-<ul style="float:left">
- <li>Get learning component fast.</li>
- <li>Get local DBpedia SPARQL endpoint working (next DBpedia release expected at the endof January and then every
- two months, so it would be nice to have a script based partly automated or at least documented solution for
- creating a DBpedia mirror).</li>
- <li>Improve stability: Fix sometimes occurring PHP errors and warnings (check PHP error log).</li>
- <li>For each result, display a "+" which shows more information about the concept in an overlay box, e.g. its
- Description Logic or OWL syntax, its classification accuracy on the examples, and which
- examples it classifies (in-)correctly.</li>
- <li>Create a small number of test cases (e.g. 3), which can be used to verify that DBpedia Navigator is
- working in typical scenarios (in particular cases where concepts with length greater one are learned).</li>
- <li>Make DBpedia Navigator RESTful, e.g. URLs $base/showArticle/$URL for displaying an article;
- $base/search/$phrase for searching; $base/listInstances/$complexClass for listing the instances of
- a learned. Maybe session variables (in particuar the selected positive and negative examples) can
- also be given, e.g. $base/search/$phrase?positives=[$URL1,$URL2,$URL3]&negatives=[$URL4]. The supported
- URI design should be briefly documented (e.g. on a dbpedia.org wiki page). A good URI design allows
- easier external access (just give someone a link instead of saying exactly which actions have to be done to
- get to a state), simplifies debugging the application, and may be of use for creating further
- features.</li>
- <li>[if possible] When expensive SPARQL queries or learning problems have been posed, there should be
- some way to abandon these if the user has already switched to doing something else. Example: The user
- has added 3 positive and 1 negative examples. This is executed as a learning problem, but has no solution (so
- DL-Learner would run forever unless we pose some internal time limit). The user adds another negative example a
- second later, so instead of letting the previous learning problem run for a long time (and needing much resources),
- it should be stopped by DBpedia Navigator.</li>
- <li>[if possible] Find an easy way to validate HTML/JS in AJAX applications.</li>
