# Logic programming semantics

### From ONTOLORE

Different competing semantics have been developed for logic programming. While for the basic paradigm the well-founded and the stable model semantics are by most researchers considered to be the most important ones, the quest for suitable semantics for expressive extensions is still ongoing. Our work concerns a systematic comparative analysis of logic programming semantics, based on so-called *level mappings*.
