Semantic Sig.ma
August 3, 2009
We’ve found a tool that offers results from multiple and varied (and sometimes unrelated) Web sites by using semantic analysis of embedded site data. It’s called Sig.ma, http://sig.ma/. What it returns is a mashup, a bulk treatment of data that may or may not help you. As the site explains: “It might be noisy but you can spot gems, e.g. interesting description differences in different sources.” Sig.ma can be a data browser, a widget to paste into e-mail or HTML, or a semantic API.
Sig.ma is also interactive and capable of learning; if you delete an item it will process that info to exclude that data next time. The catch right now is that only pages exposing RDF, RDFa or Microformats will appear. So while Google spiders the web like crazy, Sig.ma is delving into more specific caches of information. Does this mean Google is lagging behind Sig.ma’s services: Sindice, Kkam, and Boss? We’ll see what the future holds for semantic search.
