17 Search Innovations Outside Google

I was digging through my bloglines bookmarks today and found this old (for a blog) post on the Red/WriteWeb written by Nitin Karandikar, author of the Software Abstractions blog.

The post, entitled Top 17 Search Innovations Outside Google, provides a great round-up of recent search innovations. It was posted in May. I’m guess I’m better late than never in sharing it.

Here’s the summarized list:

• Natural language processing
• Personal relevance
• Canned, specialized searches
• New content types
• Restricted data sources
• Domain-specific search (aka, vertical search)
• Parametric search
• Social input
• Human input

• Classification, tag clouds, and clustering
• Results visualization
• Results refinement and filters
• Results platforms
