Is TF IDF implemented in zope search engine. On NED in Zope.
Hi all, I was reading a paper on News Event Detection (NED) and I started wondering how hard would it be to implement such a mechanism in Zope. My first step was to find out if Zope already implemented a vector space model (tf idf, maybe) for indexing and searching the documents. I know nothing of Zope internals yet. So, I'm counting with your help for me to start digging into Zope's. Best regards and thanks in advance, Manuel.

Zope's search engine (the ZCatalog) does not, but some textindexes ("ZCTextIndex", "TextIndexNG") use something similar to perform their ranking. -- Dieter
