Joint Apposition Extraction with Syntactic and Semantic Constraints
نویسندگان
چکیده
Appositions are adjacent NPs used to add information to a discourse. We propose systems exploiting syntactic and semantic constraints to extract appositions from OntoNotes. Our joint log-linear model outperforms the state-of-the-art Favre and Hakkani-Tür (2009) model by ∼10% on Broadcast News, and achieves 54.3% Fscore on multiple genres.

Semantic role labeling systems usually take advantage of syntactic parsing and th...

In this paper we present a semantic role labeling system for Persian, using memory-based learning model and standard features. Our proposed system implements a two-phase architecture to first identify...
