bayesian classification over tsvector - Mailing list pgsql-general

I was wondering if there is some apps, technique, tool to get
inspiration or just use to classify rows according to a weighted
tsvector.

Each row contain a tsvector obtained concatenating 4 rows with
different weight.

I've a corpus for each group.

I'd like to classify the rows that haven't been assigned to a group
already.

thanks
