Hi Greg,
it depends what meaning you put behind" ontology-guided entity
extraction ".
There are two major possibilities:
- you put in an ontology and KIM automatically start extracting
instances from the ontology classes: this is not supported. and there
is no obvious way to do it with reasonable quality.
- you put in an ontology - usually extending PROTON as a basis; and
you reuse or develop extraction pipelines to find entities from the
classes of interest: this is exactly what KIM is meant for.

Thanks for the information.
Also, do you have any information related to using KIM for ontology-
guided entity extraction ?
Thanks,

Hi Greg,
this was a 3rd party hyperbolic tree applet, when it was still
considered cool. At some point we have removed it from the
distribution, as its behavior had some specifics - sometimes
floating to the sides; and also quite unreadable with anything
beyond a dozen nodes.
So there is no such functionality by default. Given that such graph
visualization tools have an API and KIM has API for exploring the
entities - such integrations are very natural and some customers
choose graph visualization tools.
For small descriptions - this is fancy for bigger - say - you want
to see a big part of the KB - it doesn't work at all. We have
invested time in researching alternatives, that utilize space better
than a graph: 3D graph representations projected on a 2D plane; and
Voronoi treemaps, but we have nothing to show still.

Please see the brief note below.
Can you point us to any instructions/documentation related to the

Thanks.

The Graph.jsp page is still there. However, I don’t see any
references that point to the page.

This (below) is what I was referring to in the meeting - but i'm
not sure if the platform still supports this.
If so - it would be very interesting to see it in action.
Rick -
Thanks again for the demo today.
That was very useful and I think there are significant
opportunities for SD in this space...
