After some behind-the-scenes testing on newspaper content and newspaper blogs, I've added OpenCalais tagging to my blog to see how it does in a live setting.
OpenCalais is a free service of Thompson Reuters that scans unstructured (text) content and extracts named entities (people, places things), facts, and events. This can be used to support the so-called "semantic Web," leading eventually to smart applications that do our research for us.
The OpenCalais project has released quite a bit of supporting software, including a Drupal module that I'm using.
The immediate result is that the number of tags on my blog postings is going to grow rapidly. One of the things I want to understand better is how those tags can be used to generate smart "related items" links on websites.
