I assume you mean http://jens-lehmann.org/files/2014/swj_dbpedia.pdf. For the enrichment topic (5.11) you would actually not need parsing and feature extraction as the task would be to develop a DL-Learner plugin for Web Protégé not directly interact with the extraction part of the framework. For the life science extraction, we would still have to see how and whether extraction framework modifications are necessary. A large part of the alignment to life science ontologies can be done via the mappings wiki and in postprocessing via link discovery (using LIMES - http://aksw.org/Projects/LIMES.html). You can also ask general DBpedia developer questions (and those seem to be general) in the developers list: https://sourceforge.net/p/dbpedia/mailman/. > 3.DL learner- The DL learner helps in creating a framework following > description logic.

First, you have to distinguish between "Protégé" which is a desktop application and "Web Protégé" which is a web application and thus more suitable for collaborating on the DBpedia ontology. In order to work with SWRL, you would need the following: 1.) SWRL support in Web Protégé, 2.) SWRL-Support in DL-Learner and 3.) some consensus in the DBpedia ontology group to use SWRL (there is a dbpedia-ontology list to which such a question could be posted - see the above link). So while it is not impossible to do, it would be a larger project, whereas the use of OWL (which builds on description logics) is already established in DBpedia. > I would be grateful if you could tell me more about the project and > suggest a systematic approach (like warm-up tasks) so that I can learn > more about the project. I added the other mentors in CC as well. We hope to be able to provide more information.
