Sindice is a Semantic Web index with a search engine. . (Here is the link: sindice.com). Interestingly, one of its authors is Nova Spivack from Radar Technologies, the same guy who runs twine.com. Is this the semantic search engine twine talks about ? Sindice claims to offer semantic search for terms and properties or triples, but personally, I can hardly notice the benefit of using it - It is only capable of indexing things, it is not capable of extracting terms' relations with other terms - something the Semantic Web is about. Why would I need a semantic index or a search through that index. Probably the best application of these services would be making of semantic piped tasks. The Sigma search engine is aggregating definitions for the terms from different sources, and what I really like about it is the ability for the users to control the sources of the definitions. Sigma can export the search results in various formats, such as RDF or JSON, but I am really having hard time to see the benefits of it without getting the relations of the terms.
In general, Sindice has some fancy marketing, but what it really has under the hood remains to be seen. Personally I don't think there is much to brag about.
