Short description of ontology
The "semantics" ontology is tailored to the specific needs of games, played in PAL (quiz & sorting game). For this, we deviate from the FrameNet Frame semantics (which would require heavy modification & extension as it is very general) and developed a simple frame semantics, oriented along thematic roles.
This ontology was meant to be a reference point for natural language generation and interpretation, to specify which frames are used in the project. This should also support multilinguality, linking concrete realizations in the different languages to the abstract concept as, e.g., Multilingual WordNet does.

Ontology design
For the development of a frame sementics, oriented along thematic roles, we define a most general concept sem:Frame with the usual "suspects", viz., properties sem:agent and sem:patient typed to sem:Actor, property sem:theme, typed to sem:Entity (the superclass of Actor), and property sem:manner, typed to sem:Manner. Thus, these properties are all valid for subclasses of sem:Frames, as, for instance, sem:Answering, sem:Asking, sem:BeingCorrect, sem:Continuing, or sem:Playing. The subclass sem:AssigningRole defines a further property of its own, viz., sem:purpose, typed to sem:Frame. Thus this property will allow us to represent a role assignment to a specific participant, e.g., assigning the person who asks, the person who plays, etc.
Evaluation and results
The ontology in the current state is very much work-in-progress and would require some more labour to be of common use.
