Thanks Lorenz! I'll have to play with it some more to see if I can't add the right property assertions. Thanks Again, Steve THIS MESSAGE IS INTENDED FOR THE USE OF THE PERSON TO WHOM IT IS ADDRESSED.

Subject: Re: [DL-Learner discussion] Learning A Super Class Hi, ok i checked it and built a conf file in our new format (see attachment). It works, but i think that this is not the solution you expect. The problem is that the DL-Learner learns only based on the information about instances. In your case, there are only the class assertions known, but you should also give them the explicit property assertions, e.g. that "iS123 hasNext iS456".

I haven't tried it yet, but I'll take a crack at running things through the 2011-12-08 beta release to see if I get different results. I've attached the files I'm using. The commented out class Seq123 in test.owl is the class expression I'd ideally like to learn. The instance conf uses individuals for positive/negative examples. test.conf uses classes for positive/negative examples. While putting together the attached files and re-running everything once more before sending it your way, I discovered a typo in one of the URI's in the instance conf file. When I fixed this, DL Learner executed quickly and was able to produce some results. While not the class expression I was hoping for, it still completed! I still can't get things working with the class level positive/negative examples; DL learner still eventually runs out of heap with the test.conf file.

Which version are you using? Regards, Lorenz On 18.01.2012 20:42, Steve Hookway wrote: Hello All, I'd like to learn a particular sequence of numbers. I'm using this pattern: http://ceur-ws.org/Vol-216/submission_12.pdf to create class expressions that describe sequences. I've created a number of example sequences and would like to learn the expression that captures them all: eg given 4123, 1235, 123, etc and some negative examples, I'd like to learn the class expression for a list containing sequence 1,2,3. This task would essentially find the superclass for the positive examples (a list containing 1,2,3). The DL learner examples I've come across use individuals for positive and negative inputs, but is there any reason classes couldn't be used? I've tried this and eventually run out of heap space with 1.5 G RAM - but wonder if there is anything intrinsically wrong with this approach. I've also given each class a named individual and made the individuals the positive and negative examples. But, DL Learner also eventually runs out of heap space.
