Presently more and more tools come up in the Web 2.0 – Domain, which bring semantic technologies into blogger´s everyday life. Zemanta was for sure a break-through in annotation of blog entries. I’m running this service on my private and my corporate blog. It is easy to integrate in every common blog-software and it is really a save of time in my daily work. Unfortunaly it is avaible only for english blogs.
Another service which came up recently is Quintura, which provides search capabilities for your own blog with a visual map of tags or hints based on an index created of the own blog entries. It is easy to customize for the own blog’s style with the use of a simple interface. Quintura offers code-snippets to copy to your blog-post or sidebar. Even if it is no semantic search engine in the narrow sense, Quintura provide a fine semantic-like interface for a meaning-sensitive search. See how Quintura is implemented into The Semantic Puzzle at our sidebar.
