OntoClass

Rappresentano la classe ontologica per nomi e verbi. Utilizziamo i Topics di Open Multilingual Wordnet, conosciuti anche come lexicographer files su Princeton WordNet. Non li utilizziamo per aggettivi e avverbi dato che non è presente una gerarchia per queste due classi.

Aktionsart

E' possibile specificare l'aktionsart dei verbi. Abbiamo utilizzato lo schema di etichette da UniMorph, distinguendo però tra classi azionali e tratti.

• Tratti:

Trait	Label	Definition
Atelic	ATEL	The event has no terminal point/culmination.
Durative	DUR	The event can extend over a time span.
Dynamic	DYN	The event is dynamic (i.e, it is not a static situation)
Punctual	PCT	The event does not extend over a time span, has no duration.
Telic	TEL	The event has a terminal point/culmination.

• Classi (e corrispondenti combinazioni di tratti):

Class	Label	Traits
Accomplishment	ACCMP	DYN, TEL, DUR
Achievement	ACH	DYN, TEL, PCT
Activity	ACTY	DYN, ATEL, DUR
Semelfactive	SEMEL	DYN, ATEL, PCT
Stative	STAT	ATEL, DUR

Un elemento può essere constrained rispetto a una classe; tuttavia in alcuni casi può essere utile specificare un tratto per includere più classi che condividono quel tratto.
