Re: kamikaze

Does Kamikaze have a mailing list?  It seems like, to me anyway, this  
conversation would be more appropriate for that list as it is about  
Kamikaze, not Lucene.

Re: How to get the similarity between two string vectors?

Yes and no.  You can have a look at More Like This in the contrib  
package.  Additionally, you can just get the TermVectors out of Lucene  
and write your own.  You could use a MemoryIndex which contains one  
document and represent the other document as a query and the "search".

But, no, there isn't a MethodName(Vector1, Vector2) option.

Re: dbsight

Solr (http://lucene.apache.org/solr) can import from a DB, if that is  
what you are after.  I haven't done a full feature comparison between  
DB Sight and Solr, but it appears there is a fair amount of overlap  
based on the front page.

HTH,
Grant

Re: kamikaze

You are right, Grant.Michael, Anmol, let's move this to the kamikaze mailing
list:
http://groups.google.com/group/kamikaze-users

Michael, I have added you by default.

Re: dbsight

Sweet! I'll look more into solr. I wasn't under the impression solr  
could index a database like dbsight.

It's not point-and-clickable, but Solr's DataImportHandler has  
sophisticated configuration capabilities for indexing any JDBC  
accessible database.

And there is also the LuSql project that has recently gotten a lot of  
good press, and I've seen it demo'd first hand it's quite powerful and  
flexible.

And, probably the simplest of all options mentioned above:

Re: [ no subject ]

As per my knowledge, you'd have to index one of the docs  and then run a
query (second doc) to get the similarity score.
Also, the default similarity would take into account more factors than the
regular VSM hence, you'd even have to look into it.
You may write code that on the fly creates a volatile index, runs a query,
returns the similarity and clears the index (which would happen implicitly
in case of a ramdir approach.

Re: Re: [ no subject ]

Thanks Anshum Gupta for the reply,
"As per my knowledge, you'd have to index one of the docs  and then run a
query (second doc) to get the similarity score."

which docs do you mean?  do you mean i have to create a doc for each Vector, do you mean somthing like this:
Vector1 =<"term1","term2","term3"> --->doc1.add("id",new Field ("term1"+"term2"+"term3",Field.Store.YES,Field.Index.TOKENIZED));
Vector2 =<"term4","term5","term6"> --->doc1.add("id",new Field ("term4"+"term5"+"term6",Field.Store.YES,Field.Index.TOKENIZED));
or 
Vector1 =<"term1","term2","term3"> --->
doc1.add("id",new Field("term1",Field.Store.YES,Field.Index.TOKENIZED));
doc1.add("id",new Field("term2",Field.Store.YES,Field.Index.TOKENIZED));
doc1.add("id",new Field("term3",Field.Store.YES,Field.Index.TOKENIZED));

Vector2 =<"term4","term5","term6"> --->
doc1.add("id",new Field ("term4",Field.Store.YES,Field.Index.TOKENIZED));
doc1.add("id",new Field ("term5",Field.Store.YES,Field.Index.TOKENIZED));
doc1.add("id",new Field ("term6",Field.Store.YES,Field.Index.TOKENIZED));

and then get the similarity score between the two docs?
please help.
thanks in advance.
Kamal
