[Classifier4j-devel] Simple Implementation

[Kashif <ks...@ai...>]

Hi

 

I am doing a research on Bayesian filters. I am trying to implement
classifier 4J and will appreciate a bit of help.

 

Please note that I am doing a very basic implementation, without using a
JDBC Connection. Later I might move on to JDBC and MySQL.

 

Background:

I am using searchterm and arrays for my blacklist, whitelist and baylist (ie
potential emails for Bayesian Filtering).

 

            SearchTerm blackSt = new OrTerm(blackListSearch);

            SearchTerm whiteSt = new OrTerm(whiteListSearch);

            SearchTerm baySt = new NotTerm(new OrTerm(blackListSearch));
//  If not in BlackList

    

            Message[ ] blackMsgs = folder.search(blackSt);

            Message[ ] whiteMsgs = folder.search(whiteSt);

            Message[ ] bayMsgs = folder.search(baySt);       // These are
the messages which I want to filter with bayesian

    

    System.out.println("No of messages found in whitelist : " +
whiteMsgs.length);

    System.out.println("No of messages found in blacklist : " +
blackMsgs.length);

    System.out.println();

    System.out.println("No of messages ready for bayesian filter : " +
bayMsgs.length);

 

            //Implementation of Bayesian Classifier 4J

            

            IWordsDataSource wds = new SimpleWordsDataSource();

            IClassifier classifier = new BayesianClassifier(wds);

            

            System.out.println("Matches = " + classifier.classify("This is a
sentence") );

    

 

Here's the problem:

1)       I understand that I have to train the filter, need to know how I
can do it.

2)       Is it possible to use a flat file (ie text file) rather than jdbc
connection
