  In this paper, we describe NoVRol, a semantic role lexicon of Norwegian verbs. We start from the NorVal valency lexicon, which describes the syntactic frames of 7.400 verbs. We then enrich each of these frames by annotating, based on the VerbNet annotation scheme, each argument of the verb with the semantic role that it gets. We also encode the syntactic roles of the arguments based on the UD annotation scheme. Our resource will faciliate future research on Norwegian verbs, and can at a future stage be expanded to a full VerbNet

  This paper reports on efforts to improve the Oslo-Bergen Tagger for Norwegian morphological tagging. We train two deep neural network-based taggers using the recently introduced Norwegian pre-trained encoder (a BERT model for Norwegian). The first network is a sequence-to-sequence encoder-decoder and the second is a sequence classifier. We test both these configurations in a hybrid system where they combine with the existing rule-based system, and on their own. The sequence-to-sequence system performs better in the hybrid configuration, but the classifier system performs so well that combining it with the rules is actually slightly detrimental to performance.

  It is well known that vanilla LFG+Glue overgenerates when it comes to scope ambiguities. This has both theoretical and practical implications: it generates unattested readings, and also produces many spurious ambiguities which do not correspond to linguistically relevant differences. We propose a solution in keeping with the LFG philosophy: a new level of the parallel projection architecture, called proof-structure, which can be used to limit scopal interactions. Unlike earlier attempts to solve this problem, the modularity of our approach means that we do not need to alter the underlying linear logic or proof algorithm of Glue Semantics, with the effect that existing analyses and tools continue to be relevant and usable.

  We discuss the role of enhanced Universal Dependencies (E-UD) in the task of deriving semantic predicate-argument structures from UD treebanks in a universal, non-language-specific way. We consider the usefulness of three kinds of E-UD annotation (controllers of xcomps, propagation of outgoing dependencies in coordinations, and coreference in relative clauses) and assess some heuristics for automatically adding such enhancements. We conclude that one large obstacle both for deriving predicate-argument structures from UD treebanks and for the automatic enhancement of basic UD treebanks is the fact that UD does not represent empty elements such as pro-dropped arguments, and we suggest that devoting effort to this would often provide a better return on investment than spending resources on improving or adding E-UD annotations.
