Subject Concept Expansion
Date Sat, 05 Sep 2009 20:21:01 GMT
We would like to support concept expansion in searches, i.e. when a user searches for 'software'
then the system should also search for keywords / phrases such as program <https://owa.de.logica.com/Exchange/176077/Drafts/AW:%20TermsComponent.EML/webwn?o2=&o0=1&o7=&o5=&o1=1&o6=&o4=&o3=&s=software+program>
, computer <https://owa.de.logica.com/Exchange/176077/Drafts/AW:%20TermsComponent.EML/webwn?o2=&o0=1&o7=&o5=&o1=1&o6=&o4=&o3=&s=computer+software>
, system <https://owa.de.logica.com/Exchange/176077/Drafts/AW:%20TermsComponent.EML/webwn?o2=&o0=1&o7=&o5=&o1=1&o6=&o4=&o3=&s=software+system>
, package <https://owa.de.logica.com/Exchange/176077/Drafts/AW:%20TermsComponent.EML/webwn?o2=&o0=1&o7=&o5=&o1=1&o6=&o4=&o3=&s=package>
 and class.
 
I imagine that the right way of doing this is a request handler, which expands a query into
its conceptual similar entries and aggregates the results. A simple change in the filter from;
 
q:software => q:software OR program OR computer OR system OR package 
 
would most likely do the job.
 
Does such a request handler already exist (... looking at the list on the wiki and in the
javadocs the answer seems to be no, but maybe its maintained externally)?
 
And is this the right way to go at all?
 
Thanks,
Gert.
