Hit count estimation for Tversky Similarity

Hi,

I can see from the docs how to get an estimated count of Tanimoto Similarity above a certain threshold:

select jchem_core_pkg.get_hit_count('SCHEMA', 'TABLE', 'COLUMN', 'c1ccccc1', 't:t simThreshold:0.99') from dual

Is there a simple way to do this for the Tversky Similarity metric?

 

Thanks muchly

 

Derek

Hi Derek,

Is there a simple way to do this for the Tversky Similarity metric?

With current JChem versions, there is not. Therre will be starting with JChem 5.3 through a search option which can be used to specify the metric. (Currently the metrics [those few supported in JChem Cartridge] are available through separate operators only.)

Peter

Thanks Peter.  Is there a rough estimate of when 5.3 might be released?

All the best

 

Derek

 

Derek,

It is currently scheduled for Monday, 16 November, 2009.
