django-rdflib and postgresql - the best of both worlds — EuroPython 2011: Florence, June 20–26
rdflib is a python library implementing a database with various triples back-end, parser, data serializers, SPARQL is a Python interface to extract/insert triples. We integrated it in Django reusing the database connection and exposing an ORM interface, along with full-text search on literals. This presentation shows a django-rdflib case study with a PostgreSQL backend in Brain Architecture Management System (http://brancusi1.usc.edu) - a neuroscientific project for the University of Southern California. Benefits of the flexible RDF structure will be shown, allowing researchers to insert free format data, making data public with a customizable serialization and use the powerful full-text search integrated in PostgreSQL.

CommonCrawl
Common Crawl produces and maintains a repository of web crawl data that is openly accessible to everyone. The crawl currently covers 5 billion pages and the repository includes valuable metadata. The crawl data is stored by Amazon’s S3 service, allowing it to be bulk downloaded as well as directly accessed for map-reduce processing in EC2. This makes wholesale extraction, transformation, and analysis of web data cheap and easy. Small startups or even individuals can now access high quality crawl data that was previously only available to large search engine corporations.

The False Choice of Schema.org | The Beautiful, Tormented Machine
Some of you may have heard that Microsoft, Google and Yahoo have just released a new uber-vocabulary for the Web. As the site explains, if you use schema.org, you will get a better looking search listing on all of the search listings for Bing, Google and Yahoo. While this may sound good on the surface, it is very bad news for choice on the Web. There are few points that I’d like to make in this post:

BeyondTrees and the New York Times: Using Lucene to build a time machine
Imagine you can see 160 years of history, all on one screen. You can zoom and pan, you can look at a particular day, you can even do a search. And when you do, the results come up not as a list, but as a heat map that shows where in history that topic appears, and how often.
