[Pellet-users] ANN: Pellint 0.1

[Evren Sirin]

We are happy to announce the release of Pellint 0.1, an ontology lint 
tool for detecting and fixing performance problems in ontologies. You 
can download Pellint or try the online demo at

http://pellet.owldl.com/pellint

The goal of Pellint is to help Pellet users detect when reasoning with 
an ontology will be slow. Predicting the reasoning performance for an 
ontology is not an easy task, and what we do in Pellint is to define 
patterns that will detect some patterns known to be problematic for 
reasoning. Unlike the traditional lint tools, the problems found by 
Pellint do not necessarily indicate a modeling error in the ontology. It 
just means that Pellet is probably going to be slow when reasoning with 
that ontology. The fixes suggested by Pellint should also be used with 
care. These fixes do not generally preserve the semantics of the 
ontology; e.g. Pellint will suggest to change the meaning of some terms 
in the ontology in order to improve the reasoning performance.

Pellint comes with a set of predefined patterns and documentation about 
these patterns that will get you started. We will be providing more 
explanation regarding these patterns at the C&P blog.

We would be happy to hear your feedback, especially whether the results 
returned by Pellint for your ontologies are helpful or not.

Cheers,
Evren
