On welcome page just simply write a query in input box and hit the button.
Sigma page will popup with information related to the query. At the top of the page there are two buttons:
"Add More Info" use it to pull more information about the query
"Start New" use it to create compleatly new sigma
On your right hand side you will see "source manager" area. Sources are displayed on 3 tabs: sources, approved,rejected. In this area you can manage sources by approving the good one, and rejecting poor one. When you reject a source all information which came from it will be removed from your sigma.
There are a few options that can be passed to sigma url:
.. simply join the Web of Data. Markup your pages or the theme of your
content management system with RDFa and Microformats. Once you have
interoperable data online, just make sure you submit it to the
Sindice submit page.
Sig.ma should show your data within a few minutes (about 30).
In order
for your data to be aggregated properly, the ideal thing is to make use
of RDF and make sure that the node which is the main subject of your
description has sufficient metadata to be recognized as such (a proper
label and possibly also other attributes, e.g. class and other
distinguishing properties). While Sig.ma doesn't disambiguate now,
it is expected that future versions will use as many extra properties
as possible to select which entity descriptions to aggregate.
