An Inventory of Preposition Relations
This work addresses a specific linguistic problem for NLP researchers, but it appears incremental as it builds on existing disambiguation tasks without introducing a new paradigm.
The paper tackled the problem of defining semantic relations expressed by prepositions by building on word sense disambiguation, resulting in an inventory that maps preposition senses to relation labels by collapsing semantically related senses across prepositions.
We describe an inventory of semantic relations that are expressed by prepositions. We define these relations by building on the word sense disambiguation task for prepositions and propose a mapping from preposition senses to the relation labels by collapsing semantically related senses across prepositions.
