2. Semantic role labeling (SRL), also known as shallow se-mantic parsing, is an important yet challenging task in NLP. 2.1 Semantic Role Labeling SRL annotations rely on a frame lexicon containing frames that could be evoked by one or more lexical units. Not only the semantics roles of nodes but also the semantics of edges are exploited in the model. A lexical unit consists of a word lemma con-joined with its coarse-grained part-of-speech tag.1 Each frame is further associated with a set of pos- 2) We evaluate and analyse the reasoning capabili-1https://spacy.io ties of the semantic role labeling graph compared to usual entity graphs. Semantic role labeling (henceforth, SRL) is the task of identifying the semantic arguments of predicates in natural language text. mantic role labeling including argument extrac-tion. Given an input sentence and one or more predicates, SRL aims to determine the semantic roles of each predicate, i.e., who did what to whom, when and where, etc. siders the semantic structure of the sentences in building a reasoning graph network. In this paper, we show that language models may be used to select sentences that are more useful to annotate. Figure 1: Example semantic role annotations for the two verbs in the sentence I want to hold your hand. This would be time-consuming for large corpus. Annotation of data is a time-consuming process, but necessary for many state-of-the-art solutions to NLP tasks, including semantic role labeling (SRL). Seman-tic knowledge has been proved informative in many down- 5 … 3 Pipeline for Semantic Role Labeling The limitations of the FrameBank corpus do not allow to use end-to-end / sequence labeling meth-ods for SRL. 32 Prediction of Function Tags versus Semantic Role Labeling 2002.
