Entity Extraction from Websites to MongoDB

Project Description

I have an immediate need to extract company, people, and event entities from different websites (including news websites) and populate the results into my MongoDB. Digital Reasoning's tool Synthesys (http://www.digitalreasoning.com/uncommon-technology) seems to do what I need; however, I need someone who can set everything up for me or recommend something better.

1. Recommend an existing open source or commercial tool to extract and resolve company and people entities using only the already built-in fields for those objects (eg. addresses, name, etc.).  No customization required.  Open source preferred (to run on my server) but not required. 
2. Install the tool (if necessary) / turn it on.
3. Add a few destination URLs and RSS feeds
4. Send the output to my MongoDB instance

My developer will help with whatever setup is necessary on our servers.
