Re: Tags and Folksonomies

[Richard Noble]

Hi

I have not actually done this yet, but will need to do something similar.
We will also be using user tagging, and ratings to influence relevancy for
the searches.

I take it that you want something like if a document has been tagged 8
times with the tag "tagvalue"
but only 4 times with the tag "othervalue" then you want to boost rate the
tag tagvalue higher?

The route I plan to go down would be to store the tag value count against
the document, and
use a (possibly custom) function to boost accordingly.

Just a theory at this point, and I am sure that there may be better ways.

Hope it helps

Richard

Re: Apache solr issue after configuration

[Richard Noble]

Solr newbie here, but this looks familier.

Another thing to make sure of is that the plugin jars are not ialready
loaded from the standard java classpath.
I had a problem with this in that some jars were being loaded by the
standard java classloader,
and my some other plugins were being loaded by Solr,
so QueryResponseWriter was not an instance of
VelocityResponseWriter due to the classloader differences.

They should be loaded by Solr's classloader.

Regards

Richard
