Dear DL-Learner developers and users,
in the past year, we performed a lot of changes in the DL-Learner
framework and widened its scope to other machine learning problems in
the Semantic Web apart from learning OWL class expressions. To give you
a preview of those changes, we made an alpha release of DL-Learner
today. Our plan is to follow up with further pre-releases until we can
roll out a stable version again.
Warning: We expect this alpha release to be quite unstable and
documentation is not complete yet. Please report issues or feature
requests here: http://sourceforge.net/tracker/?group_id=203619
Release download:
http://sourceforge.net/projects/dl-learner/files/DL-Learner/
Here is a summary of the changes since the last stable release (from
2010-08-07):
* support for new learning SPARQL queries - see http://autosparql.dl-
learner.org for a demo (QTL algorithm)
* support for learning almost any OWL axiom given a SPARQL endpoint as
background knowledge
* support for enrichment of large knowledge bases (just run the
enrichment script provided in the release to get an overview)
* preliminary support for learning fuzzy OWL class expressions
contributed by Jousé Iglesias
* transition to Maven (http://en.wikipedia.org/wiki/Apache_Maven) -
allows easy inclusion of DL-Learner in your Maven projects:
http://dl-learner.org/wiki/Maven
* new DL-Learner configuration based on Spring
(http://www.springsource.org) - IMPORTANT: the conf file syntax has
changed, so you will need to adapt existing files
* transition to OWL API 3.1, Jena 2.8.8, Pellet 2.2.2, HermiT 1.3.3
* more examples for applying DL-Learner
* numerous bug fixes and smaller enhancements in overall close to 1000
Subversion commits from 12 contributors
Thanks to Lorenz Bühmann, Chris Shellenbarger and Sebastian Hellmann for
their work on DL-Learner.
Kind regards,
Jens
