When I created a java class using this code I was able to do a recompile and poke around and make changes if I wanted.  One could have just commented out the code that needed the URLReaderAgentCustomizer.java  but that would eliminate the eintire URL Reader which was the only agent I could get to work reliably.  The first snapshot is the gui that pops up for the infofilter.  I was also able to get the code from the author who got back to me right away.

The code appears to be pretty close with most difference being in organization and structure.  For consistency's sake I decided to try out this code also.  I seem to have the same issues with the code running intermittently.  Looking the code over in more detail shows that there really isn't much error checking and it is quite possible that there are errors that causing timeouts and looping between the server and client.  The most bizzare thing is that behavior is not consistent at all one website will work great and then just stop working.  I tried different times and even opened up all ports on my router to see if this was the cause but to no avail.





This is the opening sequence you can teach the filter to learn by going to profile and clicking on customize.  You will see this window after you start up customize.





Click on Train NNs to train teach the filter agent how to learn.  You can also add different words that are more to your liking or remove ones you dont like.  One can use this interface to teach. the agent a couple of ways to gather information.  Either in cluster netowrk which will find what words happen in clusters or in rating network which learns based off of the ratings of past news articles.





One can also use the URL reader agent to read webpages and rate how interesting they are.  This is the dialog that won't open without the added class.  I was unable to get most webpages to work without freezing the computer.  The fipa one that is preprogrammed into the code by the author works.  One can also add other sites to the code by going into the class given above and adding urlcombobox items.  In order to do this you need the added class, either the one from the author or the one decompiled.




This is what we see if we run the urlreader on fipa.org  It scores the page a twelve and says it is interesting based off of the words we associated with it in the training. 
The news reader I have had a very difficlut time with.  It doesn't seen to work very consistently and also chews up the CPU.  The intro gui looks like this.




I however, got errors using this NNTP server.  It appears as if we do not have permission to access this server.  I therefore was able to look for a free one online and found freenews.netfront.net  which  kind of worked.  Here is an example of an error if the NNTP server is spelled incorrectly or if it just can't find it.




Here is an example of the correct implementation.



Using this implementation I was able to access some news sites and download some articles but could never get the code to finish downloading it would always lock up. Here is an example of what the agent looks like after you start downlaoding news group articles.  I could only get the newsreader agent to download at most two articles before freezing up. 

The overal effectiveness of these agents wasn't very good.  i was only able to look at a couple of diiferent test cases fully becuase they kept locking up.  I tried a bunch of different websites in the url reader and wasn't able to make it work consistently.  I would get differeing reuslts for the same page.  I even made a page and posted it and tested it out sometimes it works sometimes it doesn't.  I tried to see if it mattered if I had doenloaded the url already and it didn't seem to matter as it would freeze and no info would even be relayed to the console.  (http://geocities.com/dustinbaier805/fuzzy2.html )  This was my test page.  This particular agent gives you an idea of how powerful agents could be collecting data and allwoing you to never miss news articles that interest you.  It also is the first one that we have dealth with that has the capability to learn.
