[Apologies for cross-posting.]<br>
<br>
In the context of enriching the Polish LFG grammar with semantic<br>
representation, we are looking for a set of semantic roles (Agent,<br>
Patient, Beneficiary, etc.) that could be used to mark arguments (and<br>
possibly adjuncts) of verbs and other predicates. This set should be<br>
exhaustive in the sense that it should be possible to assign – more or<br>
less deterministically – a semantic role to any argument (and possibly<br>
adjunct) of any predicate. For this reason the standard – in LFG<br>
textbooks – sets of some 7 semantic roles do not seem sufficient.<br>
Instead, we are looking at larger repertoires proposed in VerbNet, in<br>
FrameNet and in John W. Sowa's work on Knowledge Representation.<br>
<br>
We don't have any strong views about any particular set of semantic<br>
roles, as long as it is exhaustive and applicable to real texts (as<br>
opposed to being merely theoretically interesting). Has anybody in the<br>
LFG community faced a similar task? If so, what set of semantic roles<br>
would you recommend? At the moment, we are wavering between VerbNet and<br>
Sowa's system, both being more manageable than numerous roles offered<br>
in FrameNet, but we are open to other solutions.<br>
<br>
Many thanks, best regards,<br>
<br>
