Beyond OntoNotes Coreference  

Recent years have seen considerable progress on the notoriously difficult task of coreference resolution owing in part to the availability of coreference-annotated corpora such as MUC, ACE, and OntoNotes. Coreference, however, is more than MUC/ACE/OntoNotes coreference: it encompasses many interesting cases of anaphora that are not covered in the extensively investigated MUC/ACE/OntoNotes entity coreference task. This talk examines several comparatively less-studied coreference tasks that are arguably no less challenging than the MUC/ACE/OntoNotes entity coreference task, including the Winograd Schema Challenge, zero anaphora resolution, and event coreference resolution.

Syntactic-semantic parser for Polish  

The author will present the parser being developed within CLARIN-PL project, its morphological pre-processing, a categorial grammar of Polish integrated with valency dictionary and used by the parser and the semantic graph formalism used for meaning representation. It will also discuss algorithms used by the parser and optimization strategies, both related to performance and concise representation of ambiguous syntactic and semantic parsing trees.
