In the first episode of 2009, we welcome Leigh Dodds, Benjamin Nowack and Peter Mika as Gang regulars, and talk with Tom Tague of Thomson Reuters about this week's release of version 4.0 of the Open Calais service.

Towards the end of the call, Gang members talk about Marshall Kirkpatrick's recent Read/Write Web report asking if Google were adopting a more structured and semantic approach to the delivery of query answers.

During the conversation, we refer to the following resources;

'Harnessing the Deep Web, Present and Future' [PDF] (as referred to by Leigh Dodds, and further discussed on his blog here)
