Project Name: FollowThis

   Project Lead(s): Matt Terenzio
   

Big Goal for MoJo Hackfest:

  • Ship some usable code. (achieved)
  • Learn how to manage an Open Source project.
  • Work with others on related projects. (achieved)
  • Drink heavily. (achieved)

Key steps toward goal:

  • 1. need to be able to extract RDFa, Microformats from pages.
  • 2. Need to be able to use NLP to extract entities if Semantic metadata is not present.
  • 3. Need to be able to store and query the metadata.
  • 4. Need a solid UI for users to be able to interact with the service.
  • 5. A crawler for the news sources would be nice.

Pending needs:

  • Important:Need to make a button that is an embeddable widget for ease of deployment
  • I have a working bookmarklet but it needs work. JQuery help. (still need a session with jquery expert)
  • Totally clueless on entity extraction from pages that don't have semantic metadata. (solved somewhat)
  • Also need to figure out SPARQL and the best persistent data store for RDF. (Laurian gave me some good starting points)

Link for more info:

  • rNews has been brought up. I've installed the RDFa distiller from W3C and you can use it to distill RDFa from pages.
   Example which distills a page with rNews in it: 
   To use it, just call:
http://followth.is/cgi-bin/RDFa.py?uri=uri-of-we-page-youwant-to-distill
  • (update: Matt has a better entity extractor than this using Stanford NLP -- will use that) To extract keywords from some text I set up a CGI script that does so if you feed it text.

example

It should accept posts to that URL as well as gets.

  • First pass at a readability-like way to extract the article text and headline from a web page:

http://followth.is/read/article/http%3A%2F%2Fwww.thehour.com%2Fstory%2F511535%2Ffrank-fay-way-we-were/

  • Another endpoint that distills RDFa froma web page (this one in PHP)

http://followth.is/transform/?type=rdfa&url=http://www.thehour.com/story/511535/frank-fay-way-we-were

  • A SPARQL endpoint for the triplestore of rNews data

Where from here:

  • Though code is in working form, it is necessary to clean and organize a few parts for better forward maintainability and extension
  • Continue to work on open alternatives to some of the portions that use third party APIs
  • Documentation for both developers and users
  • Promote rNews adoption
  • Deploy to at least one news site by end of 2011
