence in our corpus. This search interface allows you to directly interact with the same back end system our scientists and engineers use everyday to fine tune the algorithms used in our applications to search on your behalf. The help section on the search page is pretty exhaustive, so I thought it would be more entertaining to just walk through some interesting queries.

One of my favorite queries is to find corporate acquisitions. To do so using the Evri query language (EQL), I can construct a query like:


In this query, I am asking the system for all sentences containing a grammatical clause where the source of an action is a named organization (usually companies but also non profits and government agencies), the action is the verb buy (or similar verbs), and the target of the action is also a company.
