[Classifier4j-devel] Comparing Documents

[Colin B. <co...@ga...>]

Hi all

I would like to start with saying what an exciting piece of software 
C4J is thanks to all those involved.

I have written a bit of code to use C4J to compare documents (in this 
case stored in a JDBC database) to each other and find out how similar 
they are. I pick the document from which I am to compare, and then add 
each word of it to a SimpleWordsDataSource using a loop 
(wds.addMatch(wordList[i])). I then use BayesianClassifier(wds) to get 
the result of each document.

Problem is that my results are obviously very poor (always 0.99, 
sometimes 0.5) because I don't have any non-matches. Does anyone have 
an idea on how I could do this? What could I possible use as 
non-matches, or am I missing a trick?

Many thanks

Regards

Colin
